Zero In 90-Day Knockdown Flying Insect Killer Portable Bug Killer Cassette Controls Flies, Fungus Gnats, Fruit Flies, Mosquitos and Bugs - with Built in Date Reminder, White

Firstly didn’t have a clue what you’re supposed to do with the little slider bar to set the date so just put it to the end! Placed it above my extractor fan.Seems to be working finding dead blue bottles in floor and on window sills. Recently moved into a new build and had some tiny flies around the kitchen area but since using this haven’t seen much! Either great product or this UK heat is killing them off!! Would recommend you give it a go,, AAAA****

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

I don’t know if I’ve placed it somewhere odd but I have followed the instructions and it does not seem to work for me. There is a slide tab at back I’ve had that either way and still does not deter the flies

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.

Perfect 👌

It started so well, I thought at first it was going to be very effective BUT it only lasted for about 7 days, it was not a gradual slowing down of effectiveness it literally stopped killing the flies

Blown away with this thought it wouldn't work omg how wrong was i it ran out yesterday haven't seen a fly all month today I have two this works going to buy another now brillant

Absolutely useless, followed instructions as per packet placed in appropriate areas, I bought 2 one for the lounge and one for the kitchen has made no difference at all in either room. Complete waste of money which in the cost of living crisis is not money I could afford to loose, it states it starts working straight away upon placing in a room but after a good couple of weeks I have given up any hope of either of them working. Don't waste your money get a rolled up magazine and practice your aim as it will be more effective if you only seat 1fly!
