Some friend of yours who just moved here from New York? Spotted on Bartlett.

Pennies V. Fruit Flies

Pennies V. Fruit Flies
Facing an invasion of fruit flies at The Secret Alley, Noel decides to employ a less-than-obvious method of getting rid of them: hanging a plastic bag with water and pennies in it over the counter. The idea being (I think) that the light reflecting out of the bag will confuse the little buggers, causing them to scatter.

Just in case this doesn’t happen to work, anyone have any other helpful ideas? The least obvious the better.
