Mosquitoes are the most dangerous animals on the planet. They spread diseases - malaria, dengue and zika – that kill huge numbers of people and cause suffering to many more.

So why not eradicate them?

It wouldn’t be easy. Scientists in Mali have found the mosquito is a surprisingly formidable foe, able to hide for months and evade capture. Other scientists are working on genetically-modifying mosquito populations so that they can’t breed.

But could releasing these re-modelled mosquitoes have unintended consequences? And might we accidentally destroy ecosystems by removing mosquitoes altogether? It turns out this tiny creature presents us with huge practical and ethical problems.
