Argentina is facing a plague of locusts. Officials say it's the worst invasion the country has seen in 50 years.

That part of Argentina is important for agriculture, and many are worried about the economic impact of the swarm.

The government is trying to control the outbreak before it gets worse by fumigating young locusts.

But officials say at this point, they can't stop the plague; they can only try to reduce the damage.
