Some plants contain strong-smelling compounds that may discourage certain pests, but no plant reliably keeps mice, spiders, and all insects away. Plants work best as a supplement to sealing entry points and keeping food sources inaccessible.
8 plants commonly used as natural pest deterrents 🌿

Peppermint — its strong scent may discourage some insects and rodents.
-
Lavender — commonly used around windows and outdoor areas to deter certain insects.
-
Rosemary — its aromatic oils can help discourage some insects.
-

-
Mint — strong-smelling foliage may be unpleasant to some pests.
-
Marigolds — can provide some insect-repellent effects, although results vary considerably.

For mice and spiders
Plants alone are unlikely to control an established mouse or spider problem. For mice, seal holes and gaps, store food in closed containers, and remove accessible food sources. For spiders, reducing other insects—their food supply—and sealing entry points can be more effective than relying on plants.
Also remember that essential oils are much more concentrated than the plants themselves and can be irritating or toxic to pets, particularly cats and dogs.
If you tell me whether your main problem is mice, spiders, mosquitoes, flies, or cockroaches, I can suggest the most practical non-toxic approach for that specific pest.
