Apple tree problem

I have numerous apple trees that are becoming covered with what looks like ashes. If you kind of rub at it it does come off but it is covering all off the tree. It also spreads over the buds. Seems to almost suffocate the tree branches until they dry out and become brittle and break. It prevents any good fruit from developing and is spreading threw several trees. I try to be diligent with my spraying and nothing is helping. I need suggestions so we do not lose our entire orchard.

Bugs that look like white rice

For months I’ve been seeing bugs that look like white rice. They are every where in my home. Along with bugs that look like black pepper. My cloths are getting holes, they are in my pantry, refrigerator. On my tile floors I’m finding a clear liquid that sparkles. I’ve had two exterminator come out, they say it’s nothing. However, they didn’t bother to check the attic, my furniture, rugs. When they walk in they see a clean home. Which is why I think they don’t bother to check thoroughly. My husband thinks I’m crazy. Problem has gotten so bad I wish no longer to live here.
