They really work, got rid of my fungus knat problem

Works so well! We’ve had a problem with tiny plant flies and this has done a great job at keeping them at bay! The only problem we had is that the little guys climb up from the dirt, so we had to change them more often than we’d like at first. But now it’s much better!

These work great on my orchid

Non capisco come possa funzionare per altre persone... non è altro che appiccicoso, non ha nulla per attirare i moscerini (che continuano a morire altrove)

If you're reading a bunch of reviews while searching for yellow sticky cards, stop now and buy these. The number one complaint I saw on other products of the same type is that the paper was very difficult to remove from the sticky portion. On this product, however, the paper was incredibly easy to remove, even when I tore it in half while removing. Just bend the sticky card at the point that connects the shape to the part that goes into the soil, and you'll see a tab that's not stuck to the card. Easy peasy!I had no problem pushing them into the soil in my planters (the second biggest complaint I saw). Of course, if you try to push it into the center of your pot, you're likely to encounter the roots of your plant. I found it worked best to slide it along the edge of the pot when possible. The items were firm enough to make this an easy task.The biggest question: Do they work? These photos were taken only 30 minutes after I put them in my pots, so I'd say they definitely work. (Yes, I have a gnat problem.) While this isn't the only thing that will likely solve the my gnat problem, it's an important part. Catching these adult gnats will decrease the number of eggs that can be laid in the potting soil. I also soaked a mosquito dunk in water and am using that to water my plants. (Mosquito dunks are made from BTi (Bacillus Thuringiensis subspecies israelensis, which is organic and will kill the larvae in the soil.) Lastly, I'll be adding a 1/4" layer of sand to the top of my pots tomorrow, which is supposed to prevent the adults from accessing the potting soil to lay eggs. I'm confident that this 3 pronged approach, including this specific product, will solve my gnat problem over time.Besides being effective and easy to use, I appreciate that the sticky cards come in a nice box. While these are kind of gross to look at after awhile, if we're honest, I appreciate that the box holding the rest of my sticky cards will look just fine on an open shelf. It's just a nice touch.One last tip: It got dark shortly after I took this picture, and this room light was turned off while I was in the next room with a lamp on. A few gnats were attracted to the lamp I was sitting under, driving me nuts, and it didn't look like a whole lot more gnats were getting stuck on the cards in the hour that passed. I turned the light on in the room with my plants again, and they started getting stuck again and not bugging me by the lamp. I don't think it will be necessary to keep the light on all night. I just think that for a few days it might make sense to keep that room light on while I have a lamp on in the next room to avoid drawing the gnats away from my plants. After all, if they can't see the pretty yellow color, they won't be lured to the sticky surface. It's a small price to pay to get rid of the little buggers.

I tried the apple cider vinegar traps but wasn't really catching very many fungas gnats.Set these traps up and within 15 minutes I thought I'd caught loads, been 24 hours now and I'm really pleased with how these have worked out.Really easy to use and really effective for the price.

One Year Update: Yes! I definitely have fewer, to no gnats this year thanks to using these last year.Original review:A co-worker suggested I purchase these to get rid of the tiny gnats that come from house plant's soil.These work great with a couple notes — My pics show that some of the gnat traps have fewer bugs than others. This is normal because some soils propagate more gnats than other soils (due to some nurseries not using sterilized soil). Also, I read that the gnats have a specific lifecycle. For many months you may catch very few bugs. When the larvae mature, the gnats fly out of the soil and, wham, you catch hundreds. I put these in my pots in Spring, and there were only a few flies trapped. In my state, Colorado, the gnats flew in late Summer, then hundreds were trapped.Positive:• Remain very sticky for months.• Cute design does not look horrible in pots.• Easy to use. The traps caught a few fruit flies too, but no houseflies.• No odor, no mess. Just throw out buggy traps and replace with fresh trap.• Non-toxic to humans and pets. The bright yellow color is the attractant.Negative:• The traps are very sticky, they will stick to plants, fingers & anything that comes in contact with them. They may be removed but will definitely tear your plant's leaves. I had one stick to a couple of my fingers. It did not hurt to remove it, but the trap left some sticky residue on my skin.Finally, I use these indoors only. We don't have mosquitos here; but we have butterflies & dragonflies that we don't want trapped. So, I have no idea how effective these are for outdoor insects.I'm also curious if I'll have fewer gnats overall next year. I'll try to update then.

UPDATED REVIEW: these traps do work!! You can see from my old review that in the first 9 days there was only one gnat stuck to one trap (out of 3 traps). However, just a few days after that, there were tons of gnats stuck to these traps! I have no clue what changed and why they all suddenly started working... but they did! There are still a few pesky gnats flying around but not nearly as many as there would have been. I even put 3 more up (two more in my room and one nearly the kitchen fruit bowl), and they have all caught some. I will add more pics of a couple of traps for comparison. Bottom line: I do recommend these. They worked for me for both plant gnat issues and fruit flies, but it took a full 2 weeks for me to see them work. This also seems to be the cheapest pack/best deal for gnat traps! By the way, the first trap I saw with the lots of gnats was attached to a cup with apple cider vinegar, so that may have helped.Old review: I don’t like to write negative reviews of products, but the company asks for your honest review, and honestly... these have not worked for me at all. I have had these in my room for over a week (9 days), and there are still gnats everywhere. I have put 3 in my bedroom (2 in different plants, 1 on a cup of apple cider vinegar near a plant), and one in hanging in my bathroom. I’m 95% sure that my gnats come from the various potted plants in my room, but ironically the only trap that has caught a gnat is the one hanging in my bathroom where I do not have any plants. In the pic you will see two gnats on one side, and one gnat on the other; the two trapped gnats were ones I caught by hand to test how sticky it was (it is very sticky on both sides). As I was taking pics for this review, noticed the other gnat on the other side- so these traps have caught 1 gnat in nine days. I will leave these traps up in hopes that maybe they will ... start working? I’m not sure why these do not work for me, but I doubt that other more expensive brands have products that are any better. This product is easy to use, and the adhesive is very sticky. I am giving it 2 stars because these traps (I put up 4) have only caught 1 gnat, but at least they have caught one! I will update if they catch any more.
