House centipedes are one of the most dreaded insects that homeowners have to deal with. They scuttle across floors and walls at lightning-fast speed, their numerous legs sending shivers down the spine of anyone who sees them. However, these bugs are not just a source of fear; they can also be an indication of underlying problems in your home. In this article, we will tell you everything you need to know about house centipedes and how to get rid of them for good!

The Basics of House Centipedes

House centipedes are arthropods with a distinctly creepy appearance. They have long, skinny bodies that are typically 1-1 1/2 inches long, and they are covered in hair-like strands that give them a distinctive look. These bugs have up to 15 pairs of legs, which they use to scamper across surfaces at lightning-fast speeds. House centipedes are often found in damp, humid areas of the home, such as basements, bathrooms, and kitchens. They feed on other insects, making them beneficial in small numbers, but they can quickly become a nuisance if they are allowed to thrive.

Signs You Have a House Centipede Problem

If you think you might have a house centipede problem, here are some signs to look out for:

  • You see centipedes crawling across floors or walls.
  • You find discarded skins or egg sacs.
  • You notice an increase in other insect populations, such as spiders or silverfish.
  • You find moist or damp areas in your home, such as areas with leaky pipes, that could be attracting centipedes.

How to Get Rid of House Centipedes

If you have a house centipede problem, don’t panic! There are several steps you can take to get rid of these creepy crawlies:

Step 1: Clean Your Home Thoroughly

Start by cleaning your home thoroughly. Sweep or vacuum up any crumbs or debris on the floor, and wipe down counters and surfaces with a damp cloth. Pay attention to areas that are likely to be damp or humid, such as basements and bathrooms. Be sure to clean behind appliances, such as your refrigerator and stove.

Step 2: Seal Up Cracks and Holes

Centipedes can enter your home through small cracks and holes in the walls or floors. Seal up these entry points to prevent them from getting in. Use caulk or foam sealant to fill in any gaps or cracks around windows, doors, and baseboards. You can also use weatherstripping around doors and windows to create a tighter seal.

Step 3: Reduce Moisture in Your Home

Centipedes thrive in moist, humid environments. Reduce the moisture levels in your home by fixing any leaky pipes or faucets, and making sure your bathroom and kitchen are well-ventilated. Use a dehumidifier in areas with high humidity, such as basements or crawl spaces.

Step 4: Use Insecticides

If you have a severe infestation, you may need to use insecticides to get rid of house centipedes. Look for products that are labeled for use against centipedes, and follow the instructions carefully. You can also use sticky traps to catch centipedes as they crawl across floors or walls.

Step 5: Call in the Professionals

If you’ve tried everything and still can’t get rid of your centipede problem, it may be time to call in the professionals. Pest control experts have the tools and expertise to eliminate centipedes and prevent them from coming back.
