The American house spider, also known as Parasteatoda tepidariorum, is a common household pest found throughout the United States. These spiders are known for their messy, irregular webs and can be a nuisance to homeowners. If you're dealing with an American house spider infestation, there are several steps you can take to remove them from your home. Here are 7 tips to help you get started.
Understanding American House Spiders
Before we dive into the removal tips, it’s essential to understand the basics of American house spiders. These spiders are typically brown or gray in color and have a distinctive body shape, with a rounded abdomen and long, thin legs. They are relatively small, with most adults reaching a body length of about 1⁄4 inch. American house spiders are harmless to humans and do not bite unless provoked. However, their webs can be a nuisance, and their presence can be a sign of a larger pest control issue.
Tip 1: Seal All Entry Points
One of the most effective ways to prevent American house spiders from entering your home is to seal all entry points. This includes cracks and crevices around windows, doors, and vents, as well as any holes or gaps in your home’s foundation or walls. Use caulk or weatherstripping to seal these areas and prevent spiders from squeezing through. By sealing all entry points, you can help prevent new spiders from entering your home and make it easier to remove existing ones.
Tip 2: Keep Your Home Clean
A clean home is less likely to attract American house spiders. Regularly vacuum and dust, especially in areas where spiders are commonly found, such as basements, crawl spaces, and attics. Pay particular attention to corners and crevices, where spiders like to hide. By keeping your home clean, you can reduce the availability of food and shelter for American house spiders and make your home less appealing to them.
Tip 3: Remove Clutter
Cluttered areas can provide a haven for American house spiders, offering them plenty of hiding spots and food sources. Remove any clutter from your home, including boxes, papers, and clothing. Organize your belongings and store them in sealed containers or bins. By removing clutter, you can reduce the number of places where spiders can hide and make it easier to spot them.
Tip 4: Use Essential Oils
Certain essential oils, such as peppermint and tea tree oil, can help repel American house spiders. Mix a few drops of the oil with water and spray it around the perimeter of your home, as well as in areas where spiders are commonly found. You can also add a few drops of the oil to your vacuum cleaner bag or dustpan to help repel spiders as you clean.
Tip 5: Use Diatomaceous Earth
Diatomaceous earth is a natural, non-toxic substance that can be used to kill American house spiders. Sprinkle the powder around the perimeter of your home, as well as in areas where spiders are commonly found. The powder works by dehydrating the spiders, causing them to die. Be sure to wear a mask when applying the powder, as it can be irritating to the lungs.
Tip 6: Use a Dehumidifier
American house spiders prefer humid environments, so using a dehumidifier can help make your home less appealing to them. By reducing the humidity in your home, you can make it more difficult for spiders to survive and thrive. This is especially effective in areas like basements and crawl spaces, where the humidity is often higher.
Tip 7: Call a Professional
If you have a severe American house spider infestation, it may be necessary to call a professional pest control service. These services can help identify the source of the infestation and provide effective treatments to eliminate the spiders. Be sure to choose a reputable service that uses safe and effective methods to remove the spiders.
