Why Spiders Can’t Stand Black Pepper

Black pepper (Piper nigrum) is commonly known as a flavorful spice used in a variety of dishes. Apart from its culinary uses, it has been discovered that black pepper can play a role in repelling spiders and other arachnids.

So, let’s uncover the secret behind this spider-deterring magic!

Pepper’s Strong Aroma

The key to black pepper’s efficacy as a spider repellent lies in its strong aroma. Spiders possess sensitive sensory organs that can pick up smells and tastes in their environment.

In fact, a study from the Journal of Functional Ecology found that spiders use their sense of smell to distinguish between venom-sensitive prey and venom-insensitive prey, thus allowing the spider to use less venom on certain prey to conserve their stores.

So, if a spider can tell the difference between a cricket and a cockroach based on smell alone, imagine when they get a strong whiff of black pepper! The pungent smell of black pepper is believed to be irritating to these creatures, making them steer clear of areas where it’s present.

Six Creative Ways To Use Black Pepper Against Spiders

1. Create A Black Pepper Solution

Preparing a black pepper solution is easy and effective in repelling spiders! First, gather your materials, which include water, black pepper, and a spray bottle.

Mix 1 teaspoon of black pepper with 1 cup of water in a spray bottle. Shake well and then spray the solution around windows, doors, and other entry points where spiders may enter.

There’s no special type of black pepper that works the best, just a simple pepper like McCormick Organic Pure Ground Black Pepper will work just fine!

2. Black Pepper Sachets

Fill small sachets or muslin bags with black pepper and place them in areas where spiders are commonly found, such as closets, under furniture, or in the corners of rooms. The strong scent of the black pepper will deter spiders from these areas.

It may be better to use whole peppercorns like Happy Belly Tellicherry Black Pepper Whole Peppercorn for this method.

3. Black Pepper Infused Oil

Infuse black pepper into a carrier oil such as olive oil or coconut oil by heating the oil and adding a generous amount of black pepper. Allow the mixture to cool, then strain out the pepper. Use the infused oil to wipe down surfaces and areas where spiders are present.

Alternatively, you can use black pepper essential oil like Sun Essential Oils – Black Pepper Essential Oil. Just be sure to dilute it by only adding 10-15 drops per 1 cup of water. Then, use it in the same fashion described above.

4. Black Pepper And Vinegar Solution

Combine equal parts black pepper and white vinegar in a bowl and mix well. Use a cloth or sponge to apply the solution to areas where spiders tend to gather, such as baseboards and corners.

5. Black Pepper Potpourri

Create a potpourri mixture using dried black pepper or whole peppercorns, cloves, and other aromatic spices. Place the potpourri in bowls or sachets around the house to create a natural spider-repellent.

6. Create A Black Pepper And Citrus Spray

Combine black pepper with grated citrus peels (such as lemon or orange) and steep them in boiling water. Once cooled, strain the mixture and pour it into a spray bottle. Use this solution to spray around the perimeter of the home and in areas where spiders are likely to enter.

A carefully prepared black pepper repellent can be an effective, natural, and environmentally friendly way to deter spiders from invading your personal spaces.

Give these methods a try and enjoy a spider-free home without resorting to harsh chemicals or expensive products. Remember to reapply the solution as needed to maintain its effectiveness.

Where Should You Apply Black Pepper Repellents To Deter Spiders?

Spiders often enter through open windows or make webs near them. Spray the black pepper solution or other black pepper repellent around window frames and sills to discourage them from coming in or building their homes there.

Don’t forget to reapply often to keep the scent strong.


Spiders love hiding in cracks, crevices, and small gaps in the walls and corners of your home. Apply a black pepper repellent in these areas, paying special attention to those near the floor or ceiling where spiders may be lurking.


As a central part of your home, the kitchen is also a prime target for spiders. To keep them at bay, use your handy black pepper repellent on countertops, under sinks, and inside cupboards where these critters might be trying to find shelter.

Air Vents & Ducts

Spiders can also enter your home through air vents and duct systems. Make sure to give these a good spray with your black pepper solution to deter any eight-legged intruders.

Outdoor Areas

Don’t forget about the exterior of your home! Apply your chosen black pepper repellent around doorways, porches, and patios to create a spider-free barrier.


Spiders often migrate from your garden to your home, so it’s crucial to keep them at bay outdoors. Sprinkle some ground black pepper around your garden, particularly near the base of your home’s walls to form a natural repellent line.

These are just the main places where spiders like to hang out. If you’d like a more detailed list, take a look at our article on the common places where spiders live in your home.

Remember, consistency is key when using black pepper as a spider repellent. Keep applying it regularly, and soon enough, you’ll see a decrease in the number of spiders in your living space!

Additional Natural Ways to Repel Spiders

Besides black pepper, you can also try other natural remedies to repel spiders from your home. Here are a few methods that have been found to be effective in different circumstances.

Vinegar Spray

One easy solution is to make a natural spray with water and vinegar. Just mix equal parts of water and white vinegar in a spray bottle. Apply this mixture to areas where spiders are commonly found, such as window sills, doorways, and crevices.

This strong-smelling solution can deter spiders from settling in those areas. You can read more about why vinegar works to repel spiders here.

Mint And Peppermint

Mint and peppermint are also known for their spider-repelling qualities. You can use either fresh mint leaves or peppermint essential oil like MAJESTIC PURE Peppermint Essential Oil. Place a few leaves or drops of oil in strategic places, or make a spray with water and a few drops of peppermint essential oil.


Another powerful spider deterrent is citrus. Lemon oil, for instance, can be effective in repelling some species of spiders. Feel free to add a few drops of lemon or other citrus essential oils to your natural spray. You can also scatter citrus peels near potential spider havens.


Many spiders dislike strong scents, and eucalyptus is a perfect example. Try placing a small eucalyptus tree near your entrance, or expose some dried leaves in strategic places around your home.


Cedar also has a distinct fragrance that spiders dislike. Incorporate cedar items into your home – cedarwood furniture, cedar mulch in the garden, or even cedar oil. Homode Cedar Blocks comes with a combination of cedar blocks, hangers, balls, rings, and sachets to place in spider-prone areas.

When it comes to repelling spiders, keep in mind that different methods work for different spiders, and there’s no one-size-fits-all solution. Feel free to mix and match these deterrents for better results, and remember that being diligent in your efforts will help keep spiders away from your home naturally.
