ASPECTEK Yard Sentinel Ultrasonic Animal Repellent, Waterproof Ultrasonic Cat Fox Repeller with Motion Detector, Pet Dog Deterrent, Rabbit Rat Scare for Garden Yard Field Farm, 4 Key Remote (UK Plug)

After having problems with crows/rooks and one particular small bird attacking my chimney stack, I ordered an ultrasonic bird repeller from Pest Clear. As that unit produced intermittent sounds, I bought another, so had two in the loft of the roof. This helped to clear the crows and & rooks away, until this spring in 2018. So realising that I needed try additional measures I had no choice to look around for something else. When I say I have no choice, these crows and rooks come to the chimney stack and vandalise it. At varying times from 6am to 7am in the morning from their roosts, they arrive at the chimney pots. There is this ‘bang, bang’ on the brick work as they fervently attack the chimney stack, then then follows crumbling noises and brick dust and pieces falling down the roof. If it wasn’t so serious, to see the damage of the first two rows of brick damaged in that chimney stack, one could relate it to the crows stealing Father Jacks glasses in Father Ted series, or more ominously the film the ‘Birds’ by Stanley Kubrick. So, initially I bought two units of the Yard Sentinel RC Ultrasonic Pest Repeller, setting BOTH to constant, full volume and then put them up in the loft of the roof as I had done with the ultrasonic bird repellers from Pest Clear. . After a couple of days, the neighbours thought at times there was a burglar alarm going off. MORE importantly it scared off these large birds, the crows and the rooks. Each unit goes through a cycle of emitting a variety of sounds, at different frequencies. Sometimes there is silence, so that can be the moment that crows and rooks WILL come back. The crows and rooks are smart, they are persistant as they fly around locally from tree to roof top, etc. Whilst two units could adequately complement each other during those quiet periods, I also knew that the crows and rooks COULD become immune to even the noise from two. So I ordered an additional four units, making SIX altogether in my armoury. SO, in order NOT to annoy or concern my neighbours, THREE units are positioned in one chimney, just above the fire place and another two in another chimney, in a similar fashion (It wasn’t big enough for three). Consequently I have one in reserve. I don’t use the fire places, so I can put these in the chimney safely. I have placed them in the upstairs fireplaces, rather than the downstairs fireplaces. The noise goes right up the brick chimney, to the chimney pots at the top. Trying to break the habits of the crows and rooks was never going to be easy, so I am NOT expecting instant results of them NOT returning. They keep coming back, BUT the noise drives them away AGAIN and AGAIN. The racket that FIVE of these units produces, on a 24 hour constant, FULL volume setting is detering the crows and rooks. It drives them off the chimney stack by giving them an enormous headache... I have read some of the comments from purchasers who state that these units don’t work. They do, it is just that you have to be persistent with using them and IMHO, understanding that you may need more than one... The crows and rooks keep returning, BUT they don’t stay VERY long. Eventually the crows and rooks pattern of behavior, their 'habits', will be broken, so they don’t visit my chimney stack any more. In the end they will forget about it and fly somewhere else. That is how you break the behaviour of anything bullying you, they FORGET about you and don’t bother you ever again! It is an unusual situation to be confronted with, BUT with these units, I believe that I am GOING TO WIN.

Had read the reviews and was doubtful it would perferm but in desperation I purchased 1 anyway - took out of box and read all literature (I purchased for an issue with rabbits we have digging up our lawn). Plugged in the device to set up and nearly blew my ear drums off so turned down the dial for the sound but made no difference. Re-read the instructions which sayes to turn dial right down if you can hear it but mine has made no difference what so ever - also it is on constantly when I have it switched to motion detection only - so should have trusted the reviews and not purcahsed it. Also when you try to go on their website it doesnt let you go in it so found an email address which I have emailed but the auto reply sayes as they are so busy it will be a long to to reply back and they want a video of the issue and clear pictures of the issues youo have - so really no help there either so will be retuning for a full refund. so trust the reviews people and do not purchase and save your time and money

I have owned four of these units for around three years now. They are 12v if you look at the mains adapter and so... I power two off the mains and two from a 110AH flooded 12V battery. The mfr states they draw 5A MAX pr hr, so 24x7 that gives 3 days of runtime (60A). They run year round and mean we can actually have some OKish lawns. Before they were eaten to death with droppings everywhere. The good - they just work and they appear to be pretty resilient to weather. I have actually seen a rabbit run away from the noise when they emit. I run two on a 30 x 15m rectangle of lawn at the top corners firing toward the middle. The other two cover independent areas also quite large. I completely agree with the others about the back case - it's utter garbage and a fight to get it on. With the age the back case no longer seals properly on the two in full sun. I assume it's just the heat softening the material and the frost working on the plastic which I doubt is UV resistant. But for the price, it is what it is - I'll just by more when these fail.

I bought 4, but 1 stopped working after 2-3 months. The seller insists on having a video of a non working unit prior to proceeding with my request for a replacement. I offered to return the failed unit on receiving the replacement. Good product, Shoddy customer service. Still awaiting a satisfactory outcome after purchase in April 2025

This was a godsend....neighbours cats were soiling my lawn

Well after buying this it seemed to work against the local cats but after a few weeks they have now come back - even entering into our yard and merely looking at the flashing LED and ignoring both the sound and ultra-sonic waves... In my humble opinion it is a waste of time... as it is for all motion sensor ultrasonic machines that claim to do the job when they don't... and this includes the RSPB CatWatch as this one (which I also have) does not good either! I'm now going for the wall-top fence spikes fitted into place with chicken wire as these appear to be the 100% deterrent for cats!

We suffered from pigeons continuously fowling our seperate brick walled balconies and actually sleeping there! The sight of this mess was not nice and the smell was absolutely terrible, not to mention the time wasted cleaning it away on a regular basis. So, we searched for a deterrent and initially used plastic bird ban - this worked but become messed overtime and very ugly to look at. Then we discovered the Yard Sentinel RC Ultrasonic Animal Pest Repeller with Motion Detector. We gave it a try, using rechargeable batteries and setting it to motion detect mode on 24hr mode. To our amazement, there was a dramatic reduction in the fowling over the next week on both balconies. After a few weeks monitoring, the mess was virtually down to zero on both balconies. But then one balcony started to be fowled again - this was the one where the Sentinel was not situated and hence not fully covered by the Sentinel. So we moved the Sentinel to this balcony and positioned it so that it pointed towards the original balcony. Lo and behold, this balcony now remained clean, whilst the other balcony's adjacent window sill started to become fowled. Having gone through this exercise, we were now confident that the Sentinel was actually keeping the pigeons at bay - so much so that we bought another one to fully cover the other balcony and surrounding area. So, the Sentinel seems to have worked for us, but only time will tell. As an aside, we love animals and birds and value the motion detector function as this limits the time the unit is active, whilst we covered the strobe light with black tape, and turned the sonic sound volume down to zero so as not to annoy the neighbours.

This product does not work it is a complete and utter con I purchased two as I wanted to put one on each side of the roof about 5m apart my electrician ran a cable to the area in question and we plugged them in We had about 30 pidgeons on each side of the roof and after installing the first box two days later we still had 30 pidgeons. The electrician returned and we turned the box up and fixed the other box this had no effect whatsoever we still have 60 pidgeons on the roof we tried to call but there was no answer An absolute total and utter waste of money I have been with Amazon for 15 years and purchased thousands of pounds worth of product all of which can be confirmed and this is the first time I have ever had to write such a review. It is truly awful do not get sucked into this product.

Su función la hace, no tenemos ni un pájaro, pero eso de ultrasonido...¡solo sirve para los sordos! (con perdón para los sordos) ¡Que escándalo forma! Mi marido lo instaló sin avisar, y parecía que estaban torturando a un pájaro y a eso le sigue una alarma y luego una sirena... eso si, no hay un pájaro que tenga güevos de acercarse, las cosas como son, efectivo es...

Buen producto, sin problema para instalar, desde que lo coloqué no ha habido presencia de animales nocturnos.

Vor allem mit der Fernbedienung eine super Sache ! Vorher hatte ich ähnliche Geräte und die musste ich immer wieder vom Erdspieß ziehen um die Teile ein oder auszuschalten ! Jetzt gehört das endlich der Vergangenheit an ! Ein Knopfdruck auf die Fernbedienung und gut iss ! Die Wirkung ist auch absolut in Ordnung seitdem ich das Teil habe gibt es keinerlei Probleme mehr mit dem Marder und der Katze, die mir immer in der Nacht ständig quer übers Auto gelaufen sind am schlimmsten war es bei Regen ! Dementsprechend sah mein Auto aus inkl. der Kratzer die sie Verursacht haben beim hochspringen oder durch das runterspringen vom Auto . Auch die Antenne hat gelitten da der Marder gerne daran geknabbert hat da wahren auch schon 4 fällig ! Aber gut bin voll zufrieden und es tut was es soll nämlich Plagegeister fernhalten und das funktioniert sehr gut !

We bought it for our outdoor backyard during darkness to expel pests and rats, due to infrastructure and new house are building up nearby, thought the device is unable stops rats completely but it reduces those unwelcome rats activities efficiently.

Hello all, I read many reviews about the Yard Sentinel and their excellent Customer Support before deciding to buy one, but before I did, I called with a few questions and spoke to Tech Support. The gentleman was very courteous, and answered all of my questions. The dogs that I am trying to stop from barking are behind the back wall of a large building in my neighbors back yard, so the Motion Sensor was not going to help me, but I knew that the Yard Sentinel had a 110dB Ultrasonic Blaster that could be set for dogs, so I ordered the model that comes with a Remote Control. This is the same unit that has received so many wonderful reviews by Amazon customers, only this model includes a Remote Control too, so I knew it would be just as effective for me, with an added convenience. I have a small hand-held unit made for Training Dogs, with a Yes and No signal, which I have been using on these dogs (the No signal), and they can hear that one through the wall, so I know they'll hear the Yard Sentinel, which is much louder. I mounted the Yard Sentinel around my Back Door, which is only about 10 feet away from the back wall of the building that the dogs stay behind, with the unit facing that wall directly, and the unit is pretty much out of the weather. I added an electrical outlet to an existing outside light fixture by my back door in a weather-proof housing, so the Power Adapter is near the Yard Sentinel, and is protected from bad weather. For anyone who doesn't know, the Yard Sentinel comes with an AC Power Adapter, or you can run it on 4 C-Cell Batteries. I set the Ultrasonic Volume all the way up, and I turned the Sonic (Audible) Alarm all the way down. So now I can now be in my Home Office, Living Room, Kitchen, or on the Front Porch, and fire off the unit whenever these horribly rowdy dogs start acting up, going on and on for 15 and 20 minutes at a time. I just got it mounted today (March 5th, 2012) and I tried it out shortly after I finished, because the dogs were going nuts with me in the yard behind them as I mounted it - they could hear the leaves crunching when I walked, and that was enough to set them off. I know that it might take a week or two of working with them, because they have been left unattended the majority of the time to do as they wish, and when the owners are home at night, they will let the dogs go on for 15 or 20 minutes before they come out and yell at them to Shut Up, so the dogs (6 of them, including 2 Big Nasty Rottweilers) pretty much do as they wish all the time, and they love to bark and raise H311 at every little noise, all hours of the day and night. Believe it or not, if I rattle a pot in my Kitchen sink while I'm washing dishes, they start up, so I am going to have this Remote Control with me all the time. The dogs are extremely hard-headed, but I think it's starting to work already. After I get these dogs trained, I'm going to move the unit to the front of my house, where birds tend to gather in a very large Magnolia tree and mess all over my car. That's another reason I picked this unit, because it's effective on a wide range of creatures. That and the rave reviews about the Customer Support. Since I appear to be the first to Review this model (at the time of writing), for those who don't know how the Remote works, there are 4 buttons on it. There's a Standby button, which will set to the whole unit into Standby (or set it Active again), so you don't have to unplug it or remove the batteries for times like when you're having a backyard party and you don't want to keep unplugging it or removing the batteries. There's an Ultrasonic button, which sets the Ultrasonic Blaster In and Out of Standby. There's a Strobe button, that sets the Strobe Light In and Out of Standby, and here's a Red "Turbo" button, which will set off all of the units features for 30 seconds, and then the unit resets itself. This Turbo button sets off the Audible Sonic Alarm (which has a Volume Control on the back of the unit), the Strobe Light (which flashes 6 times in 30 seconds), and the Ultrasonic Sound (which has a Volume Control and wide range setting for all kinds of pests), all for 30 seconds, even if they have been set to Standby using the Remote's other buttons. This "Turbo" button is the button that I am using to sound the Ultrasonic Blaster from inside my Home or Front Porch (quite a distance away), and it works great. I highly recommend this unit!!! And if you ever have any problems or questions, Technical Support is just a phone call away. Thanks for reading my review of the Yard Sentinel with Remote Control.
