PestBye Cat Repeller Review

4.0 rating

This is a review of the set of two Pestbye battery operated cat repellers. Although it is available as a single unit, the double pack was only £10 more than the single so I went for the two pack option.

The first thing that you notice about this Pestbye cat repeller is its size. I’ve included my coffee and shades in the photo so you can see just how small it is.

They are the smallest motion detector type cat repeller I have tested so far. Very compact and square shaped rather than the tall cylinder design other manufacturers favour, they are ideal for hiding away on the back of a post or by the side of your lawn via the supplied metal stake.

First Impressions

Below is a quick ‘what’s in the box’ video I made for anyone interested.

Setting Up

The downside to the small size of the Pestbye unit was fitting the plate that covers the battery compartment at the back of the device. It is held in place by 4 very small cross head screws and they are tiny enough to be considered fiddly.

Those back screws are tiny

They also take some screwing in the first time due to the tightness.

I assume the pre-drilled holes are much smaller than the screws to ensure a good water tight seal. Be aware, you will need a good quality small cross head screwdriver to drive them home and the 2 nuts and bolts that hold the metal spike in place are no less fiddly than the screws.

The up side to this is that the backing plate seems to be good and tight thanks to the rubber seal that is on the inside of it so water ingress should not be a problem.

Pestbye Frequency Settings

A unique feature for a cat repeller in this price bracket is the frequency adjustment dial on the front. What I really like about this is that if it doesn’t appear to be working on the cat doing its business in your garden you can adjust the frequency until it does have an effect.

Like us, a cats hearing range diminishes with age so all is not lost with the Pestbye cat repeller if it first appears to be not working. The manufacturer says a frequency setting of 3, 4 or 5 is best for cats but I found 5 was most successful.

The other dial allows you to adjust the sensitivity. The maximum range of the infra red motion sensor is supposed to be 7 metres but in my tests it was more like 10. The lowest range I could get it set to was just under 4 metres but that was with me waiving my arm at it. A sneaky cat in stealth mode may well produce other results.

After the disappointment I had with the PestBye Jet Spray Repeller I wasn’t expecting much from this offering from the same manufacturer. I’m pleased to report though that I was pleasantly surprised at both the build quality and the performance of this device.

Does The PestBye Cat Repeller Keep Them Away?

I’ve only had them set up for around a week so I don’t yet know if I will have to periodically move them around so cats don’t become complacent as I had to with the Mega-Sonic but so far they have performed excellently.


Not long after this review a friend asked if I could do anything with his Mothers garden. She was getting on a bit and it was becoming hard work for her to clear the fouling from her front garden.

I set up both these Pestbye cat Repellers for her and am happy to report they worked long term without having to be moved.

Whenever I’m testing a new cat repeller I always switch off my trusted Contech Scarecrow and Catwatch Ultrasonic Deterrent and unlike some of the other tests I’ve done, on this occasion there has been no cat poop left during the 1 week test.

At around £30 for the 2 pack option it offers great value for money and is ideal for those with a problem in both the front and back garden or for those with a larger area to try and protect.

The size and shape means that they are very unobtrusive, again ideal for those wanting to protect a front garden where a more obvious device may upset your cat owning neighbour.


  • Fiddly to set up
  • Each unit requires 4 AA batteries
  • No mains power option (get some rechargeable batteries)


  • Excellent value for money
  • Seems well made and durable – should give several years service
  • Adjustable frequency enables you to fine tune
  • Small and unobtrusive

There are over 3500 consumer reviews left by buyers of the Pestbye cat repeller with just over half giving it full marks of 5 out of 5.

I’m going to give it 4. While the Pestbye works, it’s not as well built as the CatWatch.
