I found rats particularly smart when it comes to traps, however, he is old and probably quite bold now the cats gone. We can hire live traps which you bait with peanut butter. Once they are in the trap you put them in water and drown them or be creative with a pipe and cars petrol exhaust fumes. Not inside your garage of course!
I am only being brave on here. I have just bought expensive bait that only effects rats. I cannot bare the thought of accidentally killing anything else in a flow on effect.
Good luck!
Hi, what is the bait called?
Cheers
