Backyard tiger mosquito control

Biogents mimics human skin scents with the BG-Sweetscent

A hungry female mosquito (male mosquitoes don’t bite) recognizes and finds its human blood source from a relatively long distance by the breath and skin scents. The most important component of breath is carbon dioxide (CO2), and it is used by most mosquitoes as a major host-finding cue. In addition to carbon dioxide, there are also certain components of human skin scents that provide important information for the blood-seeking mosquito. The most important is lactic acid (also found in sourkraut, yogurt, or cheese).

An attractant for tiger mosquitoes

Asian tiger mosquitoes (Aedes albopictus) and dengue / yellow fever mosquitoes (Aedes aegypti) are very much adapted to the human environment. They especially target humans and do not rely on carbon dioxide as much as other, more generalist mosquito species. This is why they can be attracted sufficiently just by human skin odours.

The BG-Sweetscent is a pouch containing a proprietary and patented formulation based on lactic acid which mimics human skin scent. All components are in food grade quality.

Using the BG-Sweetscent in mosquito traps increases the traps’ attractiveness to Asian tiger mosquitoes and dengue / yellow fever mosquitoes.

The BG-Sweetscent is registered by the United States Environmental Protection Agency (EPA), registration number 87472-1, and is available throughout the US, including California.

Scientific basis

The BG-Sweetscent was developed through extensive laboratory and field testing. Numerous peer reviewed scientific articles have been published documenting the effectiveness of the attractant. Scientific studies show that using BG-Sweetscent in a variety of commercially available mosquito traps can increase catch rates of mosquitoes that transmit diseases like Dengue, Zika or Chikungunya by up to 4 fold. BG-Sweetscent is the first attractant targeting Aedes aegypti and Aedes albopictus that has been scientifically proven to work with many different traps.

The BG-Sweetscent


The BG-Sweetscent mimics human skin scent.  It is a pouch containing a proprietary formulation based on lactic acid. Combining the BG-Sweetscent with Biogents trap’s patented attractive technology of ‘heat convection’ and ‘light-and-dark-contrast’ increases catch rates.

The BG-Sweetscent is effective for up to two months.

The BG-Sweetscent can be used with the BG-Mosquitaire, BG-Home, or other mosquito traps that attract host-seeking mosquitoes. For the BG-GAT, a trap that catches mosquitoes that are looking for a place to lay their eggs, the BG-Sweetscent is not recommended.


Important: Do not open the sachet!
Example where to place the BG-Sweetscent sachet in the BG-Mosquitaire mosquito trap:



If you use the BG-Sweetscent with another mosquito trap, the BG-Sweetscent can be placed inside the trap, on top, or under the roof depending on what trap model is used.
