Oh alright, I guess I'll give it a rest, too.
Now that the snow has mostly melted I can see the brown rats I tried to eradicate with traps last year had a prosperous winter. Tunnels under the snow and grass throughout the raised beds, fruit trees, and cedars. Under the shed too.
No obvious food source - chicken feed is in a galvanized bin. Compost pile has been limited to coffee and coop waste for the past 7 months. Bastards ate a bunch of my carrots last Fall. Hoping they haven't hit my garlic yet. I'd cry.
No sign of them within 15 yards of my coop or run. Keeping them from free ranging until the migratory waterfowl have mostly passes, anyway, but I don't need them interacting with rats.
Tried trapping and baiting (equal parts sugar, Cornmeal, baking soda) last Fall and it made a dent, but it doesn't matter now - they've taken over.
I think my only option is bait stations as far away from the run as possible.
Unless anyone else here has had success using a different method.
