Problems Caused by Flies that Bite
In addition to the pain caused by bites, flies can trigger allergies for a number of people. Select species spread diseases to humans as well. Mosquitoes, for example, can transmit the West Nile and Zika viruses, while deer flies carry tularemia.
Even more types of flies that bite can attack livestock. In addition to spreading illnesses to the animals, fly swarms often affect the health of cattle or horses by causing constant agitation.
Getting Rid of Biting Flies
The best way to control biting flies is to remove the pests’ optimal breeding conditions. Mosquitoes need water to lay eggs, so emptying containers and other items around the yard after rainfall will curb their numbers. Other types of flies that bite may breed in rotting organic material, so prompt trash removal and cleaning of moist organic matter can help.
To deal with flies that bite, homeowners should contact Orkin. Skilled Pros can identify biting flies and provide safe, reliable fly control.
