5 Warning Signs You Have a Pest Problem (And Don’t Know It Yet)
Most homeowners in Newmarket don’t realise they have a pest problem until they actually see a mouse scurrying across the floor or a wasp nest the size of a football in the loft. However, pests are experts at staying hidden. By the time you see one out in the open, the infestation is usually well-established.
Identifying a problem early can save you hundreds of pounds in structural repairs and protect your family from the health risks associated with vermin. At Newmarket Pest Solutions, we recommend looking out for these five subtle “red flags” that indicate you have unwanted visitors.
1. Unusual Noises in Walls or Lofts
If you hear scratching, scurrying, or thumping sounds—especially at night—it is rarely “the house settling.” In Newmarket’s older townhouses and rural properties, these noises are often the first sign of a rodent infestation.
Rats and Mice: Usually heard at night. You might hear them moving behind skirting boards or across ceiling joists.
Squirrels: More likely to be heard in the early morning or evening. They tend to be louder and heavier than mice.
Birds: If the scratching is accompanied by chirping or wing-fluttering during the day, you likely have birds nesting in your eaves.
2. Droppings and Smear Marks
Droppings are the most obvious physical evidence of pests. Identifying the shape and size of the droppings can help you determine exactly what you are dealing with.
Mice: Small, pointed droppings about the size of a grain of rice.
Rats: Larger, spindle-shaped droppings, usually found in clusters.
Smear Marks: Rodents have oily fur. As they repeatedly use the same paths along walls or through gaps, they leave dark, greasy “smear marks” on the skirting boards or brickwork. If you see dark staining around a small hole, it is a high-traffic entry point.
3. Evidence of Gnawing and Damage
As we have discussed in our guides, rodents have teeth that never stop growing. They must chew to keep them down.
Check your kitchen cupboards for “chewed” corners on food packaging. More importantly, look at your property’s exterior and loft. If you see jagged holes in plastic soffits or wooden beams—or if you notice unexplained electrical faults—you may have a squirrel or rat problem that is putting your home at risk of fire.
4. Unexplained Odours
A sudden, persistent, and unpleasant smell can be a major indicator of an infestation.
Ammonia-like smell: A strong, stale smell of ammonia often indicates a large mouse infestation, as they use urine to mark their territory.
Musty/Damp smells: This can indicate cockroaches or bed bugs, though these are less common in the Newmarket countryside than in city centres.
Rotting smell: A heavy, sweet, and sickly odour usually indicates that a pest has died inside a wall cavity or under floorboards. This requires professional removal to prevent secondary infestations of flies.
5. Visual Sightings and “Nesting” Materials
Keep an eye out for “scraps” that shouldn’t be there. If you find shredded paper, insulation, or fabric tucked into a corner of the loft or behind an appliance, you are looking at a nest.
Furthermore, pay attention to the outside of your home. If you see a constant “flight path” of insects entering a specific hole in the brickwork or under a roof tile, you have likely identified a wasp nest in its early stages.
What To Do Next
If you have spotted any of these signs, don’t wait for the problem to get worse. Pests do not leave on their own; they only breed and cause further damage.
