We've got those Japanese Beetles, the ones that look like lady bugs. A few always manage to get in the house. Last night one of them was in the blinds, which are aluminum. He make quite a little noise flapping his wings against those things. Twice in two days I walked into the kitchen and one of them fell off the ceiling and landed on my head. My hair must look like a nice place to set up ladybug housekeeping?
Odd you should mention that. My parents, who have several flowers and a garden in their backyard, had a LOT Of problems with Japanese Beetles over the summer, so they went and bought three of those bag/trap things. Dunno how the work exactly, but the beetles fly into the bag, and then fall into and are somehow unable to fly back up and out (chemicals in the bag maybe? Dunno.) Anyway, within just a few days TWO of the bags were nearly HALF FULL (we're talking LOTS of beetles here.)
