I suppose we're fortunate because out of the million trees on our property only one or two have a presense of brown tail moth caterpillers.  I've read up on them and boy, they sound like they can really contaminate the air with their air en-masse.  So I figured time for a pest control person but I'm told that they won't do anything now because it's too late.  I have one Oak tree in particular that is about 60' high which seems to be getting the brunt of these pests.  Is there anything I can do or anyone I could call to hit this one particular tree.  Further south in Connecticut we had a Gypsy Moth problem and the state hit it from the air with a biological that killed the caterpillers that was inert to us and our animals.  Isn't there something that would do the same for us here?  I'm in Mid-Coastal Maine.

Are you sure they are brown tail? Only asking because regular tent caterpillars seem to be abundant and are harmless by comparison

Ya know, that's a good point.  I didn't realize that "regular" tent catapillers are present, too.  I'lll check.  Thanks!

My dad has been complaining about it and warning me over and over.  Figure they will be gone by mid July.
