The 10 Most Common Pest Problems Found in Berkshire Homes

Every county has its own pattern of pest activity, shaped by housing types, climate and geography. In Berkshire, homeowners tend to report the same handful of problems again and again. Knowing what to look out for makes it much easier to catch an issue early, before it turns into something more disruptive.

1. Mice

Mice are probably the most commonly reported pest across Berkshire homes. They're small enough to squeeze through gaps the width of a pencil and are often first noticed through droppings, gnawed packaging or scratching sounds in the walls at night.

2. Rats

Rats are drawn to gardens, sheds and drains, and will happily move indoors if there's food and shelter on offer. Burrows near decking or compost heaps, and greasy smear marks along regular routes, are common giveaways.

3. Wasps

Wasp nests are a familiar sight in lofts, wall cavities and garden sheds during the summer months. A nest that starts small in spring can house thousands of wasps by August, so it's worth acting on regular sightings around one spot early.

4. Bed bugs

Bed bugs are increasingly common and have nothing to do with cleanliness — they travel via luggage, secondhand furniture and public transport. Small blood spots on bedding and itchy bites in a line are typical early signs.

5. Fleas

Fleas usually arrive with a pet but can quickly spread into carpets, sofas and bedding. Bites around the ankles, especially after sitting on the floor, are a common first indication.

6. Carpet moths

Carpet moths quietly damage wool carpets, rugs and stored clothing. Small bald patches in carpets, particularly in low-traffic areas like under furniture, are a classic sign of an infestation that's already been going on for a while.

7. Ants

Ants become a nuisance in kitchens and gardens once the weather warms up, forming visible trails to any accessible food source. They're rarely a serious problem but can be persistent once a colony has found a reliable food supply.

8. Cluster flies

Cluster flies gather in roof spaces and window recesses over autumn and winter, looking for somewhere sheltered to overwinter. Homeowners often notice sudden clusters of sluggish flies on sunny windowsills.

9. Silverfish

Silverfish favour damp, dark spots such as bathrooms, kitchens and basements, feeding on paper, glue and fabric fibres. Their presence is often a sign of excess moisture worth addressing.

10. Squirrels in loft spaces

Grey squirrels can cause real damage once they get into a loft, gnawing on timber and cabling and building nests in insulation. Scratching noises in the roof during the day, rather than at night, often point to squirrels rather than rodents.

Why these pests keep coming back

Many of these problems share common root causes: gaps around doors and pipework, easy access to food, and cluttered storage areas that go unchecked for months at a time. Addressing those underlying conditions, alongside treating any active infestation, is what stops a pest problem returning a few months later.

Dealing with any of these

Spotting a problem early is the best way to keep it manageable, but some pests — particularly wasp nests, rats and established bed bug or carpet moth infestations — are genuinely difficult to deal with safely on your own. Pest Services Berkshire provides removal services for bed bugs, carpet moths, fleas, mice, rats and wasp nests across Slough, Reading and the wider county, with wasp nest treatment available at a fixed £90. If any of the above sounds familiar, it's worth getting in touch for advice on the best way forward.
