Spiders can easily live comfortably in a few places in your house, such as the basement. Basements are dark, dingy and can be a favorite place for spiders and other insects too.

Most basements, if not kept clean, tend to be filled with spider webs and many other pests. A well-lit basement can be creepy too if there are spiders present.

Keeping spiders away from the basement, your family, and your house overall should be your first priority. There are both natural and chemical spider repellants which you can use to drive spiders away from the basement. There are also various techniques and precautions that you can take to keep spiders away.

However, one should know that to get rid of spiders from your basement is a process and not a day’s affair. You need to start off by looking for places they can hide and block those spots. After that comes the cleaning of cobwebs and then the use of repellants.

Following are a few tips on how to get rid of spiders from your basement.

1. Seal all small openings and cracks

First of all, search for any cracks or gaps or crevices in and around your basement. You need to seal those gaps or openings because they are the gateways through which spiders enter the basement.

Thereafter, seal all the openings carefully using caulk. It is a good idea to attach mesh screens on the windows and fix the doors.

2. Refrain from stacking wood

Spiders such as black widows like to creep inside woodpiles and stay in there because of the insects present in such piles. If you are the kind who stacks wood in the basement, it is time to stop. Store the wood in the backyard or somewhere outdoors. There should be a good distance between the pile and the house.

Invest in building a shed for the woodpile outside during rainy season.

3. No clutter

Basements are areas in the house that are most cluttered. That is what attracts the spiders to the basements. Spiders thrive in places that are cluttered or messy because clutter attracts more insects.

The only way to declutter the basement is to organize and clean the basement. Begin by removing all the things that are not needed anymore. Give them off or hold a yard sale for your things.

Keep unnecessary things away from the wall in order to avoid the formation of spider webs on them. Also, it is advised to store things in plastic or other material boxes instead of paper, since paper boxes are prone to cockroach attacks.

4. Eliminate other pests

Spiders usually harbor in basements in order to search for more foods. Pests like mosquitoes, termites, tiny roaches etc. are delicious foods for spiders. Therefore, removing these pests from the basements will decrease the chances of spiders dwelling in the area.

Get rid of pests by using common pest repellants found in stores.

5. Spray Peppermint Oil

Natural oils like peppermint are very strong and hated by spiders and other insects too. The smell is too pungent for these insects to bear and hence, peppermint oil is a perfect repellant to keep these crawly creatures away.

Peppermint oil is mixed with water to make it last longer. This also dilutes the oil in order to avoid any skin irritation on people or pets at home.

You can even make peppermint oil balls, by soaking cotton balls with the oil. Place them in spots around the basement that seem to be most prone to spiders.

6. Make a Homemade spider spray

Vinegar, along with peppermint oil is a very effective combination to use against spiders. This will repel not only spiders but also other pests in the basement like mice and ants.

What you will need:

  • 10 drops peppermint essential oil
  • 1/2 cup distilled white vinegar
  • 1 1/2 cups water


  • Take a small spray bottle and mix all the ingredients in it. Shake well.
  • Spray on all the four corners of the basement, underneath sinks, window sills, and any such spots you think are prone to spiders.
  • Store in a cool, dark place.

7. Get a pet

Having pets at home is a great way to keep away pests like spiders. The best of them all are cats since they tend to chase around anything that moves swiftly. Having pets at home will act as a natural spider repellant.

Take your pet to the basement frequently to look for any moving creature. However, care should be taken in protecting your pet from the bites of poisonous spiders.

8. Spray lemon oil

Lemon oil also works as a good spider repellant. If you don’t have peppermint oil at home, you can opt for this oil.

9. Use Eucalyptus Oil

Eucalyptus oil has a very strong smell, and it has many essential properties. This oil works best to drive away spiders from anywhere. All you need to do is soak cotton balls in eucalyptus oil and keep them in the corners of the basement, the windows, any cracks etc.

Another plus point of using it is the ability of eucalyptus oil to repel mosquitoes and snakes.

10 Fumigate the basement

Apart from all the ways mentioned above, to repel spiders, it is best if you can fumigate the basement to kill spiders. You can fumigate using chemical pesticides or natural solutions like peppermint oil or lemongrass oil.

Remember that using chemical pesticides is safe for your basement, but not for other areas of the house, like the kitchen.


Spiders are a hassle if you have them crawling in areas such as the basement. Basements should be kept clean and tidy because of the many items that are usually stored in them. Use any one of the techniques on how to keep spiders out of your basement mentioned above to help your basement free from spiders.
