Tip of the Week - Pest Proofing

How pest proof is your food plant, packaging manufacturing plant or storage and distribution warehouse?

  • Mice are able to enter through holes and gaps as small as 1/4 inch.
  • Rats are able to enter through holes and gaps as small as 1/2 inch.
  • Crawling insects are able to enter through minute gaps and cracks.

One method of assessing the pest proofing of your building is to conduct thorough inspections of the exit doors, dock doors and dock leveler systems on bright sunny days. Depending upon the exposure to the sun, the doors should be inspected during different times of the day to provide a complete assessment. If daylight shows around doors, proofing may be needed.

Another method is to conduct an inspection of the exterior of the facility at night. The inspection should focus on light penetrating from the interior of the facility to the exterior, indicating potential pest penetration points. The night time exterior inspection would also be a good time to evaluate lighting on the exterior of the facility that may be drawing night flying insects to your facility, doors being propped open, and other potential security issues.
