Zero In 60-Day Fly and Insect Killer (Portable Unit, Kills and Repel Bugs, Suitable for Indoor and Outdoor Use in the Home and Garden, Lasts for up to 60 Days)

Seems to last a reasonable length of time.

Giving it 4 stars because I think it works. I just don't know. It's been a colder summer (so windows have been closed more than last year), and just had one fly in and a few fruit flies, compared with last year when we were inundated. So unsure whether the fly problem has dissipated because of this product or because of the weather! I think it's worth a try, anyway.

Absolutely useless !!!Had no effect whatsoever, infact filter was dry as a bone and had no fragrance . Waste of money, don't bother.

Nothing to like. Fly was in the room all night, yuk, and I had to spray it in the morning.

THESE ZERO FLY KILLERS ARE THE BEST I HAVE EVER BOUGHT.I HAVE BEEN USING THEM FOR THE PAST 2 YEARS AND THEY WORK GREAT.WITH MY WIFE HAVING BREATHING PROBLEMS WE CAN`T USE SPRAYS OF ANY KIND,SO WE HAD TO FIND AN ALTERNATIVE AND THATS WHEN I CAME ACCROSS THESE AND GAVE THEM A TRY,IT`S THE BEST THING I EVER DID.I PUT ONE IN THE LOUNGE HALF WAY OPEN AND WITHOUT ANY SMELL FOR THE NEXT 60 DAYS NO FLIES TO BE FOUND ONLY AN OCCASIONAL DEAD ONE.THEY ARE BRILL.ANY ONE WHO IS FED UP WITH SPRAYS THAT ONLY KILL ON USE SHOULD TRY THESE,I WOULD DEFINATLY RECOMEND THEM.GOOD VALUE TO.

At first I thought that these were doing OK in the porch but I take it back now. After a couple of weeks I had to add a second in the porch (lots of plants) and there are still dot-flies in there. It could be that their potency isn't quite the 60 days as suggested.They don't seem to have made any difference in the rest of the house.I think I'll just pop into the porch and give it a squirt of good old spray now and again instead of buying any more of these.

Works very well. We had a massive fruit fly infestation in summer and I used this along with some bug spray, within a day and a half all the flys had gone! This product does not have a nasty smell or have any other impact on the room. My kitchen is very large with a dining area and just one of these did the job. Great value for money, I would recommend.

Used this item before but paid double the price so I am hoping it's as good, we have loads of houseflies in our front room no idea how they are getting in I don't like using fly spray because of the smell, I will write again with an update.........thanks for fast delivery
