I called them up because I spotted a rodent in my flat. Their service is amazing: they sent someone round the same afternoon that I called. Unfortunately, at the end of the visit, I realised that I ended up paying £107 for someone to analyze the droppings, tell me it was not a rat (thankfully), place some food poison on the floor and leave, all in 15 minutes. I actually believed that by calling an exterminator in, I'd be immediately free of the rodent. So, even though their office admin is impressive and efficient, and the man they sent out very charming, just go to the internet and read about rodents, then go to the store, buy a trap and wait. The end result will be the same and you'll be £107 richer for it.
