Wait, I was mistaken...its the Japanese Beetles that are toxic although I had ducklings eating them this year and they were okay.
When you squash Asian Lady Beetles they have a nasty smell and oddly I've never seen wild birds eat them when they swarm in the fall. They must taste really bad.
You might want to consider traps.
ALB come in our house ever fall and we suck them up with hand held vacuum.
