How Often to Use Peppermint Oil for Spiders

Spiders can be great in your garden, munching on insects and keeping things in check, but most of us don’t want them freely roaming inside our homes. 

Indoor spaces might provide spiders with the food, water, and shelter they need, but it’s best to take control and keep them out of your living spaces.

Fortunately, essential oils have gained significant recognition as natural alternatives to chemical insecticides for effective pest control in your home. 

Among these oils, Peppermint Oil has emerged as a potent natural insect repellent, particularly successful in deterring spiders, as well as other pests. 

In this article, we’ll explore the efficacy of Peppermint Oil in repelling spiders, explore safe application methods, and recommend how often to use it to achieve the best results.

Does Peppermint Oil Repel Spiders?

Essential oils, which are concentrated extracts derived from plants, offer a wide range of properties, including their ability to repel insects. This makes them highly promising natural solutions for pest management. 

Their uniquely potent aromas have been shown to disrupt the odor-sensing abilities of insects, causing them to be repelled when they come into contact with essential oils.

Research has not only shown Peppermint Oil as an effective solution against common pests like mosquitoes, but has also demonstrated its effectiveness against various spider species. 

One study showed exposing recluse spiders to essential oils (including peppermint) for a period of 24 hours resulted in the mortality of many of the spiders.

Another research study found that Peppermint Oil strongly repelled brown widows and European garden spiders, which are two different invasive spider species.

And it’s also worth mentioning that a combination of essential oils, including Peppermint Oil, was shown to result in more than 80% mortality of a variety of arthropod pests, which include flies, mites, and other insects, which are close relatives of many types of spider species.

It’s safe to say that Peppermint Oil has a ton of potential when it comes to repelling pesky insects, including spiders.

Outdoor Use of Essential Oils

When it comes to dealing with those sneaky spiders invading your home, they find their way in through windows, tiny cracks, and openings around your house. 

You might even find spider infestations in sheds, structures around your garden, or lurking on your porch, which isn’t a very welcoming sight.

If you're considering using Peppermint Oil outdoors, it's a smart move to test it on a small area first, just to be sure it plays well with any of the crops you might have in your garden. 

Regardless, you’ll be glad to know that essential oils, including Peppermint Oil, are naturally biodegradable when used in small doses.

Unlike traditional chemical-based pest control methods, Peppermint Oil may be an eco-friendly solution to pests, derived from renewable plant sources. 

Plus, its non-toxic nature may make it a safer alternative for indoor and outdoor use for individuals concerned about exposure to harsh chemicals.

How to Use Peppermint Oil to Keep Spiders Away

Here's a step-by-step guide on how to create your very own spider spray using Peppermint Oil:

  1. Gather Your Ingredients: For this natural spider spray, you'll need a few drops of pure Peppermint Oil, water, and a small amount of dish soap.

  2. Mix the Solution: In a small container, combine the Peppermint Oil, water, and a drop or two of dish soap. The dish soap helps emulsify the oil and water, ensuring an even distribution.

  3. Transfer to a Spray Bottle: Once you've mixed the solution, carefully pour it into a clean and empty spray bottle. Make sure to use a spray bottle that's specifically for homemade solutions, so there's no risk of any chemical residue interfering with the Peppermint Oil.

  4. Target Spider-Prone Areas: Now, it's time to take aim at those spider hotspots! Spray the Peppermint Oil solution on corners, window sills, doorways, and any other areas where you've noticed spider activity. Spiders can't stand the potent peppermint scent, so they'll be inclined to stay far away from these treated spots.


  1. Go Straight to the Source: If you prefer a more direct approach, you can use undiluted Peppermint Oil instead. Take some cotton balls or pieces of cloth, and apply a few drops of Peppermint Oil on them.

  2. Strategically Place the Infused Materials: Now, scatter these Peppermint Oil-infused materials around your home, focusing on areas where spiders are likely to hang out. Corners, windowsills, and doorways are excellent spots to start. As the Peppermint Oil evaporates, it releases that distinctive scent that spiders detest, creating an environment they'll want to avoid.

How Often Should You Use Peppermint Oil for Spiders?

The frequency of applying Peppermint Oil as a spider repellent is an important aspect of its effectiveness. 

Finding the right balance ensures the best results in keeping those eight-legged intruders at bay. 

Here's what you need to know about the application frequency, factors to consider, and practical tips for maintaining a spider-free environment.

Severity of the Spider Infestation

The severity of the spider infestation in your home is the first factor to consider. If you're dealing with a minor spider presence or occasional sightings, a weekly application of Peppermint Oil should suffice. This frequency allows the scent to linger and create a deterrent effect.

Efficacy of the Repellent 

Keep a close eye on the results after each application. If you notice a decrease in spider activity, it's a positive sign that the Peppermint Oil is doing its job.

However, if spiders persist, it might be necessary to increase the application frequency. Adjust the frequency based on how effectively the Peppermint Oil is keeping spiders away.

Outdoor Application 

When using Peppermint Oil outdoors to prevent spiders from entering your home, consider environmental factors like weather conditions. 

After heavy rain or exposure to the elements, the peppermint scent may dissipate faster, reducing its deterrent effect. In such cases, it's best to reapply the oil every two to three days to maintain a strong barrier against spiders.

Keeping Track of Spiders

Keep a log or mental note of spider activity in and around your home. Monitor their movement patterns and identify their common hangout spots. This information will help you determine the most strategic areas for applying Peppermint Oil and enable you to evaluate the effectiveness of your repellent efforts.

Consistency Is Key

Consistent application of Peppermint Oil is crucial for maintaining a spider-free environment. Stick to a regular schedule to ensure that the peppermint scent remains potent and discourages spiders from entering your living spaces.

Safety Tips For Using Essential Oils as Pesticides

While Peppermint Oil is generally safe, adhering to essential oil safety guidelines is essential:

  • Pet Considerations: Pet owners should exercise caution when using essential oils, including Peppermint Oil, as certain animals may be sensitive or allergic to them. Consult a veterinarian if there are concerns regarding your pets' reaction to essential oils.

  • Dilution: When applying essential oils on the skin or in sprays, ensure proper dilution with a carrier oil or water to avoid skin irritation or sensitization.

  • Avoid Direct Contact: Direct contact with undiluted essential oils should be avoided, as their high concentration can cause skin irritation. It is advisable to wash hands thoroughly after handling essential oils.

  • Ventilation: Use essential oils in well-ventilated areas to prevent overpowering scents.

  • Patch Testing: Prior to extensive application, conduct a small patch test to ensure compatibility of the essential oil with the intended surface or area.
