The Dangers Of Housing Crawl Space Pests

Insects, rodents and other animals in your home are more than just a nuisance. Respect the risks and get serious about taking action to get rid of them, prevent them, and keep them at bay.

Once they move into your basement or crawl space, it’s only a matter of time before these critters will try to make their way into your home. Once they get into the rest of your house they will continue to do more damage and pose more risks.

The longer you wait, the more expensive this will get. This not only applies to treating pests and ridding your home of them, as well as repairing damage, but also the value of your property. If you try to refinance your house in Indianapolis, IN, or sell it, lenders will want to know the condition. Even if you find a willing buyer, they may not be able to get financing until you get the situation corrected and can prove it. Obviously, any potential buyers are going to want to pay a lot less for a home with crawl space rodents and other pest infestation or damage.

Health is a major concern too. The conditions that are conducive for attracting pests naturally present a variety of health concerns for humans too. These alone can be very serious or fatal.

Crawl space rodents alone and their droppings can transmit almost a dozen diseases to humans, according to the CDC.

These include:

  • Hantavirus
  •  Hemorrhagic fever
  • Meningitis
  • Lassa fever
  • Salmonella
  • Rat-bite fever
  • Leptospirosis

Types Of Pests & Rodents In Your Crawl Space

Rats, mice, and squirrels are some of the most common to try to make this part of your home their home. They breed fast once they are in. You may even get possums, skunks, and snakes.

Insects can be just as bad. These may include:

  • Dust mites
  • Cockroaches
  • Bed bugs
  • Termites
  • Flies
  • Gnats
  • Ants

All of these can be health hazards.

What Attracts These Pests To Your Crawl Space?

The most common reason these pests are attracted to your home is dampness. Damp crawl spaces are heaven for these insects and rodents.

This damp also causes toxic molds and can continue to deteriorate your home and cause major foundation issues, even if you don’t get pest infestations.

Crawl spaces are also commonly littered with junk, are dark, and offer lots of hiding space and food materials for insects like wood beams.

Cleaning & Securing Your Crawl Space

Step one to preventing or ridding your home of pests is to clean out your crawl space: Get all the junk out.

Then treat any signs of pest infestations. You may spot treat signs of previous infestations, or you may have to tent and fog your home in the case of termites. Poisons, chemicals, and traps, as well as professional pest services, can all play their part.

If you don’t want to have to live with these pests or risk the incredible damage and health risks they can bring into your home, start with cleaning your crawl space.

Do not underestimate just how bad these rodents and insects can be. Once you’ve cleaned and treated current infestations, work on prevention. The smartest solutions go beyond just chemicals to protecting the integrity and foundation of your home. Along with keeping out the critters, this can save your house from devaluing fast and the hefty costs of reviving the structure your home sits on.
