Itβs tough to believe right now, but white-tailed deer were nearly hunted to extinction. Like the North American bison, they were an attractive source of meat for a fast-growing population. Thankfully, people took notice. In 1873, Maine established the first bag limit β a limit for how many deer a hunter can take in a season. Several other states followed suit.
But poachers would simply go across state lines to hunt, then sell the venison in another state. Things continued to worsen. In 1898, Massachusetts went so far as to ban deer hunting altogether for five years. In 1900, the Federal Government banned interstate sale of poached meat, and the deer began to recover.
Robust wildlife management programs have since paid off. Deer are everywhere. This is good news for the ecosystem, since deer fill an important ecological niche. They graze away at the undergrowth, which cuts down on brush and reduces the risk of forest fires. Their droppings fertilize the soil and provide food for insects. And when they die, the deer themselves become food for predators and scavengers.
Unfortunately, deer and cars go together as well as a lit cigarette in a fireworks warehouse. Deer havenβt evolved to deal with two-tun hunks of metal traveling at 50 miles per hour. Theyβll run out into traffic, seemingly oblivious to the danger. Worse, theyβll freeze up in front of you, which give us the saying βlike a deer in the headlights.β
If youβve ever hit a deer with your car, you know how damaging β and dangerous β a collision can be. Thankfully, thereβs a solution. Deer warning devices, or βdeer whistles,β produce ultrasound as you drive. This ultra-high-pitched sound is too high for humans to hear. But itβs painful to deer, who run away.

Elook Deer Warning Whistle
At first glance, the Elook Deer Warning Whistle is a simple black plastic tube. It measures 1.1 inch long and has a diameter of 0.6-inch. The bottom portion is slightly extended and flattened, giving it a height of 0.7-inch. The ABS material is durable and can withstand changes in temperature. You also donβt have to worry about water, snow, or salt, since plastic doesnβt corrode.
Thanks to the compact size, this device is very easy to conceal. Itβs even small enough to install inside many car grilles. Just make sure itβs not touching the radiator, or it could get damaged. You can also mount it on the bottom of your bumper, where it will be invisible. Point being, youβre not going to spoil your vehicleβs appearance.

You can order it in a 2-pack, 4-pack, 6-pack, or 8-pack. This makes it easy to outfit several vehicles. You can order enough for everyone in the family, and keep all your cars safe.
Audibility
The Elook Deer Warning Whistle kicks in when your vehicle reaches 35 MPH. Below that speed, there wonβt be enough air flow to produce any noise. Think of it like puffing weakly into a trumpet; youβre not going to get any sound. Then again, you donβt buy a deer whistle to prevent low-speed collisions. You buy it to keep yourself safe from a nasty accident.
Above 35 MPH, the whistle will get louder the faster you drive. At highway speeds, itβs audible as far as a quarter of a mile away. Thatβs more than enough range to keep the deer away.

Thereβs one thing we need to be crystal clear about: you cannot hear a deer whistle. The pitch is higher than 20,000Hz, above the range of human hearing. Thatβs the beauty of it. If it were audible to humans, you wouldnβt want it on your car. It would be incredibly obnoxious! As a side note, you donβt have to worry about your dog. They can hear a deer whistle, but itβs not the same pitch as a dog whistle. It wonβt hurt their ears while theyβre riding in your car.
Durability
On the bottom of each Elook deer whistle, thereβs a peel and stick adhesive. Just peel away the white cover paper and press the whistle down on your car, and it will stick. Make sure to clean and dry the area before you apply the whistle. The adhesive wonβt work properly if the surface is covered in dirt.
The adhesive pad uses an acrylic adhesive, which offers a number of benefits. For one thing, it offers excellent adhesion when subjected to wind stress. For another thing, itβs easy to peel off if you want to remove your whistles. It also wonβt leave any sticky residue behind for you to clean up.

That said, this installation method has one major drawback; itβs hard to clean the whistles. Cleaning is important, because dirt and debris will eventually clog the whistle. All you have to do is run some water through it in the reverse direction and clean it out. This isnβt a huge deal, but it would be easier if there were some way to remove the whistles for cleaning.
If youβre concerned about automotive safety, you probably like to be prepared for emergencies. In that case, check out our review of the Imazing IM39. Itβs a powerful, 4000-amp jump starter that fits in your carβs glove box. It also has a built-in flashlight and other nifty features.

DEER SAFE Save A Deer Whistle
The DEER SAFE Save a Deer Whistle is also made from black ABS plastic. However, instead of a simple flat-bottomed tube, it has a pylon-style design. When you look at it, it looks like an upside-down airplane engine. This has some benefits, most notably for aerodynamics. However, it also necessitates a larger design.
The length of 2.2 inches is a non-factor, but the 1.5-inch height limits your placement options. If you have a very large grille, you might be able to fit it. Otherwise, youβll have to use your bumper, or put it on top of your car. On top of your car is probably the best place for most people, and itβs reasonably out of the way.

These whistles come in a 4-pack. As per DEER SAFEβs instructions, thatβs enough to protect two cars.
Audibility
As with the last whistle we looked at, this one will kick in when your car reaches a speed of 35 MPH. DEER SAFE doesnβt give any specific ratings for volume, and we obviously couldnβt hear anything ourselves. That said, deer seem to scatter as the car approaches them, which is not normal deer behavior. Presumably, the whistles are doing their work.

DEER SAFE recommends using two whistles to protect a single vehicle. Given the placement, thatβs probably a good rule of thumb for any deer whistle. With one on either side of the motor, the noise will be that much more widespread. Moreover, two whistles together will be louder than one alone.
Durability
The DEER SAFE whistle adheres similarly to the Elook whistle. Thereβs an adhesive pad on the bottom of the pylon. You peel off a removable paper and stick it on your car. As always, make sure to wash the area first. The adhesive is very strong, and is rated to remain in place even in sub-zero temperatures.

The beautiful thing about this whistle is that you can slide the whistle free of the base. This allows you to remove the whistles and clean them in your sink, then snap them back into place. You donβt have to worry about cleaning a whistle thatβs placed in an awkward position.
Traffic safety is about more than just deer, and it starts with your tires. Underinflation makes your car less responsive as well as reducing your gas mileage. If you want to make sure your tires are always at the right pressure, a portable tire inflator is the ideal solution.

Niteguy Deer Whistle
The Niteguy Deer Whistle is made of black ABS plastic, just like the last two. However, the design is radically different. Instead of being circular, this whistle is flat, with two whistle holes instead of one. It measures 1.97 inches long, 1.57 inches wide, and a mere 0.4-inch thick.
This flat design makes the Niteguy whistle very unobtrusive. Put a couple of them on your carβs roof, and theyβll blend right in. Theyβre even small enough to fit under a bike rack or cargo rack. You can also put them on the top or sides of your front bumper. Theyβll be noticeable, but only barely.

You can order this whistle in either a 6-pack or a 10-pack. This gives you more than enough whistles for most applications. If youβre installing them on a single car, youβll have extras in case one gets damaged. And if you want to outfit the whole family, you wonβt have to order multiple packs.
Audibility
Like both of the other whistles on our list, the Niteguy whistle operates at speeds of 35 MPH and up. At maximum volume, it can deter deer up to a quarter of a mile away. Obviously, this depends on terrain. Trees and hills will dampen the sound, while open ground will let it spread. Regardless, deer will move away from your car.

Durability
Along with each whistle, you get a corresponding 3M adhesive pad. This is a double-sided adhesive with a removable backing on both sides. Remove the backing from one side and stick it to the bottom of the whistle. Then peel of the other backing, and stick it directly to your car. It attaches firmly, but wonβt chip or damage your paint when you remove it.
Our one complaint about these whistles is how hard they are to clean. The back openings are actually in the bottom, just in front of the mounting adhesive. In theory, this area should never get dirty. In practice, it might. When that happens, itβs a headache to clean. Thereβs just not very much space to spray water into, and using a narrow scraper could chip your paint.
Final Verdict
As you can see, all three of these deer whistles will get the job done. But which one is the best one for you? Letβs go over what weβve learned today.
We began by reviewing the Elook Deer Warning Whistle. This is a compact, barrel-shaped whistle thatβs designed to conceal almost anywhere on your car. Itβs audible from a quarter mile away, and it starts working at 35 MPH. It also uses a high-quality adhesive, so you donβt have to worry about it coming loose.
Next, we examined the DEER SAFE Save A Deer Whistle. This whistleβs large, pylon-style design makes placement somewhat of a challenge. That said, the design has a purpose; it makes the whistle easy to remove and clean. We also appreciated the powerful adhesive, which works even in sub-zero temperatures.
Last but not least, we looked at the Niteguy Deer Whistle. We loved this whistleβs unique design, with a flat profile that blends in with the rest of your car. It can be difficult to clean, but it also shouldnβt get dirty enough to matter. Itβs also easy to install, and does a great job of keeping away deer.
