Fighting Dengue: Mosquito trap

Fighting Dengue: Mosquito trap

It’s just a mix of water, brown sugar and yeast.

You need:

*A 2 liter plastic bottle.
*50 g of coarse sugar (like rock sugar etc., not the fine granulated stuff.)
*1 g yeast powder/ granules
*A thermometer
*A measuring cup

The steps

1. Cut a plastic bottle in half, keep both parts. Can be CocaCola/Pepsi. No matterlah!

2. Take the lower portion of the bottle. Dissolve naturally the brown sugar in hot water. Let it cool down to 40 degC. You don't have to mix - it will react gradually with the sugar to produce CO2, the magic mozzie attractant.

3. Add the yeast. Carbon dioxide will form (This will attract the mosquitos). Fit the top part of the bottle snugly into the bottom part. Make it a tight fit so that the CO2 that's produced will only be coming out of the hole in the middle.

4. Cover the bottle with a dark wrap and place the top portion upside down like a funnel. Place it in a corner in your house.

5. In two weeks you will be surprised by the number of mosquitos killed. Replace sugar water and yeast every two weeks.

This method was devised by Hsu Jia-chang's class at Yong-An elementary school, Taipei, Taiwan, with the help of their teacher, Hsu Jia-chang. The school website at here.
