What Attracts Mosquitoes to a Property?

A sudden, itchy insect bite on a warm summer evening often leads people to wonder what attracts mosquitoes. There are a number of factors that draw the pests to humans, yards, and buildings.

Are Mosquitoes Attracted to Light?

UV light traps and bug zappers work well against flies and moths. However, these traps only attract mosquitoes that overwinter as adults in early spring. Most biting insects, including female mosquitoes, aren’t attracted to lights in the UV wavelength.

What Attracts Mosquitoes to Humans?

Most of all, carbon dioxide attracts mosquitoes to people. Females have receptors that sense this gas when humans or animals exhale. Other attractants also help mosquitoes detect humans, including:

  • Sweat and body odor – Mosquitoes are attracted to the lactic acid that muscles release during exercise as well as other natural chemicals.
  • Body heat – Hiking or running brings blood closer to the skin’s surface, which makes people easy targets for the insects.
  • Movement – As visual hunters, mosquitoes look for anything on the move around them.


While some of these factors are hard to combat, home and business owners can take steps to avoid attracting mosquitoes. Using repellent sprays and wearing long-sleeved shirts with pants is a good start to defend against bites.
