[step] One of the most effective homemade fly traps is made using a simple plastic water bottle. [substeps] Unscrew and remove the cap, then use scissors to pierce the plastic and cut off the top quarter of the bottle.

Ending1: Fill the bottom part of the bottle with a quarter cup (60 ml) of sugar, a quarter cup (60 ml) of water, and a couple of drops of blue food colouring. The blue colour helps to attract flies, but most colours or no colours will attract flies as long as it isn't yellow. Ending2: Leave the cap on but spread it open so it is easy to grab. Take the jar and shake it until the contents are covered. Ending3: Insert your fly into the empty water bottle. Pull the cap straight out of the bottle using the lid. Ending4: Leave a small hole in the neck of the bottle. Put one end of the bottle in the hole.
