8 Plants That May Help Repel Mice, Spiders & Other Insects 🌿
Some plants have strong aromas that may discourage certain insects, but it’s important to keep expectations realistic. No plant reliably eliminates a pest infestation, and evidence for repelling mice or spiders simply by growing a plant is limited.
-
Peppermint — its strong menthol aroma may discourage some insects and rodents.
-
Lavender — its fragrance can be unpleasant to certain moths and insects.
-
Rosemary — contains aromatic compounds that may deter some insects.
-
Basil — its strong scent may help discourage certain flying insects.
-
Mint — aromatic foliage can be useful around outdoor areas.
-
Marigolds — commonly grown around gardens and may discourage some insects.
-
Catnip — contains nepetalactone, a compound with demonstrated insect-repellent properties.
-
Sage — its aromatic oils may discourage some insects, particularly outdoors.
🐭 For mice, do more than plant herbs
If mice are entering your home, the most effective steps are to seal cracks and openings, remove accessible food, store food in sealed containers, and address nesting areas. A pot of peppermint isn’t a substitute for these measures.
For spiders, reducing insects around the house, removing webs, and sealing gaps around windows and doors can help.
⚠️ Pet safety matters: Some plants and concentrated essential oils can be harmful to cats, dogs, and other animals. Check the specific plant’s toxicity before bringing it into a home with pets.
