Bottle Cap Fruit Fly Trap (4-Pack)

I was skeptical at first, because for 2 reasons: funnel opening is big, and seemingly simple design compare to other traps. The first day, I placed it o top the basket of apples, and none entered. Now I placed all the pples in a closed bucket with lid, and put the trap on top. Boom! deprived of other "easy" food source, they entered the trap em mass! The funnel,large as it is, effectively prevents the flies from escaping. I watched for many minutes, and saw not one fly managed to crawled back out of the funnel. Contrary to another reviewer, I doubt an open bottle would block the flies to flying out. I attaced a picture of the trap some flies inside.UPDATED 6/5/2016:After left it sits for a few days, and the trap was full. I added a new picture of the device with crawling and many dead flies in the bait. For bait I used apple cider vinegar and ripe banana. It seemed to be a irresistible food for flies.

I really had no doubt that this would work - it seemed to make all the sense in the world - but until you actually see the results, you will always wonder.Well, wonder no more: This thing works magically - and it really makes you realize just how many fruit flies have been buzzing around before, until you count the dead ones in the jar, just within the first couple of days after putting it out.I see no less than at least a dozen (or more) just in the first two days, and I figured that there would be three or four, at most.They recommend to use whatever the flies have been attracted to as the bait, (which in my case was bananas) but I didn't want to put bananas in the jar, because they go bad and stink up the place pretty quick.But they also mentioned apple cider vinegar, which I used - with a squirt of honey - and it works like a charm.So easy - and the fruit flies really are an annoyance, and something you're glad to have done away with.

I have waited about 2 weeks of use before I left a review of this product and let me start by saying that it works. It takes a few experiments to find out what works best for attracting these little pests. I started off with apple cider vinegar in one bottle and wine in another.... if you are willing to spare some of your wine that is ;)..... Also do note that when I first used this product I was already the last half of a bottle of wine in and very upset that the product was not going into the wine bottle like I wanted it to... make sure you use a water bottle and all will be great in life! I thought I would be able to have an excuse to drink wine because of needing the bottle for usage... made me feel better about myself! Any who, the wine worked great at attracting them but I think that the apple cider vinegar was the best choice in my opinion. I read in a few other reviews that some people put food in theres... well I didn't due to not wanting rotting food smell in the house. I filled the bottles halfway with apple cider vinegar and nothing else, the 2 with wine I did like 1/4 wine to 3/4 water and also filled it halfway... I didn't want to waste the wine and was a little selfish! I placed all four around the kitchen area, 1 on the kitchen table, another on the kitchen counter next to the stove, another next to the kitchen sink, and I have a pet rabbit that tends to attract them in his waste pile so I put one next to his cage. The first night was not very successful but I think that also had to do with the fact that I made a super yummy spaghetti that night and they were too busy trying to get to that. I did manage to capture a couple that night in the bottle that I placed on the kitchen table and three or four in the bottle next to the rabbit cage... those ones just had apple cider vinegar in them. I didn't really notice too much of a difference until day 3, that's when I saw less activity in the kitchen and checked the bottles to find at least 2 dozen dead fruit flies in the kitchen bottles and I don't even want to say how many were in the one that was next to the bunny... not good! I refreshed that bottle and to be honest I just shook/swirled the others around until all the bugs were gone from the surface... I am not proud of myself for being lazy but at least I am honest lol.If you are looking for a great and natural way to get rid of those pesty fruit fly's that just don't seem to want to die from fly traps, try this... I wish I had found this product sooner. It really works.

The other solutions we tried never seemed to get the job done completely and required more attention. With this one, we did not experience any more fruit fly "outbreaks" or witness any escapees. Maintenance is super easy. Used bits of banana peel (or fruit of some kind) and apple cider vinegar for bait. May need a little experimentation with placement and bait on your part. A good recommendation would be to try shorter bottles.

Upon examination these are 3-d printed, which I did not want for a fly trap as mold can grow in the layers of the print. If I wanted a 3 -d printed one I would have done it myself, free models can be found online for this exact thing. I was hoping for a solid plastic so I wouldn't have to worry about the potential for mold, with the right bait these are functional, it's just not what I wanted material-wise. I might make a base for the bottom of the funnel with a few small holes to ensure no escape, I have plenty of pla lying around and prints glue easily. A clear coat on the parts that do not thread onto the bottle will fix the potential for mold issue for the most part, but it should have been addressed in the making of these and should not fall to the consumer to have to do.

These worked Great!! They arrived in the afternoon. I mixed up 2 drops dish soap, 1/8 tsp sugar, and 2 Tablespoons Apple Cider Vinegar in an empty water bottle. Within 2 hours I had already captured and killed a few Fruit Flys in each one. By the next day the Fruit Fly issue was gone. I swap them out every week and now do not have a problem with the Fruit Flys.
