Mosquitoes are the worst part of summer. They can ruin a great day. There is nothing more irritating. The best way to deal with mosquitoes is to reduce them in your yard. Mosquitoes breed in stagnant water. Get rid of puddles or anything that holds water. Regularly change out the water in the bird bath. Get a bat house. Bats can eat hundreds of mosquitoes an hour. You can buy mosquito eating fish for your pond. Cover anything that can hold water. Keep your grass cut.
