I've had a couple in the house, one before xmas and the other a couple of years ago. The earlier one was similar in size to the one pictured. It avoided all traps for two weeks, after too many sleepless nights (it ran round in the loft at night, noisy bugger) I had to put poison down - that did the job but I then had a dead rotting rat somewhere in the house :shock: After a few days I managed to track the smell (!) to the bedroom floor - pulled up some floor boards and there he was wedged in a load of pipes and wires. The smell was unreal (had to wrap a tea towel around my face), first attempt to grab him by the tail resulted in the skin peeling off it (gag!) - so I had to reach in and grab the very squishy body (gag again) and wiggle it free from the wires without it bursting...
The one before xmas was here for revenge for the death of his brother :wink: , he was trapped in the kitchen for a week and couldnt get anywhere else. We pulled our knackered kitchen apart twice looking for him and couldnt find him (now the kitchen is really knackered), one hour after we had cleaned and refitted everything I was talking to no skills 19.5 and opening the draw in the sink cabinet - out of the corner of my eye I saw a strange thick bit of brown string waving about, opened the draw further and turned to look in... and yes the ******* was hanging off the back of the draw box, scared the fecking life out of me!
Got him with a trap a few days later, during the aftermath I discovered that he had eaten a complete pouch of rat poision from the back of the cupboard, to no apparent ill affect. Ironicaly it was from the same box that I'd used to poison his brother with years earlier..
