Mosquito Reduction – Mosquito Myths

The Truth About Mosquitoes!

Because they are ubiquitous, there are many misconceptions about mosquitoes. Some of the more common ones include:

  • Bug zappers are effective against mosquitoes
    • Bug zappers DO NOT control mosquitoes and can reduce the populations of beneficial insects.
  • Electronic Repellents keep mosquitoes away
    • No they DO NOT; save your money.
  • Residential vegetation can produce mosquitoes
    • They may be resting in the vegetation, but standing water is required to “produce” mosquitoes.
  • Bats, Owls, and other birds can control mosquitoes
    • Although they may include mosquitoes in their diet, they do not consume enough mosquitoes to make an appreciable difference in their populations.
  • Some mosquitoes can be 2 inches long
    • They DO NOT get that big; it was probably a crane fly
  • Mosquitoes nest in vegetation
    • Mosquitoes DO NOT nest
  • Spraying for adults is the best method of mosquito control
    • Adulticiding is the least efficient method. Reducing mosquitoes before they become adults is preferable.
  • The Citrosa plant repells mosquitoes
    • Although Citrosa oil (citronella) has been used widely as a mosquito repellent, the undisturbed plant itself does not release these oils and is thus not effective as a repellent.
