Yes. Suspend SC is labeled for Tent Caterpillars. Directly spray the plant foliage and nest. The larvae are usually easy to contact if spraying is done in late morning when the larvae congregate on the tent surface to warm in the sun. Mechanical control is also helpful with this pest. The egg masses are easy to spot after the leaves have dropped in the fall. Simply clip off and crush or drop into a bucket of soapy water.
