What are Squash Bugs

Squash bugs are one of the most devastating pests that can affect a squash plant, pumpkins, cucumbers and watermelons. The adult bugs are about 1/2 inch long, dark brown or black in color, and have a flat, oval-shaped body. They lay their eggs on the underside of squash leaves, and the nymphs that hatch are bright yellow or green with black stripes. These nymphs mature into adults within 4-6 weeks, and can quickly lay hundreds of eggs. Squash bugs feed on the sap of squash plants, causing the plants to wilt and die. In addition, they can transmit a number of plant diseases. To control squash bugs, it is important to inspect your plants regularly and remove any egg masses that you find. You can also trap adults by placing boards or pieces of cardboard around your squash plants. The bugs will congregate under the boards at night, making them easy to collect and dispose of in the morning. How do you know if your plants have squash bug damage?
