Professional, reliable and friendly, The Exterminating Angels is a family-owned pest control business in North London run by brothers Tony and Steve Angel.

However, The Exterminating Angels is a pest control business with a twist - the pests they deal with range from verbally-abusive pigeons, and stroppy squirrels who communicate their issues with life via Morse code. In the surreal but deadpan world of The Exterminating Angels the pests talk, they argue, get drunk and 'have issues', just like the rest of us.

Each episode, The Exterminating Angels are called by an irate householder with a problem pest. Tony and Steve remain professional and resourceful, even though sibling tensions sometimes result in needless bickering. They also live together with their ageing Italian Mother which doesn't help.
