Why You Need a Fast, Pet-Safe Spider Repellent This Fall

  

We got bitten by common household spiders last night as we slept very itchy bites. It was cool outdoors and all the windows were open. Now I know Diatomaceous Earth food grade works, but it’s kind of messy. So, I started wondering: would adding 6 drops of peppermint oil with Dawn dish soap and water in a spray bottle work?

Well apparently, yes it can rid your home of spiders.  So if you’re dealing with a sudden spider surge as the weather cools, this fast DIY remedy might be your best first defense.

 

 Make Your Own Peppermint Spider Spray

This natural mix is easy to make, safe for most homes, and surprisingly effective at repelling spiders from your sleeping spaces, closets, cabinets, and basements, any dark space with spiders like to hide.

DIY Recipe:

• 6–10 drops peppermint essential oil 

• 1 teaspoon Dawn dish soap 

• 1 cup water 

• Shake well in spray bottle

How to Use:  Spray around windows, door frames, baseboards, under beds, and inside cabinets. Reapply every 3–5 days or after cleaning. Avoid spraying directly on pets or their bedding.

 

Why Peppermint Oil Works

Spiders “smell” and “taste” through their legs. The menthol in peppermint oil overwhelms their sensory receptors, making treated areas feel hostile and uninhabitable. While it doesn’t kill them, it strongly discourages nesting and movement.  Studies show peppermint oil is effective against spider mites and other crawling pests, and anecdotal evidence supports its use against common house spiders.  

Safety for Kids and Pets—Especially Cats

This mix is generally safe when diluted and used properly, but here’s what you need to know: Cats are sensitive to essential oils, especially in concentrated form. Never apply peppermint oil directly to their fur or bedding.  If you have cats remove them from the area you are spraying.  Let the peppermint dry before allowing cat back into the room .Use in well-ventilated areas and avoid spraying near litter boxes, food bowls, or sleeping zones. Store the spray out of reach of children and pets. Spot test surfaces

 Bonus Tip: Clean First, Spray Second

Before spraying, vacuum up webs, dust, and clutter. Spiders love quiet, undisturbed corners—so make them feel unwelcome. Then follow with your peppermint spray to seal the message. 

 Final Thoughts Not all spider bites are dangerous, but they’re never welcome. If you’re waking up itchy or spotting webs in your sanctuary spaces, don’t wait. This DIY peppermint spray is fast, effective, and safe when used with care. It’s one autumn ritual that protects your peace and your pets.
