We have two savvy rats skiddling around our coops during broad daylight. i go outside a hundred times a day to find them sitting inside the duck's food bin eating (and pooping and peeing). So i am constantly setting the food bin up, then down again so the ducks can eat. i have set snap traps inside the duck pen after i lock them in their coop at night. i have tried shooting them with a pellet gun, but i'm a terrible shot and the pellets will ricochet if i hit something solid - so scared for my chickens and ducks. i have set out a rat zapper and also another larger one, to no avail. So i think i need to step up to poison. Here is what i'm thinking of getting: http://www.pestmall.com/protecta-rats-bait-stations.html It's a bait station that you can lock, and you can also put one of those large black plastic snap traps inside. i was going to use Tom Cat bait blocks, which you can secure inside. From what i have read, they are the least toxic to any secondary poisoning. The main ingredient is Bromethalin. The rats seem to be coming from under our shed, which is set on uneven ground so has pillars on the backside, for easy rat access. i was going to get two bait stations and set them under the shed where none of my animals can access. We do have a neighbor cat who is over here a lot looking at the rats, but he is way too slow to catch them. He looks well-fed so i doubt he would try to eat a dead rat . . . at least i hope not. Does this sound like a plan? Any other suggestions?
