We no longer provide a pest control service, if you have a problem with cockroaches in your home, please consider contacting a pest control specialist. 

Cockroaches like:

  • Concealment
  • Comfortable temperature
  • Food and moisture
  • Society

Cockroaches like to avoid daylight and hide in cracks and crevices, known as harbourages. They eat almost anything, including cardboard, and come out to forage at dusk and early night. They thrive at temperatures of 20-35 degrees Celsius, more towards the higher end of the range. They need access to water. They stay together in groups. They are mostly found in kitchens and toilets, such as, behind cookers or in laundry baskets, at the backs of drawers, behind peeling wallpaper, etc. They move along water pipes and air ducts. Tower blocks are particularly vulnerable to infestation because of the ease with which cockroaches can move through the building. The design of buildings and the materials used in their construction can facilitate the spread of cockroaches.

Cockroaches can walk, run, jump and sometimes fly. But probably their main movement from building to building is in transported goods; this can even occur in ships and aircraft.

Cockroaches and disease

Cockroaches are implicated in the transfer of disease. They are bearers of pathogens such as salmonella and staphylococcus. They have been associated with outbreaks of gastroenteritis, typhus and skin diseases.

Contact with cockroaches can lead to a number of allergic illnesses, including dermatitis, urticaria (another skin disease), rhinitis, bronchitis and asthma. Laboratory workers involved in the breeding of cockroaches for research are particularly prone to these conditions.

Some people have an aversion to cockroaches amounting to phobia and can suffer anxiety when in the presence of the insects.

Keeping cockroaches out

Good hygiene is essential in preventing or limiting infestation. It is vital to deny cockroaches food, water and shelter. Dishes should be washed promptly, food stored in tightly sealed containers, working surfaces kept clean, and all scraps and crumbs cleared up. Rubbish should be kept in containers with tight lids and the bags properly sealed when moved outside. Water spills should be mopped up and all water leaks, sweating pipes, etc. repaired. Remove any clutter where cockroaches might live and mend any holes and cracks in walls. Seal openings around pipes, remove paint and loose wallpaper and replace broken tiles.

If you have tried all of the above advice to eliminate cockroaches from your home and still have an infestation consider contacting a pest control specialist.
