Home Remedies for Spiders: Peppermint, Vinegar and Reality

Peppermint and vinegar sprays are often recommended for spiders. The evidence is thin.

The short answer

Peppermint oil and vinegar may deter spiders briefly where sprayed, but there is little reliable evidence of lasting effect, and the smell fades. Essential oils can harm cats and other pets, so use with care. Better results come from removing webs and egg sacs, reducing insects, decluttering and sealing gaps.

What they may do

• Brief deterrence on treated surfaces.
• Cleaning effect for vinegar.

Limits and safety

• Effect fades quickly.
• Essential oils can be harmful to cats and other pets.
• Vinegar can damage some surfaces.

What works better

1. Remove webs and egg sacs.
2. Reduce insect food.
3. Seal gaps and declutter.
4. Use professional help for heavy cases.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
