I remembered something sort of related to the CITES problem. 8 years ago my wife went back to the Philippines for a few weeks to visit family. When she returned one of her souvenir's was a small flag. The flag stick was a piece of reed of some type about 2' long. A few months later I was at a window and saw a small beetle I'd never seen before crawling on the sill. Then realized there were dozen's. It was the middle of winter so I knew they had not come from outside. Tracked them down to the piece of reed. It was riddled with holes and beetles were still crawling out. Funny that sealed orchid flasks are inspected for hitchhikers but that came in without suspicion.
