Plants can provide a mild deterrent through their natural scents, but they won’t reliably eliminate an established infestation. For mice and insects, sealing entry points and removing food and standing water are usually much more effective.
-
Peppermint 🌿 — its strong menthol aroma may discourage some insects and rodents. Grow it in containers because it spreads aggressively.
-
Lavender 💜 — its fragrance may help deter moths, flies, and some other insects.
-
Basil 🌱 — its aromatic oils may discourage certain flies and mosquitoes.
-
Rosemary 🌿 — its strong scent can make an area less attractive to some insects.
-
Marigolds 🌼 — commonly planted around gardens and may help discourage certain garden pests.
-
Catnip 🌱 — contains nepetalactone, a compound with insect-repellent activity, including against some mosquitoes.
-
Lemongrass 🌾 — has a citrus-like aroma that may discourage some insects. Citronella products derived from related grasses have stronger evidence for mosquito repellency.
-
Sage 🌿 — its aromatic compounds may help make outdoor areas less appealing to some insects.
For mice and spiders
Don’t rely on plants alone. For mice, seal cracks and gaps, store food securely, and remove accessible food sources. For spiders, reducing insects—their food source—and sealing entry points is generally more effective than planting repellents.
Also check pet safety before bringing plants or concentrated essential oils into your home, because some can be harmful to cats and dogs.
