Mosquito trap (Dengue prevention)

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

1. Cut a plastic bottle in half, keep both parts. Can be Coca Cola / Pepsi bottle.

2.   Take the lower portion of the bottle. Dissolve the brown sugar in hot water. Let it cool down to ~70 deg F.

3.  Add the yeast. Carbon dioxide will form (This will attract the mosquitoes)

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 2 weeks you will be surprised by the number of mosquitoes killed. Check this link and this other link.
