Big Time Exterminator - Clearance Reviews

My indoor garden suffers from root aphids. It's a problem many of us have. This product was something I read about online. Sounded good, found it here on one of my favorite sites, so I bought it. Thus far, I've tried using this product 3 times, explicitly following the directions, and have not seen the infestation diminish. I'm actually pretty surprised as I've seen other products with the same ingredients work well. Maybe I'm using this product incorrectly? Maybe this is a bad batch? I dunno. I'll continue buying from Build-A-Soil no matter what. These guys are great!
