Different attractants can be added to Biogents’ mosquito traps to increase their capture rates. Which kind of attractant depends mainly on the trap type and on the mosquito species which is desired to be captured and in which life cycle stadium the mosquito is:
A) Mosquitoes that search for a blood meal
Studies have shown that a mosquito recognizes and finds a human being from a relatively long distance by the human’s breath and skin scents. The mosquitoes fly against the wind direction towards the blood host.
Carbon dioxid (CO2)
The main component of breath is carbon dioxide. Carbon dioxide (also known as carbonic acid or CO2) is the most important attractant for the majority of blood-sucking insects, therefore also for mosquitoes.
CO2 can be added to following Biogents traps: BG-Mosquitaire, BG-Pro, BG-Sentinel
B) Mosquitoes that search for a place to lay their eggs
To attract mosquitoes that are searching for a place to lay their eggs, it is best to imitate a breeding site – and that is what the BG-GAT does. The attractivity of the BG-GAT can be enhanced by adding hay (for example 10 g of dry hay2) or other organic materials such as one leaf or 1 g of rabbit chow or alfalfa pellets per liter in the water of the BG-GAT bucket.
