DIY Mosquito Trap.

By Alex in Everything Else on May 31, 2006 at 9:33 pm

DIY Happy has this guide on how to make your own mosquito trap using a 2-liter soda bottle.

1. Cut the top of the bottle as shown

2. Put 200ml hot water in the bottle, stir with 50gram brown sugar. Put the sugar water in cold water to cool it down til 40C (temperature)….

3. After cooling down, put the sugar water in the bottle then add the yeast. No need to mix the yeast with the sugar water. When yeast ferments, it creates carbon dioxide.

4. When you cut the bottle, dont throw the top part away because that’d be needed for step 4 – you see they put the top upside down to fit into the bottle….

5. Put black paper around the bottle since mosquitos like dark places and carbon dioxide. This mosquito trap will then start working. Mosquitos fly around the corner, so the best place to place the trap is at some dark corner.

    “Mosquitos fly around the corner, so the best place to place the trap is at some dark corner”

    Let’s face it — that’s just stupid. Mosquitos don’t care whether they’re flying around a corner or not. Anyway, I made this and caught a fly and two ants. Mosquitos ignored it — just like people should.

    Give some credit to the designers, this is pathetic…This article is stolen from a Chinese school project. Only thing is different is the occasional word and “mosquitos like dark corners”, which is complete bullshit.

    Also, I made this and it didn’t work. At all.
    There is about 50+ mosquitos buzzing around my porch, with the trap right in the middle. They are all ignoring it.

    Mosquitos at my house are all found in the darker corners where two walls meet, so at least in Florida the mosquitos do like to hide around the corners. After Tropical Storm Faye we now have millions of the darn things hiding in the corners. I’m horrified and will be trying lots of different things….this homemade trap will be one of them. I hope it works.

    The best soulution I have found for mosquitos is a product called Skeet-r-done. It is the best thing I have ever tried. I have been using this for over a year now and as long as I use it I have never gotten a mosquito bite. Their web site is

    If you have a mosquito issue you must give it a try!

    mosquitoes hide in the shade during the day when its hot. They are more active early in the morning and evenings when its cooler. They usually go on “searching” flights in the evening and night for blood sources. That is where dark shade comes into play. To the person with the skeet-r-done product that probably works for the company: It won’t work. Use a product with DEET it is the most effective and it won’t hurt you. The other products that have “natural” items like citronella in them aren’t effective more than 10-15 mins.

    I really thought when I make this mosquito trap there will be true mosquitoes that trap, why is it that there are more ants that attract compared to the mosquitoes.

    But not that’s worst there was some wrigglers that in there and it could be probably that the mosquitoes lay eggs there so the population of mosquitoes will be lessen…

    Actually, this is quite effective if done right. The mixture of yeast and sugar produces CO2 that attracts mosquitoes. Not an original idea though..
