Items needed:
1 cup of water
1/4 cup of brown sugar
1 gram of yeast
1 2-liter bottle

1. Cut the plastic bottle in half.
2. Mix brown sugar with hot water. Let cool. When cold, pour in the bottom half of the bottle.
3. Add the yeast. No need to mix. It creates carbon dioxide, which attracts mosquitoes.
4. Place the funnel part, upside down, into the other half of the bottle, taping them together if desired.
5. Wrap the bottle with something black, leaving the top uncovered, and place it outside in an area away from your normal gathering area. (Mosquitoes are also drawn to the color black.)

Change the solution every 2 weeks for continuous control.

If you don’t like making things or can’t get this thing to work correctly for some strange reason, then you can always try one of these that are guaranteed to work.

DIY Mosquito Trap that WORKS!


  1. It works. It TRUELY does. There are many others but THIS is the one.

  2. It worked on flies and only got 1 mosquito.

  3. Kathleen says:

    After 2 weeks, the trap caught one mosquito and about 100 fruit flies. Now, after rains, the mosquitoes are out if full force. Sucker that I am, I’m trying the trap one more time.

  4. Did not think it was working at first but behold, there were dead skitters floating…alrighty then!!

  5. mosquito man says:

    I do not know how well this works, but for people that have tried this for only a day or two, the yeast takes time to ferment. It is the fermentation of the yeast that releases the CO2. Temperature and humidity will effect the time and amount.

  6. Just did this yesterday. The mosquito population is really bad this year. Unfortunately, after being out for 24 hours, just caught 1 fly. This doesn’t work at all. Although mosquitoes may be attracted to the CO2, they do not fly into the contraption.

  7. I can also attest to the fact that this DOES NOT work. Did the traps exactly per the instructions above, had them out for a week and hasn’t caught a single mosquito. There are few bugs in there, but no Mosquitos. Don’t waste your time folks.
