How to Identify and Get Rid of Squash Bugs
“Squash bugs are the bane of a gardener’s existence! They are very difficult to kill and cause havoc. These bugs inject a toxin into the plant and suck the sap right out of it. The leaves will wilt, dry up, turn black, crisp, and brittle. Smaller plants will die.
The squash bug is fairly large (over 1/2-inch long) with a brownish body and flat back. If you squash them, they will stink. They overwinter in your dead leaves, vines, under boards, and even in buildings. They fly to the plants as soon as vines start forming to mate and they lay egg masses on the undersides of the leaves.”
