Identifying and solving the underlying root causes is essential to eradication of pest recurrence. Chemical and treatment only approaches, by themselves, are not effective. Our IPM Program addresses the underlying root causes that cause pest infestations.

We service Commercial Office Buildings, Hotels, Hospitals, Retail Stores, Warehouses, Manufacturing Plants, etc. and understand the challenges faced to control pest problems.

The following are some common challenges commercial environments face along with quick, helpful tips to address them:

HOLES, OPENINGS, ENTRY POINTS, GAPS. This is caused by utility pipes, electrical conduits, water and gas lines, communication cables, heating, air conditioning, plumbing, fire sprinklers and along building exteriors where the wall framing or siding meets the foundation.


  • Entry points should be regularly monitored for             excess openings caused by equipment repair, installation or modification.
  • Seal all holes and openings larger than 1/2 inch (1.3 cm) across with heavy materials that will resist rodent gnawing like steel wool, copper gauze or screen wire packed tightly into openings.
  • Always trap rodents before sealing interior walls to avoid odors, stains,and an influx of insects that feed on decaying rodent carcasses.


  • Use only metal window screening materials where windows or doors are accessible to rodents. Avoid unnecessary ledges outside windows.
  • All vents and duct openings for heating and air conditioning should be screened.
  • In some cases, power vents can be covered with hinged metal plates


  • Openings to drains should have adequate screens or metal grates held firmly in place to prevent rodent entry. Grate openings should not exceed ¼ inch.
  • Gutter and other drain covers must be kept clean of debris to prevent water backup.


  • Openings can be prevented by well-formed and finished concrete work and installation of tight wall framing and siding, or installing metal screed-type flashing between the siding and the foundation.
  • Repair cracks in foundations and floors with concrete or masonry grout.

FOOD STORAGE & DISPOSAL. Food disposal, refuse, and damaged goods areas are often located close to food handling or storage areas and are not sealed from pests. Outside doors in kitchens are often left ajar or fit poorly.


  • Food preparation equipment (mixers, stoves, counters, or refrigerators) should be raised off floors or counters to provide access for easy cleaning.
  • A smooth stainless steel floor allows for easy cleaning of food spills and to prevent harborage.
  • Warehouse stock should be stacked off the floor on pallets 18 to 24 inches away from walls and should be rotated often to prevent development of infestations and for proper cleaning and inspection.


  • Doors should fit tightly, the distance between the bottom of the door and the threshold not exceeding 1/4 inch.
  • Install flashing or a metal channel on the lower edge of doors, particularly softwood doors.
  • Mechanical door-closing devices save time and help overcome human negligence.
