Will Microcare and Gentrol Aerosol IGR work for drain flies?

I've just started using Microcare with Gentrol Aerosol IGR for a really bad drain fly infestation. Is this a good combination and how long until I see results?


Microcare is a good product to knock down the adult flies that are flying around the kitchen, and Gentrol Aerosol IGR is a good product to help with future drain flies from hatching.  However, drain flies breed in organic "gunk" that is down the drain.  You need something to put down the drain that will eat this gunk away or it will continue to be a problem.  This is where drain gel comes in.  The Microcare and Gentrol will put a band aid on the problem but you will continue to battle them.  We have a Drain Fly Kit just for your situation.  Drain gel poured down the drain every night for about a week will eat away at the "gunk" and eliminate the source of the problem.  So this does not happen again, you should use drain gel once a month for maintenance on your drains so the "gunk" does not build up again.
