Customer Reviews

Effective against ducks Review by Barry Ledmar
No more ducks coming to our pool since using this device. It's great! (Posted on 8/06/2017)
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.

will it harm chickens? Review by sandi
I have a problem with crested doves during the day & possums at night, will this harm my chickens?

ANSWER- it will not harm your chickens. It may, however disturb them if you have it pointed in the direction of the coup.
It is an excellent possum deterrent. The Yard Sentinel RC is probably the best however as it has a flashing strobe light for night time pests.
The Yard Sentinel does not affect household pets such as cats and dogs (Posted on 19/02/2017)
Question Review by Sue
Question: I want to scare away birds that are attacking my home veggie patch and fruit tress. However, I also have chickens (the coup is around the trees). Is it safe to use?

Answer: Hi Sue

Thanks for contacting us at Bird Control Australia
Ultrasonics work in line of site, therefore if you are able to have the device pointed toward the bird problem but away from the chicken coup then the chickens will be fine.
The Balcony Guard is an ultrasonic device only so you may wish to try that?

The Yard Sentinel is both Ultrasonic and Sonic( audible to humans). With the volume turned right down it becomes ultrasonic only.

Kind Regards,
Angie (Posted on 2/01/2017)
