🌿 8 Plants That May Help Deter Mice, Spiders & Insects
Some aromatic plants contain compounds that may discourage certain pests, but no plant can reliably make mice, spiders, or insects disappear. They’re best used alongside good sanitation and sealing entry points.
- Peppermint 🌱 — Its strong menthol scent may discourage some insects and rodents. Grow it in containers because it spreads quickly.
- Lavender 💜 — Its fragrance may help deter some moths and other insects while attracting pollinators.
- Rosemary 🌿 — Its aromatic oils can make it less attractive to some insects.
- Basil 🌱 — Its strong scent may help around outdoor sitting or garden areas.
- Marigolds 🌼 — Commonly planted around gardens because their scent and natural compounds may discourage some pests.
- Mint 🌿 — Another strongly scented option, although it can become invasive if planted directly in the ground.
- Catnip 🌿 — Contains nepetalactone, a compound with demonstrated insect-repellent activity.
- Lemongrass 🍋 — Its citrus aroma may be unpleasant to some insects, although simply growing the plant isn’t equivalent to using a concentrated repellent.
🐭 For mice and spiders, don’t rely on plants alone
For mice, sealing cracks and holes, storing food securely, and removing nesting materials are generally much more effective than plants.
For spiders, reducing insects around the home and sealing gaps around doors and windows can reduce the food and shelter that attract them.
Bottom line: These plants can be useful additions to a garden, but claims that placing a few plants around your house will eliminate mice, spiders, or mosquitoes are exaggerated.
