Spiders 9

Spiders, while beneficial to the ecosystem, are not always welcome guests in our homes. Whether it’s the sight of them that makes you shudder, or the thought of walking into a cobweb, you might be searching for the best spider deterrent. If so, you’re in the right place. This article will delve into the most effective spider deterrents, how they work, their costs, and where you can find them.


The best spider deterrent depends on personal preference and situation. Natural deterrents include essential oils such as lavender, peppermint, and eucalyptus, citrus fruits, and vinegar. Store-bought options include Mighty Mint Peppermint Oil Spray, BRISON Ultrasonic Pest Repellent Plug-in, and Diatomaceous Earth. Preventative measures like sealing cracks and maintaining cleanliness are also effective. Always choose a deterrent that is safe for your family and the environment.

Natural Spider Deterrents

Essential Oils

Spiders are known to dislike certain scents, making essential oils an effective deterrent. Essential oils like lavender, peppermint, eucalyptus, tea tree, and citronella can be mixed with water in a spray bottle and applied around the home to keep spiders at bay.

Citrus Fruits

Citrus fruits are another natural repellent. Spiders dislike the scent of lemons and oranges, so you can create a simple repellent by mixing the juice of a citrus fruit with water and spraying it around your home.


Vinegar is another effective spider deterrent. Mix equal parts of white vinegar and water in a spray bottle and spray it directly onto spiders or around areas where you frequently see them.

Store-Bought Spider Deterrents

If making your own spider deterrent does not appeal to you, there are several store-bought options available. Some popular options include:

  • Mighty Mint Peppermint Oil Spray: This is a natural spider repellent that uses the strong scent of peppermint to keep spiders away.
  • BRISON Ultrasonic Pest Repellent Plug-in: This device emits ultrasonic waves that are said to repel spiders and other pests.
  • Diatomaceous Earth (DE): A natural powder made from tiny fossilized aquatic organisms, DE kills spiders by lacerating their exteriors, leading to dehydration.

Costs Associated with Spider Deterrents

The costs of spider deterrents can vary widely. Natural deterrents like essential oils and vinegar are typically inexpensive, while store-bought deterrents can range from affordable to quite expensive, depending on the product. Professional extermination services can cost between $150 and $300 for a one-time treatment, but costs can rise if multiple treatments are needed.

Where to Purchase Spider Deterrents

Spider deterrents can be purchased at local stores, online retailers like Amazon, or made at home with readily available ingredients.

Preventative Measures

In addition to using deterrents, it’s important to take preventative measures to keep spiders out of your home. This includes sealing cracks and gaps in walls, windows, and doors, and maintaining a clean and clutter-free environment. Regularly vacuuming and dusting can also help to keep spiders at bay.


While spiders play an essential role in the ecosystem by controlling other pests, they’re not always welcome in our homes. Thankfully, there are several effective spider deterrents available, both natural and store-bought. Whether you choose to make your own deterrent at home or purchase one, the key is to find a deterrent that works best for you and your situation. Remember, the best spider deterrent is the one that keeps spiders out of your home while being safe for you, your family, and the environment.
