Customer Reviews

No more birds in our entertainment area Review by Inneke
Our entertainment area became home to many different birds. Thank goodness for this device as they have now moved on! Thanks! (Posted on 8/01/2018)
Couldn’t be happier Review by Carol From Sydney West
We have a large house with many different sections which were infested with birds, including the roof.
I bought 3 of these units and pointed them where the birds were coming and annoyingly making a mess.
They have all moved on! Brilliant! (Posted on 7/11/2017)

Cat deterrent Review by Britt
Will it work on cats for indoors kitchen bench top?
Is it inaudible for humans?
ANSWER: Yes it will. It won't harm the cat but it will be irritated by the device if it jumps on the kitchen bench so the Yard Sentinel will break the habit. Put it on the ultrasonic only setting ( volume dial down)and it will not be audible to humans. You may just hear a low volume hissing sound. There is a small percentage of humans ( 4 percent) that may hear the ultrasonics in high frequency. (Posted on 26/05/2017)
Crows Review by Mark
They're in plague proportions in our suburb.
Does this device emit a sound that humans can't hear ? How long will it last in DC mode ?

The Yard Sentinel is both ultrasonic ( inaudible to humans) and sonic ( audible to humans). You can have the sonic turned on or off and the volume can be adjusted.
It will last up to 2 months in DC mode but this varies depending on the brand of batteries you use. A good option is to purchase rechargeable batteries.
