Up to 5/8" long. When newly hatched, squash bugs have reddish heads and legs and green bodies. Later, heads and legs turn black, and bodies turn light to dark gray. They suck sap from leaves of all vine crops. During early part of growing season, vine crops are easily killed.
Early detection is important because full-grown squash bugs are difficult to kill. Kaolin clay suppresses the pests. Start prior to infestation; apply every 5-7 days, with the first two applications 3 days apart. We recommend Surround At Home Crop Protectant. With only one generation per year, squash bugs can be greatly reduced by keeping squash vines covered with Super-Light Insect Barriers until blossoming begins.
