I can't speak from experience but I've been told they can bite pretty hard if you mess with them.
I have been told - by an agricultural professional - that Asian lady bird beetles "DO NOT BITE!". Perhaps they don't bite like spiders or mosquitoes do, but in my experience every time they land on me they take a nibble to see if I'm edible or not. There is no bite mark or redness, but they do nibble just that once. By that time, I've felt the "non-bite" and brushed the beetle off so it can land and nibble again.
Like native lady bugs, these beetles are useful against aphids and other soft-bodied arthropods. Unlike the natives, around here these beetles 'swarm' in the fall when the soybeans are harvested, making working or walking without bugs flying into every exposed body part impossible. They also hibernate in any crack or crevasse - a real bane for those in old farm houses - stink if crushed, exude a stain if frightened, and leave poop stains on lamps, walls, curtains, etc.
I abide by the live and let live philosophy as long as they aren't too much of a bother. I've even hired a few from my neighbor's old farmhouse in mid winter to clean up the aphids trying to take over my sun room. Not my favorite insect, but certainly useful to area farmers.
