Will Temprid FX Insecticide work on adult drain flies hovering around windows and baseboards?

I am treating the breeding sites with Gentrol foam. I am starting another round of drain treatments. I have adult flies on several windows and by my front door. They seem to be going under the foundation of my house and escaping by the windows.


Temprid FX Insecticide could kill those adult drain flies that contact a treated area long enough to receive a lethal dose.  Please refer to our How to get rid of Drain Flies guide for fthe most effective treatment.
