Collier Pest Control is Southwest Florida’s Pest Authority, including the common House Fly. The House Fly is oneof the most common of all insects. It is worldwide in distribution and is a pest in homes, barns, poultry houses, food processing plants, dairies, and recreation areas. The House Fly has a tremendous breeding potential all year in Florida and can produce a generation in less than 2 weeks. House Fly eggs can be laid in almost any type of warm organic material, such as fermenting vegetation, manure, or garbage. House Fly eggs hatch within 24 hours into tiny larva called maggots. In 3 to 6 days these maggots migrate to drier areas and cocoon themselves just like a butterfly. A House Fly can complete its life cycle, (egg, larva, pupa, and adult) in Florida in 6 to 10 days, living a life span of about 30 days.
