Attract Flea Beetle Predators
Having lots of birds on your property gives you a major army ready to keep the flea beetle population under control. Chickadees, purple finches, titmice, vireos, warblers, and toads all love to eat flea beetles or their pupae. At the same time, many beneficial insects found in a healthy landscape prey on flea beetles. These insect predators include spiders, ants, ground beetles, soldier bugs and parasitic critters such as techinid flies and braconid wasps.
