House Fly Problem
Although a common house fly problem may seem like a minor irritation upon initial identification, infestations can multiply exponentially within a brief period of time. Houseflies enter the home when a fertilized female fly locates an indoor source of trash or other decaying, organic material within which to lay her eggs. Females are capable of laying many eggs at one time.
Within 24 hours, eggs hatch into small, white larvae, also known as maggots. Maggots feed on the same decaying, organic matter within which they hatched. The sole purpose of the larval housefly is to store nutrients for the pupal stage of its life. After approximately four days, larvae develop small, hard, brown pupal cases in dry, dark locations.
It is difficult to address a house fly infestation because adults are fast moving and pupae are nearly impossible to locate. To avoid infestation, strict sanitary measures should be undertaken. If your home is already host to a house fly infestation, contact your local pest control professional to discuss methods of eradication.
