My sister in law has just sent me a text from her home in Cantal where she is on holiday and she has a problem with rats which she needs your advice with. She said there are two nests (according to a neighbour) in a bank at the bottom of her garden. She enjoys her gardening but now can not stand to go in the garden because of her rat phobia. What is the best way to eliminate this pest and ensuring they don't come back. Local knowledge I think is invaluable in cases like this.
