Having exceptional hygiene standards with a structured cleaning schedule and pest management contract in place, is key to monitoring and preventing an outbreak of cockroaches.

Cockroach Control Flats

Oriental and German cockroaches can thrive in large buildings and are well known to infest blocks of flats in London. With many residents comes the risk of cockroach infestation due to poor hygiene and cockroaches being brought in through contaminated supplies. There is also risk of external influences with large blocks of flats typically in built up areas of central London. Mercury Pest Control provides systematic routine inspections for blocks of flats with in-depth monitoring of key areas such as refuse rooms, riser cupboards and plant rooms. Having this in place will help detect and then control an infestation before it spreads throughout a building causing distress and further costs to all those involved.

  • Exceptional hygiene – making sure kitchen areas are regularly deep cleaned and spillages are cleaned up. 
  • Bin areas are kept in good order with regular jetting and disinfecting if feasible. 
  • Routine inspections for commercial sites where monitoring traps can be applied to detect activity. 
  • Pest awareness training for staff – especially in hospitality and food production sites.
  • Good storage of foodstuffs and visual checks of the kitchen area pulling out appliances between routine pest inspections. 
  • Ensure your suppliers are compliant with food hygiene legislation. 
  • Repair leaks and damaged drainage pipes. 
  • Avoid second hand kitchen appliances if the source and status of the previous site is unknown. 
  • Regular jetting of the drainage system – this will help clear organic matter build up in the pipework which can attract Oriental Cockroaches.

  • Avoid staying at infested properties where activity is present.
