Use for spot treatment or mix into soil.

When to use:

Once soil is above 8°C, throughout the growing season April to October, whenever pests are visible and feeding. The best time is in the early morning or evening because the nematodes are sensitive to ultraviolet rays.

When used indoors it can be used throughout the year as preventative measure or when the infestation occurs.

Using the NemaKnights Fungus Gnat control can act as a preventative measure against fungus gnat populations. Beneficial nematodes for fungus gnats allow the issue to be solved at the source as the fungus gnat larvae are eliminated by the nematode once it’s released by the adults. This stops the replication cycle and eventually eliminates the pest once the adults perish.

Nematodes are microscopic naturally occurring soil organisms in the worm family (insect parasitic) which seek out larval stage of soil insects & in the case of slugs infect all stages of the insect. Once a nematode infects a bug, the bacteria released can kill the host in 24-48 hours. Nematodes will survive in the soil as long as there are insects to reproduce in.
