Is your car rat free?

What can be more disheartening than waking up one morning for the office and being unable to start the car? And when the hood is opened, finding some serious damages to the internal wirings?!  Investing thousands of dollars while buying a car and again spending more dollars on the repairs is the worst scenario of these days. The repairs give no assurance that there won’t be the same damage again. This is definitely an issue of concern.

Who is the culprit for these huge damages?

Well, these are the tiny creatures which have a habit of chewing everything they come across. Yes, these are the rodents!

The rodents constantly have to gnaw on things to wear their teeth down. Their teeth continually grow, so just like we clip our fingernails, a rat gnaws on things in order to keep its teeth in check. Overgrown teeth are a possible problem for them. They like any surface that they can gnaw on, let the surface be metal, polymer, concrete, wood, etc.

Mice can easily fit through a 1/4 inch hole- About the size of a ring. Rats – a half inch. Nearly every car is susceptible to have small holes or gaps. And the rodents are able to make an entry when through such tiny holes.

The rodents are attracted towards the bright colors and texture of polymers. In the case of automotive wiring, the rodents are attracted because of their taste. Yes, you read it right. The automotive wirings are made of food-grade plastic for a long time now. These make the parts easier to recycle and to meet sustainability targets set by the different government policies. Though ‘green’, these wirings give off a faint smell when warm, which attracts the rodents and they chew up cars. The soy-based content on wiring and fuel lines attract the pests turning vehicles into a moveable feast for pests. as well as rice husks, wood, peanut oil, corn, and other sugars.

Every car owner knows that vermin nesting in a warm engine bay is yesterday’s news. It’s been a problem since the steam age. What is troubling is the growing volume of online stories about rodents chewing up the expensive wiring harness that keep Audis, Hondas, Toyotas, and Volvos running. The damage is not covered by the automaker’s warranty. Also, the assembly is so complex that the mechanics can’t solve the issue and you have to fix the issue by taking it at the car service center.

Toyota rodent/cabling dispute dismissed |

June 16, 2018

A lawsuit by Toyota rodents was rejected after the plaintiffs failed in their claims that soy wires attract rats and other animals and cause them to chew and damage the wiring.

According to the plaintiffs, Toyota switched to “soybean-coated wires” cars, vans, SUVs, and trucks, but the wiring is allegedly defective because it attracts rats and other rodents. Once chewed, the damaged wiring can cause all types of vehicle functions to fail, which is allegedly a security risk.

The proposed class action claims that Toyota is responsible for damage to the wiring that was allegedly covered by the warranty. But the automaker blames the rats for the problem, something that’s not covered by the warranty.

According to the claim, the plaintiffs allege that Toyota’s damage was a “ environmental condition ” and therefore excluded from Toyota’s warranty repair “(19459010) Material Defects .”

The plaintiffs also allege, “ Toyota failed to notify consumers ” that “ it had made the transition ” to the wires coated with soybeans and that the coating “ is more attractive and enticing for rodents and therefore increases the likelihood ” the wiring is chewed.

Mice eating wiring in more and more cars

Woman hit with $1,500 repair bill

By John Matarese, WCPO │ September 5, 2018

If you park your car, truck or SUV outdoors at night, beware.

More and more car owners are getting hit with bills in the hundreds — even thousands — of dollars for rodent damage.

Connie Schwartz of Cold Spring, Kentucky, said she recently spotted something strange in her driveway. The fan belt was laying under her pickup truck.

“A friend came out to fix the belt for me,” she said, “and he said, ‘Oh my goodness, you have a bigger problem.'”

It was much more than a missing fan belt that she faced. Mice or chipmunks had eaten through her entire main wiring harness from the alternator.

“It was chewed all the way to the end, and bare wires were touching metal,” she said.

Years ago this was rarely an issue because automakers used rubber or vinyl wires under the hood.

But lately more and more of them have been turning to soy coatings, as in soy beans, according to several class action lawsuits filed in recent years.

Several ineffective measures are used to stop the menace caused by the pests. Use of ineffective pest repellent sprays and tapes is common. But the essentials used to make these products give ineffective results. Capsaicin is commonly used so as to prevent the damage to cables by pests. The pain receptors of the pests by now have got immune to the capsaicin.

The ultrasonic repeller is used these days. It is a device which emits a frequency that is unattractive to the rat’s ear. They serve to annoy the rat more than anything. These things can work great initially, but rats can get used to the noise.

The solution available with C Tech Corporation to this nuisance is a onetime solution and the need of the hour for the automobile industry. Our products are a blend of green chemistry and smart technology.

Our product Rodrepel™ is an extremely low toxic, low hazard rodent aversive.

Our eco-friendly products do not kill the target species but only repel them. The product is compliant with ROHS, ROHS2, ISO, REACH, APVMA, NEA, EU BPR, and FIFRA exempted.

The product triggers a fear response in rodents thus protecting the application. It causes severe temporary distress to the mucous membrane of the rodents due to which the pest stays away from the application. The product triggers an unpleasant reaction in case if the pest tries to gnaw away the application. After encountering the above-mentioned emotions, the animal instinctively perceives it with something it should stay away from and stores this information for future reference. The fact that certain rodents are repelled is mimicked by other rodents as well. Thus, the other rodents too stay away from the applications. The unpleasant experience is imprinted within the animal’s memory and passed on to its progeny.
