18 Insect-Repelling Plants for Your Garden

Companion planting is a common way to control pests naturally. It involves growing plants that repel insects together in order to achieve certain results, based on anecdotal data. As with humans, insects also have their favorite foods and find them by scent. Planting onions between cabbages will confuse the insects’ sense of smell. You won’t be planting in neat rows or large blocks of one vegetable. But it’s not necessary to do so.

Many of these plants are herbs and can serve two purposes. Deterrent plants can also attract beneficial insects that you want to have in your garden. Another type of companion plant that has proven to be very useful for gardeners is this one.
