In order to have a sucessful treatment of drain flies you must first identify the source. You can help identify the source by using the glueboards in the Drain Fly Kit. Place the glueboards in suspected hot spots and monitor activity. Most of the time the source will be in drains where drain flies feed and reproduce. We would recommend treating all the drains in the basement (sinks, bathtubs, floor drains) with a drain gel such as the Invade Bio Drain that is included in the kit. You need to run hot water for aproximately 30 seconds in the drain prior to applying the drain gel to soften the organic build up. Turn the water off, then apply 4 oz of the drain gel to the drain paying close attention to he sides of the drain. Do not pour it directly down the center, coat the sides as best as possible. Once you have done that you would want to fold the glueboards and place them on top of the drain by folding them in half like a tent. You would repeat this for 7 nights. Use the On Time Aerosol to lightly mist around infested sinks to kill nuisance flies during treatment.
