8 Plants That Help Repel Mice, Spiders & Other Insects
Certain plants contain strong-smelling essential oils or compounds that may help make your home and garden less attractive to some pests. While plants alone rarely provide complete pest control, they can be a useful part of a broader prevention strategy.
-
Peppermint 🌿
Its strong menthol scent may discourage mice, ants, spiders, and some other insects. Grow it in containers near doors, windows, or patios. -
Lavender 💜
Lavender has a pleasant fragrance for people but may help deter mosquitoes, flies, and moths. Place pots near sunny windows or outdoor seating areas. -
Basil 🌱
The aromatic oils in basil may help discourage mosquitoes and flies. Keep pots near windows or in outdoor areas where people gather. -
Rosemary 🌿
Rosemary’s strong aroma can help make outdoor areas less appealing to certain insects. It also grows well in warm, sunny conditions. -
Marigolds 🌼
Marigolds are popular companion plants because their scent may discourage some insects. Plant them around vegetable gardens, walkways, or patios. -
Catnip 🍃
Catnip contains nepetalactone, a compound that has demonstrated insect-repelling properties, particularly against mosquitoes. Keep in mind that it can attract cats. -
Chrysanthemums 🌸
Chrysanthemums naturally contain pyrethrins, compounds used in some insect-control products. Growing them may contribute to a less insect-friendly garden, although they aren’t a substitute for targeted pest control. -
Mint 🌿
Mint’s strong scent may discourage ants and some insects. Like peppermint, it spreads aggressively, so growing it in containers can help prevent it from taking over your garden.
A useful tip
Plants can help discourage pests, but they generally won’t eliminate an established infestation. For mice, sealing holes and removing food sources is usually more effective. For insects and spiders, reducing clutter, fixing screens, and eliminating standing water can make a bigger difference than plants alone.
