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: THIS STUFF WORKS - Man...I had an infestation of fungus gnats and bought some of this...mixed it with water and used it in my 5 gallon pots and not only did they bounce after 2 days, but they never came back EVER. It was like graveyard for insects in that soil. I kept imagining the horror of a gnat larva as he watched something bore into his insides....stayed like that until I harvested. I am here writing this review right now because I came back for another order, dem damn pests are at it again, same culprit. Time to release dem dogs. ## Features - Beneficial Nematodes Species: SF (Steinernema feltiae) - Great enemies to fungus gnats, root nematodes and many more - Safe to use around humans, plants, and pets - For best results, introduce immediately upon receipt.
