How to control mosquitoes – what doesn’t work for controlling mosquitoes
Despite what your friends tell you, some popular mosquito control methods have no significant impact on keeping mosquitoes in check. According to Wayne J. Crans, Associate Research Professor in Entomology at Rutgers University, these often-touted mosquito solutions are not worth your time or money.
Bug zappers. Though the satisfying sizzle you hear from this modern day insect torture device will convince you it’s working, don’t expect much relief from backyard mosquitoes. According to Crans, biting insects (including mosquitoes) generally make up less than 1% of the bugs zapped in these popular devices. Many beneficial insects, on the other hand, do get electrocuted.
Citrosa plants. While citronella oil does have proven mosquito-repellent properties, the genetically-modified plants sold for this purpose do not. In tests by researchers, the test subjects bitten as often while surrounded by the Citrosa plants as without them. In fact, mosquitoes were observed landing on the leaves of Citrosa plants during the study.
Bats and/or purple martins. While both bats and the colonial purple martins will consume mosquitoes, the offending insects make up a small percentage of their natural diet. Assertions about these insectivores being effective mosquito controls grew out of misrepresented and misinterpreted data from unrelated studies. While providing habitat for bats and purple martins has its value, don’t do it if only to reduce your mosquito populations.
Electronic devices that transmit sounds to mimic male mosquitoes or dragonflies do not work. Crans goes so far as to suggest “the claims made by distributors border on fraud.” Enough said.
