Have just remembered another cocky incident.
Asleep in the bedroom of a holiday apartment in the French Alps, I awoke during the night to find several of the little darlings on and in our bed - one crawling over my husband's hand.
First thing next morning we stormed off to the letting agent who, in a very gallic manner just shrugged and said we were imagining it.
Well, you don't mess with us, so next night we harvested the liitle and not so little blighters (including one running round the seal of the 'fridge where it was trying to work out a way to get in!).
We took our jar of beasties back to the agent the following morning and politely reiterated our story. Another gallic shrug, we were imagining the whole thing......
At this point we emptied our jar on to the countertop in their office. As I said, you don't mess with us!
We were 'rehoused' within a few hours!
Incidentally, there was a very musty smell in the problem apartment and we now know what it was, so if you are on holiday and smell an odd unusual musty smell, check in the middle if the night that you don't have any unexpected guests!
