Top 3 Picks for Best CO2 Mosquito Trap

Top 10 Best CO2 Mosquito Trap in 2026 Compared

This side-by-side overview highlights each trap's attraction system, coverage, power source, capture method, and practical limitations, helping you narrow the field before considering a full review.

1. Biogents Mosquitaire – Genuine CO2 Attraction

4.3Editor scoreCheck price on Amazon

Biogents Mosquitaire Outdoor Trap

CO2 and scent mimicry

500g daily tank setting

Twelve-volt electrical power

Two replacement catch bags

The Biogents Mosquitaire is a dedicated outdoor mosquito trap built around genuine carbon dioxide, human-like scent, and directed airflow. It carries a 4.3 rating, making it a credible, well-regarded option for homeowners who want to attract biting mosquitoes without spraying pesticides or using an electrified killing grid. Its defining feature is the CO2 booster system rather than light alone.

Pros

• True CO2-based mosquito attraction
• Comprehensive accessory package
• Pesticide-free capture approach
• Targets several mosquito species
• Low-noise fan operation

Cons

• CO2 tank not included
• External tank and power required

The package is unusually complete. It includes the trap, CO2 emitter and valve, a Sweetscent lure stated to last up to two months, two catch bags, a funnel net, a 12V power supply, and a 33-foot extension cord. A CO2 tank is not included, so buyers must account for both the initial purchase and continued cylinder supply. The specified emitter rate is 500 grams per day.

The design was developed around mimicking human scent and breath to draw mosquitoes away from occupied areas. The supplied information says this approach captures a broader range of species, including Aedes aegypti and floodwater mosquitoes, while the low-noise fan moves attracted insects into the collection system. That makes it more purpose-built than a conventional light trap, although actual results still depend on placement, local mosquito pressure, and consistent operation.

This is the strongest choice for a buyer seeking authentic CO2 attraction, flexible outdoor placement, and a pesticide-free capture method. It is less convenient for renters or anyone without access to a regulated tank and safe outdoor power. For those who can provide both, its complete accessory set and dedicated mosquito focus justify the added setup.

A More Mosquito-Focused Attraction System

By combining carbon dioxide with scent mimicry and airflow, the Mosquitaire targets the cues mosquitoes use to locate people. The approach is especially relevant in yards where light-only traps may not reflect the strongest attractants in the supplied product information.

Complete Outfit With Separate Tank

Most operating components are included, from the emitter and power supply to catch bags, net, lure, and extension cord. The CO2 cylinder remains a separate purchase, which makes ongoing operating costs and storage requirements important parts of the decision.

2. Mosquito Magnet Patriot Plus – Broad-Acre Counterflow Design

2.9Editor scoreCheck price on Amazon

Mosquito Magnet Patriot Plus

CO2, heat, moisture lure

Up to one full acre

Propane cylinder operation

Fifty-foot power cord

The Mosquito Magnet Patriot Plus uses propane to produce carbon dioxide and adds heat and moisture cues to imitate attractive signals. It has a 2.9 rating, the lowest numerical score among the rated products, but its specification set remains appealing for larger properties. The system is designed to protect as much as one acre and to address mosquitoes, no-see-ums, midges, and black flies.

Pros

• Covers up to one acre
• Targets several flying pests
• Counterflow capture technology
• Long electrical cord
• Continuous low-noise operation

Cons

• Lowest product rating
• Propane tank not included

We may earn a commission when you buy through this link, at no additional cost to you.

Its counterflow technology creates airflow that pulls attracted insects into a secure net trap. This capture-first design is attractive for users who prefer not to surround an active area with a high-voltage grid. A 50-foot power cord adds placement flexibility, while the standard propane cylinder format allows unattended operation without a nearby outlet.

The main compromises are the low rating, the need to supply propane separately, and the requirement for electrical power as well. The product information says one tank can support continuous performance for up to 21 days and that noticeable mosquito reduction may take seven to ten days of continuous use. Those expectations depend on correct placement and sustained operation.

Buyers with a larger yard and room for a dedicated installation may value the one-acre claim and multi-pest targeting. It is less attractive for someone seeking a simple plug-in product, an indoor unit, or the strongest customer rating in this guide. Despite the rating, it remains a technically serious outdoor system for users willing to maintain it.

Designed for Larger Outdoor Areas

The Patriot Plus is built for a broader coverage area than most compact units, with a stated capability of up to one acre. Placement away from people and high-traffic areas helps the counterflow system pull insects toward the trap instead of the household.

Capture Instead of Electric Shock

A secure net captures insects after the lure draws them into the counterflow. This approach avoids the exposed electrical-grid design used by many zappers, making it potentially easier to use around occupied outdoor spaces when installed properly.

3. Dynatrap DT1130SR – Quiet One-Half-Acre Capture

3.8Editor scoreCheck price on Amazon

Dynatrap DT1130SR

UV lamp mosquito lure

Up to one-half acre

Weather-resistant construction

Touch-button basket emptying

The Dynatrap DT1130SR attracts mosquitoes and other flying insects with a lamp and draws them into a catch basket with a quiet fan. Its 3.8 rating reflects a middling customer history, while the weather-resistant construction and stated one-half-acre coverage make it relevant to outdoor buyers seeking a low-profile alternative to a zapper.

Pros

• Generous one-half-acre claim
• Quiet fan operation
• Simple removable catch basket
• Weather-resistant housing
• Replaceable long-life LED

Cons

• No dedicated CO2 output
• Requires nearby electrical power

We may earn a commission when you buy through this link, at no additional cost to you.

The catch basket empties with a touch button, which reduces the inconvenience of handling trapped insects. A long-lasting LED is designed to reduce replacement frequency, and the listed placement guidance is 3 to 6 feet off the ground and 20 to 40 feet away from areas where people relax.

The critical limitation is that the product does not list CO2 as an attraction method. It uses a mosquito lamp and airflow, making it a useful light-and-fan trap but not a true carbon-dioxide system. A buyer whose priority is specifically CO2 should choose a model that explicitly releases or mimics carbon dioxide.

This trap is best for outdoor spaces where a discreet, quiet device and simple basket maintenance matter more than CO2 authenticity. It can also serve as part of a broader insect-control setup because the supplied information identifies flies, wasps, gnats, and other flying insects among its targets. It should not be purchased as a CO2-only solution.

Convenient Basket Maintenance

The removable basket and touch-button release simplify routine servicing. Owners can inspect collected insects and empty the basket without dealing with a glue surface or an electrified grid.

Placement Matters for Light Traps

The recommended height and distance give the trap room to attract insects while keeping it away from areas where people gather. Even with this placement, a light-based device may be less effective when competing with other nighttime illumination.

4. DynaTrap DT152 – Discreet Indoor CO2 Lure

3.9Editor scoreCheck price on Amazon

DynaTrap DT152

UV-LED and CO2 lures

Indoor household placement

Outlet or USB power

StickyTech glue card

The DynaTrap DT152 is an indoor flying-insect trap that combines UV-LED attraction, CO2 attraction, and a suction fan. It holds a 3.9 rating and stands apart from outdoor models with a discreet basket and decorative black finish designed to blend into a room rather than look like industrial equipment.

Pros

• Discreet decorative styling
• Combines light and CO2
• Whisper-quiet fan
• Flexible outlet or USB power
• No exposed electric grid

Cons

• Designed for indoor spaces
• Consumes replacement glue cards

We may earn a commission when you buy through this link, at no additional cost to you.

Attracted insects are drawn into the trap and held on a StickyTech glue card. The product works from a wall outlet or USB port, and the included refill card provides a simple beginning. Replacement DynaTrap 21523 StickyTech cards are sold separately, so regular consumables should be expected during periods of heavy insect activity.

Its strongest attraction feature is the combination of light and CO2, although the supplied information does not describe a separate refillable CO2 supply. The trap targets fruit flies, gnats, moths, mosquitoes, and other common indoor fliers. It is best suited to a bedroom, kitchen, porch-like enclosed area, or other location where a wall-powered device can remain running.

This is not the right option for broad backyard coverage because it is explicitly designed as an indoor trap. It is valuable for users who want quiet, contained insect capture in a specific room and prefer a sealed or glued collection method over an electric grid. For indoor nuisance control, it is one of the more relevant products in this roundup.

Useful for Targeted Indoor Areas

Place the DT152 where nuisance insects are most active, such as near fruit, entry points, or other areas with recurring fly and gnat problems. Its compact powered design makes it more suitable for focused household control than perimeter-wide yard management.

Quiet and Visually Discreet

The fan operates quietly while the decorative basket reduces the visual impact of a traditional trap. A glue-card collection system also avoids exposed high-voltage components in rooms used by children or pets.

5. GOOTOP 4200V Zapper – Simple Light-and-Grid Design

4.4Editor scoreCheck price on Amazon

GOOTOP 4200V Bug Zapper

Ultraviolet attracting bulb

Up to one-half acre

Replaceable 15-watt bulb

4200V electric grid

The GOOTOP 4200V uses ultraviolet light to attract mosquitoes and other flying insects, then kills them on contact with an electrified grid. It has a 4.4 rating, placing it among the better-reviewed products here, and its straightforward plug-in design is attractive for patios, porches, balconies, and other outdoor gathering areas.

Pros

• Strong 4.4 customer rating
• No pesticides or attractants
• Lightweight and easy to hang
• Replaceable long-life bulb
• Simple cleaning tray

Cons

• No CO2 attraction mechanism
• Most effective in darkness

We may earn a commission when you buy through this link, at no additional cost to you.

The product claims coverage of up to one-half acre and lists mosquitoes, Aedes, gnats, midges, several fly types, moths, and wasps among its targets. A replaceable 15W bulb and a removable collection tray make maintenance more manageable. The supplied information also states that the unit is EPA registered and uses physical rather than chemical control.

Despite its relevance as a mosquito-control appliance, it does not use CO2 as an attraction cue. It is also most effective at night and in darkness, when the bulb can compete more successfully with ambient light. Outdoor placement near people requires care because the design uses a high-voltage grid and should remain inaccessible to children and pets.

Choose the GOOTOP for straightforward, pesticide-free zapping where darkness and a safe hanging location are available. It is a good general-purpose flying-insect zapper, but it does not deserve consideration as a dedicated CO2 mosquito trap. The distinction matters if carbon dioxide is central to your search for more targeted mosquito attraction.

Physical Control Without Pesticides

The light-and-grid system removes the need for spray insecticides or chemical attractants. This can be useful for households seeking a nonchemical appliance, although regular tray cleaning remains necessary.

Best Results in Dark Conditions

The product is intended to operate at night or in dark areas where its ultraviolet bulb has fewer competing light sources. Ambient porch lighting, lanterns, and other illumination can reduce its practical effectiveness.

6. Ortho Home Defense – Breeding-Cycle Prevention Focus

3.8Editor scoreCheck price on Amazon

Ortho Home Defense Station

Breeding-site mimic technology

Up to 4,300 square feet

Water and refill band

Thirty-day band replacement

The Ortho Home Defense Mosquito Kill & Prevent system is unlike the other entries because it imitates natural mosquito breeding sites rather than relying on a CO2 lure. It has a 3.8 rating and is designed to attract Aedes and Culex mosquitoes into a contained station, kill adult mosquitoes in nine days, and affect larvae developing inside and around the station.

Pros

• Targets adults and larvae
• No flame, spray, or battery
• Large stated protection zone
• Simple periodic maintenance
• Scientifically researched approach

Cons

• Not a conventional CO2 trap
• Requires water-level checks

We may earn a commission when you buy through this link, at no additional cost to you.

The supplied information says the station protects up to 4,300 square feet. It operates without flames, sprays, or batteries, using water and a refill band. The band is replaced every 30 days, and the water level must be checked and replenished as needed. Two bands are included in the package.

Its educational value is that it addresses more than adult attraction. By encouraging mosquitoes to use the station as a breeding location, it can reduce the emergence of new adults over time. The trade-off is that it is not a conventional CO2 mosquito trap and may not provide the same immediate reduction in biting activity around an occupied patio as a dedicated capture unit.

This product suits homeowners seeking passive, low-maintenance mosquito management and a broader effort to interrupt breeding. It is less appropriate for someone specifically shopping for a CO2-powered catcher. Place it outdoors on level ground in a shaded location near vegetation or other secluded yard areas, following the label instructions.

Targets the Next Generation

The station's breeding-site approach addresses larvae as well as adult mosquitoes. This makes it a complementary strategy for yards where sustained mosquito production remains a recurring problem.

Simple but Consistent Maintenance

There is no battery, flame, or spray to manage. Owners must instead refill water as it evaporates and replace the band on the stated 30-day schedule, making consistency essential.

7. Dual-Lure Outdoor Zapper – Feature-Rich CO2 Mimic

4.7Editor scoreCheck price on Amazon

Dual-Lure Outdoor Bug Zapper

CO2 mimic and body heat

365nm ultraviolet tube

IPX5 moisture-resistant shell

4200V electric grid

The Dual-Lure Outdoor Bug Zapper has a 4.7 rating, the highest among the products with numerical scores. It combines a 365nm UVA bulb, warmth, and a CO2 mimic to attract mosquitoes before delivering a 4200V electric-grid shock. This combination makes it a strong value-oriented choice for patios, gardens, porches, and similar outdoor spaces.

Pros

• Highest rated product
• Three complementary attractants
• IPX5 outdoor moisture rating
• Replaceable standard-size bulb
• Quick-removal cleaning tray

Cons

• Requires covered outdoor outlet
• Uses exposed high-voltage grid

We may earn a commission when you buy through this link, at no additional cost to you.

Its outdoor design includes an IPX5-rated shell, fire-retardant ABS construction, and a protective outer cage around the grid. A 15W warmth source and the CO2 mimic supplement the ultraviolet attraction. The product information lists EPA, RoHS, CE, and FCC marks on the base, adding a useful set of visible compliance identifiers.

Setup is straightforward: hang the unit from a beam, railing, or shepherd's hook and connect it to a covered outdoor outlet. The catch tray twists off for cleaning with the included brush, and the standard 15W 365nm U-shaped tube can be replaced without searching for a proprietary part. These details make long-term maintenance relatively approachable.

The main safety consideration is the live grid, which means the unit should be mounted where children and pets cannot touch it. It also needs an outlet and does not provide the capacity of larger propane systems. For buyers wanting multiple mosquito cues in a relatively accessible outdoor format, however, it is one of the most compelling choices in the guide.

Multiple Attraction Cues Improve Appeal

The 365nm light, 36-degree warmth, and CO2 mimic present mosquitoes with several cues associated with people. This multi-lure approach is more elaborate than a standard ultraviolet zapper and may be especially useful around shaded patio areas.

Built for Outdoor Maintenance

The IPX5-rated shell helps resist everyday moisture, while the cage and fire-retardant ABS construction add protection around the electrical system. A replaceable bulb and twist-off tray simplify the two most visible maintenance tasks.

8. Dynatrap DT2030SR – One-Acre Quiet UV Trap

4.1Editor scoreCheck price on Amazon

Dynatrap DT2030SR

UV-LED insect attraction

Up to one full acre

Weather-resistant housing

Touch-button basket release

The Dynatrap DT2030SR is an outdoor light-and-fan trap with a stated one-acre coverage area. It earns a 4.1 rating and uses UV-LED light to attract flying insects before drawing them into a catch basket with a quiet fan. It is a practical alternative to a high-voltage bug zapper.

Pros

• Large one-acre coverage claim
• No exposed electric grid
• Quiet fan operation
• Discreet black finish
• Simple basket maintenance

Cons

• Uses light instead of CO2
• Needs continuous electrical power

We may earn a commission when you buy through this link, at no additional cost to you.

Its weather-resistant construction is intended for continuous seasonal use, and the long-lasting LED is designed to minimize replacement needs. The sleek black finish allows it to blend into a yard or garden, while the touch-button basket release makes routine cleaning easier than dealing with a fixed collection chamber.

The important limitation is again the absence of CO2. Its attraction depends on ultraviolet light, so performance may be lower in areas with substantial ambient lighting or where the species present respond less strongly to light. Like other fan traps, it needs a suitable outlet and appropriate placement rather than being a completely self-contained outdoor installation.

The DT2030SR is worth considering for a larger property when quiet operation, a one-acre claim, and clean basket-style capture are priorities. It is less suitable for a buyer whose main criterion is authentic carbon-dioxide attraction. Its strongest selling points are coverage, discretion, and maintenance convenience.

Large-Area Light and Fan Capture

The stated one-acre capability makes this one of the larger light-based units in the roundup. It is intended to create a mosquito-reducing zone around a suitably placed installation rather than function as a small indoor device.

Quiet Collection Without Zapping

A whisper-quiet fan moves insects into a removable basket. This avoids the high-voltage grid found in zapper-style products and supports use in outdoor areas where low noise and visual discretion are important.

9. Outdoor CO2 Mosquito Trap – Two-Pack Light Attraction

Check price on Amazon

Outdoor CO2 Mosquito Trap

CO2 and light attraction

Up to 1,100 square feet

Fifty-thousand-hour LED

Collection tray capture

The Outdoor CO2 Mosquito Trap is a two-pack designed to combine CO2 and light to attract mosquitoes into a collection tray. No numerical customer rating is supplied, so it is harder to compare its proven user satisfaction with the rated products. Its two-unit format and chemical-free design may nevertheless make it convenient for distributed outdoor placement.

Pros

• Two traps included
• Direct CO2 attraction claim
• Chemical-free operating design
• Long-lasting LED
• Simple collection tray

Cons

• No published customer rating
• Modest coverage per unit

We may earn a commission when you buy through this link, at no additional cost to you.

The stated coverage is up to 1,100 square feet, which is more modest than the one-acre claims made by several larger systems. A fan draws attracted mosquitoes into a built-in tray, while the LED is rated for up to 50,000 working hours, or approximately six years according to the product information.

Setup is described as easy to install with minimal maintenance, making the system attractive to users who want a two-unit arrangement without a complex setup. The supplied information does not detail whether the CO2 source is refillable, whether a consumable attractant is required, or how each unit is powered beyond mentioning an LED and electric fan, so those points should be confirmed on the listing.

This product may be a good choice for patios, backyards, and outdoor gatherings where two smaller traps can be placed around separate activity zones. It is less compelling for a very large property or for anyone who needs a clearly documented propane, canister, or refill-based CO2 supply. Its two-pack convenience and low-maintenance design are the central attractions.

Two Locations from One Purchase

The two-pack can be split between a patio, garden, or other gathering areas rather than concentrating both units in one location. Distributing traps may be useful where people spend time in more than one outdoor zone.

Low-Maintenance Chemical-Free Operation

The listed design uses CO2 and light rather than chemical attractants, and a fan carries mosquitoes into a collection tray. Owners still need to empty the tray and confirm the CO2 supply method before making a purchase.

10. OWLTRA MT2410 – Premium Multi-Cue Outdoor System

4.6Editor scoreCheck price on Amazon

OWLTRA MT2410 Mosquito Guard

Propane-generated carbon dioxide

Heated body-heat simulation

Counterflow escape prevention

Twenty- and thirty-pound tanks

The OWLTRA MT2410 combines propane-generated CO2, a built-in heater, and a blue-purple UV LED to attract mosquitoes and other biting insects. Its 4.6 rating is the second-highest numerical score in the guide, and the feature set makes it a strong premium option for buyers seeking a complete outdoor installation.

Pros

• Strong 4.6 customer rating
• Multiple human-body mimic cues
• Quiet and odorless operation
• Works in all weather
• Targets several biting insects

Cons

• Propane cylinder sold separately
• Requires careful outdoor placement

We may earn a commission when you buy through this link, at no additional cost to you.

Patented counterflow technology draws insects into a collection box, where the supplied information says they dehydrate within 24 hours. The system targets mosquitoes, no-see-ums, flies, moths, midges, and black flies. It is described as quiet, odorless, suitable for all-weather operation, and designed to avoid harm to beneficial insects such as bees and butterflies when placed correctly.

The propane tank is sold separately, and compatibility extends to 20-pound and 30-pound cylinders. The unit must be installed on level ground in a shaded area away from water sources, obstructions, and open flames. Maintenance includes checking the propane supply, cleaning the collection box, and replacing attractant cartridges every 21 days when optional cartridges are used.

This is the best premium pick for a homeowner willing to provide a suitable cylinder and outdoor installation. Its combination of genuine CO2, warmth, UV, and counterflow capture goes beyond a simple light zapper. The tradeoff is a larger and more involved setup than compact electric traps, but the broad target list and strong rating support a serious mosquito-control purchase.

Human-Signal Mimicking at Scale

Propane releases CO2, the heating unit simulates body heat, and the UV light adds another visible cue. Together these signals give the trap a more comprehensive attraction profile than a lamp-only device.

Quiet, Odorless Collection

Counterflow airflow guides insects into a sealed box where they dehydrate. The absence of an exposed killing grid and the stated odorless, quiet operation make the system well suited to a landscaped yard when installed according to instructions.

Buying Guide – How to Choose the Best CO2 Mosquito Trap

A suitable CO2 mosquito trap should match the size of the area, the mosquito species found there, available power and fuel, and your preference for capture versus electric killing. Review the attraction method and installation requirements before comparing features or customer ratings.

True CO2 and Mimicry

Distinguish devices that release or generate actual carbon dioxide from products that merely use light, fans, scent, or a marketing term such as a CO2 mimic. The Biogents Mosquitaire, Mosquito Magnet Patriot Plus, OWLTRA MT2410, and the Outdoor CO2 Mosquito Trap explicitly use CO2 as part of their attraction system. The DT152 also lists CO2 alongside UV-LED attraction, while the Dual-Lure Zapper uses a CO2 mimic rather than identifying a refillable carbon-dioxide source.

Coverage and Placement

Coverage claims range from approximately 1,100 square feet to one acre or more. Treat these as manufacturer claims rather than guaranteed results, because mosquito density, competing odors, wind, lighting, and placement can all affect performance. Follow the recommended distances carefully: some devices are intended to sit 20 to 40 feet away from occupied areas, while larger CO2 systems need level, shaded ground and open airflow around the unit.

Power and Fuel Requirements

The category includes electrically powered models, propane systems, and the Biogents unit that combines a 12V power supply with a separate CO2 tank. Check whether the outdoor outlet can support the supplied cord and whether the installation needs a covered receptacle. For propane models, account for cylinder compatibility, fuel availability, and a safe storage location. Some listings also require a separate CO2 cylinder, so never assume the tank is included.

Capture Versus Electric Grid

Capture systems draw mosquitoes into bags, nets, boxes, baskets, trays, or glue cards. They avoid exposed electrical grids and may be better suited to shared outdoor areas when placed out of reach. Electric zappers use ultraviolet light, sometimes supplemented by CO2 and heat, to draw insects into a high-voltage grid. They are simple to operate but require greater attention to placement around children, pets, food preparation, and normal household activity.

Environmental and Weather Resistance

Outdoor traps face sun, humidity, rain, dew, and irrigation. The Dual-Lure Outdoor Zapper has an IPX5-rated shell, while several Dynatrap models feature weather-resistant construction. The OWLTRA is described for all-weather use, although the product instructions still call for level, shaded placement away from open flames and water sources. None of these features eliminate the need to protect electrical connections and inspect the unit regularly.

Target Pests and Insect Selectivity

Many CO2 traps are sold for mosquitoes but also list no-see-ums, midges, black flies, gnats, flies, moths, and wasps. Broader target lists can make a device more useful, though they may also increase the number of non-target insects caught. The OWLTRA specifically states that it targets biting insects while leaving beneficial insects such as bees and butterflies unharmed when properly placed. This is still a placement-dependent claim rather than a reason to place the trap near flowers or pollinators.

Noise, Odor, and Appearance

Products with quiet fans and collection baskets blend more easily into patios and gardens than exposed-grid zappers. Several descriptions emphasize low-noise operation, while the OWLTRA is specifically called quiet and odorless. Dark finishes, decorative baskets, and enclosed collection systems may also matter if the device remains visible during gatherings. Placement far enough from seating areas is still necessary because the trap should attract mosquitoes away from people rather than toward them.

Maintenance and Consumables

Fan-and-basket models require regular emptying, electric zappers require tray cleaning, and glue-card traps need replacement cards. CO2 systems may require attractant cartridges, lure refills, propane refills, or separate CO2 cylinders. The Biogents package includes two catch bags and a lure stated to last up to two months, while the OWLTRA's optional attractant cartridges are replaced every 21 days. Confirm the refill process before choosing a model that may be difficult to maintain seasonally.

How to Use and Care for Your CO2 Mosquito Trap

Begin by reading the product's full instructions, identifying every required power or fuel source, and assembling the attractant components before placing the unit. For cylinder-powered systems, connect the tank as directed and confirm that the hose, valve, and fittings are secure. Electric models should be connected to a suitable outdoor-rated outlet or the specified adapter, with cords routed away from standing water and pedestrian traffic.

Place the trap according to the product's guidance, which commonly means level ground, a shaded area, and enough clearance for airflow. Position it away from the patio, picnic table, or other place where people gather so the lure draws mosquitoes away from them. For light-based traps, darkness is particularly important; for CO2 systems, unobstructed airflow and consistent operation are more important than eliminating every nearby light.

Inspect the collection system, catch bags, tray, net, or glue cards on a regular schedule and clean the unit as directed. Check CO2 or propane levels, inspect hoses and connections, and replace attractant cartridges or scent lures when required. Unplug the unit before opening the collection area, and keep electrified grids inaccessible to children and pets.
