The adult female fleas will lay their eggs in the protective covering of carpet fibers. Then the larvae will hatch and feed on blood droppings left behind by the female adults, along with organic debris. Eventually the larvae will spin cocoons that pick up debris, making them blend in well to carpeting. While carpets are the most common places to find baby fleas, there are are few other places that might be infested. They are:

  • Carpets
  • Rugs
  • Bedding
  • Pet bedding
  • Pet kennels
  • Clothes
  • Blankets
  • Dog & cat fur

In the backyard, the larvae will likely be found in places where your pet likes to rest. Other common outdoor locations are under boards, behind flower pots, and in dark areas. They like dark, moist, and shaded locations.
