Do I Have Fleas or Bedbugs In My House?

If you have a pest problem in your house, the first thing you need to know is the exact pest you’re dealing with. If you don’t know which pest has infested your property, you might not use the right treatment. Meanwhile, the infestation grows out of control. 

It can be hard to identify which pest is causing a problem when there are two similar culprits. This is definitely the case with fleas and bed bugs. 

Do I Have Fleas or Bed Bugs in My House?

Both fleas and bed bugs feed on the blood of an animal or human host. Their tiny size means they can be hard to spot and they’ll often enter your home in similar ways. Fleas and bed bugs get in on:


Luggage/gym bags/handbags



Second-hand items, especially furniture. 

Telling these pests apart can be a tricky task, however, there are some key differences. 

Fleas or Bed Bugs: How are they Different?

They look different

While both pests are reddish-brown in colour, they have different shaped bodies. Bed bugs have a flat, oval shape, while fleas have long, narrow bodies. 

Their preferred hosts are different

One way to determine whether you are dealing with fleas or bed bugs is by looking at their preferred host. Bed bugs like to feed on human blood, so you’ll always find them where there are a lot of people. This is one of the main reasons why you’ll find bed bugs in populated places like London. Fleas, on the other hand, prefer to feed on animals but may feed on human hosts if there’s no other option. 

It’s worth mentioning that you probably won’t be able to work out if you’ve got fleas or bed bugs in your house from looking at bites alone. Every human or animal’s skin will react differently to bites and the bites won’t appear the same. 

Fleas and bed bugs have different methods of travel

This is one of the biggest differences between fleas and bed bugs. Bed bugs crawl and are unable to fly or jump. Fleas can jump from an infested item to a person or animal, or from one host to another.
