Does My House Have Fleas?

Sometimes you see fleas and you know that your house has fleas. Other times it may not be as obvious. I’ll go over 9 ways to tell if your house has fleas along with several other things you MUST know when you have a flea infestation in your house.

There are 3 things to look out for in order to tell if your house has fleas.

1. Scratching (either humans or pets)

It’s no secret that fleas bite. And if you or your pets have flea bites then scratching is probably going to be one of your first indicators that your house and/or pets are infested with fleas.

In humans, fleas like to bite your ankles and lower legs. If you are getting flea bites in bed they may also show up on your wrists.

In pets fleas like to bite around the neck, the back of the head, and the tail area.

You are looking for abnormal scratching here. Animals do scratch and even human skin gets itchy from time to time. You want to look for scratching that goes above and beyond the usual.

2. Red skin and visible flea bites

I know that this one seems obvious, but flea bites are a good indicator that you have fleas in your house. Fleas like to bite at night and they are super stealthy so you may not actually ever see a flea but still get flea bites on yourself or your pet.

Flea bites show up as small red, itchy welts on both human and animal skin.

3. Wear white socks

This is a weird one, but it works. If you wear white socks and walk around your house, then you can stir up the fleas and see them as they hop on your socks.

Wearing longer socks will help you not get bit.

You should remove the socks carefully after you’ve shuffled around your house for at least 10 minutes and inspect them to see if you have any fleas.

Bonus tip: Fleas also leave flea dirt behind. This is their poo, which is gross but you will often see the flea dirt before the fleas. You want to look for small black or red-brown specks that sort of look like dust. If you find this you might have fleas!

Where In the House Do Fleas Live?

Fleas can live in LOTS of places in your house, but they love carpets, bedding, and crevices. Anyplace where they can hide and then jump onto you or your pets for a meal works for fleas.

In addition flea eggs are tiny, hard to see, and will fall off of a flea infested animal just about anywhere. That means that fleas can hatch even after you’ve taken care of your adult flea infestation.
