Zero In Outdoor Fly Trap - Ready-Baited Outdoor Fly Catcher, Twin Pack - Non-Toxic, Insect Trap to Attract & Trap Bugs - Suitable for Garden & Outdoor Use, Lasts up to 2-3 Weeks

So effective and simple. I had one set up in my window box and one on a shelf in my kitchen, both were slowly filling with fly bodies.The bait powder is dumped in the bottle and about 300ml of water added with a little shaking, screw the top on and put the bottles in your chosen locations (ideally in sunlight but out of the wind) . The bait does smell when you are mixing it and the smell gets progressively worse as time goes on - at first it was not so bad, after a week it was awful - definitely an outdoor trap. My kitchen placement was quickly moved outside and soon the smell wafting in from the window box proved too much.The label advises it may take a day for the bait powder to become effective but mine did not wait. The bait lasts about three weeks and more can be bought separately. The bottle/trap design is clever and simple, there is nothing to wear out.When the foul-smelling but highly effective bait has expired, you can buy the replacements or fill the trap with anything you think may attract flies - sweet stuff (sugar water, honey, jam) tends to attract wasps but I have found a little *used cooking oil works wonders - at your own risk etc - just remember 300ml of water is needed as well

We live next to a dairy farm, flies are a problem because we are surrounded by erm.... large flat brown cylinders of processed grass. We had a bit of an Ooni pizza night two Friday evenings ago on the patio outside the kitchen, opened both sets of bi-fold doors, family round, great night. The following morning and the rest of the weekend, there must have been 50 flies buzzing round the kitchen, with little black dots of fly poo everywhere, so we have declared war on the flies.Three pronged attack: UV bug zapper (£50), Zero In Fly Traps (£11 for 2) and old fashioned sticky fly paper s (£12 for 40).The zapper works, it makes a sound like a gunshot when flies explode on the grid, which is very, very satisfying. But it only catches maybe 3 or 4 per day, no matter where we 've located it so far.The sticky fly paper cassettes work, but they do look horrible and we're limited where we can put them without them being in the way. I am still damaged from an incident years ago when I got a quite full one stuck in my hair in the garage.But the Zero In traps: Oh my good lord. Unbelievable, Jeff. In less than a week, both traps, placed about 5 metres from the kitchen in full sunlight, have caught hundreds, maybe thousands of flies each. And wasps, but no obvious bees, so that's all extra positive. I'm convinced that there are less flies queuing up on the bi-folds as a result. Yes, we'll need a full Friday night back-to-back comparison to be sure, but five days in, the Zero In traps have been incredibly effective, way better than expectation and excellent value compared to everything else. Recommended without reservation.EXCEPT... update 2 months later... I bought a second pair of traps, which have turned up and they've changed the design so you can no longer remove the lid. It's gone from being a simple screw-on to a permanently attached thing that you can't remove. There's a bag of bait in there that I can't get to in order to open, and won't be able to empty the revolting fly soup once it's done its work.Further update... The bag of bait is in a soluble packet, so I added water and put it out right next to the old screw top model with a packet of the bait still available via refill. See attached photo for result... after a few hours the old style is successfully doing its thing, but the new style has attracted not a single fly! So apparently they've also updated the recipe, to one that no longer works.I'm going to leave this in the 5 star review section so people who only look at positive reviews will read it, but it's no longer a 5 star re-usable trap, it's a 1 star useless jar of inert liquid. A plastic jar that costs maybe 10p to manufacture on sale for ten quid.Unusable. Heroes to zeroes. How could you have taken such an excellent product and got this so wrong??

Let me start by telling you that I was getting ready to give the worst review in history! I was so mad! So MAD! 24 hours later and no flies inside the trap. I knew it needed 24 hours for activation and reminder for everyone, this works outside,not inside so , as soon as I took the traps out all the flies left my home to follow the scent from these. Not only that but it catches wasps to ,the aggressive type of wasps which terrorised me the whole summer. If I could give 1000 stars I would. Finally, I can breathe! Thank you to the seller and to whomever created this. Money well spent.

Disgustingly effective. Works very well placed near the back door of our property however seems to attract the larger bluebottle type flies. He haven’t had any of them in the house since placing it there however some of the smaller ones (larger than fruit fly but smaller than bluebottle) don’t seem to attracted to it. It’s also caught the odd wasp too! Would recommend for the summer when you have the door open and want to reduce pests. Picture below is after 7 days of use.

If you're plagued by flies around your garden, patio, or outdoor dining area, look no further – the Zero In Outdoor Fly Trap is an absolute game-changer! This twin pack is incredibly effective and has made our outdoor spaces so much more enjoyable.Setting them up is an absolute breeze. They come ready-baited, so there's no messy mixing or complicated instructions. You just add water, hang them up, and they start working immediately. Within hours, we noticed a significant reduction in the number of flies buzzing around. It's almost unbelievable how many flies these traps manage to attract and contain.The fact that they are non-toxic is a huge peace of mind, especially with pets and children around. They rely on attracting the flies rather than harmful chemicals, which is fantastic. Each trap lasts for a good 2-3 weeks, providing consistent protection without constant monitoring.While the traps themselves become full of flies (which is the point!), they effectively contain them, and the design makes disposal relatively easy once full.Seriously, if flies are ruining your outdoor experience, invest in these. They are incredibly effective, easy to use, and genuinely deliver on their promise. A full 5 stars – I wouldn't be without them now!
