← CO2 overview

Biogents offers the outdoor trap BG-Mosquitaire in two variations:

The BG-Mosquitaire CO2 trap which includes a CO2 upgrade set (the CO2 bottle must be sourced separately) and the BG-Mosquitaire trap without CO2 set.

Carbon dioxide plays a subordinate role for a few mosquito species that have specialized in human beings. These mosquitoes recognize humans mostly by their skin odor.

Therefore, the Biogents traps with their visual skills in combination with the human scent imitation are still ideally suited for capturing these mosquito species without the addition of carbon
dioxide. This especially applies to tiger mosquitoes, but also to Southern house mosquitoes or a few malaria mosquitoes (Anopheles). Although the trap is sufficient for these mosquito species, the catch rates can be further increased by the addition of CO2.

Although the use of carbon dioxide can increase the capture rate significantly, traps can also be used without the addition of CO2 against these mosquito species.

By adding CO2 to your BG-Mosquitaire, you increase your catch rates and attract a wider variety of mosquito species. Especially if you are bothered by mosquitoes in the evenings or if you live near an area that is often flooded, it is most likely that you are not annoyed by tiger mosquitoes but house or floodwater mosquitoes. In this case, we recommend to upgrade your BG-Mosquitaire trap with the BG-Booster CO2. With the combination of BG-Sweetscent and CO2, you also multiply the catch rate of tiger mosquitoes. Therefore, an upgrade with CO2 can also be very useful when you are strongly bothered by tiger mosquitoes.

It is easy to add CO2 to your BG-Mosquitaire trap with the BG-Booster CO2 upgrade set which
includes a pressure regulator, emitter nozzle and CO2 pipe. The BG-Booster CO2 does not only connect our traps with a CO2 bottle (the CO2 bottle must be sourced separately). The BG-Booster helps disperse the optimum dose of CO2 to imitate a human being. Further, the release rate can be adjusted to the local and seasonal mosquito situation.

In the following video we show you the installation of the BG-Booster CO2 to your BG-Mosquitaire.

The gas bottles are not included in the contents. For our CO2 traps, we recommend using a 10 kg gas bottle. However, you could also use 5, 6, 10, or 20 kg if you prefer. These can be acquired or rented at drink retailers or bottle depots for a deposit. A door-to-door delivery service may also be possible in some locations. More info about possible CO2 sources in your region.

How often you need to change the gas bottle depends on:

• what size you use and

• which release rate of CO2 you use. Our CO2 traps give you the option of deciding between two flow rates: standard and high. This allows you to adapt the release of CO2 to the mosquito situation. If CO2 is released 24 hours with our recommended release rate of 0.5 kg/day, a 10kg CO2 tank will last about 20 days. Using a BG-CO2 Timer, you can reduce the CO2 release, then the tank will last about two months (60 days).

Biogents recommends using CO2 gas bottles as CO2 source. The CO2 in gas bottles is not explicitly produced to be bottled, rather, it is a recovered by-product from other industrial processes. Therefore, the use of CO2 from gas bottles as a mosquito attractant does not constitute an additional contribution of CO2 to the planet, but is only a delayed diffusion of CO2 as industrial waste. The main use of CO2 from gas bottles is in the production and distribution of carbonated drinks. CO2 is colorless, tasteless and non-flammable.
A CO2 bottle should always be placed upright and in such a way that it cannot fall over. Please refer to your supplier’s instructions.
