Every few years we seem to get rats in the loft, the bastards run between our house and the three connected. The council have been out numerous times to use prison to kill them but they can't seem to find the entry point therefore they keep returning..... Has any one had any experience of this and how they overcame it, I'm thinking of getting a loft company in to completely make the loft rat safe and to find any possible entrance that they may be finding..... Don't want a cat got two dogs!
