Cockroach Treatment Preparation For (Commercial) Use

Sanitation is essential in cockroach control. Proper control does not come without it. The following steps must be taken for optimal results. This list is not all-inclusive. The general premise is that if something can be cleaned, clean it!

Items To Be Completed Prior To Our Arrival:

  • Cover or remove open food, napkins, cups, silverware, plates, utensils, pans, etc. from the treatment area.
  • Remove boxes stored directly on the floor.
  • Remove or discard outdated merchandise.


  • Do not cover open storage shelves as these will all require inspection and/or treatment.
  • Shut off exhaust hoods and fans.
  • Clean all dining areas, food prep surfaces, sink drains, floor drains, trash containers, recycling bins, sump pumps, refrigeration drip pans, and garbage disposals.
  • Clean kitchen thoroughly, including floors, stoves, range hoods, and food prep surfaces.
  • Clean dishwasher(s).
  • Clean behind and underneath kitchen equipment and shelving.
  • Bathroom cabinets and under sinks should be cleaned. Wash cabinets inside and out, wipe out drawers, clean sinks, inside and outside of toilets and scrub bathroom floors.
  • Repair leaky beverage dispensers, damaged flooring, plumbing or sewage leaks (if applicable). Seal or caulk holes in walls/around utility lines, cracks, and crevices (if applicable).
  • Vacuum all carpets (if applicable).

After Our Treatment Is Complete:

  • No person can re-enter the premises for at least 4 hours unless specified otherwise. Run exhaust systems.
  • Destroy any open food or napkins missed.
  • Wash any missed cups, silverware, plates, pans, etc. before re-use. Thoroughly wash grills, cutting boards, and food prep surfaces before re-use. Wash all exposed eating surfaces (including tables and bars).
  • Do not wash any treated surfaces such as baseboards.
  • Store items in the cooler if there's room.
  • Clean dining room tables and store items on them (after cleaning), covering with linens or garbage bags.
  • Store items in boxes or plastic tubs, covering with plastic wrap.
  • Cover ice chests, fryers, and open tubs.
  • It's normal to see roaches for several days post-treatment. It may take days for roaches in inaccessible areas to contact treated surfaces.
  • Further treatments might be required. A 30-day warranty comes with the treatment (only if sanitation recommendations were followed).
