Broad Spectrum Pest Control Starting At $40, shipping included! Control Grubs, Fungus Gnats, Fleas and Over 200 Other Soil Developing Pests!
ARBICO's Beneficial Nematodes are worm-like, naturally occurring microscopic organisms found throughout the world. There are nematode varieties that live in land, water, and the bodies of living things. In fact, nematodes are so ubiquitous that (according to a 2019 study) scientists have determined that there are 57 billion nematodes for each human on earth. The type of nematode that we sell here at ARBICO are the type that prey on insects, known as Entomopathogenic Nematodes (EPNs). Specifically, soil-dwelling EPNs. They control over 200 pests, including grubs, fungus gnats and fleas. EPNs parasitize insect pests that have soil dwelling larval or pupal stages; however, they have been known to parasitize above-ground stages of certain pests as well. Their wide range of prey makes them exceptional for general pest control.
If you are planning a chemical-free or organic garden our Beneficial Nematodes are an excellent choice for soil developing pest control. They can be used in a wide range of growing environments, including on indoor plants (for fungus gnats) as well as in gardens, lawns, orchards, vineyards, greenhouses, row crops, pastures and more. If you are treating for a specific pest, you may use our beneficial nematode selection chart to select the correct species of nematode for control. Application Instructions, effective temperature ranges, storage information and more can be found in the Beneficial Nematode FAQs. If you prefer some expert advice before you buy, you can always call one of our biocontrol consultants at 1-800-827-2847; they will be happy to help.
