How long does it take for beneficial nematodes to work?
In general, 3-7 days for caterpillars such as cutworms, army worms, sod webworms. For grubs and weevils such as Japanese beetle, black vine weevil and billbugs feeding stops within 3 days with maximum control occurring over 2-4 weeks. Nematodes disintegrate the pests from the inside out.
How to apply beneficial nematodes
- Select a nematode species that is most effective against the target pest.
- Apply when the caterpillar or grub stage of the pest is present and active.
- Do not apply if the soil temperature is below 60°F.
- Irrigate before application.
- Animal manures are an important food source for earthworms. They eat living organisms such as nematodes, protozoans, rotifers, bacteria, fungi in soil. Worms will also feed on the decomposing remains of other animals. A. They don't have teeth but they have strong mouth muscles.
- Vertebrate Predators. Birds such as grackles, meadowlarks, starlings, cardinals, and catbirds have been reported as significant predators of JB adults. In addition, pheasants, chickens, ducks, geese, and guineas readily feed on the beetles. Starlings, grackles, crows, and gulls also devour large numbers of JB larvae.
- Spray once each week until no more grubs surface. You can introduce the fungal disease milky spore into your lawn to control the Japanese beetle larvae population. Try planting garlic, rue, or tansy near your affected plants to deter Japanese beetles.
Beneficial nematodes are microscopic, non-segmented worms that attack soil-dwelling insects without harming plants. We have had customers ask if beneficial nematodes are harmful to humans, pets and earthworms and the answer to that is: “NO!”
- Nematodes move by contraction of the longitudinal muscles. Because their internal pressure is high, this causes the body to flex rather than flatten, and the animal moves by thrashing back and forth. No cilia or flagellae are present.
- The smallest nematodes are microscopic, while free-living species can reach as much as 5 cm (2 in), and some parasitic species are larger still, reaching over 1 m (3 ft) in length. The body is often ornamented with ridges, rings, bristles, or other distinctive structures. The head of a nematode is relatively distinct.
- Mix with water and spray or sprinkle on the soil along garden plants or lawn. Put the contents of the Beneficial nematodes in a bucket of water and stir to break up any lumps, and let the entire solution soak for a few minutes. Application can be made using a water-can, irrigation system, knapsack or sprayer.
There it releases its bacteria, which multiply and kill the host insect. The nematodes develop into adults on bacterial cells in the insect cadaver and reproduce. Infective juvenile nematodes in soil enter insect body through natural openings.

- Use Beneficial Nematodes to Control Grubs, Fungus Gnats, Fleas and Over 200 Other Soil Developing Pests! ARBICO's Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world.
- Their digestive system includes a mouth, pharynx, intestine, rectum and an anus. Reproduction & Development: Roundworms reproduce sexually and have internal fertilization. They also have separate sexes.
