View Full Version : Deer Whistles for cars

Does anyone use a Deer Whistle to keep from hitting deer? I've read various things about them - "they're good" on the websites selling them, and "no good" on websites not selling them.

I see so many dead deer on the shoulders of the road this time of year - I know the time is probably coming when I'll have one in my lap!

Yes, they work great.......PROVIDED THEY ARE INSTALLED

Failure to install these whistles correctly is the #1 reason they
don't work as advertized. You can't believe how many of these
whistles I've seen all over a car because the owners think they
know more than the whistles designer. Most good whistles come
in a pair with one side one pitch and the other a different pitch.
Unless they are installed "as designed" forget installing them at

I've run deer whistles on all my vehicles for over 25 yrs and have
seen them stop a deer (and dogs) dead in their tracks when they
picked up the sound. I've had one deer run into the side of my
Suburban when he jumped a guard rail at a full gallop. Nothing
would have made bit of difference there. The local police all run
these whistles to save the county money from deer hits.

IMO these bits of plastic are well worth the money to avoid 90%
or more of dog & deer strikes while driving. Nothing is 100%

One word of caution about these whistles..........
Many come off to wash the car. MAKE DAMN SURE YOU GET THEM
BACK ON AS THEY CAME OFF. Once you mix'em up you're done.

I dont think whistles on your car does anything to stop deer from runing infront of your car then again I cant prove it either I think driving slower in problem areas is going to get you the best results I know where the problem areas around where I live are and if I drive through them I slow down and Ive seen and stoped for alot of deer but Ive never hit one knock on wood

i tend to agree with tightwad. deer whistles have worked good for me. a good investment for about five dollars. antonio

I would see 2 or 3 Deer every morning on the way to work. After putting whistles on both my trucks I haven't seen any at all. So yes, I would say they work.

DW was a claims adjuster and laughed when I bought them....
she said you want to know how many cars that hit a Deer had those on them?

I said, I wonder how many were installed the right way and kept clean of bugs and debris.
To me they work.

Send me $5.00 and I will sell you a magic feather that when properly hung on your mirror will protect you from geese striking your windshield. It really works!!!!! (98.2% of the time) ::) :-* ;D

false security IMO if I put them on my car just because I havent hit one yet I might think they work too but ---no whistles and I havent hit any deer......You know its funny because when I drive by any deer they tend to move away from me to gee I wonder why oh oh I know its because Im in a car ;D .... Ya know I got to thinkin and when I go hiking they tend to move away to huh and I dont even have a whistle I wonder why :)

Ive been wanting an answer to this question for years. To those that say no: Then is there any thing that does work? and why don't you think or know they don't work?

I am not baiting I really don't know what to believe and would like to know.

Is there anything scientific that has been written about this?

I just bought a very expensive truck (well expensive for me anyway) and deer strikes on the road are very common where i live so I am concerned.

Someone once told me not to use them because they claimed that the noise attracted the deer and put you more at risk. Anyone ever heard that?

IMHO, deer see and hear very well. I dont think deer are struck by cars because they dont know the car is there, they get hit because they dont understand the concept of traffic. Therefore I cant see how a whistle would help.

Danna, Please.....re-read my post above.

While nothing is 100% doing nothing will get you 0%.

As to do the "work"......

Why wait? It's a $5 expense that at best will save
your truck and you from harm as opposed to not doing
any possible harm just having them on you truck.

Deer (and many other animals) see only in black and white with
no color vision at all. Deer whistles work due to the animals high
frequency hearing picking up the whistles high pitched sound that
is not a natural sound. Most of the time deer (and dogs) will
stop, look around to find the sound, then retreat when they
don't know the sound.

I would say these do work and in some cases too well.

For any of you living in horse country be very careful driving with these on your car- particularly following a horse trailer. Horses are pretty skitish and these things freak them out. They cannot turn around in the trailer and a 1200+++ lb horse bucking around becasue of an unknown irritating noise behind them is enough to cause quite a sway to the tow vehicle. There are several cases of the horse bucking itself right out of the trailer and landing on the offinding cars hood.

Our neighbor just got thrown by her most tame horse as a car passed her on the street. Turns out they had deer whistles too.

Like all things just be aware that you have these on your car and everyone will be better off.

I forgot to mention that prior to using the whistles, I had hit two deer within a months time..and yes I was watching for them....since the whistles..no deer.

Thanks to those who've used them and have some real information to contribute! I found a good paper on them from one of the sites selling them that showed in a good, scientific test that theirs worked 92% of the time to cause deer to stop and listen & figure out what it was coming at them - usually just enough time to slow them down and miss jumping into traffic.

Trouble was, the test had whistles that didn't work at all, and one that worked 98% of the time. It would have been nice if they had published the names of the products! (I want the one that works 98% of the time, not the one that only works 5%!)

There's still always a chance that a deer is coming too fast, is too distracted by mating, or just isn't in the right direction to hear. But seeing all of those dead deer or big smears of blood on the pavement, and shattered window glass makes me want to try SOMETHING to improve my chances of missing those critters.

I used to have a pair on my ol' Pontiac and though I didn't see a lot of deer, I sure seemed to attract DOGS ;D
