Thousands of locusts on the wall of a house at Cachipe Village, Moruga on Monday.

Fully grown locusts have started attacking crops in La Savanne, Moruga, as Insect Vector teams work assiduously to kill them before they lay their eggs.

Teams from the Forestry Division told Guardian Media that the insects have been spotted on the periphery of the La Savanne forests, where they are expected to reproduce.

Officials said the locust tracking teams usually follow the insects at this time of the year to map nesting grounds. These nesting areas are then sprayed to exterminate the pests.

“It is difficult to control them at this stage because they are flying in bands but once we track them, we are better able to control them before they decimate wide agricultural and residential areas,” the source said.

Locusts have been affecting residents and farmers in different areas in Moruga since February.

Thick swarms of hoppers stayed for weeks in Cachipe in Moruga, gnawing away at crops and fruit trees. On either side of Cachipe are vast forests where the hoppers are believed to have hatched in January.

One of the worse affected residents, Kiel Auguste, said the insects were becoming very prevalent in Moruga, disrupting outdoor life.

Residents in the communities were forced to use tape to block out the insects from entering through creases and holes and getting into their homes.

Officials from the ministry also reported that hoppers were seen and said to be prevalent at Point Coco and Granville in Cedros back in February as well.
