Ornamental Plants for the Most Common Pests

Managing pests organically in the garden is the safest way to keep your vegetables safe from problems while also keeping your family safe from harsh chemicals and pesticides. The best way to solve pest control problems naturally is by using companion plants to repel the most common pests. The best pest repellants are strong smelling herbs like garlic, but there are also many ornamental plants you can use to control the most common pests.


Marigolds are probably the most well known pest control flowers in the United States. They've been used for hundreds of years as pest repellents and different varieties will help control different types of pests. French marigolds will kill root nematodes, but Mexican marigolds are your best choice for repelling the widest variety of common pests in the garden. Marigolds also attract beneficial insects to the garden, including wasps, ladybeetles, snails and lacewings.


Lavender is a beautiful bush that blooms colorful blossoms in a variety of blue to purple colors and puts off a strong sweet scent that attracts many beneficial insects to your garden. This attraction is its strongest benefit because those insects will feed on the ones you don't want around. Lavender is also an excellent repellent for moths, mosquitoes and fleas.


Petunias are a colorful flower that make a great ornamental pest control companion to any garden. They're an excellent companion plant for tomatoes, but scatter them throughout the garden to repel leafhoppers, certain types of aphids, asparagus beetles and other general garden pests.


Sunflowers are the top choice for taking care of aphid and ant problems. The ants will actually "herd" aphids to the sunflowers and the flowers are tough enough to hardly even notice them. The seeds from sunflowers are treats for birds, including hummingbirds, who will eat whiteflies.

Sweet Alyssum

Sweet Alyssum is a compact, easy-to-grow herb that makes a wonderful groundcover to attract hoverflies and bees. The hoverfly larva eat aphids and the bees help pollinate fruit trees and other plants or flowers.
