Common Pest Problems in East London Homes
Rats, mice, bed bugs, wasps and other pests are a common concern for homes across East London. Knowing the early warning signs can help you deal with a problem before it becomes more established.
East London has a varied mix of older housing, modern flats, busy high streets, restaurants, gardens and densely populated residential neighbourhoods. That variety can also provide pests with plenty of opportunities to find food, shelter and access to buildings.
Rats and mice may enter through damaged drains or small gaps around a property. Bed bugs can arrive on luggage, furniture or clothing. Ant colonies may become established close to kitchens and patios, while wasps often use roofs, lofts, walls and sheds for nesting.
For homeowners, tenants and landlords, recognising these problems early can make treatment much easier.

Rats
Rats are one of the most common urban pest problems and can become established anywhere they have access to food, water and shelter.
They may enter homes through damaged drains, gaps around external walls, broken vents, roof spaces or openings around pipework. Once inside, they can move through kitchens, lofts, storage areas and wall cavities.
Common Signs of Rats
- Large rodent droppings
- Scratching or movement at night
- Gnaw marks on wood, plastic or cables
- Damaged food packaging
- Greasy marks along regular travel routes
- Unusual smells in concealed areas
Rat activity may also be noticed around gardens, bins, sheds or drains before rodents are seen inside the property.
For recurring activity, professional rat and mouse control can help identify where rodents are entering as well as where they are active inside the building.
Mice
Mice are smaller than rats and can gain access through very narrow openings around buildings.
The British Pest Control Association notes that mice can squeeze through gaps of around 5mm. Once inside, they may settle behind kitchen units, beneath floors, inside cupboards, lofts or wall cavities.
Common Signs of Mice
- Small dark droppings
- Scratching noises, particularly at night
- Chewed food packaging
- Gnaw marks
- Shredded nesting material
- Strong ammonia-like smell
BPCA notes that a single mouse may leave approximately 80 droppings in a day, which means even a relatively small infestation can leave noticeable evidence.
Mice can also move between neighbouring properties where suitable access routes exist.

Bed Bugs
Bed bugs are not caused by poor hygiene. They can be carried into clean homes on luggage, clothing, furniture and other belongings.
Once introduced, they usually remain close to places where people sleep or rest.
Where Bed Bugs Commonly Hide
- Mattress seams
- Bed frames and headboards
- Sofas and upholstered furniture
- Furniture joints
- Skirting boards
- Cracks close to sleeping areas
Signs can include bites, small blood spots on bedding, dark spotting around mattresses, shed skins and live insects.
If activity continues or spreads into more than one room, professional bed bug treatment may be required.
Wasps
Wasps become particularly noticeable during warmer weather, but the nest itself may remain hidden.
Common nesting locations include lofts, roof spaces, wall cavities, sheds, garages and trees.
Signs of a Wasp Nest
- Wasps repeatedly entering the same opening
- Heavy activity around one part of a roof
- Buzzing from ceilings or wall cavities
- A visible nest in a loft, shed or tree
Wasps may become defensive when a nest is disturbed. Attempting to block the entrance before treatment can also cause them to search for another route.
See our wasp and bee control service .
Ants
Ants live in colonies, and the insects visible inside a home are usually workers travelling between the nest and a source of food or water.
Nests may be located beneath paving, in soil, around building foundations or inside sheltered areas of a property.
Signs of an Ant Infestation
- Persistent ant trails
- Activity around cupboards and food
- Ants repeatedly appearing near cracks
- Small piles of disturbed soil
- Activity returning soon after cleaning
Cleaning away visible ants may remove the trail temporarily without affecting the colony.

Cockroaches
Cockroaches favour warm, sheltered areas where food and moisture are easily available.
Kitchens, cupboards, bathrooms, drains and areas behind appliances can all provide suitable conditions.
Common Signs of Cockroaches
- Live or dead cockroaches
- Small dark droppings
- Egg cases
- Persistent musty odour
- Activity around kitchens or appliances
Cockroaches are particularly important to address in food-related environments because they can move between waste, drains and food preparation areas.
See our cockroach control service .
Fleas
Fleas are often associated with pets, but an infestation can remain in carpets, furniture and soft furnishings even when the original animal host is no longer present.
People often first notice bites around their ankles or lower legs. Pets may also scratch more frequently.
If fleas are appearing in several rooms, treating only the pet may not be enough because other stages of the flea lifecycle may be present throughout the property.

Squirrels in Loft and Roof Spaces
Grey squirrels can become a problem when they gain access to lofts and roof spaces through damaged roofing, fascia gaps or other openings.
Once inside, squirrels may disturb insulation and gnaw building materials.
Signs of Squirrel Activity
- Daytime scratching or movement in the loft
- Damaged insulation
- Nesting material
- Squirrels repeatedly approaching the roof
Because rodents and squirrels can create similar noises, correct identification is important before treatment.
See our squirrel control service .
Why East London Properties Can Experience Pest Problems
Pest activity is usually connected to a combination of food, water, shelter and access.
East London includes densely populated neighbourhoods, commercial centres and a wide range of property types. Closely built homes and flats can also mean that some pests are able to move between neighbouring properties when suitable routes are available.
Common contributing factors include damaged building fabric, gaps around pipes, accessible waste, drains, roof defects, uncovered food and vegetation close to external walls.

When Is It Time to Call a Pest Controller?
Not every occasional pest sighting requires professional treatment. Repeated activity or evidence of an established infestation is more significant.
- Droppings continue appearing after cleaning
- Scratching is regularly heard at night
- Several rooms show pest activity
- DIY treatment has not solved the problem
- A wasp nest is difficult to access
- Bed bugs have spread beyond one room
- Rodents repeatedly return
- A pest problem is affecting a business or rental property
Not Sure What Pest You Have?
Tell Parker Pest Control what you have seen, heard or found around the property and we can advise on the next step.
Request a QuoteWhy Professional Pest Control Is More Than Just Treatment
Professional pest control is not simply about dealing with the pest currently visible.
A useful assessment should also consider why the pest is present and what may be allowing the problem to continue.
For rodents, that may mean identifying gaps, drains or food sources. For ants, it can mean locating the colony rather than only treating individual workers. For bed bugs, treatment may need to extend beyond the mattress to other hiding areas.
Combining identification, treatment and practical prevention can provide a more complete response to recurring pest problems.
Simple Ways to Reduce Pest Problems at Home
No property can be made completely pest-proof, but basic maintenance can reduce opportunities for pests to settle.
- Store food in sealed containers
- Clean crumbs and spills promptly
- Avoid leaving pet food out overnight
- Keep bins securely closed
- Check doors, vents and pipework for obvious gaps
- Keep vegetation maintained around buildings
- Inspect roofs, sheds and outbuildings for damage
- Deal with persistent leaks or moisture
Frequently Asked Questions
What are the most common pests in East London homes?
Rats, mice, wasps, bed bugs, ants, cockroaches and fleas are all common urban pest problems. UK pest activity data for 2025 showed rats and mice as the two most frequently recorded pest groups in the BPCA dataset.
How do I know if I have rats or mice?
Common signs include droppings, scratching noises, gnaw marks, damaged food packaging, nesting material and unusual smells. The size and location of the evidence can sometimes help identify which rodent is present.
Why do mice keep getting into homes?
Mice look for food, shelter and warmth and can use very small openings to enter buildings. BPCA notes that mice can squeeze through gaps of around 5mm.
Are bed bugs caused by poor hygiene?
No. Bed bugs can be introduced into clean properties through luggage, clothing, furniture and other belongings. Cleaning alone will not necessarily remove an established infestation.
Should I remove a wasp nest myself?
An established nest can become dangerous when disturbed. If the nest is large, difficult to access or close to people, professional assessment is usually the safer option.
Why do ants keep returning after cleaning?
The ants you see are usually worker ants travelling from a colony. If the nest remains active and food or water is available, ants may continue using the same route.
Can pests spread between neighbouring properties?
Yes. Some pests can move between neighbouring properties where access routes exist, particularly in terraces, flats and closely connected buildings.
When should I call a professional pest controller?
Consider professional help when pest activity keeps returning, several areas are affected, the source cannot be identified, DIY treatment has failed or the infestation is affecting people, food, property or a business.
