Nematodes are microscopic roundworms that occur naturally in the soil. While some species are harmful, there are those that have proven to be quite useful. Beneficial nematodes attack pests that dwell in the soil. This process takes a minimum of 3 days with maximum control seen after about 2-4weeks.
Some of the pests controlled by nematodes include
• Sod webworms
• Japanese beetle
• Black wine weevil
• Bean weevil
• Banana moth
• Winter moth
• Fungus gnat
