We lost a couple of hemlocks this year which are on our property line and a screen thus leaving an unattractive hole.

I first thought it was just due to snow damage over the past couple of winters and then I saw it: the accursed wolly agelid.

The question is if I shear these very overgrown trees will it get rid of the agelids for this year (and wait to spray until '08) or should I just have the tree guy spray them now?

Thanks, ML
