How to Keep Spiders Out of a Garage

The sight of a spider crawling up the wall of your garage can be startling, especially if you have arachnophobia or if a poisonous one has ever bitten you. Spiders are not discreet because they can weave their webs anywhere in your house, including your garage.

You do not have to worry about venomous bites because most house spiders are not harmful. They may help eradicate creepy insects from your house. However, if spiders freak you out and you want to eliminate them from your garage, you should understand what attracts them to your home and how you can kill them.

Spiders love dark places, and your garage might be ideal for them because it’s mostly dark, and a lot of stuff is stored in there. You can easily be frustrated if your garage is full of spiders; however, putting in a little effort can help ensure that your garage is spider-free.

Read on to learn how to get rid of spiders in the garage:

What Can Attract Spiders to Your Garage?

Spiders are mainly attracted by darkness, food, and flying insects. Therefore, if your garage is full of flies and mosquitoes, it will most likely attract spiders. Spiders can easily find their way into your garage through doors, unused heater vents, windows, and other openings. They might also creep in through your garden or driveway.

Should I Kill Spiders in My Garage?

If you cannot stand a spider in your house or garage, your first instinct might be to smash it or eliminate it. However, it is best to capture and release it outside instead of smashing it if you can. When you do this, both parties will be happy with the outcome.

However, it’s normal if you can’t stomach spiders in your garage or home, especially if there is an infestation. When you are in such a situation, you can use natural remedies to eliminate the spiders from your garage.

How Do I Keep Spiders Out of My Garage Naturally?

There are many natural solutions to keeping spiders out of the garage. The solutions require a little more effort than regular cleaning; however, they are less costly than getting an exterminator. Here are some tips to help you keep spiders out of your garage naturally:

Eliminate Clutter From the Garage

You may use your garage as an extra storage space. While having extra space is perfectly okay, allowing it to become disorganized or over-cluttered is most likely to attract spiders. It is prudent to regularly go through the items in your garage and get rid of things you do not use. Do not be tempted to hoard anything because it will eventually lead to clutter.

Ensure that all your storage bins are in a designated area, and don’t leave any loose items lying around. Having a clean and organized space will make it easier for you when clearing cobwebs and help you have a clear view of any crevices or dark corners.

Keeping the garage well aerated and ensuring that the door closes tight will ensure that insects that attract spiders don’t get into your garage in the first place.

Make Natural Spider Repellent Using Peppermint Oil

Using peppermint essential oil can help you eradicate crawly creatures and spiders from your home. The following peppermint spray formula will help you eliminate spiders from your garage:

What You Need:

  • Five drops of peppermint oil
  • 2 cups of water
  • Five drops of dish soap
  • A spray bottle


  • Pour the four ingredients into the spray bottle. A glass spray bottle is preferable because essential oils tend to break down plastic over time.
  • Shake the bottle well to ensure that the ingredients mix well.
  • Spray the area of your garage where the spiders may be hiding. These include crawl spaces, crevices, and dark corners.
  • Spray any significant entry points such as window sills and baseboards.

This natural remedy is effective at repelling spiders and other crawling insects. You can have a bottle on hand to ensure that spiders stay away.

Remove Any Food Source

Having insects like ants, flies, and bees in your garage is not only annoying but also contributes to a spider’s food source. Getting rid of the insects will also help you eradicate spiders because they will have to find food elsewhere.

Glue bug traps play a significant role in helping you eliminate the spiders’ food supply.

Clean Your Garage Regularly

While getting rid of clutter helps you eliminate spiders from your garage, regular vacuuming, sweeping, and mopping make a significant difference when dealing with spiders. You should always look out for spider webs, feces, and egg sacs when cleaning your garage and get rid of them.

Spiders will not build a home in a place where you are constantly tearing it down; hence, eliminating cobwebs from your garage will help you eradicate spiders because they do not want to keep rebuilding them every time.

Additionally, getting rid of egg sacs before hatching is an excellent way of preventing a spider infestation in your garage. Finding spider poop in your garage can be complicated because it resembles ink stains; however, cleaning the garage and clearing the poop will help prevent disease transmission to your family members.

Scatter Horse Chestnuts Around the Garage

Horse chestnuts are a unique spider repellent. While other people think that this is an urban legend, others swear by the results of the remedy. Spiders may find horse chestnuts repulsive because they contain a chemical called saponin.

The chemical is bitter and might even be toxic for them. You can place horse chestnuts around window sills and the corners of your garage. If you have any pets, ensure the chestnuts are out of reach because they may be toxic.

Use Vinegar Spider Spray

White vinegar is an excellent form of spider control. Using a vinegar spider spray will help with the infestation and might kill spiders on the spot. Vinegar contains acetic acid, which burns spiders on contact, killing them.

You will need the following to make the spray:

  • 1 cup white vinegar
  • 1 cup water
  • A spray bottle

Mix the ingredients well and spray the areas where spiders frequent. Such places include crevices, crawl spaces, doorways, and along window sills. You can also place dishes filled with vinegar in corners and entry points.

What Can I Spray in My Garage for Spiders?

If all your natural efforts of preventing a spider infestation fail, it might be time to turn to chemicals and get the best spider repellent. You can buy an insecticide that is specifically designed to repel spiders. Ensure that you follow directions carefully and keep an eye on your pets and children. It would help if you sprayed anywhere you’ve noticed spiders, including along walls, floors, and windows.

You can use boric acid, which is a popular insecticide, to eliminate spiders from your garage. However, be careful when using it because it can harm humans and pets when they ingest it.

If you want to eliminate spiders from your garage, there are several ways of doing it. You can opt for natural solutions or spider repellents. Despite your choice, spray the mixture around the edges of corners, walls, or anywhere you found the spiders when cleaning the garage or maintaining your garage door opener.
