Fly eggs

Natural Habitat

Moist, organic environments including decaying plant matter, carrion, garbage, or damp areas in homes.

Diet & Feeding

Eggs do not eat. Upon hatching, the larvae (maggots) consume organic matter, such as rotting food, waste, or animal tissue.

Behavior Patterns

Female flies lay eggs in clusters (batches of 75 to 150) on suitable food sources. Eggs typically hatch into larvae within 8 to 24 hours in warm conditions.

Risks & Benefits

Risks: Potential for food contamination and spread of diseases/bacteria like Salmonella or E. coli if located near food preparation areas. Benefits: Larvae help decompose organic waste in the ecosystem.
