Why is my tree dying

[GW11]

I think you were right......
I went back out after reading some of the comments this time with my glasses on and I think you are right. Looks like there are lots of them on it.
I see a lot of what looks like cluster of droppings. (at least I think they are droppings)... Is there anything I can do or is this tree going to be done.

Could be... I was going to mention, they don't have the big "tent style" nests like the tent caterpillars.

Hopefully the tree is ok.

Looks like Gypsy moth to me. Treatment is similar to that of spruce budworm. Spray with Bt (baccillus thuringiensis) to kill caterpillars. You can also spray and kill cateripllars with soap and water. Do this every other day if you have to. If you have other trees nearby, this includes your neighbor too, spray them as well. If this is your first year experiencing them and you take preventive measures right away the tree should survive. If you ignore the problem they will re-occur next spring and that will finish off the trees permanently.
Unlike spruce budworm that prefers jackpine and spruce, gypsy moths usually go after broad leaved species first then attack coniferous species when all else is gone.

Would dawn dish soap and water combo work

Spray it with some Diazinon and prune out the dead branches. will be good as new by fall of 2022.

I don't think that is available in Canada, could be wrong but google says it is not available here. I will try the dawn soap and water thing tomorrow and see how that goes

When I had the spider mites, I asked the guy at the nursery about spraying with soapy water….he said all I would get was clean bugs !!!! Lol

You have to have a license now, but if you know someone involved in agriculture (Farming), Golf Courses, Orchards. We use to use in it in lawn lawn and tree care for aphids in trees and grubs in the turf, but it was banned for lawn care and non commercial uses..

I get it from friends if I need it.

What, I dont want to clean up those dirty buggers, I will look for something that will kill them maybe that BTK...

Dawn is good,but,Sunlight is better because it has a higher acidic content that insects absolutely detest. It works for caterpillars and ants and parasites that affect Red Maples,Norway Crimson King Maples with bark wounds. I had a new inetrlocking patio built last year. This year,the ants were all over it. Last Friday,I spray it with soapy water giving it a good soaking. Today,they aren't anywhere to be seen.

Certainly will, I was going through up to four gallons a day killing them on the foundation and on trees and on my shed. I have a blue spruce and another fir tree that they are attacking now that they've defoliated the oak and basswood on my property. If you can, get the Dawn Ultra 2x or 3x or the newest 4x that I bought today. You want a good blue tinge to the spray. Just be sure to rinse off the plants with water after or it will burn the leaves, not sure about needles on fir trees. The best way to prevent them from climbing trees is to wrap duct tape around the trunk and smear it with vaseline, they will not cross that barrier. In fact it will concentrate them under the duct tape so you can kill them all in one shot. I think I posted the pic on that other thread.
