The Autumn Surge in Rodent Activity
As temperatures begin to drop in Ireland during autumn, rodents such as rats and mice begin seeking shelter indoors. Your home or business becomes a prime target for them to nest and find food. This seasonal surge in rodent activity poses health risks and potential property damage, making early prevention a crucial step.
Why Rats Are a Growing Concern
Rats are opportunistic creatures. With shorter days and colder nights, they naturally migrate closer to human environments. In Ireland, both the brown rat and the black rat are present, with the brown rat being the most common. They can carry harmful diseases like Weil’s disease, salmonella, and E. coli, which can be transmitted through contaminated surfaces, food, or even water sources.

Signs You May Have a Problem
Detecting rats early can save you from costly infestations. Common signs include droppings, gnaw marks, scratching noises, and greasy rub marks along skirting boards. A musky smell in hidden spaces is another red flag. Business owners should be particularly vigilant, as rat sightings can damage reputations quickly.

Preventing Rat Infestations
Prevention begins with sanitation and exclusion. Ensure bins are sealed, food is stored in airtight containers, and crumbs are cleaned promptly. Inspect buildings for entry points; rats can squeeze through small gaps the size of a coin. Sealing cracks, repairing broken vents, and installing door sweeps are simple but effective deterrents.
