Under the weird but true category, we do occasionally get rodent damaged electronics equipment in for repairs. And it’s not always just the gnawing that causes the damage, it’s also what happens AFTER they eat your wiring (yes, that!).
If you think about it for a second, it’s not strange that these critters would seek out the warmth and possible food sources that are found in most any manufacturing plant.
While we certainly are happy to repair your gnawed-on (or worse) circuit boards, we thought some preventive measures might be appreciated. Having looked into this problem, here’s some interesting facts and advice we collected:
- Rats and mice can gnaw through many tough materials including lead, aluminum, window screens, wood, rubber, vinyl, fiberglass, plastic, and poor-quality concrete and concrete blocks.
- Rats only need a ½” inch opening to squeeze in, can drop 50 feet without injury, burrow straight down into the ground for 36”, jump 26 inches vertically and 48 inches horizontally, swim for a ½ mile, and dive through water traps in plumbing. Talk about an IronRat race!
- Mice only need a ¼” opening to gain entry, can jump 18 inches vertically, and survive temperatures as low as 24 degrees Fahrenheit as long as they have access to food and nesting materials
- One rat needs only ½ pound of food to survive for a week but its waste will contaminate as much as 10 times that amount
- Pipes, augers, conveyors, conduit, fire sprinkler systems, HVAC, underground utility and communications lines, earthquake safety joints, and poorly fitting doors (especially roll-up or overhead doors), are their super-highways into your plant
Now you know why it’s so difficult to get rid of these vermin. To do battle against these tough little customers, here some advice:
- Look for signs of entry – Look for droppings, tracks, gnawing marks (a professional pest management company really is the best for this as they have all of the appropriate equipment)
- Don’t Invite – Keep the area surrounding your plant free of clutter and debris, tall grass and vegetation, open trash, and standing water; and make sure your dumpster is on a cleanable concrete pad.
- Doors should fit tightly – Rodents usually enter after dark so avoid leaving doors open at night and make sure your door bottoms are not dented and damaged and the floor is even so no gaps are available. Use metal thresholds
- Repair damage quickly – Regularly check for and repair cracks or damage to exterior walls, floors, and openings in windows and screens.
- Button –up – Tightly rodent-proof sewer, electrical, communication, water, and gas services, and keep elevator pits clean and dry.
- Control Loading Docks – Get rodent exclusion devices and use automatic door closers; dock bumper pads should be at least 30” high to keep rats from using them as a launch pad onto your dock.
- Installing guards helps – Install guards made of smooth sheet metal that are wide enough and positioned to keep rodents from climbing, traveling or jumping from the guard wherever they are needed.
Rodent/Pest control is a huge subject and you can find more information from the National Pest Management Association, or any professional pest management company.
If your electronic equipment is damaged by pests, it can usually be repaired. Most industrial electronic equipment, including older and out of warranty electronics, can be repaired at a considerable savings over buying new.
If your equipment is still under warranty, contact the OEM about repairs. If it is out of warranty, contact an independent industrial electronic repair center to find out if they are a good fit for your company and your particular repair needs. They should offer free evaluations for your damaged equipment and, if needed, a free quote for repairs (no bench fees!). They should also provide repair reports if requested and a good warranty of at least one year that covers both parts and labor.
