Getting flea bites with no pets in the home usually means wildlife. Rodents, raccoons, or feral animals nesting under the house or in the crawl space bring fleas that then move indoors — so the fix involves both the fleas and the animal source.
What’s most likely going on
Fleas do not need a pet — any warm-blooded host will do. Wildlife nesting in a crawl space or under a deck seeds the environment with flea eggs and larvae that develop and bite people even in a pet-free home.
What it means for your home
Bites cause itching and allergic reactions, and because most of the population is immature and hidden in flooring and crawl spaces, the problem persists until both the fleas and the wildlife access are addressed.
What to do next
We treat the home across all flea life stages, check the crawl space and exterior for the animal source, and seal the access that let wildlife in. You can read more in our Pest Library entry on fleas, or head straight to our Flea Control service.

Frequently asked questions
How do I have fleas without a pet?
Wildlife — rodents, raccoons, or strays — nesting under or in the home brings fleas that then bite people indoors. The animal source has to be addressed too.
Why do they keep coming back after I treat?
Most of the population is eggs and larvae in flooring and crawl spaces. Without treating the whole environment and the source, they re-emerge.
