When summer comes around, so do the fruit flies. These little buggers are attracted to the sweet, sweet smell of beer...and who can blame them? But once they smell the sticky syrup that condenses in the mouth of your faucet, they colonize and take over, laying eggs and making your kegerator or draft setup a nightmare! Keep those fruit flies out of your tap with Beer Tap Caps! These little rubber caps, though inconspicuous, can save you from summertime infestations of biblical proportions. Keep these on your faucets when not in use, and you'll drastically reduce fruit fly populations in and around your draft system!
