How do I get rid of drain flies in the kitchen?

I am having a big problem with drain flies in my home kitchen. My problem is that I cannot remove the cross bars in sink drain, so I will not be able to apply the gel to the sides of drain. Before I purchase, I thought I would ask your help. These things are really annoying, and I would like to rid them, prior to the holidays. Thanks!


Most people cannot remove the cross bars on the drain and that is ok.  The Invade Bio Drain and our other gels have a spout on the top and you can squeeze the bottle and "shoot" the product out the spout onto the sides of the drain.  Also, if you treat along the outside perimeter of the drain it should run down the sides where it needs to go.  You may want to consider our Drain Fly Kit which has a very high success rate.
