In Kenya, police facing the country's largest outbreak in 70 years have fired machine guns and tear gas into swarms in an effort to prevent them from consuming fields. Ethiopia is spraying pesticide from small planes to displace hovering throngs, though swarms have forced passenger jets in the region to make emergency landings.
