I also notice that they are hard on the oaks and birch. So far, the maples seem fine.

In West Virginia there have been years in the past that the gypsy moths have been bad, many landowners had their forests sprayed, not maple producers, just folks trying to save the hardwoods for future timbering, we are in the Hardwood Alliance area. Some springs if it wet enough they catch a virus and die, I maybe wrong but I believe the spray had the virus in it? And before you ask I'm pretty sure the spray was invented in America! Not Wuhan China! Though it would be fun to ask Dr. Fauci what he knows about a virus killing Gypsy Moths.

The most common spray has a bacterium in it, Bacillus thuringiensis, more commonly known as BT. It is a naturally occurring bacteria found in soils. While BT itself is organic, it is generally mixed with an oil carrier (to make it disperse more evenly and stick to leaves). Caterpillars eat it and are killed. Doesn't help if they are past the feeding stage, so timing is important. When numbers get high, viruses and fungi (if it's wet) are typically responsible for population collapse.

They are eating just about every speice both hardwood and soft wood, the white oaks don't have aleaf left on them, red oak, rock oak are almost completly stripped, poplars, birch,beech and ash are abot 80% bare . The white pines are about 75% eaten they are now into the hemlocks, spruce and whie fir. No moths have appeared yet, this is much worse the infestation in the early 70's, that alot of rock oak around here.
