The Asian ladybug is an ecological disaster, and I have no mercy on them.

I am not fond of the Asian ones, either, as they not only bite but they actually eat the fruit. The native ones do neither.
Interestingly enough, for many years, we had the Asian lady bugs everywhere (farmers were using them on the soybean fields) but, lately, I have been seeing the little red-spotted ones once more. Last spring, I ordered some of the native lady bugs and all summer, I found plenty for the rest of the summer (I usually don't find many after a few weeks). I wonder if pesticides are killing off the Asian lady bugs but allowing the natives to live as the natives don't usually munch on the fruit like the Asian ones do?
