- I was camping out at Glenreagh, NSW and found an insect in my bedding which I suspect was a native cockroach. It was very quick and impossible to catch and every time it felt threatened it sprayed a substance. At the time the substance was a little smelly, but not overly offensive. Two weeks later, my tent and hike pack reek. For some reason the smell reminds me of freshly brewed coffee, but with a nasty edge to it. Do you have any idea how to get rid of the smell, or will it just go with time? Any idea what the chemical/s are making the smell.
