The poor ladybugs, when they arrive at my house, they do not know this but they are on a kamikaze mission. I set up some netting around my plants and I let those bugs loose. My hopes are that they eat every last aphid and spider mite that is currently feasting on my plants. Once the aphids and mites are gone, the ladybugs do not have more to eat. I do nothing to keep them alive. They eventually meet their end belly up on the cement floor, hopefully within the netting. Because of this, I cannot concern myself with what happens to their larva. I personally hope they do not produce larva.
