Wow, are you in the top end of Australia??? We just had a G5 Mac do a flaming burnout because of the bloody ants! Have also seen them crawl out of the laptop. When I noticed it I quickly sprayed all around it and even sprayed on a papertowel and wiped down the laptop itself. Then put a DVD into it to play because that always heats it up, soon they came pouring out of the USB and power port. Now I just spray the desk top periodically, hate the smell, but is working so far.
