Keep caterpillars out of trees using sticky barrier bands
Late April is the time to put up sticky barrier bands
around your landscape trees. Immediately after hatching, gypsy moth caterpillars
disperse on silk threads and many will fall out of the trees. Barrier
bands will prevent caterpillars from returning to the trees and help reduce
damage from feeding. Directions on how to make
a sticky barrier band.
