Squash Bugs: Identification and Control

True to their name, squash bugs target cucurbits—especially winter squash and pumpkins. Adults are dark brown to black, almond-shaped, and about ½ inch long. They pierce leaves and fruit, sucking sap and causing wilting.

Life Cycle & Monitoring

In spring, females lay clusters of hard, brown eggs on leaf undersides—scout and destroy them. Adults shelter under flat objects at night; place boards in the evening, then flip them in the morning to collect and dispatch the bugs (they emit a foul odor when crushed).

Chemical Control

For adult infestations, carbaryl is an option. Always follow label instructions.
