The beetles are small and shiny, vary in color from black to tan or spotted, with large rear legs. Beetle larvae feed on the roots of the plants and the adults feed on the foliage leaving holes in the leaves. Flea beetles don’t usually kill established plants, however, they can spread diseases, such as wilt and blight from plant to plant. Row covers may be successful at keeping these beetles out—they should be used immediately after transplanting so these pests are not able to infect the plant. An “Old Farmers Almanac” recipe¹ for a homemade spray of 2 parts rubbing alcohol, 5 parts water, and 1 tablespoon liquid soap sprayed on the foliage may deter the flea beetle.
