The 10,000 residents of the town of Envira are fighting back with poison and boiling water as well as mounting a campaign to clean up garbage, but the ants keep spreading, said the mayor, Luiz Andrade Neto. 'They attack small animals, like chickens and cats and turtles, and children who don't have defences. They go after meat, after salt, and blood.'
Mr Neto said the ants had been identified as a species of fire ant. About 70 per cent of the town had been invaded, with low ant-hills every one to five yards.Reuse content
