Biogents CO2 CONTROL SET

What is the function of the Biogents CO2 CONTROL SET set?

Biogents CO2 CONTROL SET not only connects the trap to a CO2 bottle (the CO2 bottle must be sourced separately sourced separately). The CO2 CONTROL SETalso helps to disperse the optimal dose of CO2 to imitate a human. In addition, the release rate can be adjusted to the local and seasonal mosquito situation.


MyBiogents APP

The MyBiogents APP allows you to adjust the CO2 emission time frames. You can also receive notifications when the CO2 and attractant need to be replaced and easily access all our Biogents advice and videos.

How long does a gas bottle last?

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

  • what size you use and
  • which time frames you have set in the MyBiogents APP for the CO2 release

Optimal and low release rate of CO2

Biogents CO2 CONTROL SET adjusts the amount of CO2 released to the amount that is optimal to attract mosquitoes. Biogents recommends a daily release of 0.5 kg. This is about the amount a small child exhales daily. For comparison, an adult human exhales about 1000 grams of CO2 daily, and an average car produces about 1500 grams of CO2 per 10 kilometers.
