caterpillars in a sac in apple tree
Much to my horror I discoverd cobweb like "sacs" of caterpillars and
their small black eggs in my apple tree. I live in Denmark but have only
come across the phenomenom in my childhood in the UK. I remember one
summer in the mid 80's that a warning came on the news about sacs of
caterpillars that could cause an allergic reaction if touched. They hung
in sacs on trees and I remember we had a tree like thsi ion our front
garden.
The question is how do I get rid of them as they seem to be slowly
eating away at both the leaves and the small fruits on my apple tree?
