Pest Control Product FAQ’s

How far does the Ultrasonic Pest Control range go in metres as we are not sure how the frequency range works?
Hello Andrea, When the frequency range for Possums is selected on the Ultrasonic Possum Deterrent, the maximum effective range is 14 metres in front with an arc of170 degrees in front of the device.  The range will be less on the sides of the 170-degree arc, say about 10 metres instead of 14 metres.
I am wanting to put this on a rendered surface. Will it discolour the render?

Hello Zoran,

We haven’t had any reports of the Bird Repellent Gel staining rendered surfaces.  Being partially vegetable oil based, the bulk of the Gel will dissipate in time but a black residue can remain.  This can be washed off with water and soap or detergent.

How much power does the possum deterrent use? For example, if run continuously, how often would the batteries need changing? Are you considering adding a solar panel? Also can you please let me know what is the proof this device does repel possums and rats, thanks.

Hi Monica

The device has a light sensor so it will automatically turn on at dusk and off at dawn, and rather than emit continuously it emits intermittently and randomly which saves on power. The 9v device doesn’t use much power and has several power options.

1 ) when supplied with a 240 adapter with 2-metre cord or with the optional 10 or 20-metre 9v extension cords the device will use up to 18 watts when operating and 1.5 watts between emissions

2 ) when supplied with a 12v battery jack to operate off a 12v battery. Power consumption is similar to 240 power, and how long it lasts depends on the size of the 12v battery your using, you can add solar panel if using a 12v battery

3 ) if you use 4 x 9v C torch type batteries, the device goes into power-saving mode and will emit less and 0.07 watts to 0.8 watts, which, and will last about 2 weeks. 9v batteries are normally used as a back up in case of power failure when using 240 or if your 12v battery goes flat the 9v batteries will take over.

We have been using the device for many years with great success. When it comes to proof we can only show you customer testimonials, there are several on the website under reviews on the possum deterrent page. The device comes with a 90-day money-back guarantee  


How many do I need for an area of 1000sqm

Hello Deb

Thanks for your question. The snake repellers would normally be installed along the perimeter of your block to form a barrier to snake entry. If your block was 50 metres long by 20 metres wide you would need a minimum of 4 but 6 would be better. You can also add additional units closer to your house like near any shed or near a clothesline or any entertainment area where children or yourself may gather.


Peter Cundall talks about your Possum Deterrent. Looking at your website I am unable to decide which one it would be, would you be able to advise me? I have wallaby, possums, bandicoots and others inhabiting my garden.

Hi Regina, Peter Cundall uses the CEX device.  The CEX has a long history at repelling possums and is the best domestic device to repel bandicoots and wallabies.  However the CEX does make a low-level sound that you can hear so it is better suited to rural living areas where some buffer from neighbours exists.  If you are in a suburban area or if the device would need to be installed close to your bedroom window, we recommend the Possum Deterrent as it is much quieter.  The Possum Deterrent does a good job on Possums but is not as good as the CEX against bandicoots and wallabies.

I have a dog and I am afraid it will effect her. Can the unit be adjusted so it does not effect her. I am wanting to get rid of possums. Can you turn it on only in the evening when possums come.

Hello Julie. The Possum Deterrent has a light sensor that automatically turns the device on at dusk and off at dawn. The device has some effect on Dogs but only if they are close and in front of it. The ultrasonics won’t penetrate walls, windows etc so a dog indoors won’t be affected.

I have recently installed beams to my rear courtyard and been inundated with doves nesting on my beams leaving bird droppings on my new deck. Would this particular product work? Does the product affect the beams and stained wood? Do you apply it like silicone gel with single lines or horizontal lines?

Yes, this product would work. The Bird Repellent Gel is a non-toxic, non-harmful sticky yellow substance that is impervious to rain and can handle temperatures of up to 80 Celsius.  Bird and possums don’t like the taste or subtle smell of it and most of all they don’t like the feel of it on their feet.  The Gel can be used on any surface.  Being sticky it is best to not use it where you may have inadvertent contact with it.  Best applied in either a spiral circle or zigzag lines depending on the severity of your bird problem.

Can you please explain the difference and advantage of your oscillating ultrasonic frequency when compared to Strayban’s rotating system?

With our device, the frequencies go backwards and forwards through their range in a random manner so no set sound pattern is emitted. Rightly or wrongly my understanding of the Strayban rotating system is it is like a record playing the same sound over and over, you can hear it do the same clicking pattern over and over again.

Is there a special price for purchasing two units?

We have structured our prices so that multiple purchases are competitively priced for the market.

Birds are landing on my outdoor chairs, table and pool fence…would this product be suitable. My concern is putting on my chairs and table and then wanting to use them and them being sticky. would love any feedback. Thanks Jane

The Bird Gel is sticky so we do not recommend it be applied where people may inadvertently come in contact with it as you would get it on your clothes.
