Extermination Techniques

When dealing with a Drugstore Beetle infestation, it is important to take prompt action to eliminate these pests and prevent further damage to stored food products. Here are some effective extermination techniques:

  1. Inspection and Identification: Carefully inspect all stored food items, including grains, cereals, dried fruits, spices, and pet food, for signs of infestation. Identify the affected products and remove them from the premises.
  2. Sanitation: Clean and vacuum the affected areas, including cupboards, shelves, and pantry spaces. Pay special attention to cracks, crevices, and corners where beetles may hide. Dispose of the vacuum bag immediately after use.
  3. Freezing or Heat Treatment: Infested food items that can be salvaged can be sealed in airtight containers and placed in a freezer for at least four days. This effectively kills all life stages of Drugstore Beetles. Alternatively, heat treatment can be used by subjecting the infested items to temperatures above 60°C (140°F) for at least 30 minutes.
  4. Professional Extermination: In severe infestations or cases where the above methods prove insufficient, it is advisable to seek the assistance of professional pest control services.
