Beyond ruining your outdoor summer experiences and being a daily nuisance, mosquitoes are also a public health concern as they can transmit numerous diseases.
For over 20 years, we have harnessed science to offer an innovative mosquito killer with unparalleled results, completely without the use of pesticides.
Let’s work together to sustainably create safe outdoor mosquito protection for you and your loved ones.
This mosquito trap is a good investment for restoring peace and quiet outdoors. When used in combination with a CO2 bottle, its effectiveness is significantly improved, allowing it to capture large numbers of mosquitoes in just a few days. Thanks to its capture system and the use of pheromones, it attracts mosquitoes, thereby reducing their presence around your living space.
Results after 3 weeks of use with the CO2 bottle.
Very effective: the number of mosquitoes on the patio has decreased significantly.
The device was placed in a corner of the garden in the shade of a tree.
We had been plagued by mosquitoes for several years. This trap catches loads of them every day. We occasionally added a CO2 cartridge to increase its effectiveness, and it does indeed attract a wider variety of mosquitoes. Life has been more pleasant since then, but there are still a few left.
I added the kit with a CO2 bottle and it works really well.
Mosquito catches have really increased.
I hope for a mosquito-free summer.
Effective with CO2 only. Please note: do not hesitate to move the device to a different location. We had a very small number of mosquitoes in the net even with CO2, so we moved it and within a short time, many mosquitoes had been caught.
Thanks to our own laboratory and significant investments in research and development, we have developed the Biogents Aero Trap Plus – a mosquito trap with attractants that deliver unparalleled and scientifically proven results.
Sustainability has been a core value at Biogents since the start. Our innovative mosquito machine is made from 95% recycled plastic to minimize environmental impact without compromising on efficiency.
We take a long-term approach with care for nature. Biogents Aero Trap Plus is a non-toxic outdoor mosquito trap that is free from insecticides and only captures mosquitoes, not beneficial insects like bees or butterflies.
We have developed solutions that fit all gardens. By offering effective outdoor mosquito protection, we help both private individuals and professionals protect their areas from mosquito infestations in a safe way.
The Biogents AERO TRAP PLUS is used outdoors to capture mosquitoes that want to bite you.
The trap is highly effective thanks to a combination of airflows and two attractants: an insecticide-free attractant, Biogents Sweetscent, which is scientifically proven to mimic the human scent that mosquitoes love. Using the control unit, the trap can be connected to a CO2 cylinder (not included) to mimic human breath, which serves as the second attractant.
Mosquitoes are irresistibly drawn to the trap and are “sucked” into the catch bag, where they dehydrate.
To use the Biogents AERO TRAP PLUS and the CO2 Control Set, you need to download the MyBiogents app. It is available for both iOS and Android. You can easily register all your devices to schedule CO2 releases based on the types of mosquitoes in your garden, set reminders so you never forget when to replace the attractant, and access helpful tips and videos.
Biogents is a mosquito trap brand founded by Dr. Martin Geier and Dr. Andreas Rose, mosquito experts whose research is backed by scientifically proven methods and data. A comparative study conducted in September 2024 by an independent laboratory concluded that the Biogents CO2 trap captures 3 to 4 times more mosquitoes than its main competitors. This research has resulted in patented designs, characteristic airflow, and the Sweetscent attractant.
Biogents Aero Trap Plus is designed to be an effective outdoor mosquito trap covering areas up to 700 m², making it ideal for gardens and patios.
Yes, by combining a patented scent with carbon dioxide (CO2), this mosquito trap mimics a human so effectively that it attracts all commonly occurring mosquito species.
You will notice an immediate effect when the trap starts catching active mosquitoes. After approximately two weeks of continuous operation, the mosquito life cycle is broken, leading to a drastic reduction in the population as fewer new eggs are laid. Results may vary depending on local weather conditions and temperature.
In a warm (preferably humid) and shady area near any vegetation as this is where mosquitoes rest during the day.
The mosquito trap should be protected from the wind and sun, as mosquitoes are less active in these climatic conditions.
Place the mosquito trap more than 5 meters from your terrace to avoid mosquitoes entering your personal space.
The product should be placed on the ground, as mosquitoes tend to fly low. Biogents AERO TRAP PLUS is also water resistant.
By mimicking human breath (in addition to the attractant that mimics human scent), carbon dioxide makes the trap even more attractive to all mosquito species and can increase the capture rate by up to five times.
The Biogents AERO TRAP is compatible with all CO2 cylinders. We typically recommend a 5 kg or 10 kg CO2 cylinder for long-lasting use in your garden, but you can also use a 425 g CO2 cylinder (screw-thread only), which is easily found in grocery stores and other retailers such as Clas Ohlson, Elgiganten, Power, Rusta, ÖoB, and others.
Depending on the programmed CO2 release intervals in your MyBiogents app, a 10 kg cylinder can last up to 2 months, while a 425 g cylinder is more practical for temporary boosts—for example, during weekends—lasting up to 3 days.
If you choose 425 g CO2 cylinders, you can easily purchase them at any grocery store in Sweden (as well as other major retailers). Don’t forget that only the screw-thread model is compatible with the Biogents AERO TRAP.
Larger cylinders are harder to find, although some local stores may carry them.
For the best experience, we’ve found the perfect partner to have your large (and small!) CO2 cylinders delivered directly to your door: Watertrade.
On the Watertrade website, you can easily purchase:
425g CO2 cylinder (screw-thread) : depending on the programmed CO2 release intervals, the cylinder can last approximately 2–3 days. We recommend starting with a 4-pack of 425 g cylinders to try out the solution.
2kg Co2 cylinder : Depending on the programmed time intervals for CO2 release, the cylinder can last for approximately 6 days. We recommend starting with a 2-pack. As soon as the first cylinder is empty, you can easily replace it and keep your trap running 24/7 as recommended. This gives you plenty of time to order a refill before the second cylinder runs out.
3.75 kg CO2 cylinder: Depending on the programmed time intervals for CO2 release, the cylinder can last for approximately 10 days. We recommend starting with a 2-pack. As soon as the first cylinder is empty, you can easily replace it and keep your trap running 24/7 as recommended. This gives you plenty of time to order a refill before the second cylinder runs out.

The amount of CO2 released per day is equivalent to the amount a small child exhales in a day. CO2 is colorless, tasteless, non-flammable, and has a very faint acidic odor. It is recycled from industrial production units, so its use as a mosquito attractant does not contribute to additional emissions of harmful CO2 to the planet; instead, it is simply a delayed release of recycled CO2 (industrial waste).
Carbon dioxide must always be handled safely, but if used strictly outdoors according to the recommendations, there should be no risk to you or the environment.
A CO2 cylinder should always be placed vertically, ensuring that it cannot fall. Please refer to your supplier’s instructions.
It is best to install the trap as early in the season as possible. The trap should be activated as soon as the average temperature exceeds 15°C, typically in the spring (from March to November, depending on the region). The goal is to catch mosquitoes before they have a chance to breed. You can keep the mosquito population as low as possible by capturing them as early in the season as possible.
Placement is crucial for the trap’s effectiveness! The best location to set up the Biogents Aero Trap Plus is in a shady, humid spot sheltered from wind and sun. Place the trap on the ground near vegetation, where mosquitoes tend to rest and breed. To find the optimal spot and achieve the highest capture rate, try different locations—just a few meters can make a significant difference.
Founded in 2002 by Dr. Martin Geier and Dr. Andreas Rose—two passionate friends driven by the conviction that solving the mosquito problem requires effective, sustainable solutions backed by scientifically proven methods and data. They founded Biogents to offer the best mosquito trap on the market: a solution that is both effective and environmentally friendly.
Soneva, a luxury island resort in the Maldives, faced a significant mosquito problem for many years. After more than two decades of using insecticides, the mosquito populations had become resistant to the method.

Many people looking for an effective mosquito repellent have already tried simpler methods without success. The difference between a regular mosquito repellent and an advanced mosquito trap lies in the technology: by imitating human breath and scent, we attract mosquitoes long before they have time to disturb your summer evening. This product differs from other mosquito repellents such as mosquito patches, mosquito sprays, mosquito coils and zappers as this product provides a long-lasting effect over a large area of land and is free of chemicals.
When choosing an outdoor mosquito trap, several factors determine the result:
To achieve a 95% reduction in mosquito populations, similar to our results in the Maldives, timing is key. Activate your outdoor mosquito repellent as soon as the temperature reaches 15°C to catch the first mosquitoes before they have time to breed.
