First off -
why are you yelling???Â
Â
Dude, patience is in order, amongst other things. You just got the shipment yesterday. The ones that are alive need a period of rest from their travels, and also a drink of much-needed water. Give them a few days to a couple weeks before writing them off.Â
Â
Half are dead? Most orders start at a few hundred ladybugs. Consider this: Just a few ladybugs (like 10) can wipe out a teaming aphid infestation within a couple of weeks. When the aphids are gone, so is the ladybugs' food supply - by ordering ladybugs at this time of year, in a way you are ultimately killing them by starvation. Oh, they'll take agave nectar diluted with water for a while, but chances are very slim they'll survive more than a handful of weeks after the aphids (or other) are gone. In a way, the fact that half arrived dead is a good thing, as you likely don't have enough pests to feed all of the ladybugs that came in your order.Â
Â
Even if you order parasitic wasps at this point, they arrive in eggs and you have to wait until they hatch. By the time that happens, the ladybugs may have solved the problem. Note, however, if you got the ladybugs from a less-than-reliable dealer, they may not work. I got ladybugs from Hirts the first year, then found others on this site didn't have good experiences with them. Nor did I - they are clearly raised in captivity and fed in a manner that they don't have to hunt. A good vendor knows how to raise them hunting, or captures them wild.
