## Description

animal control

Review: Bird problem solved. Cross-hatched angles are more effective for extremely large coverage areas. - We had been unable to use the patio surrounding our home because of bird droppings which we only discovered shortly after moving in. The prior owners must have washed down the decking every time they were going to show the house. Yuckola. We still take our shoes off after coming in the house just in case. We were feeling a bit desperate; the gorgeous trees add a lot of privacy which we are loathe to give up. This machine seems to have worked on the doves as well as the large black birds (crows?) we had been getting. We have this mounted to the eaves of our house which puts the machine at about level with the lower third of the canopy of our very large fig trees. Per the owner reply to our question that positioning should work as the machine covers a 70 degree arc up and down (presumably a 140 degree arc total). We turned the dial to the right just short of where birds/skunks transitions into cats/dogs and it does seem to be working. It's been 72 hours thus far and no more bird droppings. We had been really frustrated and skeptical after we tried the reflective strips and other visual cues to scare birds away because they only seemed to work for a week or two. We've had this up for 72 hours so far and as of this morning, we are giving it 5 stars for being incredibly effective. Will update in a few weeks with additional results. ================= UPDATE 1: First week of use: This machine continues to be effective and humane; and it has made us much happier with this home we recently purchased last fall. We still see birds flit by and maybe even come down to grab twigs for nest building but there are NO MORE huge piles of messy droppings littering the deck every morning. We still get hummingbirds for the flowers, but again, no nesting. All we see now is leaves and twigs which are easy to sweep off and much much much cleaner. This machine is perfect for what we need. We've kept it on the same continuous and ultrasonic only setting just short of where birds/skunks transitions into cats/dogs and the audible noise volume is turned down to zero. We thought we would have to work our way down the spectrum every 3 or 4 days until we found the right setting for the local birds here, but it looks like we got incredibly lucky and hit the correct frequency on the first try. Will update periodically after several weeks and then several months of use with progress updates. If all goes well, we will be recommending this to friends who are getting bird strikes on their windows. Bottom line: Continues to be a 5-star solution. Confidently recommended for overnight bird roosting and nesting problems. ================= UPDATE 2: First month of use: Well, we've had some ups and downs. We decided to try changing the frequency to see if we could get an even broader effect so that pigeons would not even land anymore to get twigs as we were getting the occasional dropping on the deck just from that and it turned into a disaster. After just 24 hours of the changed frequency we started having problems again. Then we changed the frequency back, but it turns out that we had left it unplugged during the change back to the original and forgot to plug it back in. Our deck was a mess. The whole thing had to be hosed down again. And we washed off all our furniture, etc. That was horrible. After we plugged it back in, the droppings seemed to reduce by a lot - about 80% over night; and then completely stopped after about 48 hours. We cleaned everything yet one more time and fingers crossed we've been good ever since. And curiously enough, even the occasional landings seemed to have disappeared. Maybe its because when we made sure the frequency was set for the third time, we must have tweaked it just enough to be perfect. So that was overall a huge win. Now however, we have some new smaller bird that seems to be flitting around and nesting at the margins of our deck - or at least that's what we think from the teeny tiny pile of bird droppings. Still gross but a better problem as the sheer square footage involved is smaller and in an out of the way corner of the decking we can clean more easily. So after some discussion, we've decided to leave the first unit alone as it's working great. We had our first rainstorm and the box is mounted on the eaves where it still gets direct rain and run off from the roof as well and it's still working great. To figure out this other smaller problem, we're going to purchase a second unit and set it at a different frequency to see if that works. Hopefully the new ultrasonic frequency won't cancel out the old one. Will keep this posting updated. Bottom line: Continues to be a 5-star solution. Confidently recommended for overnight bird roosting and nesting problems for doves and large blackbirds and some other large bird of some kind. Purchasing a second unit to experiment with another frequency for smaller birds. ================= UPDATE 3: Full 90 days of use: Make sure all angles are covered! After some accidental re-alignment we figured out that the problem we had been having with smaller birds was due to occlusion and not the frequency; so all of the birds species - large and small - are driven away by the same frequency (continuous and ultrasonic only setting just short of where birds/skunks transitions into cats/dogs and the audible noise volume is turned down to zero). These units work on line of sight so obstructions near the unit can block the coverage area farther out and birds find these safe zones and roost there. We used the second unit then to generate a cross hatch coverage perpendicular to the first unit at the same frequency. The area we are trying to keep clear is about 50 ft deep x 80 ft wide, surrounded by trees about 30 - 40 feet tall. Both units are mounted about 10 feet off of the ground pointing straight out. One unit is mounted at the center of the 80ft wide section. The other is mounted at about 10 feet in from the corner along the 50ft deep section. For us the results were immediate. The resulting invisible cross-hatch of ultrasonic sound is incredibly effective; overnight the deck was completely clear for the first time ever. We are extremely happy to have a droppings-free deck to enjoy year round. This product has made our yard usable.
Review: Are they gone or not? NO THEY ARE NOT!!!!! - I thought I had already posted a review and I was just going to update it. Seems I didn't. So here is the scoop. In my case I guess it is impossible to prove it doesn't work. We just moved to this area and have a very nice 3 seater covered porch swing. Where we used to live there were squirrels, but they never cared about the swing cushion. Two days after setting it up in our new home a squirrel, or more, decided to chew a hole in the back of the cushion and pull out the fiber stuffing. My guess is to make a nest for the upcoming winter. Anyway, I put the cushion in the garage, ordered the Yard Sentinel and when it arrived I immediately set it up and positioned it facing the swing from about 15 ft. away. No squirrels came around. The audible tone would go off several times a day and was so disturbing that I turned it off. Still no squirrels. Then I thought I should put the cushion back on the swing to tempt the critters. Still no squirrels. Maybe they finished with their nest building. Maybe the device works. Whatever, there are no more squirrels and we are happy. Will let you know if anything changes. 9/22/14 Last week I noticed that the squirrel was back and seemingly immune to the Sentinel. I changed the position of the machine, the setting level, the motion control to continuous and placed it back outside. The next day I watched the squirrel climb up on the swing cushion and rip it open. I ran out and chased him away. I tried to modify the setting on the Sentinel, again, but this morning the squirrel just walked across the front of the machine and was unaffected by it. I decided to return the unit to desertcart but was informed that my "window" of opportunity had expired last week. I am now stuck with a device that does not perform as advertised. DO NOT WASTE YOUR MONEY!!!! This machine does not work, at least not for squirrels. I am very unhappy with desertcart.

### ⭐⭐⭐⭐⭐ Bird problem solved. Cross-hatched angles are more effective for extremely large coverage areas.

### ⭐⭐⭐⭐ Pigeon Rejector
*by J***E on May 3, 2026*

Seems to work well to stop disease carrying pigeons from nesting in our neighbor's Ficus Nitida trees. This is right by our kitchen window. Very pleased so far. Seems to be staying away. :-)
