How to catch flies
Make a trap from a plastic bottle.
One of the most effective homemade fly traps is made using a simple plastic water bottle.
Unscrew and remove the cap, then use scissors to pierce the plastic and cut off the top quarter of the bottle.

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.

How to clean household surfaces efficiently
Don't work against yourself by re-soiling clean areas.
Work from top to bottom, and from back to front (i.e., toward an exit or opening.
Remove loose matter in its easy-to-remove loose state.

Vacuum it or wipe it off with a dry towel. Don't start by making it wet and sticky.
