OF Cockroaches


Cockroaches can leave excretion marks that look like small black specks.

They can also leave droppings that resemble loose coffee grounds.

Egg cases

Oriental cockroaches deposit egg cases that are a dark reddish-brown colour.

These are usually left in a sheltered area close to a food source.

Shed Skins

Cockroaches can shed their skin 5-8 times as they mature into adults.

Their shed skins can often be found where the cockroaches are sheltering.

where to check for Cockroaches

  • Kitchens - Check inside/under kitchen units. Cockroaches can often be found in upper inside corners of kitchen cabinets. Check the crevices of any appliances that may provide warmth and shelter, e.g. cookers and fridges.

  • Bathrooms - Cockroaches can often be found in bathroom cabinets and areas with pipework, e.g. under sinks. Check any dark space they can take shelter with access to water.

  • Basements - Cockroaches can often be found in cracks in wooden beams or floor cavities.

smear marks

In areas with an abundance of water, cockroaches will leave brown, irregular smear marks.


These are most commonly found at wall-floor junctions where cockroaches travel. 

Smell of Cockroaches

Cockroaches can produce a pungent, musty smell that worsens as the infestation goes on.

The smell can linger in the air and taints any items or food the cockroaches come into contact with.

Getting a professional pest control team to manage your cockroach problems is essential if you want to avoid these risks. 


Diseases caused by Cockroaches

  • Fungus - shed skins and droppings from cockroaches can develop fungi that can affect the eyes and lungs.

  • Bacteria - cockroaches can carry bacteria that cause serious illness, e.g. E.coli and cholera.


food contamination

Cockroaches can cause food poisoning by tracking germs across your kitchen surfaces.

Salmonella can be retained in the digestive systems of cockroaches for over a month, and can be transmitted to your food through their droppings.
