Why upgrade to carbon dioxide (CO2)
If you live in a suburban or urban setting near low lying areas that are subject to flooding, and you are mainly bothered by mosquitoes in the evening, the cause of your problem is probably floodwater mosquitoes, and not tiger mosquitoes.
Floodwater species develop in early spring in woodland snowmelt pools and during the summer in woodland and open field rainwater pools or drainage ditches that hold water for a few weeks to months.
A number of floodwater breeding species occur throughout the US and can cause serious annoyance around dusk. Some of the more common species are: the common floodwater mosquito (Aedes vexans), the woodland pool mosquito (Aedes canadensis), the striped floodwater mosquito (Aedes trivattatus), the dark rice-field mosquito (Psorophora columbiae), the common white footed mosquito (Psorophora ferox), the gallinipper (Psorophora ciliata), the common malaria mosquito (Anopheles quadrimaculatus), the southern house mosquito (Culex quinquefasciatus), the unbanded saltmarsh mosquito (Culex salinarius), the winter marsh mosquito (Culiseta inornata) and other species that do not have common names (Aedes atlanticus, Aedes infirmatus, or Psorophora ferox).
Adding of CO2 to the BG-Mosquitaire trap
The BG-Mosquitare with BG-Sweetscent lure is very effective in collecting the tiger mosquito (Aedes albopictus) and the dengue or yellow fever mosquito (Aedes aegypti). Carbon dioxide is a scientifically proven attractant that is routinely used by mosquito control professionals to enhance their mosquito surveillance efforts. So by adding CO2 as a supplemental attractant you can increase the variety of species and total number of mosquitoes that will be collected by the trap. In other words: Using CO2 allows you to target certain pest species (floodwater mosquitoes) that would otherwise be under-represented in your trap catch.
