Sentinel Ultrasonic Cat / Bird / Dog Repeller with adjustable frequency

100ft range
Sentinel Ultrasonic repeller with 100ft range

The latest addition to our range of ultrasonic repellers is the Sentinel, our most powerful model yet, with a massive range of up to 100ft. The one huge advantage this model has above all the others is that the ultrasonic frequency is adjustable. It means that the user can change the frequency to repel different animals and also “fine tune” the output for the particular location. For example, if you were to mount the repeller in a large building, such as a warehouse to repel Pigeons, the acoustics inside the property might need the tone to be a little higher or lower than if mounted outside. Simply turn the dial on the base of the Sentinel ultrasonic repeller to adjust the frequency either higher or lower.

The Sentinel ultrasonic repeller produces a pulsating and aggressive ultrasonic sound similar to a siren which a bird, pigeon, cat, dog, rat, squirrel etc, perceives as extremely unpleasant and therefore avoids. Please note that it can only be set to repel one animal type at a time. In other words, it can’t repel cats and mice etc, at the same time because animals have different hearing ranges.

Prikka-Strip Cat & Squirrel repeller / repellent fence spike

We have added a couple of new deterrent products to keep Cats, Dogs and Squirrels away from your garden. They are quick and easy to install and not harmful to the animals at all. The products come in two types. One is supplied in strips for fastening along the top of a fence and the other is called a Dig Stopper, (£10.99) which you bury in the soil. Both types of Prickle Strip are made from moulded plastic that has spikes or “prickles” protruding. The spikes are not harmful, but they are designed to cause maximum discomfort.

If you have a cat that keeps using your flower bed as a toilet, or a dog that keeps burying his favorite toy, the Dig Stopper might be the answer you are looking for.

The Prikka strips will deter a cat from jumping into your garden from a fence. You simply fasten it to the top of your fence with either wood screws or use a silicone sealant that you can get from any DIY store.

How to stop dog barking

OFFUTT AIR FORCE BASE, Neb. -- Norman, a 55th ...

Why do dogs bark?

There are many reasons. It’s a form of communication but it can be a sign of boredom. Some dog barking can be traced to our behaviour towards our canine friends or it can be a natural genetic trait. In many ways we condition them to bark. Think of this, “a barking dog gets attention” and that is what most dogs want. The fact that we might be reprimanding the dog, matters not, as long as the dog is getting what it wants. A dog bark can be a warning, a welcome sound but in many cases, it can be a very annoying noise.

If it’s a neighbours dog, try talking with your neighbour first. You never know, they might be quite receptive and not realise just how much noise their dog is making whilst they are out at work.


Can I stop a dog barking?

It’s natural for a dog to bark, but sometimes it gets obsessive, out of hand and has to be stopped. In most cases you can stop barking or at least, reduce it greatly.

We offer several different methods of dog bark control. These are either by sound and sense (spray) or by stimulation (mild static shocks). Collar fitted devices work well with your own dog, but if your neighbour has a noisy dog, you might want to buy a wall mounted ultrasonic bark stopper to overlook their garden.
