What Nut Is a Natural Spider Repellent?

Many people are afraid of spiders. While few species of spiders are dangerous to people, they can still be a nuisance in the home. If you have a spider infestation or simply wish to keep your home free of spiders, you do not need to turn to commercial insecticides. These products contain toxic chemicals that can harm children and pets, and they can also be quite expensive. Rather, try a natural method of spider control that will not put your household in danger.

Chestnuts are a natural spider repellent.

Chestnuts as Spider Repellent

Many items such as herbs, vegetables and essential oils, function as natural spider repellents, but many people do not know that some types of nuts — namely chestnuts — are also effective. As is true of most nuts, the meat of the chestnut contains an oil that naturally repels spiders because it produces a scent that spiders do not like. Not only are chestnuts effective in deterring household pests like spiders, but once they stop working you can recycle them and incorporate them into your home-decor scheme.


Commercial insecticides work because they contain chemicals like diazinon, carbaryl and methyl parathion, which are toxic to insects — but that are also toxic to pets and humans. Insecticide poisoning may lead to skin rashes and inflammation, vomiting, headaches and, in severe cases, coma or death. Chestnuts, on the other hand, are completely natural and will not leave a toxic residue on the surfaces in your home. Humans can safely eat these nuts and, therefore, ingesting or coming into contact with chestnuts will not cause any bodily harm.

How to Use Chestnuts

If you choose to forgo insecticide sprays in favor of something natural like chestnuts, you will still follow the same basic application procedure. Sprinkle whole chestnuts in the affected areas of your home, namely around door frames and window sills. Spiders are also likely to be found in corners and dusty closets as well as in the attic. Spreading fresh chestnuts around the baseboards in these areas is all you need to do.

Use Chestnuts More Effectively

In order to maximize the efficacy of your pest control efforts, you should also employ some basic sanitation procedures. Keep your floors swept and your carpets vacuumed and regularly check the corners of your ceilings for developing spider webs. Keeping your home clean will root out any nesting spiders and prevent them from building webs. You can also sprinkle citrus peels or tobacco along with the chestnuts to add some extra spider-repelling power. Citrus-based cleaning products can also be used to repel spiders in combination with sprinkling chestnuts.
