[UK] Bedbugs: Luton Council receives 'alarming number' of calls

I never had bedbugs or even seen them but when i traveled through Australia, people were terrified if you just mentioned bedbugs. A guy i met gave me his bedbug spray when he left. I read on it that the spray doesn't poison them, it had micropic glas shards or something in it that would just cut them into pieces. I found that pretty metal

Fire. And/Or chlorine gas.
