Claims that illegal dumping is causing rat infestation are to be investigated by Dublin City Council.
The issue was raised by Independent councillor Anne Quigley during a meeting of the Central Area Committee which was discussing how to deal with large scale illegal dumping of household waste on the streets in the North city centre.
The council had suggested leaving illegal waste for up to five days but this was opposed by local residents
Senior executive officer with the city council Brendan Hayden said all residents are being written to and being asked to prove how they dispose of waste and which company they use.
Council tenants are required to do this as part of their tenancy agreement while private households are also legally obliged under the Waste Management Act.
The council's Evironmental Health Officers who are visiting multi-rental units particularly in the North Circular Road area to check compliance with housing regulations are also asking landlords to show waste storage areas.
And the council will also be carrying out a poster campaign in a number of litter blackspots in the North City area.
