Here are tips on how to identify, control, and get rid of cucumber beetles in the garden.
What are Cucumber Beetles?
If you find that the stems of your seedlings are being eaten off, leaves are yellowing and wilting, and holes are appearing, you may have a striped or spotted cucumber beetle problem. Cucumber beetles are found throughout North America and cause much of the same damage as flea beetles do. They are attracted to cucurbit vegetables, namely cucumbers, squash, pumpkins, and beans.
Often, the beetles leave their hibernating sites early in the season, and feed on seedlings right as they are emerging, usually killing them. The larvae feed on the roots of the host plants. Adults will also feed on the leaves, vines, and fruit of plants that survive, leaving deep marks in the rind.
Cucumber beetles hold another threat too: They can carry bacterial diseases and viruses from plant to plant, such as bacterial wilt and mosaic virus.
