What's the best - and most humane - way to get rid of pests?

For some of us Tom and Jerry might be the sum total of our knowledge of the struggle between domestic life and unwanted rodents. But for listeners Colin and Mary, things are getting much more real! Colin wants to know if the plug-in devices he's seen that promise to deter rats and mice using ultrasonic actually work. Mary has caught mice and then released them back into the wild in nearby woodland, believing it's the more humane way to deal with the problem. But is it?

With the help of Natalie Bungay from the British Pest Control Association and Rob Young, Professor of Wildlife Conservation at the University of Salford, Greg Foot sets out to find the answers, hoping to nibble at the metaphorical cheese without getting caught in the figurative trap (or something).

All of the ideas for our investigations come from you, our listeners, and we're always on the lookout for more.
