If you've started hearing scratching noises in the walls, noticing strange smells, or finding droppings around your home, you may be dealing with a rat infestation. In Dublin, rat problems are becoming increasingly common due to dense housing areas, ongoing construction, and easy access to food sources in residential neighbourhoods.
The earlier you spot the warning signs, the easier it is to stop a small rodent issue from turning into a serious infestation. Rats multiply quickly, spread disease, damage property, and can become a major health hazard for your family. In this guide, we cover the most common signs of a rat infestation in Dublin homes and the exact steps you should take next.
