Leaf Piles

Wild animals and roaming pets drop flea eggs on your yard. And some of those eggs hatch and thrive in leaf piles.

According to Pet MD, fleas prefer leaf piles because they maintain a cool temperature; they provide shade from the sun, and they have enough moisture to support an entire population.

Outdoor Feeding and Sleeping Spots

We call this flea “hotspots”. These are areas outside of the house that gets the most visits from animals. These can be feeding spots for your pets, nesting places for wild animals or a cozy spot at the bottom of your porch.

Just like the leaf piles, these hotspots were once normal flea-free places until an infested animal drops flea eggs on it. The eggs then develop into adults that hop into another visiting animal that unknowingly drops off another batch of eggs. The cycle continues and only breaks if you treat the hotspot with flea products.

Carpets and Rugs

One of the best hiding places for fleas are just under our feet.

Carpets and rugs give these fleas a suitable environment to grow in. Your indoor pets drop the eggs this time. The eggs settle in the carpet/rug and eventually hatch into larvae. Organic materials, fallen flea feces and other debris in the carpet/rug feed the larvae to grow into adults.

Floor and Wall Cracks

Fleas can hide between floor cracks and wall cracks. These slim gaps provide just enough space and protection for fleas to hide in until they find their host.


Tiny seams in upholstery are actually big enough to temporarily house fleas. When disrupted, fleas can evacuate into the smallest crevices for shelter.



Oftentimes, flea bites are confused with bed bug bites. That’s because fleas can live on your bed too. The readily available meal every night makes the bed an ideal place to live in.

So if you suspect fleas, here’s a video from eHowPets that demonstrates how you can check your beddings for fleas.


Finally, the best place to look for fleas is on their hosts.

Unlike bed bugs, fleas like to stay on the hairy parts of their hosts. Cat fleas and dog fleas live in the fur of our pets while human fleas, a much less common species, reside in the hairier regions of the human body like our head, armpits and pubic areas.

Animal fleas can also stay in less conspicuous areas of the body like under the ears, in the armpits or between the toes of your pet’s paws.

So the next time you ask your exterminator, “Where do fleas hide?”, know that these insects can hide virtually anywhere. But at least through this article, you now know where to focus your flea treatments on.
