Do Spiders Really Hate Peppermint?


If you don’t like critters with 8 legs and a bazillion eyes I suggest you squeeze your eyes almost shut so this page gets blurry, then scroll down far enough so you can’t see the pictures.


We have a large screened-in pool deck and unfortunately it’s prime real estate for spiders, specifically brown widows. And here is where I am torn.

Good – Brown widows are venomous but rather docile and the chances that they will bite my children or pets is pretty low. Or so I’m told, I’m not about to intentionally find out.

*I feel the need to strongly knock on wood right here*

Bad – Brown widows are venomous.

Good – Brown widows tend to take over the territories of the less venomous, but more aggressive (though still on the docile side), black widow.

Bad – Brown widows are venomous.

Good – Brown widows belong in our ecosystem and removing them could screw up the balance.

Bad – I don’t know if I mentioned this, but brown widows are venomous.

The key is to remove the spiders that are there now and figure out a way to keep them away for good. But how?

Thankfully the internet came to the rescue.

Spiders hate peppermint

Step 1: Clear out two corners currently infested by spiders

Step 2: Make peppermint essential oil/water mixture. The site didn’t get specific but they linked to a 4 or 5 ounce spray bottle and said to use 10-15 drops of peppermint essential oil. I decided to mix 10 drops of doTerra brand peppermint essential oil in 4 ounces of water. My use of doTerra isn’t an endorsement, it’s just what I had because I have a friend who sells it.

Step 3: Saturate one corner (the corner next to the door) at initial application. Reapply peppermint spray after rain and every 2-3 days thereafter. Do not spray second corner at any point during this experiment.

Step 4: Keep an eye on both areas over the next few weeks to see if the spiders move back into either corner.

*My experiment is not complete. I will add pictures and updates over the next few weeks.*

August 27, 2013

Spider sacs were removed from the corner near the door:

and the corner a few panels over:

Look for an update once a week until I determine if spiders really do hate peppermint!

UPDATE 8/29/2013
-Both corners are spider-free two days after removal & peppermint application

  1. I use peppermint for mosquito repellent and it works great!

    For spiders I would try a combination of catnip, peppermint, rosemary, lemongrass…and spray like mad! Lol I don’t like spiders!

    I’ll be watching for your updates.

  2. So did it really work?

    I’ve tried eucalyptus oil and peppermint oil sprayed around baseboards and corners on the ceiling. A day later my husband said he saw a spider climb up the wall and when it got to the corner it dropped back to the floor. Not sure if that was a coincidence or if it was actually working. I haven’t personally seen spiders in the rooms I’ve sprayed, but we did get a big one in one of the rooms that I didn’t spray – again, could just be a coincidence! It’s only been a few days, so I’d like to know if this is going to work or if I’m wasting my time.

    I’d really like to know, a month later, did this experiment actually work?

    • Well, no brown widows have moved back in BUT they haven’t moved back into the I sprayed corner either. We have had some huge banana spiders move in, they could account for that too. Or maybe it’s the weather change. So I’m calling this one a big no, simply because the banana spiders moved in.

  3. I wondered if you added any dish soap in your solution? From what I have read you need a few drops to keep the oil in solution with the water (oil and water don’t mix, right). Then a good shake before you spray, to ensure its mixed. If not, I would imagine you are spraying mostly water. I am heading out to get some peppermint oil today. Going to try my own non-toxic experiment.

    • I hadn’t heard this. Since I was spraying in my pool area I wouldn’t add the soap because it could run into the pool with the rain and it’s a struggle keeping the pool chemicals balanced. But, worth a try indoors! My husband used to spray his plants with diluted dish soap, so there is probably some basis there 🙂

  4. Hiiii.. Can someone please confirm if the peppermint works now or not?? I had an spider climbing in my hair last night while sleeping!!!! I was horrified when this woke me up and i saw it was a spider.. Please help, i really dislike spiders in my house and especially on me.

    • That would freak me out!!

      I came to the conclusion that it kinda works, maybe. I haven’t seen any more brown widows but some orb weavers did move in to the area. I dont know if the brown widows were chased out, or if it was the cooling of the weather, or the peppermint. So, I’ll tell you that peppermint can’t hurt but it might not help either.

      • Hahaha thanks meg. I sprayed some peppermint mix around the house.. Ill just keep some insect killer close(sorry enviroment). And ill have to start checking the bed before I go to sleep.
