Frequently Asked Questions
Will NHOU Mouse-Out harm electrical connections?
No. NHOU® Mouse-Out is non-conductive and will not harm electrical connections. Make sure that all connections are made before applying NHOU.
Will it void my warranty?
Absolutely not! Because NHOU® Mouse-Out is an entirely different approach, it eliminates annoying electrical malfunctions and makes the vehicle work better and last longer. While the manufacturers probably won’t admit it, they just have to love NH Oil Undercoating® because it will reduce the number of corrosion related warranty claims they are obligated to pay. It also saves customers the time and aggravation associated with claims against warranties.
Will it drip?
NHOU® Mouse-Out is formulated not to drip. However, minimal dripping may occur if the product is applied heavily. In most cases clean up is simple, Dawn dish soap or Simple Green usually does the trick.

NH Oil Undercoating has the best products on the market hands down! Their rodent repellent , superior creeping abilities and outstanding customer service make this the only company you should deal with for all your undercoating needs!
I parked my beloved Jeep in a mouse infested garage. Of course at the time I had no idea we had a mouse problem to that extent. After just a couple weeks, I pulled it out to change the oil. As I lifted the hood, I heard a little rustling. Turns out I now had mice living in my engine bay! They chewed up wires, tore apart insulation material, and made a nest under the plastic engine cover.
Amazing products! I use the undercoating annually on my truck and it has protected so well against New England conditions. Also their mouse out has done an awesome job after I found mice in my car and my wife’s. After treating critical areas with mouse out they never returned! Thanks NHOU!
