How To Keep Rats From Eating My Cables?
An anonymous reader writes "I am curious to know what vermin prevention/eradication methods are used in other locations. I am working at a dealership and we have an exterminator man who puts out glue traps and bait stations, but they still come and eat my cable. The latest was a couple of fiber runs — very expensive. I have threatened my boss with a cat for the server room (my office), going so far as to cruise the local Humane Society's website and eye-balling a nice Ragdoll-Siamese mix. Even if I do feel like dealing with a litter box, cat hair in the equipment and pouncings on my keyboards (and I'm not sure I do), that only covers the server room. We have multiple buildings on the campus which get locked up to prevent theft, but it isn't secure enough to keep out the critters and the latest chew spot was in the ceiling. Any ideas?"
Rats and mice don't eat cables...They chew the insulation off to make their nests...or if it happens to be in their way. So your best be it to figure out what the hell they're eating, and shut down their food supply. They'll move on shortly thereafter.
The word "campus" may put paid to that notion, however. Campus implies lots of people, lots of garbage, and lots of space. God help you if it's a college campus, the promised land of vermin the world over, where bulldog sized rats subsist on half a cheeseburger out of the dumpster. If that's the case, then there is no way you'll be able to shut off their food.
Introducing predators isn't necessarily a bad idea, but its a measure that can, in no way, co-exist with traditional methods of poison and trapping. Your predator will likely set off the traps and poison itself on the bioaccumulated toxins in the bodies of its prey. If you do get a cat, better feed it a bunch of activated charcoal with its kibble.
Which brings us to poison and trapping. It's not that they don't work. They work GREAT. If they're not working, it means you're not using enough. You need to come to the budgetary equilibrium where the amount you spend on extermination makes sense based on the cost of cable replacement.
So if you can't shut off their food, and you can't stomach the thought of your kitties/ferrets/snakes keeling over dead from poison every month or two, you're going to have to up the extermination.
ad logicam Claiming a proposition is false because it was presented as the conclusion of a fallacious argument.
And if you can't "afford" conduit, make your own. Garden hose (which rats don't eat through), PVC, etc.
Rat Poison.
Yeah, this is "inhumane" etc, whatever. But that's the only way to reduce the population fast enough to make a difference. Most pest control people want to use poisons, because they know it's the only way that works, but then people insist "omg no! you have to be humane about it!"
Look people. If you want the pests gone, there's really only one option that works.

A couple of Ball pythons in the cable runs, and those rats will be history as will anybody poking around where they're not supposed to...
Cats have been used widely to get rid of rats and mice since the beginning of time. perhaps you should get some of those ?
Not all cats are good mousers, however. It really helps to have one who was properly taught by their mama-cat how to do it.
Bow-ties are cool.
Well, you could always introduce some sort of lizards to eat the rats. And then, after the lizard population explodes you could...uh, well, I'm not sure of the exact steps, but I think it all ends up with gorillas freezing to death in the winter. Or something like that.
Mice are five times more afraid of it.
I don't care if it's 90,000 hectares. That lake was not my doing.

Use high voltage cables and let evolution do the rest.
One of the great reasons why wireless networking and phone technology is popular in Africa is that the copper thieves can't steal the wires. One area I visited often, many years back, had a 25 mile long telephone cable to a phone that never worked. By the time the installation crew finished the installation the first half of the line would be gone and they'd wait for the next year's budget and start all over again...

stop all streaming video of "ratatouille" and blog posts of rat porn, and start serving up content that rats don't like. introduce random packets of lolcat jppegs, maybe streaming video of "mrs frisby and the rats of nimh". you'll soon find the rats aren't as interested anymore at chewing into your cables to get to the content on your network, as they will find it unappealing

Clearly, you need to deploy one or more Rat Zapper Battle Stations
They work great. Rats die humanely. Things that eat rats, don't.
I mean to say, things that eat them don't die, not that they die horrible, lingering deaths.
Well, of course they will die, eventually. But not from this.
I mean, unless they're other rats.
Have you considered dressing up as a minstrel and playing some music? Apparently, that's worked before.
Attack its weak point for massive damage!
These are just regular sized cats with no ninja training.
Rats will happily rip a hole through drywall so don't really care if you block up holes. I blocked up some holes with chew-proof material and the bastards just ripped another hole.
If you have rats inside, then the chances are that they are an overflow population from somewhere else. We didn't have rats in the house until the population built up in the barn and the "turf wars" pushed some of the rats into the house. As soon as we killed a lot of the rats in the barn they disappeared from the house.

You were probably kidding, but I'd like to point out that our local humane society has rules against adopting out animals for the purpose of pest management or hunting.
I once saw a rat run into my garage, and I had heard that cat urine would make them leave so I scooped some used clay litter into a bucket and put it into the garage. I went back the next day and THE RAT HAD EATEN THE FUCKING LITTER!
Rats are real badasses.
Rats can go right through concrete.
You should look at ruggedized stainless steel fiber for you expensive short haul fiber and maybe switch to air gap laser or MMDS wireless for long haul or switch it around.
Both of those are rat proof. check it out http://www.timbercon.com/SS-Cables/index.html
[RIAA] says its concern is artists. That's true, in just the sense that a cattle rancher is concerned about its cattle.
Amusingly, the Denatonium article lead me to the one conerning phenylthiocarbamide and the following quote struck me.
That ladies and gentlemen, is how science is done. Spill some shit and see who falls over dead, goes blind, or starts growing a third arm. Then do studies to "Find Out Why".
I have/had a similar set of problems.
1. I've owned pet rats and know what they can eat.
2. I currently own house rabbits.
3. I have a recurring mouse problem.
So lemme sum up. A rabbit can eat through a 14 gauge stranded copper cord of the sort you'd use for your refrigerator. Guess how I figured that out? Since it's starting at one side it doesn't ever cross both the live and neutral, so it doesn't get electrocuted. It can eat every cord off the back of a computer in under three minutes. Guess how I figured that out? A rat doesn't have quite the toothy abilities of a rabbit but it's fairly close. They can certainly cut through thin copper.
Neither the rabbits nor the rats -- nor my dog -- have been bothered by sprays intended to keep animals from digging/chewing on things. The super hot pepper-derived stuff stopped the rabbits but not the rats, and my dog loves the stuff. The sour/bitter stuff didn't slow any of them down even slightly.
Plastic split conduit doesn't even slow them down. Even when soaked in bitter or hot do-not-chew stuff.
Rats can chew through the side of a lead pipe and crawl through a hole the size of a US quarter. I don't have evidence that they can chew through copper pipe but I wouldn't be surprised.
Reducing food doesn't work. Once they're established, you can't keep the place clean enough. I have no idea how wild mice manage to find nutrition but they do. We keep all our food in sealed containers and vacuum and roomba every other day, and neither the dog nor the sometimes cat deter the mice in the slightest. The mice do, however, drive the dog and the cat completely insane, so if you want to have your predator madly clawing at the wall where it can either hear or smell a mouse, go for it. Both dogs and clawed cats can dig through standard drywall, and then you have a repair to do. (and they remember it and keep trying. Pitbulls are very, very retentive dogs and she'll dig through 12mm thick plywood to get to where she remembers a mouse or rat or squirrel to have hidden, once, six months ago.)
hate to say it but d-con and other awful poisons are probably the best way to go, as far as eradication, and flexible conduit to protect the lines you can't easily replace.
As I said elsewhere, glue traps are probably more evil than poison, and oftentimes live traps are as well, because you don't check them often enough and the animal dies of dehydration. And if you're really lucky the animal will manage to drag the glue trap into a place you can't get to and if you're young and still have good ears you can hear its little high-pitched screams for a couple days before it does die.
Nostalgia's not what it used to be.
Had a customer with a motorcycle shop that had a rat problem. His dog (Jack Russel) went nuts one day, and the owner pulled out a sawed off shotgun and promptly put a hole through the wall.
Exit one rat, four servers, a 440 volt three phase power line, air conditioning condenser, and five twinax runs. Add to damages the vet bill (pellets hit the dog), the doctor bill (pellets hit the owner), and my added expense to replace the servers, bring them from cold to hot, re-running the twin-ax cables, and the $5,000.00 USD (and this was back 15 years or so ago, call it about 8,000 USD today) for, and I quote:
"Extraordinary charge recovery for work location
in a free fire zone without body armor or hearing
protection".
He paid it.
The rat? We buried it without honors or marking it's grave.
Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves.
I say, set up some tripwires for the rats. Bait them with Ratkensteins, or Frankenrats and treats to eat.
When they are scurrying about in the dark, on the wire-mesh-gridded floor, one or more of them trigger/s the 25 or so hidden Tesla coils that pop up like Bouncing Betty grenades. Only, these go vertical with wires, and with dart tips, they affix to the ceiling, as zapping and humming set off a cascade of:
Sqweee-squeee-squee squee, Sqweee-squeee-squee squee (multiplied by how many are getting the charge of their lives)
And, the problem is solved (nightly) with a
ratta-tat-tat.
Of course, mind your voltage, amperage, and other effects, or you'll have body parts stuck on the walls, racks, chairs, and lights. Talk about turning IT/server room into a chamber of horrors.

Don't get just one cat. Get more than one. Get several.
You're right - Cat 1 and Cat 2 will probably do nothing. Most people won't even think they exist. Cat 3 will do most of the work, but won't harrass rats beyond 100 meters. Cat 4 needs motivation - give it a small token, like a ring.
Cat 5 can be faster than Cat 3, but like Cat 3, speed and response begin to attenuate after 100 meters. They start dropping packets, which should promptly be buried in the litter box. In the event that rodents bite back, you should consider shielding Cat 5.
Cat 6 is extremely fast with very little latency, but inflexible and difficult to work with. I use them in my fruit pantry, where rats ate "twisted pears"
