Mosquitoes In Iowa

There are over 40 species of mosquitoes in Iowa alone. Only the female mosquitoes feed on blood. They can up to 10 days in ideal conditions.


Mosquito bites can cause skin reactions, secondary infections, and diseases/viruses.

Some diseases caused by mosquitoes are:

  • Encephalitis, which is brain inflammation
  • Lacross Encephalitis, caused by tree hole mosquitoes
  • West Nile Virus
    • Symptoms Of West Nile: Fever, Headache, Fatigue, Rash, Swollen lymph glands


The best way to prevent mosquito bites is to wear personal protective equipment like long sleeve shirts and long pants, use a personal repellent like DEET, stay inside during heavy mosquito activity (dusk and dawn), and avoid scented personal products.

Eggs from mosquitoes can be deposited in low lying areas where flooding occurs, and in permanent water like ponds, lakes, and standing water.

Controlling Mosquitoes


The best way to control mosquitoes is to limit their sources. Here are some ways to do this:

  1. Modify areas to eliminate standing water
  2. Eliminate or minimize vegetative growth
  3. Make sure windows have screens
  4. Replace bird bath water every few days
  5. Put larvacide in ponds


Another way to control mosquitoes is to put mosquito eating fish in areas that mosquitoes breed in. This must, however, be checked with the state conservation commission.


Black light electrocution traps are an effective method to control mosquito populations in enclosed areas.


Use of pesticides limits the amount of mosquito larvae and adults, depending on the chemical.
