Did you know there could be up to 120 million rats in the UK right now? That’s nearly two rats for every person in the country.

What’s more, these unwanted guests aren’t just passing visitors. When rats under floorboards make themselves at home, they can squeeze through gaps as small as 15mm and dig up to 18 inches underground to access your house. However, the real concern isn’t just their presence – it’s their remarkable reproduction rate. A single female rat can produce up to 200 babies in a year, with each litter containing 6-8 offspring every six weeks.

The consequences can be severe. From gnawing on electrical cables that could cause fires to leaving droppings that spread diseases like Leptospirosis and Salmonella, these rodents pose serious risks to both your property and health. If you’re hearing scratching under floorboards at night or noticing other signs of rats, it’s crucial to act quickly.

In this guide, we’ll show you exactly how to identify, tackle, and prevent rat infestations under your floorboards, ensuring your home stays safe and rat-free.

Signs of Rats Under Your Floorboards

Spotting signs of rats under floorboards early allows for quick action against these unwanted guests. From distinctive noises to visible evidence, here’s how to identify a rat infestation beneath your feet.

Scratching noises at night

Since rats are nocturnal creatures, the most common indicator of their presence is the sound they make after dark. These rodents create soft scratching and rustling noises as they move around under floorboards. Additionally, you might hear gnawing sounds as rats work to keep their continuously growing teeth sharp.

The scratching typically becomes more noticeable in specific areas, particularly along walls connecting to neighbouring properties. While banging on the floor might seem like a solution to silence them, rats often continue their activities undeterred.

Rat droppings and urine marks

Rat droppings serve as a clear indicator of infestation. These dark, cylindrical pellets measure between 1-2 cm in length, resembling large grains of rice. A single rat can produce between 20 to 50 droppings within 24 hours. Fresh droppings appear dark and shiny with a soft texture, whilst older ones become hard and crumbly.

Along with droppings, rats leave distinctive urine trails that:

• Produce a strong ammonia-like smell
• May fluoresce under UV light
• Often appear alongside dark grease marks from their bodies

Gnaw marks on wood

Rats must constantly gnaw to maintain their ever-growing incisors. Their teeth marks, measuring approximately 1/8-inch long, can be found on:

• Wooden beams and floorboards
• Electrical cables and wiring
• Water pipes and utility lines

These gnaw marks pose serious risks beyond property damage. Chewed electrical wiring can lead to fire hazards, whilst damaged pipes might cause flooding. Furthermore, rats often take advantage of existing gaps around pipework to access living spaces.

The presence of dark smears along walls and corners provides additional evidence of rat activity. Due to their poor eyesight, rats tend to run alongside walls, leaving greasy marks from their bodies. These rub marks, combined with other signs, help identify frequently used rat pathways through your property.

Regular inspection for these signs, particularly in less-used areas of buildings where foot and tail marks might be visible in dust, can help catch an infestation before it grows. Since rats can burrow up to five metres beneath the ground, though typically only half a metre, they can easily access the space beneath floorboards through various entry points.

Understanding How Rats Enter

Rats possess remarkable abilities to infiltrate homes through the tiniest openings. These clever rodents can squeeze through holes as small as 15mm, making it challenging to spot potential entry points.

Common entry points

Several vulnerable areas around your property serve as gateways for rats to access the space beneath floorboards:

• Poorly Fitted Pipes and Utility Lines: Gaps around exterior pipes and utility openings create easy access routes. Rats often exploit spaces where builders have left openings around service lines.
• Air Vents: Both modern and older properties face risks through air vents. Whilst original clay airbricks erode over time, modern plastic vents prove equally vulnerable as rats can gnaw through them.
• Foundation Issues: Natural cracks in foundations, especially in older buildings, provide direct access. Once inside, rats can establish nests within wall cavities and under floorboards.
• Drainage Systems: Rats frequently enter properties through damaged drains or broken sewer pipes. Their ability to navigate sewage systems makes underground access points particularly concerning.
• External Doors and Windows: Even small gaps around doors and windows can serve as entry points. Weather stripping deterioration or poor installation creates opportunities for rats to slip inside.

Beyond these common points, rats demonstrate remarkable persistence in creating their own entrances. Armed with powerful teeth, they can chew through various materials including:

• Wood and plastic
• Concrete
• Brick
• Even steel

Why rats choose floorboards

The space beneath floorboards presents an ideal habitat for rats for several compelling reasons:

Perfect Environment: The dark, damp void beneath floorboards creates optimal conditions for rats. Areas where water pools beneath houses prove particularly attractive.

Protection and Privacy: As nocturnal creatures, rats seek dark spaces with minimal human contact. The area under floorboards offers both shelter and protection from predators.

Easy Access to Resources: Once established beneath floorboards, rats can:

• Access food sources through kitchen areas
• Find water from condensation or leaking pipes
• Create nesting sites in undisturbed spaces

Colonisation Potential: The protected environment allows rats to establish colonies rapidly. A single breach can lead to a significant infestation, as rats can create additional entry points by gnawing through floorboards from below.

Seasonal Factors: During colder months, the relative warmth beneath floorboards, combined with proximity to human living spaces, makes these areas particularly appealing.

Understanding these entry methods and preferences proves essential for effective control. Rats demonstrate consistent patterns in choosing entry points, often exploiting structural weaknesses or creating new access routes through their persistent gnawing behaviour. Moreover, their presence under floorboards frequently indicates broader issues with property maintenance or drainage systems that require attention.

Quick Emergency Solutions

Once you’ve identified a rat problem beneath your floorboards, swift action becomes crucial. Here are proven methods to tackle the infestation effectively.

Setting effective traps

Spring-loaded traps remain one of the most reliable solutions for catching rats under floorboards. For optimal results:

• Position traps along walls where rats frequently travel
• Screw traps firmly to a board to prevent flipping
• Bait with peanut butter, which proves irresistible to rats

To increase trap effectiveness, leave them unset but baited for 3-4 days. Subsequently, set the traps with fresh bait – this method often results in multiple catches daily. The main advantage of traps lies in retrieving dead rats promptly, preventing unpleasant odours.

Using rat repellents

Botanical repellents offer a safer alternative to harsh chemicals. These deterrents work through scent-based formulations that rats find offensive. The most effective options include:

Plant-based solutions:

• Balsam fir oil compounds
• Peppermint oil preparations
• Herbal extract combinations

Although peppermint oil requires replacement every 1-2 weeks, professional-grade botanical repellents can last 2-4 weeks between applications. For maximum effectiveness, apply repellents heavily around:

• Entry points
• Under decking
• Around waste bins
• Foundation perimeters

When to use poison

Despite its effectiveness, rat poison requires careful consideration. Professional pest controllers often use slow-acting baits that rats never associate with their declining health. Nevertheless, several crucial factors warrant attention:

Key considerations:

• Poison might cause rats to die in inaccessible areas
• Dead rats can create significant odour issues
• Risk to children and pets requires professional handling
• Special products exist to mask decomposition smells

For severe infestations, combining methods often yields better results. Professional pest control services employ trained dogs for immediate rat removal, alongside strategic placement of traps and repellents. This multi-faceted approach ensures higher success rates in eliminating rats from under floorboards.

Ultrasonic devices present another option, although their effectiveness varies considerably. These devices emit high-frequency sound waves meant to deter rats, yet require multiple units as sounds cannot penetrate walls or furniture. Therefore, they work best as part of a broader control strategy rather than a standalone solution.

Remember that successful rat control often requires persistence. Even after initial success, maintaining vigilance through regular inspections and preventive measures ensures long-term results. Professional pest control services can provide targeted solutions, particularly for extensive infestations where DIY methods prove insufficient.
