Will I notice a meaningful reduction in my local mosquito population?

 

Many people have anecdotally reported reduced mosquitos. Another controlled study documented that bats could significantly reduce egg laying success for mosquitoes. Recently, a paper published in the Journal of Mammalogy reported a new study from Wisconsin that documented widespread consumption, by little brown and big brown bats, of 15 species of mosquitoes, nine of which are known carriers of West Nile virus. These two species are the most frequent bat house users in the northern half of the U.S. and Canada.
