rodents in car engine

Hi,
I am not able to have rodent repellent shipped out here to California so I am in the process of receiving granule repellent for cats and dogs. Is this gonna work on rats? And can Ropel be sprayed on fan belts in cars?  Am having problems with rodents in car engine.

Thank You, T.T.

ROPEL can be used on anything. The only issue we've seen is some discoloration when treating certain fabrics. I don't think this will be of any concern when treating under the hood of a car and over the years we've had people use it successfully to stop rats, mice and squirrels from chewing on their vehicles.

Regarding the repellent you ordered; I'm not sure if it will work on rats or mice. Designed for cats and dogs, we know it keeps them away. Though some people have tried it for rodents, I don't know if we have ever heard conclusively if it helped.

One thing we know that does work well is the TRANSONIC PRO ULTRA SOUND. It's got variable settings and works well on both rats and mice. Install one set up with a timer as described in the following video and I'm sure you'll be able to keep them away.
