Are Traps Effective When Dealing with Yellow Flies in Florida? 

Yellow flies are some of the most difficult Florida flies to manage. Traps are somewhat effective, as are emptying standing pools of water around your home (this will also help cut down on mosquito and sand flea populations). It's important to prevent ways that yellow flies can get into your home. Although female yellow flies consume blood, male yellow flies prefer pollen and nectar - meaning sugary drinks or spills will attract the overall yellow fly population.
