We do not recommend the above pesticides to control drain flies. See our website for photos and control information. You need to find a breeding site or sites. Make sure you have no leaks. If you find the issue are drains, clean the traps and drains mechanically or an over the counter drain cleaner with enzymes followed by hot water. You can find these enzyme drain cleaners in big box or home improvement stores. http://extension.umd.edu/hgic/drain-flies
