What is the best combination of products to use for Phorid Flies?

I was thinking DF 5000 Drain Fly Gel and/or InVade Bio Drain Gel as well as Gentrol Aerosol. What is the difference between the DF & InVade?


If the Phorid flies are breeding in drains that have a buildup of organic matter and DF5000 is used it can help get rid of those pests. Adding Gentrol to the treatment program can definitely help break the cycle of infestation. DF5000 and Invade are very similar and will do the same thing for you, they are just made by different manufacturers. You can also use insect glue traps to capture the breeding adults which will help you monitor the infestation and help eliminate them from the breeding pool.
