Attracting Beneficial Insects

Attracting Beneficial Insects

Predator insects offer a natural alternative to pesticides. The listed plants will help deter pests and attract natural predators. A mix of these plants provides habitat and alternative food sources many predators require. Predator insects and parasites remain on certain host plants so avoid pesticides. When your plantings mature you’ll be able to observe the “Good Guys’ at work.
