Rodent repellent systems

Rodents gnaw cable insulation, and they favour exactly the places a building hides its cabling: raised floor voids, ceiling plenums, cable trays, riser shafts, panel rooms and the space behind kitchen equipment. Damaged insulation is a short waiting to happen, and a short in a closed panel is one of the most common origins of an electrical fire. This sits under fire safety for that reason, not as a pest-control line item.

Ultrasonic and electromagnetic pulse systems make those voids uncomfortable rather than killing anything, which is what makes them acceptable in a data hall, a hospital or a food area where traps and poison are not. They do not clear an established infestation on their own — that is a pest-control job — and we say so rather than selling them as one. Their value is keeping a void that has been cleared from being reoccupied.

Coverage is the whole design. Ultrasound does not go round corners or through a floor tile, so units are placed per void and per compartment rather than one per room, with frequency sweep to prevent habituation. We survey the voids, lay out the transducers against the compartments, install and power them, and check them on the maintenance visit alongside the fire and security systems — together with the cable transits and gland seals, which are what the rodents used to get in.
