The Ladykillers: Pest Detectives

A family facing the nightly terror of a bed-bug infestation calls in Imogen, who takes a scientific approach to pest control. Her research reveals what is making the modern bed bug a tougher menace to control than ever before, and she comes up with an ingenious solution to rid the long-suffering family of their parasitic intruders. Elsewhere a case of rats in a smart suburban street leads Deborah on a hunt to find whose garden is harbouring the pests, with surprising results. And a city farm has double trouble with pigeons and rats.

Imogen is called to one of the worst cases she has seen.

Bed bugs are on the rise in the UK, and Imogen witnesses one of the worst cases she's seen.

Cockroaches, mice, fleas and moths are in the firing line.
