Rodent-proofing at door openings:
a practical structural measure within Integrated Pest Management (IPM)
Structural proofing in modern IPM
Within professional pest management, the importance of proofing is now widely recognized. In virtually every Integrated Pest Management (IPM) programme, the focus is on eliminating access points and structurally reducing risks within the building envelope.
In practice, however, certain parts of buildings remain consistently vulnerable. One of the most common examples is the gap beneath doors.
At BSP Pest Solutions, we work every day with proofing solutions that help professionals improve structural pest prevention. As a distributor of products including Raxit, we collaborate with pest management professionals, technical service teams, and facility managers to effectively address vulnerable points in buildings.
Door openings remain a recurring
vulnerability
During building inspections—particularly in logistics facilities, manufacturing plants, retail environments, and the hospitality sector—it is common to find doors that do not fully seal against the floor. This can result from several factors, including:
· Wear of hinges or door leaves
· Settlement of floors or thresholds
· Manufacturing and installation tolerances in industrial door assemblies
· Intensive use of high-traffic doorways in logistics operations
Even a gap of just a few millimetres can be sufficient for mice to gain entry. Rats require a slightly larger opening, but they also frequently exploit existing gaps beneath doors. From a structural proofing perspective, these gaps represent a typical access point that deserves attention within an Integrated Pest Management (IPM) programme.
Limitations of standard
door seals
In many buildings, standard solutions such as rubber seals, brush strips, or draught excluders are commonly installed. However, these products are generally designed to reduce draughts and noise rather than to prevent rodent entry.
In environments where rodent pressure is present, this often leads to problems. Soft materials can be gnawed through, brush seals leave small gaps between the bristles, and intensive use causes seals to wear over time.
As a result, gaps can reappear, allowing rodents to gain access to the building once again.
Specialised seals for
pest proofing
For this reason, door seals have been developed specifically for rodent proofing at door openings. Raxit products are a good example. Raxit door seals consist of a flexible Santoprene profile reinforced with integrated stainless steel wires. This combination ensures that the seal:
· Remains flexible for normal door operation
· Maintains close contact with the floor
· Resists rodent gnawing
By sealing the full width of the door opening, the system creates a durable physical barrier that prevents rodents from entering the building via this route. This is particularly valuable in areas where doors are used intensively, such as warehouses, logistics passageways, and service entrances, where effective proofing can make a significant contribution to reducing potential entry points.
A broader look at structural
proofing
Although door openings are a common point of attention, potential entry points can be found throughout the building envelope. Examples include:
· Openings around cable and pipe penetrations
· Ventilation openings
· Damaged masonry or mortar joints
· Junctions between different building materials
The Raxit product range also includes solutions designed for these types of applications, such as materials for sealing cable penetrations and protecting vulnerable structural elements where rodents may gnaw their way into a building. This allows structural proofing measures to be implemented at multiple levels throughout the building.
Prevention as a structural
measure
Within Integrated Pest Management (IPM), eliminating potential entry points remains one of the most effective ways to achieve long-term pest prevention. While monitoring and control continue to play an essential role in any pest management programme, the risk of rodent ingress remains if insufficient attention is given to structural proofing.
By addressing vulnerable areas of the building envelope—such as door openings—the risk of pest intrusion can be significantly reduced. At BSP Pest Solutions, we support pest management professionals, technical service teams, and facility managers with practical structural proofing solutions that meet the requirements of modern IPM programmes.
