Oh my gosh Rob... I live in dread of that happening.. I just started seeing them about a week ago, and put out a couple traps. In just a weeks time, I've notice a big increase... Perhaps with the ground being so cracked from the drought, they have more habitat... I really hate them.
Tom, if I had known it was that easy to get an import permit, I would have been ordering plants willy-nilly from all corners or the world for decades. Thankfully, I'm much more sensible now..
