Add to that the fact that each female can lay 100-400 eggs and you can see why you can have so many mosquitos in a very short time. We can try to eliminate or reduce mosquitos in several ways, and combining methods is best. We need to reduce reproduction by eliminating breeding sites, reduce the adult population, and keep the remaining mosquitos away from us and our pets. One of the most important things to remember is that mosquitos need water to reproduce. No water, no reproduction.
Control then is based on removing standing water which can serve as a breeding site.
Pet water bowls Manmade pools and ponds We need to eliminate breeding sites such as old tires and discarded cans. We need to change the water at least weekly in birdbaths, dump out water accumulating in flower pots, and give fresh water to our pets. Tree holes can be filled with sand. Goldfish or minnows would love to eat the mosquito larvae and pupae in ponds. Adult mosquitos like to rest where it is cool, dark and damp, so keeping grass cut and weeds and brush under control may encourage mosquitos to find shelter elsewhere.
