Yard Sentinel Ultrasonic Outdoor Bird and Pest Repeller with Strobe & Motion Sensor Technology. 

The Ultimate Weather Proof Bird and Pest Repeller irritates intruders by emitting Sonic & Ultrasonic Sound Waves with the bonus of a flashing Strobe light. 

The Intruders are forced to go elsewhere as the sounds irritate them. Fully Programable, Volume Controlled.

The Yard Sentinel offers extra protection against those unwanted pests such as birds, bats, pigeons, crows, ducks, cats, possums, dogs, rabbits and more!

Fully Adjustable Settings, blast them full time or set to the Sensor Dial.

Sonic Noise is Volume Controlled.

This is an excellent option if you wake up each morning to find your garden dug up and your garbage cans overturned or wake to those noisy birds at your window.


The Yard Sentinel is the best option:

1. If you have night time pests on your property (possums, bats) Strobe is very effective
2. If you plan to fix it and forget it (the device will go off automatically on the mode you select) 
3. If you plan to leave it on all day




Weather Resistant:  

The Yard Sentinel’s innovative cover keeps out rain while still allowing for easy access to controls. The Yard Sentinel is weather resistant under most conditions. In the case of extreme weather, protect your product by bringing it indoors.


Customised Control: 
Every pest situation is unique. Our device comes with different modes and selectors to help you target your particular situation:

1. Sensor Mode (Constant standby, will trigger the unit when pests are in range) 
2. Continuous Activation Mode Selector (If pests go out of range of the motion sensor, the device will still be active) 
3. Ultrasonic Frequency Dial (Adjust frequency to target specific pests) 
4. Alarm Dial (Adjustable alarm volume to suit your needs) 
5. Sensor Sensitivity Dial (Adjust the motion sensor from 1.5 to 14 metres)

    we installed this in an undercroft carpoark and a week later we returned and found all the birds gone (swallows) and the cars are much cleaner!!

  2. noisy curlews  star rating

    Posted by barry on 15th May 2016

    the first night I set up the unit there was an immediate effect ,the curlews
    nightly sit under the trees opposite our bedroom window squawking and crying for periods throughout the night.In the next few nights it was obvious that they found there favorite spot no more enjoyable.At times I still hear them in the distance of the nearby properties ,but I have now enjoyed finally! silence and a good nights sleep.I was hoping that it would also deal with the bandicoots that turnover our turf at nights but this was not to be. I find fresh diggings 15 to 20 feet from the unit.But still happy that it looks like the curlew issue has been finally resolved(was my main issue)It would be good if the unit had a longer range and a full 360deg as we have a few acres and the unit only covers a area to one side of our house.

  3. Surprisingly Happy  star rating

    As most I was very sceptical, but our pigeon in the roof issue has improved from 15 pigeons to just 2.We will continue the fight but thanks to the Yard Guard & Strobe we are very close to full success.
