Don't let those darn Fruit Flies take over you bar!  Give them an inch and they will take a mile!  There is a lot you can do to prevent them from flourishing.  Here's some things you can do:

• No standing water, anywhere!
• All drains including floor - sanitizer
• Plug beer taps
• Clean and plug beer drip tray
• Rinse and store empty beer bottles
• Cover liquor bottles
• Wipe down bottles
• Clean soda gun
• Bar mats must be clean
• Keep garnishes covered and cold.  Wash fruit before cutting.
• Don’t be surprised if fruit flies feed on the residue remaining on damp mops, moist cleaning rags and sponges, or near buckets of wastewater.
• Bottom of trash cans?

• Last resort - traps
