The Big Cheese Ultra Power – Anti Rodent Lacquer Trigger Action Aerosol – Rat Deterrent & Mouse Repellent, Peppermint Oil Spray - Professional Prevention of Rodent Damage – 6 Months Protection – 600ml

effective and easy to use

First started using this after mice got under our car's bonnet where they chewed stuff and built a nest in the engine air filter box, which didn't help fuel consumption.I spray the foam inserts they chewed and all the cable and hose insulation I can see every 6 months and the mice have so far kept clear.Also used it when rats showed in interest in burrowing under the house. Again, it was enough to make them go elsewhere.

Purchased this to deter rats and it did the job after first use, which lasted for a couple of weeks. After that it wasn't as effective and at times rats reappeared literally only an hour or two after application! Should be a lot better than that, especially after reading the claims made on the packaging! In all honesty it's not a product I could wholeheartedly recommend. You could try it for yourself but that'd be up to you.

I tried all types of Big Cheese sprays including this one but like the others it’s not working at all, rats come shortly after it was sprayed. I’d suggest a more permanent solution rather than wasting money on any spray or ultrasonic plugin sound device.

So far no sign of the rats

Did the job as it should do

Seems to work,but needs to be re sprayed after rain

Easy to use but still remains to be seen if it works as it's the first time I have used it.
