## Questions & Answers

**Q: I don't understand the timer. Do we have to slide anything or does it just automatically work ? Also how should it be placed? Which way round pls?**
A: There is a slide but it’s a reminder of the month to discard it. It does stand up on its own on top of a cupboard. I personally threaded a ‘S’ hook through the top to hang it on a curtain rod ! I did put 2 of them in my greenhouse and believe that during the seedling stages they helped. Reason I got them was a ‘compost fly’ infestation on my houseplants and yes it solved th problem.

**Q: Is it safe for rabbits**
A: This product was totally ineffective. As it is chemical based I wouldn't think it should be used around rabbits.

**Q: How does date reminder slider work**
A: You just move the marker to the correct month that it's due for renewing. But I will say, the flies this was a disco ball and all they did was sit on it and start flying round again. It doesn't work, save your money ,don't bother getting one

**Q: Does anyone know if this works for fleas please?**
A: It hardly works for flies 🪰 never mind fleas waste of money

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good condition.
*by O***A on 11 December 2025*

Perfect 👌

### ⭐ Wouldn't buy again
*by E***E on 18 June 2025*

I have one of these in almost every room. And they have been up for about a week now. Flies are still coming it and not leaving or dying. Safe to say they do not work and are not worth the money

### ⭐⭐⭐⭐ A Low Fly Zone, Rather Than A No Fly Zone
*by C***Y on 18 July 2020*

It's actually quite difficult to assess how effective these units are in a domestic setting. In a room in our house a fly landed on one of these units. When I returned a few hours later having shut the door to keep him in, he was still there apparently unfazed by a unit that was supposed to deprive him of his existence. A resistant species of fly perhaps, or an ineffective product ? who knows. Overall we feel that the fly population is lower, but that could be because of other factors, such as not leaving outdoor doors and windows open and the weather, so can't really prove their effectiveness. Overall, we like the idea of something in the background keeping the flies away, without having to chase them down with fly spray in a dog fight. But can't swear that these units are as effective as they claim to be.
