How can mice and rats under the hood be controlled ?

We live in the country (woods) and do not have a garage. Mice and rats congregate and build nests under the hoods of our cars. Boxes of D-CON have not controlled the situation. Ultrasonic pest repellant (via a long extension cord) has not kept the rodents away. We are desperate ! Are there any noxious sprays to keep the pests out ? Are there other solutions to the problem other than building a garage ?

    A garage won't help..You can try some "pepper spray", a personal defense product, critters don't like it...Predatory pets can quickly clean up your yard. a "Barn Cat" or certain breeds of dogs are very effective at pest control. Ferrets guarantee a ZERO rodent population..

    Get a cat.
    Or two.

    Cats love to kill mice, and other small animals.

    Plus they purr, and some will even let you rub their bellies.
    Others won't, so be careful until you know which one of the two categories your cat is in.

    You are parking in their environment so either you build a garage and keep the door closed and use traps to get the ones that get in...or use live traps baited with peanut butter/bird seeds...relocate them at least 1 mile away or they will return.....done the latter and it is very effective..just takes time and patience.

    Hi we have the same problem and our cars have been to the shop many times. We've tried traps and poison. You end up killing everything except the rats. We now eliminat the varmints via air rifle w/scope and corn for bait.. It works and can be a fun evening too! For more info go to:

    If you can make the critters think that there's a predator in the area they'll leave. Check with a local garden center and see if they sell a product such as this.

    Do not put bait traps in the car or around the car. That will bring rats... mice.. rodents to the car " On the way to the trap, the rat chewed up your car". Try "Rataway Fragrance"
    spray non-toxic & non-poisonous safe around pets & children. Go to for more details
