From Outside

Most fleas come from outside the house. These bugs love shady, cool and moist places like bushes, trees, areas near ponds and underneath the porch where animals usually hide.

Fleas don’t originate from these places though. They are brought there by pets, strays or wild animals. What usually happens is that animals that are already infested drop flea eggs everywhere they go. And some of these eggs end up in suitable environments outside where they can grow into adult fleas and multiply.

From Other Pets

Fleas are permanent parasites. They prefer to stay in one host. In fact, it’s actually pretty rare for them to jump from one host to another.

According to Flea Science, cats and dogs hardly get fleas that jump off from other animals. A study on adult cat fleas even proved that only 5% of these bugs transfer between hosts separated by cages, and only 7.5% of them transfer when animals live together.

The study also proved that pets scratching themselves don’t distribute fleas to other pets or even to humans. That’s because what mostly spreads these insects are their eggs falling from hair strands, landing into carpets and rugs among other places.

However, as long as the chances don’t fall to zero, your dog or your cat could still get fleas from other pets. So as tragic as it may sound, every time your pet takes a walk around the neighborhood or every time you bring over an animal into your house, you’re exposing your home to fleas.

From Wild Animals

Wild animals

A wild animal that dies somewhere near your house can cause its fleas to transfer into your property or into your pet while it roams outside.

While fleas like to stay in one host, they do leave an animal when it dies. As a result, nearby suitable environments and hosts can take in those vacating fleas.

For Flea Science, the most common animals that carry these fleas are feral dogs and cats, skunks, bobcats, raccoons, rabbits, opossums and foxes.

From an Already Infested Home

There are houses or apartments that seem to just have an infestation from out of nowhere. Without pets for the fleas to be attracted to, the next possible explanation could be that that particular living space already has fleas to begin with.

Fleas can survive for 133 days without a host. So it’s not surprising that they can live inside an empty house for a fair amount of time, patiently waiting for hosts to come. These bugs can stay in a non-active stage until vibrations and carbon dioxide emission from hosts liven them up.

And now that you know where fleas come from, you can take the necessary steps to keep these bugs from invading your home further. There are plenty of treatments available on the market today, but you can also try natural and inexpensive ones here.
