Are potato bugs defoliating your potato plants? Potato bugs can quickly become resistant to many insecticides. Instead of using chemicals try:
- Inspecting plants regularly. Shake any adult leaf beetles found on plants onto a drop cloth and transfer these to a container of soapy water.
- Attract natural predators such as spined soldier bugs, lady beetles, parasitic wasps, and tachinid flies.
- Apply parasitic nematodes to help control the larvae. Follow instructions carefully for storage and application procedures.
