I have seen a rat coming out from the manhole cover in my garden. They now appear to be nesting under my shed and visiting the bird table for food. I am terrified to go out into the garden in case they attack me. Please advise.

Your first priority is to repair the manhole. Rats live in the sewers but are more than happy to live on the surface if there is a comfortable place to live and a good source of food. Call us now and we will visit to eradicate the rats under your shed, but in the meantime stop feeding the birds as this will continue to provide the rats with an excellent source of food.
