Flea beetle control
Flea beetles are primarily pests of vegetable crops, but they can also significantly damage seedlings during the propagation process. They are very tiny and when disturbed, they jump like fleas. Watermelon, pumpkins, peas, beans, eggplant, sweet potatoes, beets, spinach, and potatoes are other typical hosts.
Flea beetles are most active in the spring after overwintering as adults either underground or in plant detritus.The larvae feed on fresh roots where they might impede the growth of seedlings after the eggs are laid by the adults. The larvae then pupate and become adults, ready to eat and lay eggs. The adults chew small holes in leaves which give leaves a sieve like appearance. Typically, there are one to two generations every year.
Use general predators to monitor and detect infestations early. When using beneficial insects for natural organic pest control it is a good practice to be preventative.
What works best for Flea Beetles?...
HB Beneficial Nematodes - Will attack the larvae and prevent them from becoming adults.
Other alternatives to beneficial insects that can be used to control Flea Beetles include:
Flea Beetle Trap Kit - The scented lure and the color of the trap attract adult flea beetles. Upon landing beetles stick to the non-toxic, adhesive surface.
To stop Flea Beetles from feeding, apply Surround WP (kaolin clay) to the surfaces of the plants. These products will both offer a physical barrier as well as insecticidal qualities when Flea Beetles come in contact with them.
BotaniGard Maxx & other B. bassiana sprays infect and kill adult flea beetles.
