Pilots should regularly check to see if new hatchings of locusts have occurred in other regions or if infestations have spread.

Locusts can fly up to 3000 feet and can be in swarms of up to 50 million, while individual swarms can range over tens or even hundreds of kilometres.

The insects are also active at night, travelling hundreds of kilometres in the right conditions.
