Mosquitoes require only about a bottle cap full of water, or about half an inch of water to breed. Because of this, it is important to walk your property and address any sources of standing water in order to prevent an influx of pests during storms and after storms. While this standing water can be found in obvious places it can also be found in birdbaths, clogged gutters, grill covers, flowerpots, and garbage cans and lids. By taking the time to drain and empty these water receptacles you can prevent the development of a mosquito population in your own backyard.
