If you are heading somewhere tropical this summer, or just want to protect yourself from bites in your own back garden, then which mosquito repellents can you trust?

Greg Foot gets up close and personal with a box full of hungry mosquitoes to find out.

Is it all about DEET or are there alternatives which are just as effective? What about citronella? And how well do bracelets, patches and candles perform?

And if you do get bitten, what is the best treatment for a mosquito bite?

Greg assesses the scientific evidence with Professor James Logan from the London School of Hygiene and Tropical Medicine and Dr Jane Wilcock, an indepedent researcher and GP.
