The neighborhood cat, Jazz, and our dog Cookie, are both severely lacking in their ability to eradicate these pests so I've got to try something else. I took the compost bin apart and found no rats in it, but now Cookie digs in the pile and makes a mess. New plan: I found
hungryowl.org and they have nesting boxes and nesting box plans for those that don't live in the bay area. I found their information very interesting and helpful. According to the Hungry Owl Project, if the male owl finds the nesting box in the winter he will coax his female to join him and make a nest in the box. A single barn owl can consume 3,000 rodents in a 4-month breeding cycle. Wow, I don't think I have that many rats, but I do have gophers and moles and voles I think and I'm sure my neighbors have plenty as well. In the meantime I am going to have to get some traps TODAY since this plan won't materialize until next winter and I can't have these rats destroying anything else.
I won't use D-con, although I have in the past; it's awful to watch these animals suffer and then there is the huge problem of these weakened animals easily getting captured and eaten by all of the local wildlife, including owls, who then are poisoned as well. Hopefully I can find a good trap.
