Forget harsh chemical sprays and costly exterminators—there’s a powerful pest repellent hiding in your medicine cabinet right now. That little jar of mentholated ointment you use for colds and sore muscles? It’s a natural, multi-purpose bug and rodent deterrent that works like magic.
Packed with strong-scented ingredients like menthol, camphor, eucalyptus oil, and cedar leaf oil, this ointment overwhelms the senses of common household pests, keeping them far away from your home. Below are 13 brilliant, practical uses to turn this ordinary balm into your new favorite natural pest control trick.
🦟 1. Keep Mosquitoes at Bay
Rub a small dab of the ointment on pulse points—like your ankles, wrists, neck, and behind the ears. The intense scent creates an invisible shield that mosquitoes can’t stand.
Bonus Tip: Leave open jars of the ointment near windows, under beds, or by doors to ward off mosquitoes indoors.
🪰 2. Banish House Flies
Flies buzzing around your kitchen? Try this:
- Smear the ointment onto small cloth strips or paper and place them near trash cans and sinks.
- Leave open jars of ointment in fly-prone zones.
- Mix a tiny amount into warm water in a bowl and let it sit out—the rising vapors will help drive flies away.
🐜 3. Block Ant Trails
Ants hate menthol and camphor. Identify their entry points—around windows, doors, or cracks—and apply the ointment directly with a cotton swab or your finger.
Also rub:
- Around the base of trash bins
- Along kitchen counters or near pantry areas
- Directly on active ant trails to confuse their scent trail
🕷 4. Repel Spiders
Don’t want spiders setting up camp in your corners?
- Rub ointment around windowsills, baseboards, and doorways.
- If you find webs, apply the ointment nearby to discourage spiders from returning.
🪳 5. Send Cockroaches Packing
Cockroaches follow scent trails—disrupt them with menthol:
- Rub it around pantry shelves (not directly on food), near pet dishes, and trash cans.
- Apply to areas where you’ve spotted cockroach activity to help deter others.
🐀 6. Deter Rodents Naturally
Rats and mice loathe strong scents like menthol and eucalyptus.
- Soak cotton balls in the ointment and place them behind appliances, inside cabinets, or along baseboards.
- Refresh them every few days to maintain the smell barrier.
🦟 7. Soothe and Protect Against Gnats
Thanks to its cedar leaf oil, this ointment also keeps gnats away.
- Dab on your wrists, ankles, and neck when outdoors.
- Already bitten? Use it to soothe itchiness naturally.
🛏 8. Fight Bed Bugs
Create a scent barrier bed bugs won’t want to cross:
- Apply the ointment around mattress seams, bed legs, and cracks in bed frames.
- Reapply weekly for lasting protection.
🪳 9. Repel Silverfish from Bathrooms
Silverfish thrive in moist environments like bathrooms.
- Mix 1 teaspoon of ointment with 1 liter of hot water, pour it into a spray bottle, and lightly mist under sinks, behind toilets, and inside cabinets.
🧺 10. Protect Your Clothes from Moths
Avoid using chemical mothballs. Instead:
- Rub a small amount on cotton balls and tuck them into drawers, closets, or storage bins.
- Refresh every couple of weeks to keep the scent strong.
🪲 11. Keep Beetles Out
Beetles often sneak in through small crevices.
- Apply ointment around windowsills, doors, and wall cracks weekly to keep them from entering.
🌿 12. Protect Garden Plants from Earwigs
Don’t want bugs munching on your flowers?
- Rub the ointment on plant stems or wooden stakes in your garden.
- The smell deters earwigs and other pesky intruders—no chemicals needed.
🐝 13. Stop Wasps from Nesting
Wasps avoid strong smells like menthol.
- Apply the ointment to porch railings, patio furniture, under eaves, and window frames.
- Reapply after rain or cleaning to maintain its repellent power.
🐾 Bonus: Help Keep Fleas Off Pets (Safely)
Never apply directly to your pet’s skin, but you can:
- Rub a small amount onto their collar
- Dab onto bedding corners or rugs near where they sleep
- Keep their areas clean and vacuumed to boost effectiveness

While mentholated ointments are generally safe for external use, follow these precautions:
- Do not ingest or use on broken skin
- Avoid contact with eyes and mucous membranes
- Not recommended for children under 2
- Keep away from pets and wash your hands after use
