Top 20 Plants for Pest Control

Mint’s pungent aroma deters ants, rodents, and insect pests. Plant mint around garden borders or entry points to repel unwanted visitors. Different mint varieties like peppermint and spearmint work equally well.

4. Marigolds

Marigolds are a must for organic vegetable gardens. They repel nematodes plus insect pests like cabbage worms, thrips, and even rabbits. The scent comes from their roots, so interplant marigolds throughout your vegetable beds.

5. Chrysanthemums

Chrysanthemum plants produce pyrethrum, a compound used in many insect repellents. Their pungent odor drives away roaches, ants, ticks, lice, spider mites, and more. Use potted mums as natural pest control indoors or out.

6. Petunias

Petunias emit a sticky substance on their surfaces that traps and incapacitates small insects like aphids, leafhoppers, and squash bugs. This makes petunias a smart companion plant for vegetable gardens.

7. Nasturtiums

Planting nasturtiums repels whiteflies, squash bugs, aphids, and more pests that prey on vegetable plants. The peppery-scented flowers and foliage act as a great trap crop to lure bugs away.

Interplanting radishes repels cucumber beetles, rust flies, and other soil pests from gardens. The spicy smell deters insects before they can munch on your crops.

9. Chives

Chives naturally discourage aphids, Japanese beetles, and carrot root flies through their powerful onion scent. Plant a few chive plants throughout your vegetable garden for easy pest prevention.

10. Garlic

Like other alliums, garlic is highly effective at warding off destructive pests such as borers, spider mites, aphids, and even voles and deer. Interplant garlic throughout veggie beds or create garlic borders.

The woodsy, robust aroma of sage serves as a powerful insect deterrent in the garden. This hardy herb repels cabbage moths, carrot flies, mosquitoes, and more. Grow sage plants around vegetable patches or use dried sage to make sachets for deterring pantry moths.

15. Thyme

Thyme’s tiny leaves pack a pungent punch that ants, beetles, and even mice find offensive. This low-growing herb works well as a garden edging or ground cover to create a pest barrier. The strong, minty scent helps thyme repel whiteflies and cabbage worms too.

16. Basil

The strong licorice-like smell of basil effectively drives away flies, mosquitoes, and salt marsh caterpillars. Planting different basil varieties like lemon basil intensifies the repellent effect. Use basil as a garden companion for repelling pests from tomatoes, peppers and more.

While irresistible to cats, the nepetalactone in catnip is highly offensive to many insects like mosquitoes, termites, cockroaches, and squash bugs. Plant some catnip as a repellent around gardens, in pots, or use dry leaves as a natural insect repellent.

20. Pennyroyal

A member of the mint family, pennyroyal has been used for centuries as a potent pest repellent. Its strong scent drives away mosquitoes, gnats, ticks, fleas, and even mice and rats. Grow pennyroyal around foundations or paths to establish a pest barrier.Copy
