5 Warning Signs of a Pest Problem in Newcastle City Centre Properties

City centre living and working comes with its own pest risk profile: older buildings, shared walls, nearby food outlets, and a lot of coming and going through communal entrances. Excel Pest Control and Environmental Management, with a base on Clavering Place covering Newcastle upon Tyne, sees the same handful of warning signs come up again and again in city centre flats, offices, and commercial units. Here are five worth acting on before they become a bigger problem.

5. Unexplained noises in walls, ceilings, or under floors

Scratching or scurrying sounds at night, particularly in older city centre buildings, is one of the earliest and most commonly ignored signs of rodent activity. It's easy to assume it's pipework or a neighbouring property, especially in shared or converted buildings common around Newcastle city centre. If the noise is consistent rather than a one-off, it's worth treating it as an early warning rather than background noise to live with.

4. Droppings near food storage or skirting boards

Small dark droppings near cupboards, under sinks, or along skirting boards are a clear sign that something has already been active in the space, not just passing through. In commercial kitchens and food premises this is also a food hygiene issue with legal implications, not just an inconvenience. Spotting droppings means the problem has already progressed past the earliest stage, so it's worth treating as more urgent than noises alone.

3. Gnaw marks on packaging, wiring, or woodwork

Rodents need to gnaw constantly to keep their teeth at a manageable length, and they're not fussy about what they use to do it. Chewed food packaging, damaged skirting boards, or worse, gnawed electrical wiring, are all signs of established activity rather than a single pest passing through. Gnawed wiring in particular is a genuine fire risk, which makes this one of the warning signs worth acting on immediately rather than monitoring.

2. A sudden increase in flies, ants, or other insects indoors

A noticeable jump in flies, ants, or other insects inside a property, especially somewhere that wasn't previously a problem, usually points to a nearby food source, standing water, or a nest close by. In city centre buildings with shared bin areas or older drainage, this can be a symptom of a wider building issue rather than something isolated to one flat or unit. It's worth flagging to a managing agent or landlord as well as arranging treatment, since the source may be communal.

1. A strong, persistent smell with no obvious source

An unexplained smell that doesn't go away with normal cleaning, particularly something sweet, musty, or unpleasant coming from behind walls or under floors, is often one of the last signs before a problem becomes serious. It can indicate anything from an established rodent nest to a dead pest inside a void space that's hard to reach without proper equipment. This is generally the point where a professional inspection stops being optional and becomes necessary.

What to do next

None of these signs on their own is necessarily a crisis, but together, or left unaddressed, they tend to escalate rather than resolve. Getting a proper inspection at the first sign, rather than waiting for several to stack up, is almost always the simpler and less disruptive route. If any of this sounds familiar in a Newcastle city centre flat, office, or commercial unit, it's worth getting it looked at sooner rather than later.
