There are multiple measures you can take to safeguard your network from compromises caused by animals, and many of these measures are product related. Obviously there are additional costs associated with these product remedies. If you follow the one percent doctrine, whereby "you must employ 100 percent of our resources to prevent something that has even a one percent chance of occurring," the economics are no longer justified. It would seem that a threat analysis of your network based on the proximity to various habitats would be a good place to start.

Just as a plumber doesn't show up to fix your leaky sink with just a wrench, network operators should place multiple tools in their toolbox to account for rodent infestations. Let's look at some of the products dedicated to minimizing the threat of squirrel and other animal infestations.

SquirrelGuard™ by Osmose: SquirrelGuard™ seems like a natural choice for this problem. These barriers are V-shaped, which helps act as a roof for your cables that will shield them from many different elements. They help avoid squirrel chews because they create a void between the top of the guard and the cable. Squirrels chew into various materials to grind down their teeth, not for food. So if a squirrel reaches a hollow point, they are further deterred from chewing.
Pedfloor™ by Polywater®: Cabinet and pedestal manufacturers have done their best to maintain a sealed exterior enclosure designed to withstand the elements. The bottom of these cabinets is up to you, but what is an effective way to seal around cables that you may also want to re-enter?
Pedfloor™ is a closed-cell foam product that creates an impermeable barrier that maintains its seal through the seasons. It prevents mice, rats snakes, insects and other animals from entering the pedestal or cabinet underground.
If ducts are not properly sealed, creatures could follow cables right up to the warm cabinet. Remember to seal with duct plugs and Pedfloor™ sealant.
Alternative Cable Jacket by Commscope: For fiber and coaxial cable, Commscope offers an Alternative Cable Jacket that combines years of study to design a jacket that is repulsive to many different rodents. The
jacket is a mixture of capsaicin and Bitrex® to produce a mixture that tastes 45 times hotter than Scotch bonnet peppers, one of the hottest peppers in the world. All that heat, and yet this jacket will deter the creatures without harm.
In this blog from Commscope, Doug Wells goes into further detail on how their cable can stem the tide of rodents attacking cables.

Nevertheless, it is worth careful consideration on how you plan to prevent and respond to such attacks. Your IT department hopefully already has a well developed and tested plan to defeat cyber security threats. How is your war on squirrels coming along?
