The top three types of mosquitoes in the USA are Anopheles, Culex, and Aedes aegypti, all of which carry diseases such as West Nile virus and Equine Encephalitis.
Mosquitoes are attracted to humans and other animals, and some people remain targets for no apparent reason. They can detect us from over 160 feet away, so it is important to stay vigilant and wear dull, neutral clothing.
DEET is one of the most effective insecticides, but it can cause skin irritation and can damage fabrics. Picaridin and IR-3535 are less toxic and have been used for decades in Europe.
