Residents of a Dublin 15 estate say they hope the latest works will finally solve a long-running problem of rodent sightings in the area.

In July, the Riverwood Residents Association appealed to residents to report any sightings of rodents.

Writing on the Residents Association website, they said: “A few residents have reported seeing rats in their back gardens and in the public areas of the estate.

“We have a contact in Fingal County Council that deals with vermin in the county.

“Before we meet him we need to get information about the extent of the problem.

“If you have seen a rat on your property or elsewhere in the estate please let us know.

“We will use this information to help identify the areas to concentrate new eradication efforts.”

The group subsequently received reports of rats seen in Riverwood Copse, Riverwood Chase, Riverwood Glebe, Riverwood Heath and Riverwood Lawn.

Following a visit from a representative from the HSE Pest Control Unit, it was determined that the rats were most likely in the sewer pipes.

Last week, the Residents Association confirmed that Fingal County Council and Irish Water would commence work to clean out the sewers, which they hope will lead to a dramatic decrease in the number of rats on the estate.

This is not the first time that the area has had problems with rats.

In July 2014, the Residents Association received multiple reports of rats being seen in various places in the estate.

On that occasion the HSE Pest Control Section treated the drains throughout the estate and set rat poison traps in three locations on the open space area in Riverwood Chase.

Commenting on the latest sightings, a spokesperson for Irish Water said: “Irish Water is working with Fingal County Council to investigate a rodent complaint in an estate in Dublin 15.

“The sewers have been checked and baited and it is planned to carry out a CCTV camera survey to see if there are any defects in the pipes, misconnections or incorrectly finished manholes which would provide an entry route for rodents.”
