Containers or debris that hold even small amounts of water provide good sites for mosquitoes to reproduce in very large numbers. Rid your property of as many of these items as possible and encourage your neighbors to do the same. Clean gutters. Repair leaky outdoor faucets and irrigation systems. Clean and add fresh water to bird baths, pet bowls and flower pot saucers at least twice weekly. Please visit our Vector Control for more information on controlling mosquito populations.
