Help! My House is Infested, LifeStyle, 7.30pm

SARAH Beeny is out to help Brits with their vermin problems. The saddest case here is that of a woman named Tanya, whose house is so completely overrun with bedbugs that she and her five children sleep in the same room to try to keep away from them. Even after Beeny has the bugs killed with a heat treatment, more move in from a neighbour's house so it is back to square one. Other folks here are at their wits' end with rats, moths and foxes.

Tony Robinson's London Games Unearthed, History, 7.30pm

ACTOR Tony Robinson (Blackadder) has turned out to be a terrific documentary presenter, every bit as engaging as he is enthusiastic. Unfortunately, this documentary bites off a lot more than it can chew, or even needed to attempt chewing. Most of this year's Olympic events will take place in East London, so the idea is for the East London native, Robinson, to take us on a trip through the history of the area. That would have been fine in itself, but the documentary immediately widens its focus to take in the histories of the ancient Olympics and the modern Olympics, as well as stories from thousands of years of British history that don't always have a lot to do specifically with the East End. Still, there is plenty of interesting stuff here, particularly about the genesis of the modern Games.
