I would also recommmend Roger from Critter Solutions. He was extremely helpful from the off and came round within a couple of hours of my call to investigate some loud noises coming from our eaves. It seems it was just a bird rather than a squirrel as I'd feared. He blocked up the hole where the bird was getting in and, even better, he didn't charge as it was a quick and simple job. A really nice man who struck me as being very knowledgable and trustworthy.
