First real plum season this year after I killed off a ant colony farming aphids under my plum tree. :-) Edit: Used boiling water to take out the nest, then sprinkled a mix of potato starch with fine ground sugar around. I don't want to much poison on and around my fruit trees. And yes: up to 6 ladybugs had a party in that tree for three consecutive days. I read somewhere that each of them can munch up to 100 aphids a day so I guess there was quite a few to start with.
