According to this those don't work well:You need a pair of Deer Whistles. I use them on my motorcycle. They run away from the deer whistle. I now have them in my CyberTruck. Less than $7.19 via Amazon. You install two per vehicle. All the guys I ride with on motorcycles have these installed. When we see deer on the side of the road and ride by with the whistles, they don’t stick around.
