This is the third year in our 25 here that we have had a load of rats, each time when a nearby farm was doing some major disturbance or building project. All of us around get the resulting rat exodus from that one farm.
What they come for with us is the wild bird feeders - they are fearless. This time I first realised we had an invasion when I saw 10 young rats, various ages, feeding under the seed feeders, like a pulsating rug. We put poison in our attic, because with double stone walls rats easily get up there, and it's well away from pets and livestock. Most of the rats have disappeared now. However, I know they are also living in a den right under the barn - impossible to get to - and in some drainage pipes, which might be easier to at least block off.
I hate using poison but sometimes it's necessary. The sad thing is that I really like rats - I would happily have a pet rat living in my pocket, they are friendly and intelligent and so interesting. We tried shooting them but with poor success.
There seem to be a lot of reports of rats coming out of hiding this year and being seen in domestic environments where they are usually not found.
The obvious answer for us, once the main numbers are cleareed, is to stop feeding the wild birds, but I really don't want to do that. The feeders allow for a lot of spillage and I'm trying to find a solution to that. We have stopped the rats from climbing the feeder poles, but ideas for catching fallen seeds, grain and fat block peckings are all impractical.
Our new dogs are totally hopeless with rats. Sophie caught one when she first arrived, but seemed to drop it in surprise, and now they perhaps think that rats are in the same category as livestock and are not to be caught.
So, no, you're not alone.
