    Now your home and property are protected by a booming wall of sound that's over 300% louder than The Guardian™ Classic, an improved thermal motion sensor with pinpoint accuracy, a brand new predator call option, and our superior Select-a-Pest™ technology.

    How does it work?

    The Guardian blasts a range of ultrasonic sound, audible sound, and predator calls to scare away a wide variety of pests. Discover why business owners and customers worldwide have trusted the Guardian for over 8 years to get rid of squirrels, bats, deer, raccoons, mice, rats, opossums, skunks, armadillos and more.

    But don't take our word for it

    We'll let the facts speak for themselves. And should you have questions at any time, know that you can speak to a live representative by calling 1-800-657-8214.

    Notable features

    More power. More control. More protection.

    The new and improved Guardian is 300% louder than our gold standard, The Guardian™ Classic. This gives you 3× the security and control over your home and property. All while being completely safe, humane, and eco-friendly.

    Become the hunter

    With our innovative predator call feature, drive away deer, elk, raccoons, and more using predatory wildcat growls. Frighten and disorient pests using the calls of their natural predator, causing them to seek shelter elsewhere.

    Detect pests with pinpoint accuracy

    The new Guardian uses a highly specialized thermal sensor that recognizes movement by picking up changes in heat. This allows the Guardian to activate with the slightest movement of pest animals or people within 60 ft of the unit – while at the same time preventing false activations like leaves blowing in the wind.

    No problem – rain or shine

    The Guardian has been built to withstand both the unforgiving sun and torrential rain. Even after cheaper knock-offs have submitted to the elements due to inferior quality and craftsmanship, your Guardian won't miss a beat.

    Select-a-Pest™ technology

    With our exclusive Select-a-Pest™ technology, now you can get rid of that skunk under your deck without sending your pet bird into a frenzy. No compromises. No trade-offs. Combined with our revolutionary Sound Sweep technology, the Guardian becomes an overwhelming wall of sound that can't be ignored.

  • Where do I mount the Guardian?

    Mount the Guardian at the same level as the pest. If higher, be sure to give it an downward angle.

    Think of the device as a “spotlight.” You want the pests to be in this spotlight of sound and motion detection. The motion sensor needs to be able to detect movement and the sounds need to be heard.

    Checkout the images below for helpful ways to effectively position the Guardian.

    1 Guardian

    Large yard or open area: Position one Guardian so that the sensor is at a right angle.

    Long, narrow yard: Position the Guardian so that pests will pass laterally through the sensor.

    2 Guardian

    Large yard or open area: Position two Guardians so that the sensors are both at right angles and pointing toward general movement.

    Long, narrow yard: Position two Guardians staggered apart to create a parallelogram shape of coverage. This will greatly increase protection.

    4 Guardian

    Large yard or open area: Position four Guardians 120ft (3m) apart so that pests will pass laterally, in front of the sensor. This will provide a huge square of protection.

    Long, narrow yard: Position four Guardians staggered apart to make a larger parallelogram shape of coverage.

  • Setup

    Use the Frequency Dial on the back of the unit to choose the pest you want to repel. Beside the dial there is a list of pests and their dial settings. Here’s a few of the most commonly used settings below:

    • Deer: Setting 1
    • Raccoons and chipmunks: Setting 2
    • Squirrels and opossums: Setting 3
    • Bats, mice and rats: Setting 4

    The Guardian detects motion by using a specialized thermal sensor that detects small changes in heat in front of the unit. This means that an animal moving within 60ft (18m) of the Guardian can cause shift in the level of heat in the area and cause the device to activate. Certain animals (like mice or rats) may be too small to generate enough heat to activate the Guardian when on a motion setting. In those situations we would recommend using the continuous sound setting rather than using the motion sensor to activate the sound.

    In some cases, sources of directed light (like flashlights or car headlights) aimed directly at the unit can contain enough infrared light to activate the unit. Nearby mirrors can also reflect infrared light, potentially causing the Guardian to activate. Keep this in mind when choosing where to set up and install the Guardian.

    Place the Guardian in a central, open area so the sound frequencies can be projected as far as possible. This unit can be mounted on the side of a wall by hanging it from the mounting holes on the back of the unit, or you can place this unit on any type of a flat surface.

    Yes, this unit can be placed under your home. As long as your home is no larger than 6,000ft2 (560m2) one unit should be sufficient. The optional strobe light is highly recommended for repelling pests such as squirrels, raccoons, and bats in dark areas.


    Your pets may be able to hear some of the frequencies projected from the unit. However, if the unit is outdoors and the pets are indoors, this unit will not bother them, as the frequencies will not go through any solid objects such as walls.

    As long as your attic is one open room, no larger than 6,000ft2 (560m2), one unit will be adequate to cover your attic. The optional strobe light is highly recommended for repelling pests such as squirrels, raccoons, and bats in dark areas.

    The sound frequencies can not go through any solid objects such as walls. You would need to place one unit in your front yard, and one in your back yard.

    The lower settings on the unit are audible. When set to a higher setting, you will not be able to hear the frequencies.

    If a pest is just outside the range of the motion detector, or a pest too small to activate the unit is lurking around your yard, you can use the remote control to manually activate the unit. This the sound frequencies up to 100ft2 (18m2) away.


    Armadillos, bats, deer, mice, opossums, raccoons, rats, skunks and squirrels. Results can take 2–3 weeks.

    Note: Be aware that under some situations of extreme drought or other adverse conditions, the pressure on any creature becomes so great that survival overrules any deterrent.

    The Guardian is not designed to kill pests. It is an electronic device that will help repel the unwanted pests and give you a peaceful, damage free home or lawn.

  • Using the Guardian with deer — A four month case study

    Summer 2015 — Courtesy of Biologist Todd Hobein

    Local biologist Todd Hobein is a science teacher for the city of Ashland, Oregon. He performed thorough testing of the Guardian over several months, and recorded his findings in detail. This is an excellent testimonial to the importance of proper placement and installation.

    “I began planting my garden like I do every year at this time. This year, however, I had four-legged visitors I did not plan on. My neighbor had decided some weeks ago to build a fence around his backyard. As a result, the deer no longer were able to use his yard as their runway and decided to try mine instead. In the early part of June I saw my first deer. After a brief look around my garden I immediately noticed that something had clipped the tops off of my Anaheim peppers. No other damage was observed at that time. I decided then to look into pest deterrent options to protect my garden and purchased the Guardian.

    June 15th

    • Observed large doe eating tops of peppers.
    • Upon further inspection, the peppers were too far away from the motion sensor.
    • Moved Guardian from where deer were entering my yard to a location that covered the entire garden area.

    June 16th

    • Watched another deer walk through backyard straight for garden.
    • Deer was clearly irritated by the sound of the Guardian by cocking its head and ears to deflect sound (see Image 1).

    July 1st

    • No deer were observed in my garden since moving the unit.
    • Neighbor observed several deer wandering around the field outside of my garden but did not enter my property.

    July 5th

    Noticed some of the branches on my tomato plants had been eaten that were outside the range of the unit's sensor.

    I observed no new activity or disturbances in my garden, however I did notice that many of my neighbors have gone to great lengths both in labor and expense in deterring deer from their gardens by building fences to protect their plants — when all I needed was the Guardian.

    July 15th

    • Noticed that the peppers had been eaten down again.
    • Upon closer inspection I realized that the tomato plants had grown so much in height that they are now blocking the sensor of the unit for that part of the garden.
    • Raised the unit to point over the tomato plants.

    August and September

    • Upon my return from vacation I found many new piles of deer scat both in the garden as well as outside of it.
    • Amazingly none of the plants had even been touched!

    There were a few times when the deer did get the better of the unit, however, on each occasion this was due to factors that had nothing to do with the engineering of the unit. External factors like plant growth or plants outside the range of the sensor were the main causes of these trials and required simple adjustments for the Guardian to achieve its full potential.

    The protection provided by the Guardian was more than sufficient and allowed me to have one of my best harvests yet from my garden.
