Locust attack: Why aren't we able to to end the crisis?

Farmers across the country are facing swarms of locusts ravaging their harvest. The attack of locusts began in western Rajasthan, where they arrived from across the Pakistan border. Farmers have started using sprays, banging utensils and using other loud noises to drive them away. But the locusts continue to be a major problem. At a time when Coronavirus and lockdown have already troubled the farmer enough, this locust attack has taken their troubles too far.
