If you’re looking for the answer to the question – does peppermint oil kill spiders, then you’re at the right place.
In one word – the answer is NO.
Peppermint oil, or any other essential oil, doesn’t kill spiders.
But peppermint oil is a good spider repellent.
Peppermint oil does repel spiders and can cause spiders to quit your home.
Some essential oils do have insecticidal properties. But they’re not pest killers.
They can act as a pest repellant only up to a certain degree. And essential work only during phases of low infestation levels.
Relying solely on essential oils as a means of pest control will not solve your pest problem.
Essential oils, especially peppermint and eucalyptus essential oils, can act as a repellant to bugs that don’t pose any infestation threat.
So, essential oils can keep away insects like centipedes, spiders, and millipedes that don’t bring infestation problems.
But are essential oils a permanent solution to pests like cockroaches, bed bugs, termites, and ants?
No, they’re not.
To get rid of them from your home, hiring a pest controller is the best option.
Why Peppermint Oil Repel Spiders?
Spiders hate peppermint oil. There are two reasons for it.
First, a strong odor from peppermint essential oil repels the spiders.
Spiders avoid liquids that emit a strong odor.
Second, essential oils have monoterpenoids.
Monoterpenoids are a botanical fumigant that repels many bugs.
There’s scientific research to back the claim that peppermint oil repels spiders.
In a 2010 study, researchers have observed monoterpenoids have a repelling effect on spiders.
Another thesis researchers’ wrote concluded that peppermint oil is a viable preventive solution against arachnids, ants, earwigs, and crickets.
How To Keep Spiders Away With Peppermint Oil?
Using peppermint oil for spiders is an easy task.
All you’ve to do is add 5-7 drops of essential oils in 16-20 ounces of water.
Add 2-3 few drops of dish soap, shake well, and pour the mixture in the spray bottle.
Spray the mixture in dark places and corners of your home where spiders can hide.
Don’t forget to spray it underneath your furniture, around your home’s perimeter, and in places like the garage or basement.
But there’s a catch.
As peppermint oil isn’t an insecticide, you’ll have to spray it more often. Say thrice or four times a week.
That would be an ideal spraying schedule of spray to repel spiders from your home.
The most important thing to keep in mind is that you use a quality peppermint essential oil.
The essential oil should be all-natural extract and cold condensed. If it isn’t, then the spray won’t work.
There are many fake essential oils available in the market.
Some are just fragrances. And some are mixed with vegetable oils.
You must avoid using these essential oils to repel spiders.
The hallmark of an original essential oil is that it’s a bit expensive, it’s packed in a dark glass bottle, and it has its country of origin and biological name mentioned on the bottle.
For your reference, the biological name of peppermint is Mentha piperita L. plant.
Apart from peppermint essential oil, other oils repel spiders.
- Citrus essential oil.
- Eucalyptus essential oil.
- Lavender essential oil.
- Tea tree essential oil.
- Citronella oil.
In addition to using an essential oil, keep your home clean, clear of any clutter, and seal any cracks and gaps on your home’s walls and perimeter.
Spiders sneak through these gaps to get inside your home, looking for shelter, food, and mate.
Keep your home free from insects. If there are insects and bugs inside your home, then spiders will get inside your home to eat them.
Side Effects On You While Using Essential Oils To Repel Spiders
There can be side effects of peppermint essential that you need to be aware of.
National Association of Holistic Aromatherapy states the following side effects –
- Irritation on the skin because peppermint oil contains methanol.
- Muscle pain and weakness
- Distorted vision.
The best part is that these side effects are temporary.
And these side effects can only occur if you use significant dosages of undiluted peppermint essential oils in small rooms.
The best way to null these side effects is by using essential oils in the manner described above.
Also, do not spray the entire house at once, keep your windows open while spraying, and ensure that you don’t spray it on your skin.
Is Peppermint Essential Oil Safe For Pets?
No, peppermint essential oil isn’t safe for pets.
If you have cats or dogs inside your home, avoid using peppermint essential oil.
Instead, use other oils that we mentioned in this post.
As per ASPCA, mint, and methanol are toxic to dogs and cats.
If dogs and cats sniff at the peppermint essential oil, you sprayed in your home. It can make them sick.
It’d be best for your pets that you use other essential oils.
And if you’re using peppermint essential oil, spray it at places where your pets don’t have access.
What If You see Spiders Even After Spraying?
Spiders are sneaky creatures, and they’re great at hiding in tight places.
If there are physical sightings of spiders after spraying, then it means spiders are escaping the areas where you’ve sprayed.
Or you’re not spraying often enough.
In either case, you’d need to know the tricks to get a spider out of hiding.
You’d need to strategically use the baits and lures at the right places to get them out, trap them, and dispose of them.
Should You Kill A Spider?
Spiders are harmless creatures.
They’re inside your home to escape the temporary weather changes outside, food, shelter, and, as we stated earlier, to mate.
And the guts that splash out after you smash a spider can give you some serious skin issues if it touches your skin.
So, it’d be best if you don’t kill a spider.
Lure the spider out, trap it, and drop it away from your home.
Peppermint oil doesn’t kill spiders, but it repels them.
But using undiluted peppermint essential oil to get rid of spiders can have some disturbing side effects on you.
The best way to make a peppermint oil spray is by adding 5-7 drops of pure peppermint essential oil with 20 ounces of water.
To add more punch to it, add 2-3 drops of dish soap.
Peppermint oil is unsafe for pets. So, if you’ve pets, do not use peppermint oil.
