The Gardening Naturally Leatherjacket Nematodes are designed for homeowners and gardeners dealing with turf damage caused by crane fly larvae. This biological control offers a highly effective, non-toxic way to reduce leatherjacket populations and restore lawn health, though success requires precise timing and consistent soil moisture maintenance.

The product must be stored in the refrigerator immediately upon arrival to keep the live organisms viable.
Yes, these nematodes are a biological control and are safe to use around pets, children, and pollinators.
Each pack is sufficient to treat up to 100 square meters of lawn.
Nematodes require moisture to move through the soil. If the area dries out, their effectiveness will be significantly reduced, so you must keep the ground damp for 7 days.
Verify that the soil stayed moist for the full 7-day period following application and that the soil temperature was sufficient for activity.
Ensure all fine-mesh filters in the watering can or hose-end sprayer are removed, as they will trap the nematodes.
Because this is a live biological product, immediate storage is required. Place the pack in your refrigerator as soon as it arrives to maintain the viability of the organisms. Avoid freezing or excessive heat.
Compatibility is universal across most lawn types, but ensure the soil temperature is sufficient for nematode activity (generally above 10 degrees Celsius). When applying, remove any fine-mesh filters from your sprayer to prevent the nematodes from being filtered out of the solution. Keep the treated area moist for 7 days post-application to ensure the nematodes thrive and effectively navigate the root zone.
