Cut just below the point where the neck of the bottle straightens out onto the body of the bottle to create a cylinder and a funnel. Fit the funnel snugly into the cylinder. Fill about 1/3 of the cylinder with a mixture of 1 tablespoon of dry yeast, 1/3 cup of honey (or sugar) and warm water. Wrap a piece of black paper around this to make a nice warm comfy place for mosquitoes to hide. The trap works by creating carbon dioxide with the honey (or sugar) and yeast mixture.
