🌿 8 plants that may help discourage pests
Some strongly scented plants contain compounds that may repel or discourage certain insects, but no plant will reliably keep an entire house free of mice, spiders and insects. Plants work best as a supplement to basic pest control.
- Peppermint — its strong aroma may discourage some insects; keep it in containers because it spreads aggressively.
- Lavender — fragrant and attractive to people, while its scent may deter some moths and insects.
- Rosemary — aromatic foliage that can help discourage some insects around outdoor areas.
- Basil — its scent may help reduce some flying insects around patios and windows.
- Mint — strong-smelling and potentially useful around entry areas; grow it in pots to contain it.
- Marigolds — commonly planted around vegetable gardens, although their pest-repelling effects are often overstated.
- Citronella-scented plants — may provide some mosquito-det to disappear simply because you grow mint or lavender. Reducing insects—their food source—and sealing cracks arounderring effect, but simply having a plant nearby isn’t equivalent to using a proven mosquito repellent.
- Catnip — contains compounds that can repel some insects, although it can attract cats.
🐭 What about mice and spiders?
This is where online claims often go too far. Planting peppermint or other herbs is not a reliable way to eliminate mice. For mice, sealing holes and gaps, removing food sources, and using appropriate traps are much more effective.
Spiders are also unlikely to disappear simply because you grow mint or lavender. Reducing insects—their food source—and sealing cracks around doors and windows generally works better.
Best approach: use plants for their fragrance and as a minor deterrent, but combine them with good sanitation, sealed food containers, and exclusion of pest entry points.
