Mice and Rat extermination and proofing in Cork
Rat control in Cork
What to know about Rat infestation?
Rats can squeeze through surprisingly small gaps — as little as 12mm (about half an inch). If an opening is slightly too small, they will often gnaw and enlarge it, leaving visible scratch and bite marks. Entry points often become greasy or dark from repeated contact with their fur.
While rats can enter above ground level, in County Cork homes the most common access routes are through damaged drains, sewer lines, and underground gaps. Rats are strong chewers and can cause serious damage, including:
- Contaminating insulation and storage areas
- Chewing through pipes and causing leaks or flooding
- Damaging electrical cables
Signs of a rat infestation
- Noises in the attic or walls (though heavy insulation can muffle sound)
- Droppings, often found in attics, under sinks, or hot presses
- Gnawed pipes, cables, or visible burrows near the foundation
Mice Control in Cork
What to know about a mice infestation
Mice typically enter properties through very small (5mm) gaps above ground level, including around doors, vents, and under pathways. Unlike rats, mice usually avoid sewer systems.
They may cause less damage to plumbing, but they are highly destructive to electrical wiring, which can increase the risk of fire — especially in older homes.
Signs of a mice infestation
- Chewed cables or small entry holes around the property
- Scratching or movement noises (often in attics or walls)
- Small droppings (similar in size to grains of rice)
Health Risks
Both rats and mice can carry diseases such as Leptospirosis (Weil’s disease), making fast action important to protect your home and family.
Extermination & Pest Proofing in Cork
At Pest Control Cork, we don’t just eliminate the problem — we make sure it doesn’t come back.
Many pest control treatments fail because entry points are left open, allowing reinfestation within days or weeks. Rodents leave behind scent trails and pheromones, which attract new rodents to the same locations.
That’s why we focus on complete pest control and proofing:
- Full extermination of the infestation
- Identification of all entry points
- Professional sealing and proofing work
We offer free sealing with all treatments wherever possible.
Over 95% of our customers remain rodent-free for years after treatment, thanks to our thorough approach.
