A French company is taking an unusual approach to tackling one of Europe's most troublesome insects: breeding millions of tiger mosquitoes and releasing them into the wild.
At its facility in Montpellier, Terratis currently produces around 1.5 million sterile male tiger mosquitoes every week. The insects are released in neighbourhoods where residents face growing problems from the invasive species, which can transmit diseases such as dengue, Zika and chikungunya.
