The Best Deer Whistles for Cars: Helping You Avoid Deer While Driving!

Today we will be helping you chose from the best deer whistles for cars.

One of the biggest hazards on the road aside from texting teenagers are deer!

They are responsible for accidents, deaths, and plenty of damage.

Check out State Farm’s US map to see the likelihood of a deer collision in your state.

State Farm also notes that drivers are much more likely to be involved in a deer collision in the months of November, October, and December (in that order).

Unfortunately, deer aren’t very responsive when it comes to traffic and have been known to stand right in the middle of busy roads.

Furthermore, they have also been known to run directly into traffic.

These defensive driving tips are invaluable in preparing for a deer-related issue while driving.

While not 100% guaranteed to work, deer whistles provide some insurance to help you avoid deer while driving.

We certainly recommend using them as they are a relatively inexpensive way to help keep deer away from your vehicle.

Below we will provide you with some of our favorite deer whistles.

Save-A-Deer Whistle

Product Rating

This is by far, one of our favorite deer whistles.

Unlike other whistles that utilize 2 separate units to deter deer, this all-in-one whistle requires that only 1 whistle be mounted.

It uses strong, self adhesive tape to stick to your mounting location.

This is the smallest air-activated unit on the market and measures less than 1 cubic inch in size.

Once the vehicle reaches a speed of 35 mph or faster, the whistle creates a sound that alerts deer to stay away from your vehicle.

The manufacturer notes that deer normally respond to this sound by freezing alongside the road or perking their ears up to look at the vehicle.

This product has been widely successful with over 2 million of these devices sold to date!

Please visit Save-A-Deer’s FAQ Page for more information.

The deer whistle reviews for this product are overwhelmingly favorable.

For the most part, people state that they haven’t had any close calls since installing them and it has given them a greater sense of confidence when driving.

While this result could be merely coincidental, we think the Save-A-Deer Whistle is a worthwhile purchase to help you keep deer away.

There are numerous people that state that it has helped them avoid deer collisions and even some accounts of deer running away from their vehicle.

This electronic deer whistle uses a simulated rattle snake sound to scare deer away from your vehicle.

The product includes all necessary mounting and operating hardware.

This easy-to-use unit is operated with a simple on/off switch. It can also be wired to automatically activate with your headlights or ignition.

Bottom Line

While it’s not a surefire way to avoid deer while driving, we believe deer whistles provide cheap insurance against deer collisions.

The products listed above have received some of the best ratings on the web, therefore we consider them to be the best deer whistles for cars.

Users rave about their lack of deer interactions since installing them and the confidence it has given them while driving.

Our advice is to always drive defensively and follow the tips in the link we posted at the beginning of this article.

If you do decide to purchase one of these deer whistles, make sure that they are still mounted every so often as objects and inclement weather can sometimes cause them to come off.

Furthermore, clean air-activated whistles periodically to ensure that the holes do not become blocked/clogged by bugs or debris.

It’s important to remember that deer are wild animals and may jump into the road suddenly for a myriad of reasons.

We wish you the best of luck in avoiding deer collisions and urge you to drive both slowly and safely!

  1. Okay I drive slow like 30 miles per hour or less threw where I see deer the most and I live in Iowa so I a’m needing to buy and Eckler deer alert hope this is easy as you say to install . Many white tail deer in Iowa and Missouri and very stupid . Run out in front of you or just stand on the road honking at that they just ignore you. Stop and drive on gravel at edge of road and they are gone. How come they ignore a car horn and take action when you drive on the rocks on side of road ?

    • That’s a very good question. Deer seem to be bothered more by some sounds than others.

      We can personally attest to the ease of installation of these items and their effectiveness. It really shouldn’t take you more than an hour total to install.

  2. Deer appear to me to be one of the stupidest animals I’ve ever seen! My car has been damaged 3 times by deer and all 3 times they have ran into me! Thank goodness I have not been hurt yet. There are way too many deer. They are damaging vehicles, eating my garden, and ruining the farm fields. The only good deer is the one in the freezer!
    I’m not so sure the whistle would work. They would just stand there and look around like “duh”….

    • You’d be surprised how many positive reviews there are for deer whistles.

      Although some deer don’t seem to be affected by these whistles, the vast majority seem to head in the opposite direction. I’ve witnessed it firsthand on many occasions.

  3. My husband and I have had deer whistles on our grill bumper for years and always noticed when deer are starting to come out on the hwy they do perk up their ears and run back into the woods. I’ve never hit a deer or even come close but our family members don’t think they work and don’t use them but each have hit one or two deer..So to me the proof is in the stats..I am a firm believer in that they work..Going 35 mph at least which our speed limit on the hwy and surface roads are 35 plus.

  4. Is this work on kangaroos?

  5. does this effect a dog riding in the car.

  6. The Hornet by XP3 Corporation is the best and the most effective deer avoidance system.

  7. So the “Save a Deer Whistle” only “requires” one whistle installed. Wouldn’t 2 be even that much then better just the one? Or would it create a problem?

    • That’s interesting as it’s been our experience that 2 whistles need to be installed. They come in a set for that exact reason.
