The Drain Fly Kit with DF 5000 drain will treat up to 2 infested drains and includes Clean Air Purge III metered aerosol to control nuisance flies during the treatment process, and three Catchmaster glue boards to monitor infested drains.

If you have drain flies in a master bathroom with 4 drains (ie; 2 sinks, tub, and shower), you would need 2 drain fly kits. One bottle of DF 5000 Drain Gel does one drain for one week.

Clean Air Purge III metered aerosol to control nuisance flies during the treatment process, and three Catchmaster glue boards to monitor infested drains. Clean Air Purge will shoot out in quick misting spurts that will allow you to spot treat around sinks and drains and in open areas.
Drain Fly Kit Instructions:1. First, you should cover infested drains with the included Catchmaster glue board traps. You do this by folding the boards in half like a tent, and then peeling off the plastic film on the glue. Place the glue board over each drain at night that you want to monitor. The board should sit slightly up off the drain (as shown in the image below), allowing air to move into and out of the drain. This will allow you to (1) determine which drains are infested by drain flies so you can focus your treatment in the right areas, and (2) monitor and control infested drains during treatment by catching adult flies that exit the drain. If you are treating a bathroom, you should place one glue board over the sink and one over the bathtub drain. Tip: After each night, circle caught flies with a marker so that you can see how many were caught each day.

2. Pour 4 oz. of DF 5000 drain gel down each infested drain every night for at least 7 nights.
DO NOT rinse the drain with water right after applying the DF5000 -- you should let the sink sit all night without being used. Cover the drain with a glue board (see step 1) during the night to catch any escaping flies.
3. Use the Clean Air Purge III to lightly mist around infested sinks to kill nuisance flies during treatment.
