We’ve all seen them before. They scamper across the floor and the walls, causing panic as they appear around corners or amongst stored food items. But don’t be fooled by the fact that cockroaches are so common—they’re still some of the filthiest pests imaginable.

In addition to evoking feelings of surprise and disgust, cockroaches are also a major health concern. They can spread disease, contaminate food, trigger allergies and even cause asthma symptoms. In fact, cockroaches are known for their ability to transmit harmful pathogens like E. coli, Salmonella spp. and typhus, plus viral diseases such as poliomyelitis.

But of course, cockroaches aren’t concerned with your health. They’re eager to invade your space, slipping through cracks and spaces as small as 1/6 of a centimetre wide. And once they’re in, they can begin reproducing rapidly. Before you’re even aware of these unwanted visitors, they may have started multi-generational family in your facility.

To know how to prevent cockroaches, it’s crucial to know where to look for them. Here are a few places to start:

  • Hidden, protected places like wall voids, false ceilings, beneath floors and in or under appliances and equipment
  • Food preparation and dining areas
  • Employee locker rooms
  • Storage areas and closets
  • Laundry areas
  • Waiting areas

Once you’ve identified potential problem areas, it’s time to take steps to proactively prevent these crawling critters from encroaching on your operations. Some basic tips for prevention include:

  • Sweeping and mopping regularly to remove debris
  • Cleaning spills and fixing leaking appliances
  • Removing moisture sources
  • Inspecting incoming shipment boxes for droppings as well as live or dead cockroaches
  • Sealing cracks, gaps and holes in doors, windows and walls
