A city in India is dealing with a plague of locusts.

A desert locust invasion got so bad in Gurugram, a satellite city of New Delhi, that officials told residents Saturday to close their windows and bang utensils to discourage the swarms of pests, Reuters reported.

Pilots at Delhi’s international airport, which is close by Gurugram — where some of the world’s top corporations are headquartered — were told to take extra precautions when taking off and landing because of the grasshopper-like critters.

India’s locust outbreak is one of the worst in decades. Officials have broken out specialist vehicles, fire engines and helicopters to spray insecticides in at least seven populous states in the north, center and west of the country.
