It is an important distinction because the two problems require different approaches.
Mouse droppings are small, dark and pointed at both ends, roughly the size of a grain of rice. You will typically find them along walls, under kitchen units and in cupboards. Rat droppings are larger and blunter. If you are not sure what you are looking at, do not guess. Getting the identification wrong means treating for the wrong pest.
Gnaw marks are another indicator. Mice chew constantly because their incisor teeth never stop growing. They will work through electrical cables, water pipes, food packaging, insulation and even soft concrete. The gnaw marks tend to be small and ragged. On cables in particular, this is a genuine fire risk that should not be left unaddressed.
You are also more likely to hear mice than to see them. Scratching and scurrying in walls, under floors and in loft spaces is one of the most common first signs. It tends to be most noticeable at night when the house is quiet and the mice are active.
Mice are opportunists. They need very little to establish themselves: a small entry point, a food source nearby and somewhere to nest undisturbed.
Swindon has a significant stock of older terraced housing, particularly in areas like Gorse Hill, Pinehurst and Rodbourne. These streets were built at a time when no one was designing with mouse-proofing in mind. Over decades, small gaps open up around pipework, airbricks crack, pointing erodes and gaps appear where different materials meet. A mouse can squeeze through a hole no bigger than the diameter of a pencil. In terraced streets, where houses share cavity walls, an infestation in one property spreads to neighbouring homes without anyone opening a door.
The growth of Swindon has also pushed mice out of surrounding fields and hedgerows into residential areas. New developments along the town's edges disturb established territories, and mice simply move into the nearest available warm structure. Town centre flats, takeaways, commercial units and residential properties above food businesses are particularly susceptible.
This is not a criticism of anyone who has tried. It is a practical reality.
Snap traps and basic bait blocks can catch individual mice, but they do not address the root cause. If the entry point remains open, more mice will come. If there is a nest, catching one or two will barely make a dent in the population. Some mice become cautious around traps or avoid bait that has been placed incorrectly.
Over-the-counter poisons also carry a risk if you have children, pets or wildlife nearby. The incorrect use of rodenticides is increasingly regulated precisely because of the harm they can cause to non-target animals.
The other issue is that DIY treatments give people the impression the problem is under control when it is not. A few weeks later the problem resurfaces, often having spread further in the meantime.
When we attend a mice infestation, we do not just put bait down and leave. The job starts with a thorough survey of the property.
We look at where the activity is concentrated, identify likely nesting sites and locate the entry points the mice are using to get in and out. Entry points are often in places people do not check: the gap where a gas pipe comes through a wall, the space under a bay window floor, a damaged airbrick at ground level, or where a downpipe passes close to the fascia in the loft space.
Once we have a clear picture, we put a baiting programme in place using professional-grade rodenticides in tamper-resistant bait stations. These are placed in areas of confirmed activity and positioned safely away from children and pets. We advise on hygiene measures that reduce the attractiveness of the property to mice, because a well-fed mouse is harder to bait.
Proofing is the part of the job that delivers lasting results. We seal the entry points we have identified using materials that mice cannot gnaw through, including wire mesh, hardened fillers and door brush strips where appropriate. Proofing without treatment, or treatment without proofing, both leave the job half done.
We schedule a follow-up visit to check bait uptake, replace stations as needed and confirm the infestation has cleared.
We cover the whole of Swindon and the surrounding area, including Gorse Hill, Pinehurst, Rodbourne, Park North, Park South, Walcot, Eldene, Covingham, Liden, Nythe, Toothill, Shaw, Stratton St Margaret, Wroughton and the town centre. We also cover surrounding villages and rural properties across North Wiltshire and the Vale of White Horse.
We use professional-grade rodenticides in tamper-resistant bait stations that are specifically designed to prevent access by children, pets and non-target wildlife. We will advise you on placement and any precautions specific to your property before we begin.
Not usually. The products we use do not require you to vacate. We will let you know if anything specific applies to your situation when we attend.
If the proofing work is carried out properly, the mice cannot re-enter. The most common reason an infestation returns is that entry points were not fully sealed. Proofing is part of every job we do, not an optional add-on.
