Guide to the Fleas in Your Basement

We all know that fleas prefer to dwell in your cozy furniture, rugs, and clothes. They can survive and get transmitted inside the pet’s fur.

While fleas may not be the main admirers of concrete, they can survive on the furniture you have there. Moreover, fleas may truly appreciate the darkness, damp air, and warmth they get hiding in the clutter.

What attracts fleas in the basement?

Let’s start from the very beginning. First, you should find out how fleas got into your basement, so you can prevent them from getting back in the future. While it seems like the basement is the most secure hiding place from fleas, these nasty creatures can use it as their spot. Tons of clutter gathered by generations are their safe haven. They also appreciate the warmth and lack of threads from outside.
Fleas may use the following ways to get into the basement:

  • They can ride your pet, hiding in the fur. If your dog often visits the basement, you should restrict its access there;
  • Opossums, squirrels, raccoons, rats, mice, and other pests who made their way to your basement can be a taxi for fleas;
  • Old furniture, clothing, and bedding that you keep in the boxes in the basement. These things can already have fleas inside.

Fleas can hide in cracks inside the furniture in the basement. Once they notice you turn on the light and move towards them, they will quickly disappear. You may start your investigation there if you keep old carpets and couches.

Even if there is nothing of such kind, fleas can build their home inside the wooden floor or concrete walls and floor. Yet, they still need a host to lay the eggs. Thus, it’s crucial not to let your pets go near the basement. You don’t want your dog or cat to be the meal for fleas which will also lay their eggs on their skin and fur.

Fleas in basement infestation signs

Before buying flea stuff for house, ensure these creatures are in your home. The bites you see can belong to a wide range of insects, including mosquitoes, bed bugs, and spiders. You have to find out how to spot them. The basics you need to pay attention to:

  • Your pet is constantly scratching. You may notice small wounds and signs of bites if you look closely at your pet’s skin. Fleas can still be there, hiding in the fur of your animal, feeding on their blood;
  • You have signs of bites on your legs, below the knees. If you don’t have pets in your house, fleas can get bolder and feed on you;
  • You notice fleas jumping in the basement;
  • You notice small white eggs lying in the old furniture;
  • You notice fleas’ feces in the basement. They are tiny, black, or red spots.
