3M Rodent Repellent Coating, Rat Repellent Spray, Prevents Rat Bites in Engine Parts and Wires, Highly Effective, Leak-Free, Easy-to-Spray, Bitter Taste, No Kill-only Repels (Each 250g, Pack of 2)

Very effective,but duration can not assess,do better use it twice a month

I tried the 3M Rodent Repellent Coating mainly for car wiring protection. The application is straightforward. the spray spreads evenly and dries into a thin, clear layer without leaving sticky residue. It’s designed to discourage rats from chewing cables, and in my experience it did reduce gnawing marks for a couple of months. The 250g pack is enough for multiple applications on a bike or small car engine bay. However, it’s not foolproof. In areas with heavy rodent activity, I still noticed occasional damage, meaning reapplication is needed more often than expected. The smell is strong during application, so it’s best to use in a ventilated space. Also, it’s a preventive measure, not a cure. you’ll still need to keep the area clean and free of food sources. Pros: • Easy spray application; dries clear • Helps protect wires; reduces gnawing • Compact 250g pack; sufficient for small vehicles Cons: • Not 100% effective in heavy infestations • Needs reapplication for lasting effect • Strong odor during use; requires ventilation Bottom line: A useful extra layer of protection for car and bike wiring, but best combined with other rodent-control measures for reliable results.

Got a fake product

good

The 3M Rodent Repellent Coating was purchased with the purpose of protecting the wires of the car's engine from the rats. As 3M products are reputable, I believed I would receive a good-quality repellent. How mistaken I was! I did everything according to the manufacturer's guidelines. I made sure to clean the engine bay thoroughly, let it dry out completely, and sprayed an ample and even layer on all the exposed wires, hoses, and plastic. The product left coating and had a strong odor, which created a false impression that it really worked. In the morning, the very next day after the application, I opened the hood to see how everything went. Not only did rats leave footprints on the places where the coating had been applied, but they also had chewed right through one of the wires that were crucial for the engine there was feces and rat poop in various places frustrated about it.

Very good product. It completely stopped the Rat damage in my car.
