Takeaway: Seems to work against birds to reduce damage to garden veggies.

The pest repeller can be mounted to a wall or post or planted on the stake in the ground. The main body of the pest repeller measures 5.25" x 4.25" x 1.75". It has a solar panel on top for charging the internal battery pack, an ultrasonic emitter in the front, a motion sensor, flashing LED lights, and two control dials. The one on the left controls the frequency ranges it outputs and the one of the right controls the sensitivity or distance the sensor will be triggered. The unit comes with an instruction sheet and a frequency range chart. For example, low frequencies like 3.5 – 20 KHz is supposed to be effective against mice, foxes, and canines while 25 – 34.5 KHz is supposed to deter bats and birds. Each setting emits a particular range of frequencies that is supposed to surprise/annoy the target animals, while setting 5 emits all the frequencies for all critters. The maximum hearing ranges for humans is typically around 18-20 KHz so when in settings 1, 2, and 5 you'll probably hear a bit of high pitched ringing as it cycles through the frequencies. In setting 3 and 4, the unit is silent because our ears can't detect those frequencies.

I'm trying to keep away primarily birds in my garden, so I can choose either setting 3 or 5. I leave it on 5 just in case there are other animals like mice, rabbits, and groundhogs who might want o steal my vegetables (though I haven't seen any lately, but this doesn't mean they're not out there!). When assembled the stake is 12.5" long with the bottom 4.5" inches meant to go in the ground. The main unit simply attaches to the top of the stake and will sit about 8" high. However, you can also use the hanger and attach this to a wall or post so it's higher up.

The unit charges each day from the sun so you don't need to worry about turning it on and off or replacing the batteries often. When the unit is triggered, the sensor will turn red and it will emit the specified range of ultrasonic frequencies twice over the course of 30 seconds. The LEDs will also flash several times during this time to visually frighten the animals, which should be more effective at night time. The range of the motion sensor on the lowest setting is about 8 feet while on setting 5 I was able to trigger it from 25 ft away.

I've had this device in my garden fora couple weeks pointed right at my tomato plants from a distance of about 6 feet. My personal observation is that it seems like there are fewer tomatoes with holes in them from bird pecks. While I I haven't seen any birds in the garden when I tend to it, I only get out there in the evenings which may not be their prime feeding hours. Birds typically they peck small holes in the tomatoes which makes them rot, so hopefully I'll see less of that over the rest of the harvest season. I'll keep an eye out to see if I notice birds hanging out int he path of the repeller which could indicate that they're simply getting used to the sound and lights and no longer afraid of it. With all the rain we've been getting, the repeller is still working normally so at least I know it's waterpoof. As a side note, my cats didn't really seemed bothered by the sounds when it was triggered, some curious looks, but not enough discomfort to move away from it. Perhaps they aren't as skittish as feral cats/animals or maybe they don't like it and are just too lazy to get up and move.
