Are you tired of unwanted eight-legged visitors in your home? Spiders can be a nuisance, and their webs can be a real eyesore. While it’s impossible to completely eliminate spiders from your surroundings, there are several steps you can take to discourage them from entering your house. In this article, we’ll explore the reasons why spiders invade homes, the most common types of spiders you might encounter, and provide you with a comprehensive guide on how to keep them out.
Why Do Spiders Enter Homes?
Before we dive into the solutions, it’s essential to understand why spiders enter homes in the first place. Here are some reasons:
- Food availability: Spiders are attracted to homes with an abundance of insects, their primary food source. If your home has a lot of flies, mosquitoes, or moths, it’s likely to attract spiders.
- Warmth and shelter: Spiders seek warmth and shelter, especially during the colder months. Your home provides the perfect environment for them to thrive.
- Moisture: Spiders need a certain level of humidity to survive. If your home is prone to dampness or has a lot of moisture, it can attract spiders.
Common Types of Spiders Found in Homes
While there are many species of spiders, some are more common in homes than others. Here are a few:
- House Spider (Parasteatoda tepidariorum): Also known as the cupboard spider, this is one of the most common spiders found in homes. They’re harmless and help to keep insect populations under control.
- Cellar Spider (Pholcus phalangioides): Also known as the daddy long legs spider, this spider is recognized by its long, thin legs. They’re harmless and actually help to keep other spider populations under control.
- Wolf Spider (Lycosidae family): These spiders are large and hairy, and are often mistaken for tarantulas. They’re harmless to humans and actually help to keep insect populations under control.
How to Keep Spiders Out of Your House
Now that we’ve explored the reasons why spiders enter homes and the most common types of spiders you might encounter, let’s dive into the solutions. Here are some effective ways to keep spiders out of your house:
Seal All Entry Points
Spiders can squeeze through tiny cracks and crevices, so it’s essential to seal all entry points around your home. Here are some areas to focus on:
- Windows and doors: Check for any gaps or cracks around windows and doors, and seal them with caulk or weatherstripping.
- Vents and chimneys: Install screens or mesh over vents and chimneys to prevent spiders from entering.
- Pipes and electrical outlets: Seal any gaps or cracks around pipes and electrical outlets with caulk or steel wool.
Keep Your Home Clean
A clean home is less likely to attract spiders. Here are some tips:
- Vacuum regularly: Regular vacuuming can help to reduce insect populations, which in turn can help to reduce spider populations.
- Dust regularly: Dusting can help to reduce the number of insects and spiders in your home.
- Keep your home clutter-free: Cluttered homes can provide shelter for spiders, so keep your home tidy and organized.
Reduce Moisture
Spiders need a certain level of humidity to survive, so reducing moisture in your home can help to discourage them. Here are some tips:
- Use a dehumidifier: A dehumidifier can help to reduce the moisture levels in your home, making it less appealing to spiders.
- Fix any leaks: Fix any leaks or water damage in your home to reduce moisture levels.
- Improve ventilation: Improve ventilation in your home by opening windows and using fans.
Use Natural Deterrents
There are several natural deterrents you can use to keep spiders away. Here are a few:
- Essential oils: Certain essential oils, such as peppermint, lavender, and tea tree oil, can help to repel spiders. Mix a few drops of the oil with water and spray it around the perimeter of your home.
- Vinegar: White vinegar can help to repel spiders. Mix equal parts water and vinegar in a spray bottle and spray it around the perimeter of your home.
- Diatomaceous earth: Diatomaceous earth is a natural, non-toxic substance that can help to repel spiders. Sprinkle it around the perimeter of your home and in any areas where spiders are present.
Use Insecticides
If you have a severe spider infestation, you may need to use insecticides. Here are some tips:
- Use a spider-specific insecticide: There are many insecticides on the market that are specifically designed to kill spiders. Look for products that contain ingredients such as pyrethrin or permethrin.
- Follow the instructions carefully: Always follow the instructions on the label carefully, and take necessary precautions to avoid exposure.
- Use insecticides as a last resort: Insecticides should be used as a last resort, as they can also harm beneficial insects and pets.
Conclusion
Keeping spiders out of your house requires a combination of sealing entry points, keeping your home clean, reducing moisture, using natural deterrents, and using insecticides as a last resort. By following these tips, you can help to reduce the number of spiders in your home and keep them from coming back.
Q: What are the most common types of spiders that invade homes?
There are several types of spiders that commonly invade homes, including house spiders, cellar spiders, wolf spiders, and black widow spiders. House spiders are the most common type of spider found in homes and are typically harmless.

It’s worth noting that most spiders are harmless and can actually be beneficial to have in your home, as they help to control insect populations. However, if you’re concerned about spiders in your home, it’s a good idea to take steps to prevent them from entering in the first place. This can include sealing up any cracks or crevices around windows and doors, keeping your home clean and clutter-free, and using a dehumidifier to reduce moisture levels.
Q: How do spiders get into my house?
Spiders can get into your house through a variety of means, including cracks and crevices around windows and doors, vents, and pipes. They can also be brought into your home on objects such as firewood, plants, and boxes. In addition, spiders can enter your home through open doors and windows, particularly during the fall and spring when they are more active. It’s also possible for spiders to enter your home through the soil and mulch around your foundation, particularly if you have a crawl space or basement.
To prevent spiders from entering your home, it’s a good idea to seal up any cracks or crevices around windows and doors, and to install door sweeps or weatherstripping around doors.

You can also use herbs and spices, such as mint, basil, and cinnamon, to repel spiders. Simply place a few sprigs of these herbs in areas where spiders are present, or sprinkle a small amount of cinnamon powder around the perimeter of your home.
Another natural way to repel spiders is to use diatomaceous earth, a non-toxic powder made from the fossilized remains of tiny aquatic organisms. This powder can be sprinkled around the perimeter of your home and in areas where spiders are present, and can help to dehydrate and kill spiders.
