A swarm of desert locust is migrating from Yemen and Somaliland to the eastern part of Ethiopia, officials told BBC Afaan Oromoo.
Groups of locusts has been spotted in five different regions of Ethiopia including Oromia, Amhara, Afar and Somali.
The swarm are adults which, unlike adolescent locusts, do not damage vegetation, Ethiopia's Agriculture Minister Zabdiyos Solat told the BBC.
But they bring their own dangers.
Mature swarms are searching for a conducive environment to lay eggs which itself could bring significant damage to crops.
The government plans to start spraying chemicals in Afar region, where the locusts are feared to be laying eggs, on Friday.
