We had numerous pest companies in due to a rat issue we were experiencing for around 1 year (they were getting under the floorboards and keeping us up at night). None of them were able to resolve the issue and one company even said thats what you have to deal with if you live in London. Pestology provided a survey and completed the works shortly after and so far so good (I have waiting 4 months before posting this). I wouldn’t hesitate to recommend these guys, especially considering how much we wasted on the alternatives which end up being a total waste of money.
