As spring arrives and temperatures begin to rise across Ireland, homeowners may notice increased activity—not just in their gardens but also in the unseen corners of their properties. That’s because April marks a critical turning point in rodent behaviour, especially for rats and mice.
Warmer weather encourages these pests to move, breed, and seek new food sources. Without proper prevention and control, even a small rodent issue can escalate into a costly infestation. Here’s why April is such an important month for rodent control—and what you can do to protect your property.
The Spring Shift in Rodent Behaviour
During the colder winter months, rats and mice tend to stay hidden in secure, sheltered locations—often inside homes, sheds, garages, and commercial buildings. As spring begins, their behaviour changes in key ways:
- Breeding season begins: Rodents start reproducing rapidly in April. A single female rat can produce up to 60 offspring a year.
- Searching for food: As natural food sources become more available outdoors, rodents may become more active and adventurous in their foraging.
- Shifting nesting spots: Some rodents may move to more suitable nesting areas, potentially closer to or inside your home.
In short, spring is when small rodent populations can quickly become serious problems.
Common Signs of Rodent Activity in April
Rodents are excellent at staying out of sight—but they often leave signs of their presence. Be on the lookout for:
- Droppings (small, dark pellets) in cupboards, attics, or behind appliances
- Gnaw marks on wood, cables, packaging, or plastic
- Scratching or scurrying sounds, especially at night, in walls or ceilings
- Grease marks along walls or skirting boards from repeated movement
- Shredded materials, like paper or insulation, used for nesting
If you notice any of these, it’s a good time to act quickly.
Rodent Season: Why April Is Key for Rat & Mouse Control
Why April Rodent Infestations Are So Dangerous
1. Rapid Breeding
Rodents are prolific breeders, and spring is when their reproductive cycle kicks into high gear. One pair of mice can lead to hundreds of offspring in just a few months if conditions are favourable.
2. Health Risks
Rodents can carry a range of diseases such as leptospirosis (Weil’s disease), salmonella, and hantavirus. These can be transmitted to humans through droppings, urine, or contaminated food and surfaces.
3. Property Damage
Mice and rats are notorious gnawers. They can chew through insulation, wiring (posing fire risks), and even pipes. The damage they cause often goes unnoticed until it becomes costly to repair.
How to Protect Your Property This Spring
Taking preventative steps in April can help reduce the risk of a full infestation later in the year. Here’s how to make your home or business less appealing to rodents:
1. Seal Entry Points
Rodents can squeeze through incredibly small spaces—mice need just a 6mm gap to enter.
- Inspect foundations, vents, and door frames for gaps or holes
- Seal cracks with wire wool, steel mesh, or expanding foam
- Install bristle strips under doors to block access
2. Eliminate Food Sources
Rats and mice are opportunistic feeders. Don’t make your property an easy target:
- Store food (including pet food) in airtight containers
- Clean up crumbs, spills, and bins regularly
- Avoid leaving bird seed or compost uncovered outside
3. Tidy Up Outdoors
Rodents love hiding in overgrown areas and clutter:
- Trim back hedges, shrubs, and long grass
- Clear away wood piles, rubbish, and unused equipment
- Ensure outdoor bins are tightly sealed and not overflowing
