Backyard tiger mosquito control

BG-Mosquitaire CO2 against all mosquito species shows highest efficacy in mosquito control

Biogents’ Mosquitaire CO2 (BG-Mosquitaire CO2) trap is an excellent and eco-friendly tool to control all mosquito species and other flying bloodfeeding insects. The sturdy plastic trap is designed to be placed in your garden and has been tried and tested worldwide. Place the mosquito trap close to the mosquito resting areas and breeding places of the mosquitoes. In this way the mosquito trap will catch the mosquitoes before they reach the patio and annoy you.

Patented technology

The mosquito trap uses the same patented capture technology of all Biogents traps with the additional use of pure carbon dioxide (CO2) which is an attractive key element of human respiration and the most important attractant for blood-feeding insects. CO2 widens the spectrum of the collected species and their catch rates (including the tiger mosquitoes). Read more about why to upgrade the trap with CO2 >
To the mosquito, the trap looks just like a human being.

No trap from other manufacturers offers a comparable combination of

  • highest capture rates – scientifically proven
  • specificity does not damage beneficial insects like butterflies, bees, or ladybugs
  • and eco friendliness – uses no insecticides

If the traps are correctly positioned and run continuously throughout the season, they will effectively decrease the mosquito population, and you can enjoy your patio again.

The placement of the mosquito trap is an important factor to ensure high catch rates.
Therefore, it is best to test different locations!

Positioning of Biogents mosquito traps on shady, moist places in the garden
  • application outdoors
  • placement in shady, wind-protected moist places, near breeding sites of mosquitoes


For efficient and sustainable mosquito control it is necessary to

  • continuously operate the trap (24 hours for a number of weeks)
  • applicate the trap early in the season

If the traps are correctly positioned and run continuously throughout the season, they will effectively decrease the mosquito population, and you can enjoy your patio again.

CO2 Emission of the BG-Mosquitaire CO2 mosquito trap

Carbon dioxide (CO2) is the most important attractant for blood-feeding insects and necessary to attract a wide range of mosquito species.
For the BG-Mosquitaire Biogents suggests as CO2 source carbon dioxide from 10 kg bottles which are also used in pubs and restaurants. Such a bottle lasts for three to seven weeks, depending on the flow rate used.Under most circumstances, we recommend a flow rate of 0.5 kg per day. The flow rates correspond to the rate that is released by a small child.

Carbon dioxide bottles are available at gas stores and gastronomy suppliers.

Placement of traps diminishes the local mosquito population when

  • correctly positioned
  • continuously operated (24 hours a day throughout the mosquito season)
  • operation begins early in the season

Examples of areas that can be protected by traps

  • backyards and gardens
  • outdoor cafés and restaurants
  • hotel outdoor areas
  • campgrounds
  • facilities for outdoor sports and recreation

Recommendation from Tom Rodney, Greenville, North Carolina (bought BG-GATs and the BG-Mosquitaire with CO2):
“I would recommend the BG – Mosquitaire CO2 trap because it works and is relatively inexpensive and safer to operate and is used by local governments across the U.S.A. and the world. I do believe in Biogents products and wish you continued success in the U.S.A.”
