DIY mosquito trap. Take a 2 L bottle, cut in half. Dissolve (boil) 50 g sugar with 2-3 dl water, cool it down. Add 1 g yeast, put it in the bottom. Turn the top of the bottle upside down (tape), put black paper around the bottle. The carbon dioxide produced and the black color should attract the mosquitoes, which will end up inside the bottel. I have to try this!
