Rockwell Labs - 729991 - Invade Bio Foam Concentrate - 1 Pint, 16_Ounce, Orange

Exelente product.I was having problem whith drain flies.I pour into my bathroom drain and they gone, no more flies around the house

Someone recommended their product To help with little black flies in our house. I was scrubbing and scrubbing the drains but it wasn’t working. This product took care of it in two uses. Now we use once a month.

This stuff just rocks. I use this for my residential and commercial clients and they are very happy with the results.

I thought that it would kill the drain flies in one of two applications. It took three plus the use of a fly swatter. The flies were smaller that a flyswatter. Used that and a fly trap with the Bio Foam to eliminate the drain flyies. Will use it again.

Haven't used it yet. But, it seems to be what's needed.

In combination with bio foam I raise hell on drain flies

I used it in a foam sprayer every day and didn't see a change in flies. Even after doubling the strength of the mixture it still didn't work.

Amazing product, quick delivery, arrived sooner than expected date. Product was properly packed and secured. Definitely up to standard!
