The Repellency Evaluation of our natural mosquito candles performed in Florida in 2011 collected 20 species of mosquitoes. Some species of these collected mosquitoes will be the same in your region of the country, but you can never say 100% without looking up your district’s mosquito records. For example, while there are species differences between where the scientific testing of our natural mosquito repellent candle formula occurred and in Suffolk County, NY, at least 75% of the species collected in the control trap in the test area in Florida are also found in Suffolk County. With that said, as a general rule, mosquito repellents are not typically species specific. Spatial repellents, such as candles, work by modifying the behavior of host seeking mosquitoes.
