NaturesGoodGuys Sf Nematodes ( Steinernema feltiae ) are beneficial, soil-dwelling microscopic organisms that seek out and control soil pests such as fungus gnats, root aphids, shore flies, and other root-feeding larvae. They actively hunt their hosts and provide natural, chemical-free pest control in potted plants, greenhouse, and garden soils. Target Pests: Fungus gnat larvae, Thrips larvae, Crane Fly Larvae, Squash Vine Borer Larvae, & more. Introduction Sites: Use indoors or outdoors in potted plants or directly in the soil. Introduction Rates Preventative/Light: 5 million per 300 sq. ft. Moderate/Heavy: 5 million per 50 sq. ft. Seasonal application recommended for prevention. Weekly to monthly application recommended for active infestations. Adjust as needed. Introduction Method: Apply to moist soil using a watering can or sprayer, distributing evenly over the treatment area. Apply during early morning or evening and maintain normal soil moisture levels for two weeks. 53°F+ soil temperature required. Shipping: Nematode powder in poly bag, padded pack with ice pack. 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. Storage: 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.

They worked so well we now use them in our vegetable gardens as well Review: Best fungus gnat eradication! - Every one of my house plants became plagued with fungus gnats after my friend gave me a potted daffodil infested w/gnat eggs. Before finding nematodes I had tried to eradicate the gnats multiple using other methods (barriers on the soil surface, insectacidal soap, watering abstinence, traps). Nematodes were the only product that completely eradicated the eggs and stopped the cycle. I’m frugal, so the price of the nematodes kept me from trying them immediately. But after many months of failed attempts to destroy the tiny infuriating gnats, I gave nematodes a try. The shipping costs were well worth it. Make sure you schedule the package arrival for a day you can get the shipment straight into the refrigerator. I divided the nematodes into 2 batches and “watered them in” a month apart. 95% of the gnats were gone within 2 week of the first application. ## Features - Great enemies to Fungus gnats, root aphids, root nematodes and many more - Can be use around Animal, Pets and Plants ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B086686F4X | | Best Sellers Rank | #160,735 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #212 in Beneficial Pest Control Insects | | Brand Name | NaturesGoodGuys | | Customer Reviews | 4.2 out of 5 stars 195 Reviews | | Manufacturer | NaturesGoodGuys | | UPC | 657994165620 | ## Images ![NaturesGoodGuys Beneficial Nematodes Steinernema feltiae SF - 5 Million - Image 1](https://m.media-amazon.com/images/I/71RqMXicHwL.jpg) ![NaturesGoodGuys Beneficial Nematodes Steinernema feltiae SF - 5 Million - Image 2](https://m.media-amazon.com/images/I/91AKgYTTFuL.jpg) ![NaturesGoodGuys Beneficial Nematodes Steinernema feltiae SF - 5 Million - Image 3](https://m.media-amazon.com/images/I/915mcMNERfL.jpg) ![NaturesGoodGuys Beneficial Nematodes Steinernema feltiae SF - 5 Million - Image 4](https://m.media-amazon.com/images/I/81IB+9bieeL.jpg) ![NaturesGoodGuys Beneficial Nematodes Steinernema feltiae SF - 5 Million - Image 5](https://m.media-amazon.com/images/I/61ZvWfSOlDL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Go natural *by M***S on November 8, 2025* Our house was full of fungus gnats until we treated all our potted plants with beneficial nematodes.

Lots of nematodes... all dead. *by M***J on February 6, 2026* All dead. Lots of nematodes... all dead. Added a small sample of the powder to some chlorine free water and observed under dissecting microscope. Not sure how cold they are supposed to be kept... it has been in the 80s here, but package had a cold pack that had melted and was warm.
