The US has reportedly drawn up plans to breed billions of flies over Mexico in an attempt to eradicate a vicious variety of flesh-eating maggot.

The move comes as the New World Screwworm fly larvae continues to cause chaos as it infiltrates the US beef industry, affecting wider wildlife, pets and, in rare cases, humans.

According to scientists, the new batches of male sterilised maggots will be dumped over the South American nation and the US state of Texas in a bid to eradicate the vicious variety of flesh-eating larvae.

The US Department of Agriculture is said the male flies, which measure slightly larger than the average housefly, will be sterilised with radiation before being released.

The strategy, set out by scientists, will force the female screwworms to breed with the newly sterilised males.

The flesh-eating variety of the screwworm maggots were eradicated from the US in 1966, but the creatures appear to me making a comeback.

    I read something different re: the cause.

    It’s difficult to say how they made it past the Darien Gap, but there are several possibilities, Earl said. Monitoring and surveillance for screwworm was relaxed due to the COVID-19 pandemic several years ago, and an increase in illegal cattle trafficking in the region might also be helping to spread animals infected with maggots. The increase in human migration northward may also be playing a role, Earl said.
