hey. weve got em in ny. they re ruining alota hemis.there are several things you can do to attempt "control" of the little buggers.

dont hang feeders on or near-birds may transmit larvea
water well in time of drought
remove heavily infected branches
remove heavily infected trees {they become resivoirs for adelgids}
DONT fertilize with nitrogen{you could have many times more if you do so}
oils and soaps help but you have to drench entire tree, even the top.
periods of freezing and thawing deplete populations

the wierd thing with them is that they are a sexual. the female lays a couple hundred eggs. the nymph forms transfrom into either winged or wingless adults. the winged ones die after searching for a type of spruce thats not found over here. the wingless ones keep the cycle going.

trees can die in 4 yrs or they can hang on for many. obviously if there are other factors that are working against your tree it makes it harder for your tree to survive

i wonder if there is a way to alter their offspring so that they only hatch winged larvea.
