Modern technology has brought us many benefits, including mosquito traps that cost a lot of money, but sometimes we overlook simple solutions to difficult challenges such as mosquito control. When it comes to controlling pests, research tends to focus on chemicals or concepts that can be patented. Unless someone can make a profit from an idea, the public may never become aware of it.

HOMEMADE MOSQUITO TRAP:

Items needed:

200 ml water
50 grams of brown sugar
1 gram of yeast
2-liter plastic bottle

Or US conversion:
1 cup of water
1/4 cup of brown sugar

HOW:
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.

Your idea for mosquito trap seems interesting and useful. I will definitely try this. You can also call Mosquito Control Westchester NY, which I used recently for mosquito control in my shop.
