What plants keep bugs away?

I’d like to try some natural pest control methods. Does basil repel bugs, and what plants keep bugs away?

Certain herbs and plants are often promoted as natural bug repellents, but what plants repel bugs? In reality, not many. While basil, dill, mint, and rosemary contain aromatic oils that some insects find unpleasant, these plants alone won't protect your home or yard from pests. At best, they may provide minimal, temporary deterrent effects in very small areas, but they're not a substitute for effective pest control.

Common herbs and their limitations

• Basil contains compounds like eugenol that may deter flies and mosquitoes, but only when the leaves are crushed or the oils are concentrated. A potted basil plant won't keep bugs away from your patio.
• Mint has a strong scent that might discourage ants and mosquitoes in immediate proximity, but it won't prevent infestations. In fact, mint spreads aggressively and can become a garden problem itself.
• Rosemary may repel certain beetles and mosquitoes when its oils are released through crushing or burning, but the living plant offers very limited protection.
• Dill has aromatic properties that some claim deter aphids and spider mites, though evidence of effectiveness is largely anecdotal.
• Other plants like lavender and marigolds are similarly overstated as pest repellents. None provides reliable, long-term bug control.
