Where Do House Flies Lay Eggs?

If you have a house fly infestation, it’s imperative to clean up the area where these critters live and lay eggs. One of the most common places for flies to lay eggs is on leftover food, especially if it’s been sitting around for a while. These messes provide a large amount of food and nutrients for the flies to lay their eggs. Larger messes can also foster multiple generations of flies, leading to an overall infestation of your home.

While flies normally breed outdoors, they will occasionally fly indoors to lay their eggs. These creatures will often enter your home through an open door or window and will then head to the most moist, dirty place in your home. This is usually your kitchen garbage bin or a dirty drain. Flies prefer areas with warm, moist material because this provides food for the larvae and maggots. When these larvae hatch, they’ll look for rotting food and other animals to feed on.

The larvae of the house fly are pale-whitish and three to nine mm long. They feed at the egg-laying site for three to five days and then move to a dark area to pupate. During this time, they develop wings and legs and become fully grown house flies. Once matured, these insects live for fifteen to twenty-five days.
