Not all pest control issues require pesticides. Many times sanitation is all that is needed. Places like this trough style drain in the floor of a bathroom shower area need to be cleaned out on a regular basis. All it takes is a little clog or backup and the drain will fill with sludge and then the flies will show up. A few will turn into many in just a short time. In a situation like this the drain should be unclogged then use cleaning products to flush the trough out. If it's really bad a shop-vac may help in clean out. Once this is cleaned out the drain fly/drain moth issue should clear up in just a few days. Drain flies have a very short life span. Adult drain flies only live for about 2 weeks.
