Cable trays carry control wires and conductors from outside high voltage electrical equipment, through
the building walls, to sensitive controls inside the building. Animals also use these cable trays as access
routes into the control building. Once inside, they can do extensive damage to the sensitive cabling and
equipment.
A simple and effective rodent barrier has been designed that concentrates and maintains Sniff’n’Stop’s
odorant level well above the required 0.2 ppm. This barrier consists of an open-cell sponge, coated on
both sides with Sniff’n’Stop, and sandwiched between flexible layers of barrier film. Sniff’n’Stop’s
odorant is trapped inside the sponge. Application of the barrier is as simple as cutting the sponge to the
desired dimensions and packing it into the opening.
This same coated-sponge technique can be used to directionalize Sniff’n’Stop’s odorant into ducts and
conduits. For this application, only one side of the die-cut sponge is coated. The sponge is pushed in the
mouth of the duct around the cable with the barrier-side out. Sniff’n’Stop’s odorant diffuses down the pipe protecting it from rodent damage.

Duct and Conduit Applications
