Hi all, my girlfriend and I moved to a small farm last year that we're gradually tidying up and renovating. One of our old barns that we're tidying up shows signs of rats getting in where they've chewed through boards at the base that used to be doors to let the birds that were being raised there out. We're replacing the boards with corrugated metal sheet as the rest of the barn is made of that. We've seen the odd rat about but not done anything about it yet and now it's time to fix the issue.
I can take the .22 or air rifle out some evenings after putting down a cat food bait but I'm often away with work and am looking at getting a couple of traps that my girlfriend can use when I'm away. Fenn traps seem to be the thing but which size would you recommend? We don't want to use poison as we've a lot of owls round us and I was reading about the number of owls dying from eating poisoned rats.
Would something like 8" drain pipe be a suitable tunnel to put the trap in and how long should the tunnel be? We've a bunch of old pipe around the place so making tunnels is easy. I plan to put one along either edge of the barn where the rats run, probably with cat food bait.
Thanks for the advice.
