Hear a scratch behind the wall? See a single ant on the kitchen counter? Notice a tiny hole in a jumper or carpet? Small clues often point to a much bigger problem. Most household pests start out of sight — in skirting voids, lofts, fabric seams, under appliances, or behind boiler cupboards. And once they settle, they spread fast.
This guide covers the most common household pests UK homeowners encounter, how to identify them, early warning signs, and the first steps you should take. It also includes practical advice based on field experience from Bugwise Pest Control, serving homes across Romford, Dagenham, Ilford, Barking, and surrounding areas.
Catch pests early and you stay in control.

Common Household Pests UK
Below are the pests Bugwise deals with most often — with identification tips and immediate actions.
Rodents: Rats and Mice
Rodents are among the fastest-spreading and most destructive household pests. They squeeze through gaps the width of a pencil, chew through wiring, contaminate food, and breed rapidly.
How to identify:
• Scratching noises in walls or ceilings
• Droppings (dark, spindle-shaped)
• Gnaw marks on food packaging
• Greasy smear marks along skirting
• Shredded insulation or paper
What to do now:
• Seal holes bigger than a pencil
• Store food in sealed containers
• Clear refuse regularly
• If noises or droppings continue, book a survey

Ants: Black Garden Ants & Pharaoh Ants
Black garden ants enter properties in long trails, usually searching for sweet foods. Their nests sit under patios, paths and foundations. Pharaoh ants, however, are a major household risk — they split into new colonies when sprayed incorrectly.
How to identify:
• Black garden ants: black, visible trails leading from patios
• Pharaoh ants: tiny yellow-brown ants active near warm, humid rooms
What to do now:
• Wipe trails
• Fix spills
• Block entry points
• Avoid random sprays for pharaoh ants — they cause the colony to split
• Targeted gels are the professional standard
Cockroaches: German & Oriental
Two species dominate UK homes:
German cockroach
• Small, tan-coloured
• Two dark stripes behind the head
• Found in warm, humid areas (kitchens, boiler cupboards)
Oriental cockroach
• Larger, dark brown/black
• Prefers cool, damp areas (basements, bathrooms)
Cockroaches spread bacteria, contaminate surfaces, and reproduce extremely quickly.
What to do now:
• Reduce moisture and clutter
• Don’t spray randomly — it scatters them
• Arrange professional baiting and monitoring
Bed Bugs
One of the fastest-growing pest issues in the UK. Bed bugs spread through luggage, travel, shared buildings and second-hand furniture. DIY sprays rarely solve the problem — they make it worse by pushing bed bugs deeper.
How to identify:
• Small bites on exposed skin
• Black faecal specks along mattress seams
• Blood spots on sheets
• Adults (4–5 mm) hiding in cracks and fabric folds
• Activity intensifies at night
What to do now:
• Wash bedding hot
• Vacuum slowly using a crevice tool
• Avoid spraying
• Arrange professional chemical treatment programm
Fleas
Fleas are common in homes with pets — but also in empty rental properties, where larvae stay dormant until vibration wakes them.
How to identify:
• Small red bites on ankles or lower legs
• Pets scratching, licking or losing fur
• Black “flea dirt” in pet bedding
• Tiny jumping insects when disturbed
What to do now:
• Wash pet bedding hot
• Vacuum edges and under furniture daily
• Treat pets AND the home at the same time
Silverfish
Silverfish love damp, dark areas like bathrooms, boiler cupboards, basements, and kitchen units. They feed on paper, cardboard, fabrics and starch-rich materials.
How to identify:
• Silver, teardrop-shaped insects
• Fast-moving when disturbed
• Irregular holes or grazes in books, photos, or packaging
• Higher humidity in the room
What to do now:
• Improve ventilation
• Use a dehumidifier
• Fix leaks
• Seal gaps around pipe entries
Identify Household Bugs
Use these quick pointers to work out what you’re dealing with:
• Tiny yellow-brown ants indoors? Likely pharaoh ants — avoid sprays.

• Larger dark roach in cold damp areas? Oriental cockroach.
• Itchy ankle bites + pets? Fleas.
• Night-time bites + black specks on mattress seams? Bed bugs.
• Holes in wool or carpets? Carpet moth or carpet beetle larvae.
• Slow flies in loft in autumn? Cluster flies.
• Silver insects in bathrooms? Silverfish.

Frequently Asked Questions
What are the most common household pests in the UK?
The most common pests include mice, rats, ants, cockroaches, bed bugs, fleas, silverfish, and moths. Rodents and bed bugs are the fastest-growing issues across London and the South East.
How can I identify a pest in my home?
Check the room, time of activity, droppings, visible insects, bite patterns, odours, and damage to food or fabrics. If unsure, a professional inspection gives you clear answers.
Are household pests dangerous?
Some pests — especially rodents, cockroaches, and fleas — carry bacteria, trigger allergies, contaminate food, or cause property damage. Early treatment reduces health risks.
Can I get rid of pests myself?
DIY works for minor issues, such as small ant trails or a single mouse. However, bed bugs, cockroaches, pharaoh ants and established rodent activity require professional treatment.
When should I call a pest control technician?
Call professionals if droppings appear regularly, insects spread to multiple rooms, DIY treatments fail, or you suspect bed bugs or cockroaches.
