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."

Rats Infesting Food Store Prompt Inspector Visit

A cellphone video of rats taken by a passerby at a Vancouver grocery store has prompted a visit to the business by Vancouver health inspectors.

Matt Johnson was walking along West Broadway Saturday when he looked through the window at Kitsilano Natural Foods and saw large rats crawling over food and knocking over containers inside.

Johnson said he was with a female friend who started screaming at the sight.

“There were rats all over the place," he said.

Johnson pulled out his phone and started recording because he thought people wouldn’t believe it when he told them about the bizarre scene without visual proof.

"They were going through the produce, they were running up and down the walls. They had knocked down cans of stuff. It was a big mess.”

Health inspectors were notified about the video, inspected the store Tuesday, and have spoken with the owner about dealing with its rodent problem.

The rodents are a common problem in Vancouver, but if an infestation becomes too severe, inspectors can shut that business down, according to Trudi Beutel, of Vancouver Coastal Health.

"There has to be a wholesale infestation,” Beutel said. “And we have to believe there has been no due diligence on the part of the owner to correct any of the issues that have been brought to light over the course of the investigation."

The owner of Kitsilano Natural Foods, Ben Huinh, said Thursday that pest control technicians were sealing his building and getting rid of the rats.

Huinh said customers shouldn't be worried.

“Our policy for our goods is when in doubt, throw it out. So if we see anything that appears to be tampered with by rodents or anything we will discard of it," said Huinh.

Fall is the time of year that rats become more of a problem, as they seek warm places to go and food to eat, so they can be hard to keep out of homes and businesses, said Peter Steinfort, of Care Pest Control.

"They are excellent climbers, so they can go in through soffits. They can go through any sort of opening,” said Steinfort. “All a rat needs is about half an inch and that's enough for them to squeeze through.”

Steinfort said home and business owners need comprehensive plans to deal with the problem.

Our customers really do have a sense of humor!!! The call came into EHS that these people have squirrels in their attic. They had them a year early but set some traps, caught a few, and the problem was solved. Sort of! The squirrels came back so we needed to do a free inspection and offer a proposal for humane exclusion.

I get into the attic and find out what he meant by setting traps. I assumed he meant live traps but I was wrong! He set out rat snap traps with some taunting messages on them. “SUCK IT MR. SQUIRREL” and “LET’S MAKE IT A DOUBLE FURBALL” were written on two traps. It is not exactly the right way to do squirrel removal but it did make me laugh out loud! The customer said it was a six month battle against the squirrels last year and it became personal when they were chewing up items they stored in the attic.

We excluded the points of entry around the roof line, installed one-way doors, returned one week later to remove the doors, then completed the exclusion. No need to taunt the squirrels this time, EHS was the winner!

Rat Attacks Baby’s Face

A baby boy left sleeping in his stroller outside a Copenhagen apartment block was bitten on the face by rats this week.

The boy was left sleeping in his stroller in the courtyard of an apartment complex in the center of Copenhagen on Wednesday evening. Apparently this is common behavior in Denmark, despite the cold and other obvious dangers. As soon as the parents discovered the baby’s injuries they called an ambulance and the toddler was rushed to hospital for emergency treatment.

The boy’s father later told reporters from Denmark’s Ekstra Bladet newspaper that the youngster had been bitten by rats on the face, close to his eye. Other residents from the apartment complex also told the reporters that there was a current vermin problem as dozens of rats try to escape the harsh winter conditions looking for somewhere warm to hide.

Rats are known to attack babies, and they will go for the soft tissue areas such as the eyes. There have been more than one case of death caused by rats eating babies.

More Rodents Carrying Hantavirus Found

Six more rodents trapped by County Vector Control technicians last week have tested positive for the sometimes-deadly hantavirus, County officials said this week.

The rodents, four Harvest mice and two California Meadow Voles, were trapped in Fairbanks Ranch and northern Escondido near the San Luis Rey River bringing this year’s total to 16 rodents testing positive for hantavirus, a news release stated. In 2010, a total of 21 rodents tested positive for hantavirus.

“Recent rains have created an abundance of food for rodents, which can increase the rodent population,” said County Environmental Health Director Jack Miller. “More rodents can lead to more hantavirus.” People should never sweep up or vacuum rodent droppings and nesting materials. Instead, ventilate closed areas and use wet cleaning methods with a 10 percent bleach solution or other full strength disinfectant. The best way to prevent the disease is to keep mice out of houses, garages and sheds by sealing all holes larger than the size of a dime, the news release stated.

Wild rodents, primarily deer mice, carry hantavirus. People can contract it by inhaling dust particles from rodent droppings and nesting materials that contain the virus. The virus can cause hantavirus pulmonary syndrome (HPS), which begins with flu-like symptoms, but can graduate to severe breathing difficulties and even death, according to the news release. There is no vaccine or specific treatment for hantavirus and the national Centers for Disease Control and Prevention report that HPS has killed 36 percent of all the people known to have contracted the disease.

How to Avoid Exposure:

• Eliminate rodent infestations immediately.
• Avoid rodent infested areas. Do not stir up dust or materials that may be contaminated with feces and urine.
• Clean up rodent droppings and urine using the wet cleaning method described below.

Use “wet-cleaning” methods to prevent inhaling the virus:

• DO NOT SWEEP OR VACUUM INFESTED AREAS.
• Ventilate affected area by opening doors and windows for at least 30 minutes.
• Use rubber gloves. Spray a 10 percent bleach solution (2 tablespoons bleach to 1 cup of water), or other full strength disinfectant onto dead rodents, rodent droppings, nests, contaminated traps, and surrounding areas and let the disinfectant stand for at least 15 minutes before cleaning. Clean with a sponge or a mop.
• Place disinfected rodents and debris into two plastic bags, seal them and discard in the trash.
• Wash gloves in a bleach solution, then soap and water, and dispose of them using the same double-bag method. Thoroughly wash your bare hands with soap and water.

Near South Side Bakery Closed After Inspectors Find Rats, Unsafe Food

A Near South Side bakery was shut down after city inspectors found something customers aren’t too fond of - rats and food stored at unsafe temperatures.

Mayor Daley’s Dumpster Task Force shut down St. Anna’s Bakery, 2158 S. Archer Ave., Thursday due to a rat infestation and unsafe food holding temperatures, according to a release from the city’s Dept. of Streets & Sanitation.

Inspectors visited the bakery in response to a complaint about rodent activity and found more than 70 rate droppings throughout the kitchen. Inspectors also found St. Anna’s had problems with the temperatures in their walk-in cooler.

Food temperatures ranged from 50 to 60 degrees and more than 400 pounds of food had to be thrown away, the release said.

St. Anna’s was closed for the critical violations of inadequate pest control and for failure to protect foods from contamination. The bakery must correct their rodent problems, revamp their housekeeping and pest control programs and repair their cooler before they can request and pass a detailed re-inspection.

Recently awarded the “Green Buildings Product Seal” from Green-Buildings.com, the Leaf Defier gutter protection system from FXI Building Products Corporation helps improve storm water management, enhance building durability and prevent pest infestations by allowing water and fine particulates to flow freely through gutter systems while keeping leaves and other debris out, the firm says.

Designed with high-performance urethane polymers, Leaf Defier is easily inserted into gutters to ensure leaves, twigs, pine needles and other possible obstructions and animal food sources are kept from entering and clogging gutter systems. As a result, water flows readily through the foam filter insert, into the gutter valley and out the downspout to virtually eliminate overflows.

In addition, recent research within the pest management field has confirmed the potential benefits of Leaf Defier, which if used properly can change conducive conditions away from pests, the firm reports. In fact, Leaf Defier can help solve problems by preventing all forms of pests from entering the gutter cavity, including insects like mosquitoes that breed in standing water or carpenter ants that can build nests in moist wood caused by clogged gutters. EHS is an authorized installer of the Leaf Defier system.
