Bird-X Solar Yard Gard Solar Powered Ultrasonic Animal Control Device with Motion Sensor & Ultrasonic Sensor, Outdoor Bird Control & Bird Scare Devices, Covers Up to 3,000 Sq Ft (15–25 kHz)

I've been using this product for over 2 years now, I'm quite satisfied! If you're finding that it's not keeping certain animals away, please read the manual. You have to adjust the settings for the type of animals that you're trying to keep away. Also, you shouldn't be hearing this at all. It omits a high frequency sound that only the animals can hear and one that they clearly do not like, this does not affect house pets. I've had black bears walk right by my feeders after putting this up. So again, read your manual and adjust your settings. You'll find this is really a great buy! They only cover a certain area, so if the area you need protected is fairly large, I highly suggest (for effectiveness) you pick up another.

Mainly it did not deliver the expected result, the sensor and the flashing light worked, but the birds (peacocks and rooster) continued to ignore the ultrasonic response. The Solar ultrasonic hardware was too low in height, had to continuously trim the surrounding grass, and if tilted a little the rain water got inside and damaged one of the pieces (not waterproof).

Update It took three plus days to get rid of my neighbors cats comming into our garden. This was costing us money to replace rubber mulch, flowers, and time on weekends to take back our garden. Bird X helped. The suggested frequency was not working for cats. My husband suggested to turn the frequency up high and it worked. You saved our garden. We were thinking about removing our garden and replace with concrete. We live on a cul de sac up on a hill and downhill. However, passers decides to let their dogs poop without scooping it up, we have signs with a camera pointed directly in that area. We bought another one and hid in our hedges and dogs and their owners keep moving. We love animals and don't mind if your dog have to go but its done on private property so have decency to scoop the poop. However, we don't own any pets, so its time consuming and costing us to clean after owners pets. We put down signs and its not neighborly.

The past couple years I've used these for deer and rabbits in Upstate NY, and for armadillos in FL, with pretty good results. But the latest batch I received only lasted a couple months before they failed. It's not the batteries, but the unit itself just stops working. Pretty disappointing. My guess is that qualtiy control has dropped significantly. I'm currently looking for alternative brands.

I had a problem with multiple animals in my front and back yards: * The neighbors' cats loved making a litter box out of my front yard and came nightly to do their business. * Raccoons traveled through my back yard, as if they owned the place, and left their smelly and dangerous poop in my back yard. * Squirrels ran gleefully across my front and back lawns burying the goober peanuts and walnuts that my neighbor faithfully provided to them to keep them coming to his backyard. I was desperate for a solution so I started buying multiple motion-detected ultrasonic devices over the past several years. Of the different brands that I've purchased, the solar-powered Bird-X Solar Yard Guards have been the most reliable. They aren't as fancy as some of the other devices that you'll find on Amazon that include loud audible noises and flashing red lights but I've found that the Bird X are the most reliable. (Most of the other brands malfunctioned or stopped working altogether after a limited period of use.) If you have a decent size area to cover (as I did), you'll need to purchase multiple devices and position them so several devices are always going off at one time over the area that you want to protect. I call these zones Animal Annoyance Zones; they don't harm the animals but they annoy the heck out of them when multiple devices are going off at the same time. So, I'll give you the good news first. Here's what HAS worked with the Bird-X Solar Yard Guards: * They quickly annoyed the neighbors' cats that used to come into my yard — so much so, that now the cats avoid my yard completely. They literally will walk on the sidewalk or in the street in front of my house to avoid coming onto my property. I'm happy to report that my front yard is no longer the neighborhood litter box! * The raccoons took some time. (What can I say raccoons are stubborn beasts!) The raccoons would come through my yard and initially be startled by the strobe lights and then move away from my yard. Later, they would come back and investigate the devices to try and determine what they were and then quickly move through my yard to another location. I found that putting a motion detection device that flashed red lights at night with the Bird X Solar Yard Guards eventually drove the raccoons from my yard. They seemed to have gotten tired of dealing with all the audio frequency and flashing light activity. Now, the bad news! Here's what HAS NOT worked with the Bird-X Solar Yard Guards: * They are useless on squirrels (even when I used the recommended frequency which is different from the frequency for cats and raccoons)! I still have goober peanut shells all over my yard. Yesterday, I went through my front yard and found the neighborhood squirrels literally dug holes in front of several of my Bird-X devices. Clearly, the squirrels appreciated me putting these landmarks out for them so they can locate their buried nuts in the future! So, there you have it: if you're willing to buy multiple devices and position them correctly, these devices can work on some animals. However, if you're using these devices to drive Bullwinkles' friend - Rocky - out of your yard, Rocky is probably not going away anytime soon.

REVIEW UPDATE - 2023: We now have 6 of these units facing every direction around out garden - THEY WORK FABULOUSLY! We actually seem to have a resident woodchuck and his family - he/she doesn't come near the garden and just eats the clover in the grass. We had to get the additional ones because a skunk dug up three of our seedlings that had just been planted early in the season - after putting these in he/she has never been back again. TOTALLY RECOMMEND THIS PRODUCT! IT'S GREAT WHEN SOMETHING ACTUALLY DOES WHAT IT SAYS IT WILL DO! 2022 - Our small garden was attacked by the woodchuck who lives over the edge of our property. We went away for a couple of days and he eviscerated our garden - our string beans that were just starting to produce and our pickles - when we came back we couldn't believe the destruction. We set out traps with watermelon, peanut butter - caught other critters but not the woodchuck - he was too smart! We finally ordered the Bird X Solar Yard Guard and when it came installed it in the garden directly facing the edge of the hill. We had left a trap at the edge of the hill with watermelon. In the early morning we saw something in the trap and figured we would deal with it when we got up. When we got up, my husband said that it was empty!! When he went out, he discovered that what ever animal that was in the trap which was in a direct line of the Bird X unit had chewed through the wire of the trap and gotten out!!! We don't know if the Bird X unit made it crazy or if it was a fluke but ever since we have not had a problem. The woodchuck walks along the area of the hill but does not come to the garden. He even tried to come around from the other side - we had installed another unit by then - and he couldn't come near! So far this is amazing and is working - we finally have growth coming back on the pickles and the new beans we planted are coming up undisturbed!! Definitely recommend this product! IMPRESSED!

You can see by the blue light on the front of the camera that the unit is currently blasting its annoying noise, and the skunk is unaffected, happily standing there eating sunflower seeds that were dropped by the birds. The noise is audible and piercing, and my dog and I were unhappy about my decision to turn it on in the house after installing the batteries, but it did not have the desired effect with regard to the skunk problem we are experiencing. The skunks come in from the right, and are blasted with the starting at least 8-12 feet before where the stinky bugger stands in the picture, and he ambled up to within 2 feet of the unit before tucking in and helping himself to a quick meal. I’ll keep watching, but I think this was an expensive failure. Next, I’ll the motion-activated sprinkler. We’ll see if we have any better success with that. If you decide to try this on your own, the instructions warn you not to aim it into neighboring yards, public areas, or caged or leashed animals. I believe this is sage advice - it’s loud and irritating, just not to skunks. ---- I was feeling bad about giving it such a low score, so I turned the unit up all the way and was hoping for better the following evening. At 10pm I checked out the camera and a huge skunk was there completely unaffacted by the sound. I was still dressed, so I ran out and grabbed the hose and shot the smelly dude from 30 feet away or so, and he ran faster than I have ever seen a skunk move. So in spite of my regret for givnig a low rating to this product, the low rating was well earned. 9/27: We were surprised that the raccoons actually were chased off by the noise. So I upped my review - the skunks were our target for this, but we don’t want the raccoons almost as much, so good on the yard Guard.

Bought it in April 2024 and it seemed to be working somewhat but now at the end of September 2024 it is apparently not working at all anymore. Don't waste your money, It only worked for about five months. It is apparent all of these ultrasonic devices don't last long if they even work at all. I will not be buying any of these devices anymore, really cheap junk electronic components. This was supposedly one of the better ones out there.
