More than 560 suspected cases of rat infestation were reported to Dublin City Council over the last 18 months.
The Dublin 12 area saw the most reported cases with a combined 101 suspected infestations brought to the council's attention. Dublin 10 followed closely behind.
The Herald is reporting that most of the complaints came from Ballyfermot and Crumlin with residents reporting that the vermin had invaded their attics, bathrooms and back gardens.
In some cases homes required holes in ceilings walls and floors repaired in order to prevent rodent access.
Meanwhile it can also be revealed that the council has spent more than 22,000 euro successfully preventing pests from infesting its own HQ.
