The security alarm in the garage went off during the early hours of the morning last week. A right pain as both of us were deeply asleep and it happened three times in as many days. The alarm chap said the most likely cause was an insect had either crawled over it or flew past it. So after taking the car out today the missus set off some smoke bombs to kill anything that's in there.
She almost killed herself when setting them off in her mothers house a couple of years ago. She went back to one she forgot to light and got trapped in the smoke from another one.
