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 - For best results, introduce immediately upon receipt. If storage is necessary, store at 36-45°F for no more than 30 days (refrigerate). Store in a dark place. Do not freeze. Once activated, release within 1-6 hours. - Rate: up to 5,000 square feet of growing space - The ice pack is expected to be melted and warm upon arrival. If the nematodes are no longer viable, they will have a fishy or rotten smell. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08P3WMCLV | | Best Sellers Rank | #150,986 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #364 in Beneficial Pest Control Insects | | Brand | NaturesGoodGuys | | Brand Name | NaturesGoodGuys | | Customer Reviews | 4.1 out of 5 stars 202 Reviews | | Manufacturer | Natures Good Guys | | Target Species | Insects | | UPC | 657994300083 | | Unit Count | 1 Count | ## Product Details - **Brand:** NaturesGoodGuys - **Target Species:** Rodents - **UPC:** 657994300083 - **Unit Count:** 1 Count ## Images ![Natures Good Guys - Beneficial Nematodes Steinernema Feltiae - SF (50 Million) - Image 1](https://m.media-amazon.com/images/I/71fszYe-E+L.jpg) ![Natures Good Guys - Beneficial Nematodes Steinernema Feltiae - SF (50 Million) - Image 2](https://m.media-amazon.com/images/I/91+omto737L.jpg) ![Natures Good Guys - Beneficial Nematodes Steinernema Feltiae - SF (50 Million) - Image 3](https://m.media-amazon.com/images/I/81rQpO7pc+L.jpg) ![Natures Good Guys - Beneficial Nematodes Steinernema Feltiae - SF (50 Million) - Image 4](https://m.media-amazon.com/images/I/51qo2yKhkOL.jpg) ![Natures Good Guys - Beneficial Nematodes Steinernema Feltiae - SF (50 Million) - Image 5](https://m.media-amazon.com/images/I/61ZvWfSOlDL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ GOODBYE FUNGUS GNATS *by K***M on February 12, 2024* 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!!!
