8 Plants That May Help Repel Mice, Spiders & Other Insects 🌿
Some plants have strong natural aromas that may discourage certain insects and other pests. However, plants alone aren’t a reliable way to eliminate an infestation. Sealing entry points, removing food sources, and keeping areas clean are usually much more effective.
1. Peppermint 🌱
Peppermint’s strong menthol scent is commonly used in homemade pest-deterrent strategies. Grow it in a pot near windows, doors, or outdoor areas. Keep it contained because mint can spread quickly.
2. Lavender 💜
Lavender has a powerful fragrance that some insects may avoid. Place containers near sunny windows, patios, or entrances.
3. Basil 🌿
Basil’s aromatic oils may discourage certain flying insects. Keep a pot near a sunny kitchen window or doorway and enjoy the herb for cooking as well.
4. Rosemary
Rosemary produces a strong herbal aroma and can be grown in sunny outdoor locations. It may help make certain areas less attractive to some insects.
5. Lemongrass 🍋
Lemongrass has a citrusy scent and contains citronella-related compounds. It’s a popular choice for outdoor spaces, although simply growing the plant isn’t equivalent to using a tested insect repellent.
6. Marigolds 🌼
Marigolds are often planted around gardens because their aroma may discourage certain garden pests. They’re also easy to grow and add bright color.
7. Catnip
Catnip contains nepetalactone, a compound that has demonstrated insect-repellent activity. One downside: it can attract cats, so consider where you plant it.
8. Mint
Mint’s strong scent may discourage some insects. Like peppermint, it grows aggressively, so a container is usually the easiest way to control it.
What About Mice and Spiders?
This is where expectations matter. There isn’t good evidence that simply placing these plants around your home will reliably drive mice or spiders away.
For mice, focus on sealing holes and gaps, storing food securely, and removing accessible sources of food and water. For spiders and insects, repairing screens, sealing cracks, reducing clutter, and eliminating standing water can be more effective.
The bottom line
Use fragrant plants as a supplementary measure, not your primary pest-control method. A clean home, sealed entry points, and removal of food and water sources will generally do much more to keep unwanted pests away.
