Spider Prevention. 8 Simple Ways to Keep Spiders Out of Your Home


Spiders are a common problem in many homes, especially during the warmer months. While most spiders are harmless, their presence can be unsettling and even frightening for some people. Additionally, some species of spiders can be dangerous and pose a threat to humans and pets. Therefore, it is important to take steps for spider prevention in the home.

Identifying Common Spiders

There are several species of spiders that are commonly found in homes, including the house spider, wolf spider, and cellar spider. House spiders are small and brown with long legs, while wolf spiders are larger and have a hairy appearance. Cellar spiders are also known as daddy longlegs and have long, thin legs.

To identify a spider, look at its body shape, color, and leg length. You can also use an online identification guide or consult with a pest control professional.

Reasons to Prevent Spiders

While spiders may play an important role in controlling insect populations, there are several reasons why you may want to prevent them from entering your home. One reason is the health risks associated with spider bites. While most spider bites are harmless, some species such as the black widow and brown recluse can cause serious health problems. Spider prevention inside as well as outside the home is also important.

Another reason to prevent spiders is the damage they can cause to property. Spider webs can be unsightly and difficult to remove, especially if they are in hard-to-reach places. In addition, spider webs can collect dust and debris, which can make your home look dirty.

Sealing Cracks and Gaps

Spiders can enter homes through small cracks and gaps in windows, doors, and walls. To prevent spider entry, seal any cracks or gaps with caulk or weatherstripping. Pay special attention to areas around pipes, vents, and electrical outlets.


Keeping the Home Clean

Spiders are attracted to clutter and debris, so keeping your home clean can help deter them from entering. Vacuum regularly to remove dust and debris from floors and corners. Wipe down surfaces with a damp cloth to remove cobwebs and spider eggs.

Vacuuming Regularly

Vacuuming is an effective way to remove spider webs and eggs from your home. Use a vacuum with a crevice tool attachment to reach tight spaces like corners and baseboards. Be sure to dispose of the vacuum bag or empty the canister outside of your home.

Removing Clutter

Clutter provides hiding places for spiders, so removing it can help prevent infestations. Declutter your home by getting rid of items you no longer need or use. Store remaining items in sealed containers to prevent spiders from nesting in them.

Utilizing Essential Oils

Essential oils like peppermint, lavender, and tea tree oil can repel spiders. Mix a few drops of your preferred oil with water in a spray bottle and spray around windows, doors, and other entry points. You can also place cotton balls soaked in essential oils in areas where spiders are likely to enter.

Installing Screens

Installing screens on windows and doors can prevent spiders from entering your home. Choose screens with a fine mesh to keep even the smallest spiders out. Be sure to repair any holes or tears in existing screens.

Utilizing Natural Repellents

Natural spider repellents like diatomaceous earth and citrus peels can be effective at keeping spiders out of the home. Sprinkle diatomaceous earth around entry points and in areas where spiders are likely to hide. Place citrus peels in areas where spiders are likely to enter.

Utilizing Chemical Repellents

Chemical spider repellents like insecticides and sprays can be effective at keeping spiders out of the home. However, they should be used with caution as they can be harmful to humans and pets. Follow the instructions carefully and keep children and pets away from treated areas.

Calling a Professional Exterminator

If you have a severe spider infestation or are unable to control it on your own, it may be necessary to call a professional exterminator. Look for a reputable company that uses safe and effective methods for spider control.

Natural Prevention Strategies

There are several natural strategies that you can use to prevent spiders from entering your home. One strategy is to keep your home clean and clutter-free. Spiders are attracted to cluttered areas as they provide hiding places and food sources. By keeping your home clean and clutter-free, you can reduce the likelihood of spiders entering your home.


Another natural strategy is to use essential oils and herbs to repel spiders. Peppermint oil, lavender oil, and eucalyptus oil are all known to repel spiders. You can also use herbs such as mint, rosemary, and lemongrass to repel spiders.

Planting spider-repelling plants in and around your home is another natural strategy for preventing spiders. Plants such as lavender, mint, and marigolds are known to repel spiders. By planting these plants in and around your home, you can reduce the likelihood of spiders entering your home.

Chemical Prevention Strategies

If natural prevention strategies do not work, there are several chemical prevention strategies that you can use to prevent spiders from entering your home. Common spider repellents include sprays that contain pyrethrin or permethrin. These chemicals work by disrupting the nervous system of insects and arachnids.

Insecticides such as bifenthrin and cyfluthrin are also effective at killing spiders. However, it is important to use these chemicals with caution as they can be harmful to humans and pets. Always read the label and follow the instructions carefully when using insecticides.

DIY Prevention Solutions

If you prefer to use natural prevention strategies, there are several DIY solutions that you can try. One solution is to make your own spider-repellent spray using essential oils such as peppermint, lavender, and eucalyptus. Simply mix a few drops of essential oil with water in a spray bottle and spray it around your home.

Another DIY solution is to make your own spider traps using household items such as cardboard tubes, glue, and bait. Simply place the bait in the cardboard tube and cover it with glue. Place the trap in areas where spiders are likely to be found, such as closets and basements.
