Rentokil RKLFM89 Beacon Mouse & Rat Rep Dual Action

I had a mouse scratching in my living room ceiling recently so bought 2 of these ....one I plugged into a socket in the living room....and the other in a socket in the room above the living room ..... and within a day....no more scratching.Then two weeks ago in a bedroom in another part of the house there was again scratching in the ceiling.I bought another repeller and plugged it into a socket in the bedroom....once again within a day no more scratching.So on the basis of the evidence I have so far ...they seem to work.Only slight negative is I wish the nightlight could be dimmed or even switched off because it's rather bright and the ticking sound they emit can be a bit noticeable say in quiet locations....I've now grown accustomed to the sound so no big deal really.

This is the second one of these that I have bought as the first one stopped working after 2-3 years. The first one stopped the mice in our farmhouse immediately and has kept it clear for the whole period that it has worked. The second one has not yet got rid of the mice, although there is less evidence of them. I have also put down the old fashioned mouse traps and caught one mouse not far from the unit. The current mice seem to be a bit wiser, as they have removed cheese without getting caught, so perhaps second time around, removal is going to be more difficult.

The constant ticking is very annoying. The green light is very bright when the lights are out, so it's not something you can have in your quiet spaces at all!Pest control worker said they are just a gimmick, for people's peace of mind. I tend to agree!

After trying every method to chase our little friends from our home, we decided to give these a go. They have been amazing and so far we are rat free, we have two as you need one on each ring main. Wished we had tried these first! Highly recommend

Well, I am not sure it works as I have not entered my loft since install. That said, I have not any evidence that rats or mice have returned, so that good news

Just does not seem to work. Mice still run amok

We live in a relatively new house but had a mouse problem. For a few months we heard scratching noises in the walls, I found some mouse faeces when I was cleaning behind a book case and top it all of, saw a little mouse scurrying around in the living room. I did not want to trap or kill any mouse so I found Rentokil Beacon Mouse & Rat Rep Dual Action as a less lethal way of getting rid of mouse. I had this on for about 4 months and all mouse activities have seized. However, when I looked at the quarterly electricity bill, I was a bit shocked! The electricity usage was the same as the previous quarter except for this deterrent so I switched it off. About three months have gone now and we have not had a single squeak or scratches from mouse so this seemed to have done its job. I couldn't give a full five star due to its high electricity consumption.

Customers who expect instant results from devices like this may well be disappointed. I live in a very old house surrounded by fields and generous populations of field mice voles and even rats. I have two lofts and an ultrasonic device in each, always on. Mouse activity? Yes, occasionally but nests? No. The latest purchase for which I am writing this review is in the garage to dissuade 'visitors' from nesting in my car engine which is a trick they have just tried, for the first time. This will most likely stop them on the evidence I have from using such kit for the last fifteen years, at least.So my experience and advice is, be patient. Mice may still turn up in various places but they will not stop long and are exceedingly unlikely to nest with a suitable ultrasonic device in use nearby. They learn to avoid the area. This Beacon product is too brightly lit for bedrooms etc I think but I expect it will join the other US devices I have in deterring mice NESTING, and I don't sleep in the garage so the light on the device is not a problem.
