Kerry County Council is investigating after insulation material from a commercial property found its way into a number of houses.
Residents in Páirc Chuimín, Kicummin had complained to the council after insulation beads appeared within the homes and gardens.
Residents have alleged that the insulation material came from a site owned by the developer Dunboy Construction.
The county council says the developer has undertaken to immediately carry out a clean up of the site and says its environment department will monitor the clean up.
Dunboy Construction has made no comment to Radio Kerry.
However in an email seen by Radio Kerry, the director of the company, Barth O’Neill writes to resident Ramona Keogh in which he says they have investigated the issues, identified the problem and apologised unreservedly.
Mr O’Neill says the company can and will fix the problem immediately.
Ramona Keogh sent Radio Kerry photographs showing scores of insulation beads in her home and garden, including her baby’s room.
She also claims the material, which she says is airborne, can make its way into houses even though doors and windows are shut.
