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 9)

Good

This spray is very strong but aur beta effectiveness you have to spray it every week that is after every 7 to 8 days so that after certain period rates don't come, this is for sure. Rats do have a monotonous way to hide themselves if you spray it properly every week, rats ignore and don't prefer that area for future.Little bit costly spray as rates do visit again if you stop spraying it for longer time.

Till now no rat bite happened but even before start to use of this product rat never bite even rat marks on engine bay

Ok

There is no use of spraying this for getting rid of rats as this product is not at all effective. Despite of applying inside entire engine bay, the rats still enter inside the engine area as well as A/C vents and pooping on ac filter.

Excellent product

These kind of products difficult to share the review as of they worked you never know it worked. I think it worked as I didn't find rat menace post spray but before that I just only one incident. So I sprayed it as a preventive measure while going to park it for a couple of months

It worked perfectly for me . I sprayed it on the engine bay of my car. It can be used to cover all the parts twice. Will be using it one more time after 6 months
