How can you best pest-proof a loading dock door to prevent flying insects from entering?

Installing an air curtain at a loading dock door is an effective method for pest-proofing against flying insects. An air curtain is a device that creates a controlled stream of air across an opening, which helps to block insects from entering while allowing for easy access for personnel and equipment.

The air stream acts as a barrier that makes it difficult for flying insects to pass through, effectively reducing the risk of pests infiltrating a facility. This solution is especially useful in high-traffic areas where doors are frequently opened and closed, as it provides a continuous line of defense without the inconvenience of constantly shutting and opening doors.

In contrast, heavy-duty doors may provide some physical protection but do not actively deter insects, and sealing with expandable foam is more suited for cracks and gaps rather than large openings like doors. Leaving the door open does not prevent pest entry at all and would clearly contribute to an increased risk of infestations. Therefore, using an air curtain is the most effective method to prevent flying insects from entering through a loading dock door.
