I am going to share with the most effective home remedies and strategies which I have personally experienced and found useful to keep spiders out of your basement forever. So, let’s get into them in detail!

How To Keep Spiders Out Of Basement Using Home Remedies Permanently?

Mix some peppermint oil with water in a spray bottle and spray it around windows, doors, and any places in the basement where you’ve seen spiders.

Use Some Vinegar

Use vinegar to keep spiders away. It’s safe for people but spiders hate it. Just put some vinegar in places around your house to stop spiders from coming in.

Ditch Spiders With Citrus

Use citrus fruits like lemons and oranges to keep spiders away. Their strong smells are pleasant to us but too much for spiders. Simply using these citrus scents around your home can make spiders turn and leave.

Seal All Cracks

Close up any cracks. Spiders have to find a way in, so don’t let it be easy! Check the outside of your house for any small cracks or openings where spiders could squeeze through.

Use Essential Oil

Use essential oils to keep spiders away. Some oils can even stop spiders from growing. They smell strong, so be careful when using them in your house. Remember to keep your place clean and think about where you keep important stuff before picking a bug spray.

Use Eucalyptus

Eucalyptus has a strong smell that keeps spiders and other pests away, similar to how citrus, peppermint, and vinegar work. You don’t have to grow a eucalyptus tree to get these benefits. Just using eucalyptus oil is enough to do the job.

Diatomaceous Earth

Diatomaceous Earth is a powder made from ancient algae fossils. To use it against spiders, mix 1 tablespoon of it with water and spray it in places where you think spiders are hiding. You can also use it to protect your garden from pests. Just remember to spray it with water and make sure no one breathes in the dust. Always buy the food-grade kind to be safe.

Cut Down Mulch

Mulch looks nice in our yards and gardens, but spiders like it too. This is because mulch is home to bugs and other small creatures that spiders eat.

To keep spiders away, don’t put mulch too close to your house’s foundation. This stops spiders from easily getting into your home and basement. Also, try to use less mulch in your yard.

Avoid Stacking Wood

Many people don’t know that woodpiles attract spiders looking for a place to live (1). A simple trick to keep spiders out of your basement is to store your wood outside.

Place it in your yard or in a shed, away from your house.

Keep The Basement Neat, Clean

Just like with woodpiles, keeping cardboard boxes in your basement makes it easy for spiders to hide. Cleaning your basement often by vacuuming, dusting, and getting rid of clutter not only keeps it neat but also lets you check for hidden spiders in small spots.

Horse Chestnuts

Horse chestnuts can help keep spiders away. Put them near your windows to stop spiders from coming in and taking over. Remember to replace them when they start to spoil to keep protecting your space.

Carnivorous Plants for Pest Control

Looking for a different way to deal with cellar spiders and other pests? Carnivorous plants, or “predator plants,” could be the answer!

These cool plants can naturally get rid of pests in your home. Plus, they’re easy to take care of and can look really nice.

Catch Spiders Using Traps

Use spider traps that aren’t harmful to catch and kill spiders. Just make sure to get them from a trusted brand. You can also use a special vacuum made for catching spiders quickly when you see them.

Change Exterior Lighting

Changing your outside lights can help with spider problems. Spiders eat bugs, and lights outside your home, like security or porch lights, draw in lots of bugs.

Even lights inside your home can attract them. You don’t have to turn off all your lights to stop spiders. Instead, use bulbs that bugs don’t like as much, such as sodium vapor bulbs. Also, closing your blinds at night stops light from inside your house from attracting bugs and spiders outside. This can help fireflies too.

Final Thoughts

I think keeping spiders out of your basement is all about keeping things clean and using natural smells they don’t like. Simple steps like sealing cracks, using peppermint oil, and not letting clutter pile up can make a big difference. It’s cool that plants and certain lights can help too.
