On May 23, 2019, the District Magistrate of Jaisalmer issued directives to the Locust Control Office to take effective control measures to address the issue of locusts. On the evening of May 23, the Locust Control Office staff acted swiftly and sprayed chemical pesticides in the above said area. If any such chemically-killed locusts are eaten by GIBs, they can die due to poisoning, which would be a catastrophic event. the GIBs are already on the verge of extinction.
