Hickory Nut Tree Has Tent Caterpillars

Question From: D. Sendell - GEORGIA
Q: My hickory nut tree is 40 ft tall and I fight these pests every year (tent catapilllars) . I cannot spray that high. Is there anything systemic I can use?

A: You need to enlist the services of a professional - a certified arborist. To find one in your area go to www.TCIA.org and enter your zip code. Best Nancy
