Desert locusts on Friday evening entered Embu County, bringing the number of counties invaded by the disastrous pests to 11.
Other counties that have been invaded by the locusts include Isiolo, Samburu, Wajir, Garissa, Marsabit, Laikipia, Mandera, Kitui, Baringo and Turkana.
The pests in Embu County were seen eating shrubs, millet and green pastures.
Mbeere South Deputy Commissioner Charles Igiha said the swarms had moved in from Kitui County through Isako. According to Igiha, the Agriculture Ministry was already aware, however, he urged them to treat the matter with seriousness.
"Locusts are a menace. They should be eliminated before they wreak havoc on farms," noted Igiha.
Residents have been urged to monitor the movements of the pest. The residents expressed fear of the expected damage if instant measures are not be applied.
"The locusts are spreading very fast and are many. We are worried because they are feeding on trees and grass for our animals," said one of the concerned villagers.
Kiambere MCA Lenny Mwaniki termed the invasion disastrous, calling upon a quick action by the government.
"The locusts are destroying all plants. They should be controlled before they clear everything," said Mwaniki, warning of an impending famine.
Agriculture PS Hamadi Boga confessed that the government is struggling to fight the invasion, because of the limited resources available.
He added that only five aircraft were being used for the spraying exercise, while four others for surveillance. Food and Agriculture Organization (FAO) has already warned that the situation will lead to famine if the government doesn't act speedily.
The organisation has also hinted that the menace might not be ending any time soon.
