Hundreds of people who live in seven villages in the southern Indian state of Tamil Nadu say they are reeling from an infestation of yellow crazy ants.
These insects, they say, attack their livestock and affect crop yields, putting their livelihoods in danger.
Yellow crazy ants are among the world’s worst invasive species, according to the International Union for Conservation of Nature.
They don’t bite or sting but spray formic acid, which can cause reactions.
