Beneficial Nematodes

Beneficial Nematodes are microscopic, nonsegmented worms that occur naturally in soil all around the world. Once they are released, the nematodes seek out host insects and enter their prey through body openings, injecting them with lethal bacteria, then feeding on the resultant "goo".The nematodes reproduce and their offspring feed on the insect cadaver and emerge to seek out new hosts. The endo-toxin generally results in death of the host insect within 48 hours.

Nematodes are easy to use. They are shipped in a dry powdery clay formulation that is easily mixed with water. The solution can be applied using a watering can; hose end, backpack, or pump sprayers; or through irrigation or misting systems. Always release early in the morning or late afternoon when temperatures are cooler and away from direct sunlight to avoid exposure to ultraviolet rays and the drying effects of the sun. It is good to pre-moisten the soil before application and to water the area where application was performed afterwards. Soil should be moist, but not saturated.

Generally, 10 million of Beneficial Nematodes will effectively treat approximately 900 sq. ft. of conventional garden rows or up to 2500 sq ft broadcast. Release nematodes every 3-6 weeks or until infestation subsides.

Nematodes can be stored in a refrigerator (do not freeze!) for up to 2 weeks, but it is best to use them as soon as possible, because they are somewhat perishable. If they start to smell bad, they're on their way out.

The nematode enters the host and kills it within 24 to 48 hours. It then reproduces within the hose and searches for new hosts. This hunt and seek cycle provides long-term control.
