MINOR? Come on over to my place, park your car and have lunch on my patio or deck or just sit out under (or even close to) one of the hundreds of oaks surrounding my house just to enjoy the weather. THEN tell me how minor this problem is.
The d@mn things (and their nasty disgusting POOP) completely cover my house, cars, trailers, trucks, barn etc. etc. My vehichles look like they're covered in tobacco juice and maggots. Every surface is completely covered in seething, writhing caterpillers and caterpiller shiat. I have to wipe off every door handle before i think of touching it anywhere.
I've been watching them on the property for several years and each succeeding year they've gotten worse. There is absolutely no reason they won't get even worse next year. We have hundreds and of oaks surrounding our house - not a leaf in sight. I have no roses, no crepe myrtle, no poppies no nothing - while the trees might come back (maybe in July) the crepes and roses are already dead. This hasn't been the environment for just a few days or even a week - it's been like this for THREE weeks and there's another two or three weeks left. They've eaten absolutely everything. Their poop dropping from the trees sounds like misting rain 24 hours a day.
DUDE......Come on over and Monitor my hundreds if not thousands of trees which are
hundreds of feet tall "to determine if control is necessary". Then YOU tell ME how 'minor' this is and how it can be taken care of without intervention. Nothing in the link that you posted says this is something "minor" nor does it tell me how to "control" them considering the forestry guy even took pictures. He's never seen these things so bad in all the years he's been watching them.
Minor?.....
yeah RIIIIGHT nothing "minor" about this mess.
