Where Fly Eggs Are Found

Where flies lay eggs depends on the species, but in general, these insects will lay eggs in moist, dark areas. These areas will include trash, rotting food, and manure. They may also be in feces and litter boxes. The larvae emerge from these eggs and feed off the trash.

During the day, house flies congregate indoors. They also hang around plants, fence wires, garbage cans, and other areas of the ground. These flies usually rest five to 15 feet off the floor and close to food sources. During colder weather, these flies can be found in attics and basements.

Female house flies lay their eggs in warm, moist materials. They develop into fully-grown adult house flies within 15 to 25 days. The larvae feed on animal manure, decaying vegetable matter, and organic matter on the ground. The female house fly can lay up to 350 eggs in her lifetime. The eggs are 1.2 millimeters long and hatch quickly in warm weather.

Fly eggs can also be found in leftover food. Leftover food can be a fly magnet, so don’t leave food out in your fridge for extended periods. Food crumbs, spilled grease, and pet waste are all places where flies lay eggs. The eggs from these materials can grow to multiple generations and result in a large infestation.
