After desert locusts invaded her farm in central Kenya, Mary Muthoni, 61, ran around her corn fields shouting and banging on an old iron sheet in a desperate attempt to drive them away.
"They came here yesterday evening and sat on top of these trees as though to rest there for the night," said the mother of seven, who lives in Mahiga-Meru village in Laikipia County.
"This morning, they decided to come down on my maize farm and started eating it, destroying the maize in the cobs and also the leaves," she said last month.
