Featuring adjustable frequency settings and PIR sensors, these weatherproof devices provide targeted, long-lasting protection with easy installation and up to 4 months of battery life per set. ## Description Set of 4 PestBye® Battery Operated Cat RepellersThese repellers send out very loud noises at a frequency that cats can hear but is too high for most humans. This will both annoy and frighten the cats but will not affect birds. They are also effective against dogs and foxes. These four cat scarers are an ideal solution for front and back gardens.Battery powered, they are easy to install by pushing them into the ground using the stakes supplied, or they can be screwed to a wall or fence.Why the motion sensor?The repellers come complete with infra-red (PIR) motion sensors which turn the devices 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.BatteriesRequires 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 SettingsThese devices allow you to change the output frequency, enabling you to have the most effective solution for your particular pest problem.Working from left to right (from the smallest dot to the largest)- Cats - Between 3 - 5- Dogs - Between 3 - 4- Foxes - Between 3 - 6- Squirrels Between 2 - 7- Rodents - Between 2 - 7- Insects - Between 2 - 7- Roaches - Between 9 - 11N.B If set on numbers one or two the chances of humans being able to hear this are greatly increased. Review: 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: Alles super immer wieder gerne.

Bestellung, Versandzeit, Preis alles bestens. ### ⭐⭐⭐⭐ Review *by G***E on 13 January 2024* 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. ## Frequently Bought Together - Pestbye Set of 4 Ultrasonic Battery Operated Motion Activated Cat Repeller - Duracell Plus AA Batteries (24 Pack) - Alkaline 1.5V - Up To 100% Extra Life - Reliability For Everyday Devices - 0% Plastic Packaging - 10-Year Storage - LR6 MN1500 - Duracell Optimum AA Batteries (12 Pack) - Alkaline Batteries 1.5V - Up To 200% Extra Life or Extra Power - Meets Demands Of Modern Devices - 100% Recyclable, 0% Plastic Packaging - LR6 MX1500 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/466778966-set-of-4-ultrasonic-battery-operated-motion-activated-cat-repeller](https://www.desertcart.us/products/466778966-set-of-4-ultrasonic-battery-operated-motion-activated-cat-repeller) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-20*
