Bugs destroying peach tree
We have a small peach tree in our yard. Last year was fine and produced lots of great fruit. This year its COVERED in some weird, small (about the size of a pea) orange with black spot insects. I say insects, they are almost like snails, they don't seem to be moving at all but are on the actual branches in groups of maybe 10 or 20, all over the tree. At first they looked like some kind of ladybug. Maybe they aren't even insects but some kind of fungal growth? We admit to knowing very little about trees and gardening :)
The leaves are starting to blister and turn red too. We saw the same thing on a neighbors tree so I guess its common around here (San Francisco bay area).
Can anyone tell us what these are and how to get rid of them?
