I have a container garden on my front porch that is infested with fungus gnats. My "garden" is in half a wine barrel that was bought at lowes and washed out. I used bark, cheap potting soil, peat moss and perlite for my potting mixture. My garden is only a couple months old, and the blubs I planted in there just started popping up about 3 weeks ago. About the same time the gnat problem started. Now my plants are starting to die!!

I've heard a lot about Gnatrol solving the problem, but where can I get it? I've searched at Lowes and Home Depot, etc., and have had no luck.

Any help please! I want to save my garden!
