Fight the Bite Fight the Bite Colorado is a public information campaign sponsored by the Colorado's state and local health departments. If mosquitoes are still flying there is still a danger from West Nile virus. Infected mosquitoes spread West Nile virus that can cause serious, life-altering, and even fatal disease. Keep using insect repellent, wear long sleeves and long pants and dump out standing water in the yard where mosquitoes can lay their eggs.
It's A Fact
All mosquitoes need water in which to pass their early life states. Adult flying mosquitoes frequently rest in grass, shrubbery, or other foliage, but they never develop there.
Some mosquitoes lay their eggs in standing water where they hatch in a day or two. Other mosquitoes lay their eggs in old tires, tin cans, or other water-holding containers in which they may remain unhatched for weeks or months until they are covered with water. With both types of mosquitoes, the "wigglers" or larvae grow quickly and turn into "tumblers" or pupae. Soon the skin of the tumbler splits open and out climbs another hungry adult mosquito.
