Fleas originate from another infested animal. They easily spread between different animals and then make their way into your home when the pets come in for a visit or to sleep. Outside, fleas can typically be found in shady areas, near long grass or bushes, while they wait for a host to pass by.

Where do fleas come from in the first place?

The first fleas may come from the environment or from another infested animal. These tiny parasites can spread between cats, dogs and other pets as they establish themselves in your home. In the outdoors, adult fleas stay near long grass, bushes or other shelter as they wait for a host to pass by.

Where do fleas live in the house?

When the fleas reproduce, more fleas can infest your home. They tend to hide in bedding, furniture, and floor cracks. Fleas also like to stay on an animal's underbelly, so they can easily be transferred to your carpet when your pet lies down.
