## Description

Great prices on your favourite Gardening brands, and free delivery on eligible orders.

Review: Works Well - I have used one of these for years. it works very well in our kitchen, in conjunction with good housekeeping measures. A hungry rodent will put up with the discomfort if it can smell food waste. if it can't smell food it will stay well away. Empty waste bins every day. it says on the packaging to allow up to 28 days for a full deterrent effect to occur. This device definitely gets my vote. Incidentally, the delivery was poor. The driver knocked briefly on our front door. He did not wait for us to answer. He left the package on the ground adjacent to the front door. By the time we opened the door he had gone. This was less than 2 minutes from knocking. He certainly did NOT hand the package to the customer as is stated on the final delivery note.
Review: Who knows? - Who knows if these things work or not. I can't see it repelling active mice because it only emits a single high-frequency bleep every few seconds - but I think it might deter them from nesting in that area, hopefully. After all, they wouldn't be able to sleep with it going all night and day, so would presumably go elsewhere.

## Questions & Answers

**Q: Can humans and dogs hear it?**
A: Switching it on and off in his location he has never reacted to him.  At times he has laid down right next to it.  Two humans in house and doesn't bother either of us.  Very first sound I heard this morning sounded like a neighbours fire or CO alarm.  Recognised the noise like a HF Radio background with a bit or morse code.  Investigation proved the batteries (3AA) were flat and they really were when when tested.  No indication before that battery strength was fading.  Don't know how long this alarm would have sounded for but changed batteries and after first few seconds it silenced.  That was the first time after 6 months of purchase I ever heard any audible alarm sounding.

**Q: How long does it take to work ?**
A: Thank you for your query. The repeller by itself could take up to 28 days to start working to its full effect (this is because rodents can be stubborn to get rid of if they have already nested in your home, as that’s where their ‘scent’ is, and it might take a for them to fully leave, but they will realise and associate that your home is now a discomfort to  them, and they will move out. Please ensure you are using no bait as well, and that there is no obvious food source available for them, as this will entice the rodents back in. Please do not hesitate to contact us with any further queries.

**Q: Do i need  more than one**
A: I don't think these work. I have 2 (a friend gave me one) but we still get mice-have trapped 5 in last 24 hours!

**Q: Why can I hear it when it’s plugged in?**
A: Because it's not very good. 
Mine was fine at first and I could only hear it when I pressed the test button. After around 2 weeks, I could hear a high-pitched sound from the repeller constantly. My solution was to leave it switched on whilst I was at work or in another room so that the noise wouldn't bother me - it shouldn't have been necessary but it did get rid of the rodents (and saved me the trouble of returning the product).

### ⭐⭐⭐⭐⭐ These work I bought one for my attic because I heard mice
*by N***D on 29 August 2023*

It did not work at least at first so I bought another one and place both ends of my attic we have had no mice in 5 months in house or attic. I also sealed up all holes I found near kitchen pipes with wire mesh I recommend this. Recharge the battery's every 2 months
