Signs of a Cockroach Infestation

• Dark droppings resembling coffee grounds or ground pepper, often along skirting or behind appliances
• A persistent musty or oily smell, especially in the kitchen or utility area
• Shed skins or small dark egg cases tucked into corners and crevices
• Cockroaches seen during the day, indicating a large hidden population

Cockroaches breed extremely quickly. If you have any suspicions, don’t delay in seeking a professional set of eyes.

Types of Cockroach

German cockroaches are small, fast-breeding, and drawn to warmth, so they cluster around ovens, fridges and dishwashers.

Oriental cockroaches are larger and slower, and prefer cool, damp spots like drains, basements and under flooring.

The species, and their habits, change how we approach treatment.

Why DIY Treatment Rarely Helps

Shop sprays kill what's moving, but they miss their hideaways. Egg cases are glued deep into cracks and voids, well away from any surface spray, so a new generation hatches within weeks regardless. Many UK cockroach populations have also built up resistance to the pyrethroids found in consumer products, so even direct isn’t enough to kill them.
