Are mosquitoes attracted to UV light? This PF thread isn't very clear on whether it does or not- some of it suggests that it does... So, I looked it up and found this article on Wikipedia:
The American Mosquito Control association also states:Mosquitoes are attracted to carbon dioxide and water vapor in the breath of mammals, not ultraviolet light. However, there are now bug zappers that emit carbon dioxide or use an external bait, such as octenol, to better attract biting insects into the light.
Is the information that PF supplies to visitors within said thread correct or incorrect? Or is Wikipedia and the AMCA incorrect? I feel bugged about the contradiction right now.Bug zappers do indeed kill some mosquitoes. However, the only two controlled studies conducted to date by independent investigators at the University of Notre Dame showed that mosquitoes comprised merely 4.1% and 6.4% respectively of the daily catch over an entire season. Even more important was the finding in both studies that there was no significant difference in the number of mosquitoes found in yards with or without bug zappers. What is particularly disconcerting, however, is the number of non-pest insects that comprise the vast majority of trap catch.
