This pesky little fly can show up any time of the year and by its name it appears around drains. Many restaurants begin to see them in the fall. Drain flies are attracted to liquers and mixed drink flavor containers in bar areas.
To eliminate drain flies from your home or business you will need Enviropro DF-5000, Vector Bio-5 Multi-Purpose Drain Cleaner or Drain Gel Bacteria. These products, when used according to directions, will eliminate the breeding and harborage areas where drain flies live, primarily the "J Trap" or as some call the elbowed drainpipe the "Goose Neck". This is where drain flies live and breed.
Enviropro DF-5000, Vector Bio-5 Multi-Purpose Drain Cleaner and Drain Gel Bacteria break down and destroy the bacteria that drain flies require to survive. Usually within a week you will notice there are no more drain flies. All of these products eliminate the bacteria but don’t actually kill the drain flies.
