## Overview

The PestBye Ultrasonic Cat Repeller Set of 4 offers a humane, battery-powered solution to deter cats and other pests using adjustable high-frequency sound and a 7-meter infrared motion sensor. Weatherproof and easy to install, it covers a 110° arc and up to 369 sq ft per unit, ensuring customizable, long-lasting protection for your outdoor spaces without disturbing humans or birds.

## Description

Product Description The PestBye Battery Operated Cat Repeller sends out a very loud noise at a frequency that cats can hear but is too high for most humans to hear. This is both annoying and frightening to the cats, but does not affect birds. The repeller is also effective for dogs and foxes. The cat repeller is the quickest fix for cats in the garden. Battery powered, it's easy to instal by pushing into the ground using the stake supplied, or it can be screwed to a wall or fence, we've even supplied all the screws for you! The PestBye Battery Operated Cat Repeller is designed so that you can alter the frequency of the device to target the specific problem feline causing you distress. The frequency dial adjust the sound emitted to enable you to maximise the effectiveness of the device. All cats are different, they have different hearing levels (depending on many factors including age / exposure to noise). The ability to be able to find a frequency effective to your problem cat is what makes the PestBye device stand out from the competition. Why the motion sensor? The repeller comes complete with an infra-red (PIR) motion sensor which turns the device on when a warm body enters the controlled area. This has an important purpose other than saving battery life: researchers have found that cats can become desensitised to the noise if they realise that random sounds are not associated directly with their presence in the controlled area. With the motion sensor, the cat learns to associate the noise with its own movement and is much less likely to stop being afraid of the noise. What area does it cover? It covers an 110 degree arc, to a distance of up to 32ft (10m). Total unobstructed working area of 369sq ft. Unlike most other repellers this allows you to cover a smaller area with the sensitivity dial. The repeller will give you the full 7m if the dial is fully round to the right to decrease the distance turn to the left; this will help to increase battery life as the repeller will cover the distance you want it to. Requires four AA batteries. Battery life depends on how many times the device is activated, but they typically last 3-4 months assuming 10 activations per day. Batteries are not supplied as standard. Frequency Settings The device allows you to change the output frequency, enabling you to have the most effective solution for your particular pest problem. Listed below are the types of animals that this repeller can be used against and the most effective setting for each. Working from left to right (from the smallest dot to the largest). N.B If set on numbers one or two the chances of humans being able to hear this are greatly increased. How quickly will it work? If cats have a habit of feeding and fouling in your garden, it can take 14-28 days to deliver the full deterrent effect. 'Occasional' visitors will usually be stopped within 7 days. If you have a dog, the dog may be affected if it is allowed in the same part of the garden. The sound doesn't travel well through walls and fences, so it won't affect a dog in the house, or a neighbour's dog. Of course, as with all methods involving animal behaviour, we can’t there will be effectiveness in e very s ituation; however, our own experience and the feedback we get from customers suggests that this device is effective in almost all situations. This cat repeller device also do not affect birds so you can keep welcoming them into your garden.

Review: Have been effective as a deterrent - These have worked very well in spite of my initial worry about all the new gizmos as I’d been happy with the older version. It’s hard to know if the flashing light (optional) adds to their effectiveness as it works best at night when I can’t see the cats’ reaction, but if the lack of fouling and bird predation is anything to go by, these work very well. I certainly notice a difference when the batteries run low, although the current batteries have been working for about 3 months, even when having to deal with very frequent visits by both foxes and cats. Heavy bouts of rain do not appear to have seeped into the works and that seems to be an improvement from the previous version. The new instructions also give a better idea of how to adjust the frequencies etc. A fairly expensive but effective deterrent.
Review: Far less "mess" but not 100% effective! - Most of my neighbours have either cats or dogs - I have neither - so an awful lot of the local moggies chose to use my garden as their toilet. {Grrrrr!} I'd tried everything else without success so in desperation decided to give these a go when I discovered this type of ultrasonic deterrent is recommended by the RSPB. They ARE effective but it takes a few weeks to reach maximum efficiency - and even then there may be the occasional "blip" if you know what I mean! However, the initial outlay is not to be sneezed at and, depending on the size of your garden, you may need more than one set. I have a modest sized area of garden front and back but found I needed two sets for maximum efficiency. As to battery life, I find this very good even though I have the motion sensors on mine set to maximum. However, as stated, I do not have any pets (or indeed children!) myself so they are not often triggered. I bought my first set well over a year ago and they are all still going strong. Overall, if you have a severe problem - which I did - I would definitely recommend these if you can afford them.
