Review: GOODBYE FUNGUS GNATS - I was skeptical that something as "easy" as adding nematodes to my plant chores ever so often would do anything to my fungus gnat invasion but boy was I WRONG!!! The package we ordered more than took care of our over 40 plants! We even had more than we needed and sadly had to throw away the package due to the lifespan of the 'todes. The instructions were clear and simple to follow and these eliminated the fungus gnat eggs within a few days. To finish them off we used a few yellow sticky traps to catch the adults and voila they were gone and we haven't seen a single gnat now in almost three months! If you have fungus gnats or any other similar pests GET THESE NOW!!! You will not regret it!
Review: Great product - I tried everything to get rid of the fungus gnats…… everything ! I baked the dirt, used more yellow sticky traps than you could imagine, used Mosquito bits….. these little pests would not go away. Then, I hit them with these little worms, left for a 2 week vacation…. It’s been 6 months and I still have not seem one. I was infested… at least 12 plants in different rooms.
