  • discard all suspected food in an outdoor garbage bin.
  • Clean all cabinets, cupboards and shelves where an infestation occurred. Clean with soap, water and vacuum.
  • Storage of all flour, dried food, pet food etc. should be within a glass or plastic air tight container so that if there is an infestation within those items it will not spread.
  • Consume older foods before purchasing new items to keep your food storage to a minimum. Products purchased in high quantity have more chances of being infested due to them being around for longer periods of time especially if not stored correctly in air tight containers.
