There are a huge number of plants that can be eaten by flea beetle, and it partly depends on which different species of flea beetle are found in your area. Common victims include beans, eggplant, evening primrose or sundrops, potatoes, and sunflowers.

We regularly fight off the beasties on our Brussels Sprouts! As they are so small it's best to control them chemically with a spray evey 10 days.
