It's true: Rodents Will Chew on Your Car's Wires

Chew on this. Your warm car engine may also have a warm rodent nibbling on the wires.

"I had to replace some wiring due to rabbits chewing," a Times-Call reader said on Facebook.

"There is apparently an epidemic with squirrels and rabbits chewing electrical wiring and so forth under the hoods of cars," another called into the TC-Line on Jan. 4.

Not quite an epidemic, local mechanics say. But far from uncommon.

"It is a fact," said Scott Nichol of Hitek Professional Automobile Repair, who says he gets six or seven cases of rodent damage a year. "It is a cold, hard, nasty fact. Summertime, wintertime, fall, it doesn't matter. ... The more squirrels you have in an area, the more you see things like this."

Travis Paswaters of Hayes Automotive said he tends to see it a little more in the winter. Squirrels and mice aren't specifically looking for your wires, he said, they're looking for a place to nest -- and in the winter, a recently parked car that sits for a while provides a perfect home.

"We pull nests out of air boxes and intake valleys all the time," Paswaters said. "And if they get down and chew something you can't find, you can get a pretty nasty gremlin. One, I remember, chewed the ignition coil wires. The car would run rough because one of the cylinders wasn't firing."

And sometimes it can add up to more than just a rough ride. Last May, a car caught fire and burned; police later determined it was because of a squirrel nest in the engine.

"If they chew up the wiring, you can have a car-becue," Nichol said.

So what can a driver do?

First, keep the car in a garage if you can. You can't close off all the entryways a rodent would use -- they're openings that the car needs -- but putting the vehicle inside makes it less likely that squirrels will pay a visit. Mice may still be a risk, though, Nichol said, especially outside of town.

Second, open up the hood and check the engine regularly, Paswaters said. If you find twigs, bits of leaves or other nest-building material, you might just have a visitor. Having the oil changed regularly will help, too, he said, since the mechanic will be alert to signs of trouble.

One common home remedy is to use mothballs or paint the wires with Tabasco sauce to discourage chewing. That can work, Paswaters said, but it can also have unpleasant consequences, since the fresh air intake is near the core of the engine.

"It'll make the HVAC unpleasant," he said, referring to the passenger heating and cooling system. "You'll be getting that smell yourself."

Nichol advised not to try putting poison down near the car; the risk of a pet consuming it by mistake isn't worth it, he said. The best thing you can do, he said, is not to let the car sit.

"Don't keep it parked for weeks on end," he said. "Make sure the car moves."

Bedbugs Found at Police Station

Police officers across the city are being warned of a frustratingly stubborn enemy that has infiltrated their workplace: bedbugs.

An infestation was discovered last week in the building in Mayfair that houses the Second and 15th Police Districts and the Northeast Detective Division.

The bedbugs came to light after inmates in several holding cells were bitten, said Roosevelt Poplar, vice president of the Fraternal Order of Police, Lodge No. 5.

An exterminator treated the infested areas twice, and the department's administration is closely monitoring the situation, said Lt. Raymond Evers of the Public Affairs Unit.

Joan Schlotterbeck, the city's public property commissioner, said that one inmate had brought the bugs to the building and that an exterminator believed the infestation was confined to three cells.

Those cells have wooden benches that are different from those in other units, she said. They will be removed.

The cell block has been evacuated. Cells will be power-washed, crevices will be sealed, and the walls will be repainted, Schlotterbeck said.

"At this point, we believe we're doing everything we can," Schlotterbeck said.

Poplar said the entire building at Harbison Avenue and Levick Street should have been treated for bedbugs. About 500 officers work out of the building, he said, and the bugs may have hitched rides with inmates who were transferred.

"These bugs, they can be carried on people," he said. "They can be carried in a car, to another district. The holding cells have people coming in and out all day long. We're talking about potentially thousands of people who could be affected by this."

Officers will be asked to report any signs of infestation. Employees who wish to take extra precautions can wash and dry their clothes as soon as they get home from work, Schlotterbeck said.

Poplar said several officers had told him that they might have unknowingly carried bugs home in their clothing. "These guys are under enough stress as it is without worrying about taking bugs home to their families," he said.

The bedbug resurgence began about 10 years ago in hotels and apartment buildings in large cities nationwide. The bloodsucking insects are known for resilience. Clothes and other belongings must be heated to extreme temperatures to kill them, and the bugs can hide in wooden furniture or baseboards for a year without food.

Though New York City has been seen as the center of the scourge, the problem is on the rise here. This year Philadelphia ranked fifth among U.S. cities for bedbugs, with New York still in first.
