Look on a map of North America and  Hamilton is the only Canadian city to have spotted the nasty brown marmorated stink bug.

But there are fears that could change.

The native of Asia has been found in a number of U-S states and there are now concerns it could spread throughout Southern Ontario.

The small, brown, hardshelled bug is the size of a thumb nail and it gives off a nasty odour, a mix of burnt rubber, rotten cheese and
cilantro

It's also a voracious eater, munching on both fruits and vegtables which could put Southern Ontario's agricultural industry at risk.

An entomologist with the  U-S Department of Agriculture says the pest is an incredible hitchhiker and this is the time of the year it
is on the move.
