If you want to get rid of mosquitoes, attract bats to your property by installing a bat house. Purple Martins like their house to be in a very open spot, at least 50-100 feet from human housing. The Martin house should be 10-20 feet off the ground. Keep it open until at least the end of June. If Martins nested last year, open your house when the first Martins perch on the roof.
Martins seem to be attracted to white houses.
This color will also keep nestlings cooler. If Sparrows or Starlings start to build in the Martin House, lower the house and remove the nest material. You may need to do this several times. Stokes Purple Martin Book Donald and Lillian Stokes give bird lovers all the information they need to start and maintain a backyard purple martin habitat. The book is illustrated throughout with over a hundred color photographs.
