Ordered 50 larvae + 30 free, but when I opened the case and singularly put them on individual plants, I had no more than 30 that were alive. There were lots of small black pieces left so they'd either eaten each other or there wasn’t 80 in there to begin with. Also, when I did put them next to the black aphids, I’d say no more than 5 of that 30 actually ate them, and there’s still a large number of aphids around the garden so the reason for buying them hasn’t worked. The only positive I can give is there is an increased number of ladybirds around the garden which is a pleasant sight. Sorry green gardener, but it’s a 2/5 from me.
