I had rats in my loft last year.Pest control were very good,he did what he had to,put some bait down.It's a council property,they can charge now for pest control,but I didn't have to pay,as my neighbours had ,and still have,a lot of rubbish on their garden.They admitted that they had seen rats there,but just laughed about it.My problem is that pest control man said he needed to check their loft too,and also the back of their propery,as there may be an entry point there.But they refused to let him do anything,the housing officer was refused entry too.They have learning difficulties and disabilities,so they can't be upset,but it didn't matter that I was terrified.They are animal lovers too,so am I,but there are times when you have to be cruel,dealing with rats in the loft is one of them
