Where do fleas lay eggs in the house? - briefly
Flea eggs are deposited in carpet fibers, pet bedding, upholstery, and cracks or crevices in flooring and furniture where adult fleas reside. These locations supply the warmth and humidity required for egg development.
Where do fleas lay eggs in the house? - in detail
Fleas deposit their eggs primarily in areas where adult females can remain undisturbed and where environmental conditions support embryonic development. Typical indoor locations include:
- Carpet fibers and the backing material, especially in high‑traffic zones.
- Pet bedding, blankets, and any fabric that regularly contacts animals.
- Upholstered furniture seams and cushions, where moisture can accumulate.
- Cracks, crevices, and under floorboards, providing protection from disturbance.
- Baseboard and wall voids, particularly in humid rooms such as bathrooms or kitchens.
Eggs are microscopic, non‑motile, and adhere to fibers or surfaces. They require relative humidity of 70 %–80 % and temperatures between 20 °C and 30 °C to develop. In dry conditions, eggs may become dormant, extending the life cycle.
After hatching, larvae feed on adult flea feces, which contain blood residues. Consequently, areas with frequent pet activity generate the necessary food source, reinforcing the preferred oviposition sites listed above. Regular vacuuming, washing of pet linens, and maintaining low indoor humidity reduce egg survival and interrupt the flea life cycle.
