Rat The space beneath ground-floor floorboards, particularly in older Stowmarket properties with suspended timber floors, can be an attractive spot for rats. It is dark, sheltered from the weather, and often connects to other voids and gaps around the property, giving rats easy movement without being seen.
Understanding what draws rats under a floor can help explain why the problem has started, and what needs to change to stop it happening again.
Why rats choose the space under floors
Suspended floors are usually accessed via air bricks, which exist to ventilate the space and prevent damp. If an air brick is damaged, missing its mesh, or simply too large a gap, it becomes an open door for rats. Once inside, the void under the floor is quiet, close to warmth from the rooms above, and often close to drains or outside food sources too.
- Damaged or missing mesh on air bricks
- Gaps around pipework passing under the floor
- Nearby food sources, such as bins, compost or bird feed
- Cracked or damaged drains running near or under the property
- Cluttered gardens or outbuildings providing cover close to the house
- Nearby overgrown vegetation offering a sheltered route to the property
Signs rats are under your floor
Scratching or movement sounds coming from below rather than above, a musty or ammonia-like smell rising through the floor, and droppings found near air bricks or in cupboards built over the void are all common signs. Pets, particularly cats and dogs, often notice activity under floors before their owners do.
What treatment involves
Because the space under a floor is hard to access directly, treatment typically involves baiting and monitoring via air bricks and other access points, alongside identifying and repairing the damage that let rats in. Follow-up visits confirm the treatment has worked before entry points are permanently sealed.
When to seek an inspection
It is easy to put off dealing with noises under a floor, particularly if they are faint or infrequent at first. But because this space is so well hidden, an infestation here often has more time to grow before it is noticed compared to one in a loft or garden. If you have heard repeated movement under your floor over more than a few nights, or noticed a smell you cannot otherwise explain, it is worth arranging an inspection rather than waiting to see if it settles down on its own.
