7 Warning Signs of a Cockroach Infestation
Cockroaches are nocturnal and avoid light — if you see one during the day, the infestation is likely already severe. Look for these signs in your London home or business.
Live Cockroaches
Seeing cockroaches during the day — especially in kitchens, under appliances or around drains — is a strong sign of a serious infestation. They are normally only active at night.
Cockroach Droppings
Small, dark, cylindrical droppings resembling black pepper or coffee grounds on kitchen surfaces, behind appliances, inside cupboards and along skirting boards.
Egg Cases (Oothecae)
Brown, oval-shaped egg cases (6–9mm) found behind fridges, under sinks, inside cupboard hinges or along wall junctions. Each case can contain 15–40 eggs.
Shed Skins
Cockroaches shed their exoskeleton as they grow. Pale, papery shell casings found in dark, hidden areas like under appliances or inside electrical units indicate an active infestation.
Smear Marks
Dark, irregular smear marks along walls, floor edges and horizontal surfaces — left by cockroaches as they travel their regular routes in moist environments.
Musty Oily Odour
A strong, oily, musty smell — particularly around kitchen appliances, under sinks or in boiler cupboards — is a clear sign of cockroach activity and should not be ignored.
Damaged Food Packaging
Gnaw marks on food packaging, cardboard boxes or organic material in kitchen cupboards, pantries or storage areas indicate cockroach feeding activity.

Our proven 5-step cockroach control process is designed to eliminate infestations completely — including eggs — and prevent them returning.
Survey & ID
Full property survey to identify cockroach species, harbourage areas, entry points and the severity of infestation before any treatment begins.
Gel Baiting
Professional-grade insecticide gel bait applied in precise locations near harbourage sites. Cockroaches consume and transfer bait back to the nest — eliminating the colony.
Residual Spray
Residual insecticide applied to walls, floor junctions, behind appliances and inside voids — creating a lasting barrier that kills cockroaches on contact.
IGR Application
Insect Growth Regulator (IGR) applied to break the cockroach lifecycle — preventing eggs and nymphs from developing into reproducing adults.
Follow-Up & Sign-Off
Return visit to assess bait consumption, check activity levels and confirm the infestation is fully eliminated. Fully guaranteed with free revisit.

Why Cockroaches Are a Serious Problem in London
London's warm buildings, busy hospitality sector and complex drainage network make it one of the UK's highest-risk cities for cockroach infestations. The German cockroach (Blattella germanica) is particularly prevalent in London — thriving in the warm, humid conditions found in restaurant kitchens, takeaways and residential blocks. A single German cockroach female can produce up to 300 offspring in her lifetime, meaning infestations escalate rapidly without professional intervention.
Cockroaches carry and spread Salmonella, E. coli, Listeria and Staphylococcus bacteria, contaminating food surfaces and preparation equipment. In commercial kitchens, a cockroach infestation can result in a failed food hygiene inspection, significant fines and forced closure.
Our Cockroach Treatment Approach in London
Unlike domestic spray products which only kill cockroaches on contact, our professional gel bait treatment exploits cockroach social behaviour — cockroaches consume the bait and transfer it to nest-mates and eggs, creating a cascade effect that eliminates the entire colony. We combine this with residual insecticide spray and Insect Growth Regulators (IGR) to break the breeding cycle and prevent re-infestation.
All products we use in food environments are specifically approved for use in commercial kitchens and comply with UK food safety legislation, including HACCP requirements. Treatment is discreet and causes minimal disruption to your business operations.
