What is the best combine use when using Bio Drain and Gentrol to control drain flies and phorid flies?

If you put the biodrain in, does it take away the effectivness of the gentrol?

Answer:

Gentrol IGR should be mixed with water and can be used inside the downspout and catch basin area of the drain. This application will be completed before you use the Invade Bio Drain. You will repeat applications every 2-4 weeks.  The Invade Bio Drain should be used by itself. You will use this to coat the drain and kill the microbes inside the drain.
