gypsy moth tent on oak tree?
Very concerned to see what looks like may be a gypsy moth tent on the end of a branch on my northern oak tree at the curb. Just yesterday driving in the gorge I saw a HUGE infestation of the same thing on all the trees lining I-84. This tree is essential to our home. What can I do about the tent? Will it spread and destroy my tree? Please inform me ASAP what steps I should take, if any. Thanks.
