RentokilBeacon FM87 Mouse & Rat Repeller (3pkt)

I'm not sure if it works as I still see the odd rodent.

2 of these plugged in in my front room, one facing the kitchen and one facing the room the the entrance, nothing blocking any of them and they are postioned according the the instructions, my living room is only 3x3.5 yet, sitting on my sofa last night and a little mouse comes scampering out, wandering the room, not for the first time since they have been plugged in, he does not appear even slightly fazed by these devices. And he does not looklike he plans to leave anytime soon, i went for the well known brand thinking it would be worth it, what a waste of money. Try one of the ones with excellent reviews, you might have more luck

Used to get rid of mice in my ceiling space. Used 2 from the floor above and one below also sprayed into the space through a light fitting with rodent repellent. Don't know which product did it but the effect was immediate. Mice hsve gone.

You plug the in but can hear a sound coming from them

Have learned that sonic sound based products do not deter mice. We proved this when we installed a mouse trap next to a sonic device in our loft and caught two on consecutive evenings.Have removed all three products

I bought several packs of these on the recommendation of a friend. Unfortunately its a complete waste of money. The mice are so unfazed by them that I have just seen one sit up less than 6 inches away from one (and yes it was working - red light on and an intermittent, annoying, ticking noise). I cannot put poisin down as we regularly have a pupppy in the house and the ultimate deterrent (a cat) is a no go due to allergies. I had really hoped these would work but its nack to the drawing board - maybe if I draw a picture of a cat and put that out it might work - certainly couldnt work worse than these.

In the spring I acquired the Rentokil FM87 and another pest sonic repeller. Now mid-summer I can report that the purchase is a waist of money and time. I only annoyed living creating in the house is me. The device emits a clicking noise that seems to annoy only me since I have seen my arch-enemy stroll in front of this plastic contraption without a care in the world!In summary, I still have an intruder, I have less money in my pocket and now will call the Terminators in.I hope you all the best in your war against this horrid creatures!

Still got our visitors so not sure these are working. 1/10
