Ha! A mate of mine threw baits around the roof thinking the rats would die outside, how horribly wrong he was. I think he ended up collecting 7 stinking rats from his roof. And I did warn him.Get up in there and drop the smelly chunt into a zip bag.
While you are up in there, throw a load of blocks of rat bait around. Might as well have them all stinking at once. Hopefully they fekk off outside to die anyway.
