Pins I’ve Tried: Mosquito Trap FAIL

Pins I've Tried: Easy Cinnamon Bun Waffles

We live in south Florida, a place known for it’s bugs. We have a ton of mosquitos, and we have tried many ways to get rid of them. We have a bug zapper, which does work, but not nearly enough. We would need about ten of them to really make the outside a comfortable place to hang out during the summer months. At about $100 a pop, plus having outlets put in around the house to run them, well, that would get expensive very quickly. We’ve tried yard sprays – and they work, for about 10 minutes, when the neighbor’s mosquitos decide to fly over. I’ve considered buying a bat house, but I’m not quite there yet.

So, when I saw this pin on Pinterest, I figured I would give it a try.

DIY Mosquito trap

Unfortunately, many of these pins were linked to spam sites, so I just Googled it and came up with this website.…

Necessary items:

1 empty two liter bottle

1 cup boiling hot water

1 cup of sugar

2 cups cold water

1 tablespoon active yeast

black (or in my case, dark colored) paper



I cut the top off the bottle, and inverted it back into the base. Then I mixed the boiling water with the sugar, stirred until it was all dissolved. Then added the cool water. It said to make sure the water was 90 degrees, but since I didn’t have a candy thermometer, I just made sure it was lukewarm. Then I added the yeast, mixed slightly. I poured the mixture into two bottles that I had set up (the recipe makes too much for just one bottle). Then I taped the lid to the top, and taped a piece of dark scrapbook paper to the outside to make it all mosquito friendly. They love a dark, humid place.

I put the bottles behind some bushes in my yard and waited a few days. Each day, I would run out to check them. And each day, I was disappointed that they weren’t working. They did seem to attract this guy though…

Isn’t he just a beauty? Ick!

He stuck around for two days. Didn’t move. Ewww… Where we live, we have tons of these  guys. One lick of this bufo toad can possibly kill my dogs. Unfortunately, I haven’t found anything to get rid of them, either.

Okay, back to the mosquito trap… All that’s been caught so far are a few gnats and some grass clippings.

This is one of the bottles this morning.

I’d say this was a FAIL!

For the sake of science, I’m going to try this one more time. But, I have to say, I’m pretty disappointed in the dismal outcome.

Have you tried any new pins lately?? Were they a success? Or a big-time FAIL?


Come back soon!

    I missed the weight loss part of this article (confused). However my husband did try the mosquito trap twice and it didn’t work, so bummed as we get a lot of mosquitoes where we live.

    Hi! Your mosquito trap didn’t work because you must use BROWN sugar…1 cup of boiling water mixed with 1/4 cup of brown sugar stir til sugar desolves then when cool add 1 gram of yeast and do not stir…1 gram is a little under 1/4 of a tsp…the rest of the directions you followed were correct! Give this a try!:)

    I had the same result, no mosquitos were trapped. I used white sugar too, so maybe I will try brown sugar. Let me know if you had any results!

    Hi! The problem was incorrect temperature of the water. It shouldnt be boiling hot… it should be 36-40 c depending on the yeast; 37c many says is ideal. But if it’s in a warm country you can use water in room temperature, make the “recipe” and just leave it in the sun. Ah, and i used baking yeast, worked pretty good:D sorry for my bad english :3

    Well, we just tried it…with brown sugar…but didn’t really measure anything (rarely do) and water was a mild warm…guess we’ll see!

    I’ve made 3 of these and none of them worked, besides catching a bunch of gnats (which is still good). Water does not need to be boiling, only hot enough to melt the sugar. I havent read anywhere yet that this has actually worked.

    Tried it here in Australia – with brown sugar – but it didn’t work on mozzies. Got lots of those little flies (I think you call them gnats). I’d like to try the fan trick seen on various mozzie-zapping boards but because I live in the city, where houses are close together, I think the noise would drive my neighbours mad; not to mention the cost/environment minuses of running a fan 24/7.
