Ladybugs suck at killing ALL of the aphids. Only the ones that lays eggs actually eat them. It’s there larvae that will eat the shit out of them. I didn’t research them well enough before I bought them. I still have some aphids, after 2.5 months of ladybugs, on an populated that I almost wiped out, before ladybugs were introduced. Just started spraying the aphids with NukeEm. Doesn’t seem to bother the ladybugs but kills the aphids.
I use them for thrips inside grow and outside tent for mites and thrips. They do good for that. The do not like spider mites to much but if they are there they will eat them. Good to know about the aphids thanks for the info.
