In Summary
  • The unfamiliar insects manifest signs of the human bot fly which is native to Central and South America.
  • The fly is not known to transmit disease-causing pathogens
  • But the larvae of  Dermatobia hominis will infest the skin of mammals and live througout the larval stage in the subcutaneous layer. 
  • The flies have extended to the neighbouring areas of Mukuyu and Mumbi.

Residents of Kandundu village of Kiharu Constituency in Murang’a County have expressed concerns over bites by strange flies which then leave eggs on their skins that then hatch into larvae.

They say the flies come from the Gatogi dumpsite which is some 200 metres from their homes and that their bites leave them in painful agony.

Apart from the residents, livestock and other domestic animals are also under siege from the insects.

Mr Mwangi Kuria, a victim, said after he was bitten by the insect, he developed itches characterised by excessive pain before he developed a boil from the bite.

A few days later, his son removed nine worms (larvae) from his hands and backside.

He said when the insects were removed, the pain faded away and he slept for the first time since he was bitten.


“I developed swellings on the affected areas and felt a lot of pain when the larva was being removed but the pain faded away and my health returned to normal,” Mr Kuria told the Nation on Thursday.

His wife Phyllis Waithira now keeps a broom handy to sweep away the increasing insects that now live with them.

She called on the county and national governments to relocate the dumpsite or spray the garbage to reduce the infestation of the parasites that now have them fearing an outbreak of diseases.

Ann Mwangi and her two children are also victims of the strange insects.

Her children aged three months and two years have also been bitten by the insects.
