FAQs
Is Nemasys Leatherjacket Killer safe for my pets?
Yes, because it is a biological control using naturally occurring nematodes, it is safe for pets, wildlife, and humans.
Can I store the product for later use?
No, this is a live biological product and should be stored in the refrigerator and used as soon as possible after purchase.
When is the best time to apply?
Application is most effective in late summer or early autumn when the soil is warm and the leatherjackets are young and active.
Do I need special equipment to apply it?
No, you can use a standard watering can with a coarse rose or a garden hose-end sprayer.
Will this kill other insects in my garden?
Nemasys is specifically targeted toward leatherjackets and does not pose a threat to beneficial insects like earthworms or bees.
How long does it take to see results?
You should observe a reduction in larvae activity within a few weeks, though significant lawn recovery depends on the level of initial damage.
Troubleshooting
Nematodes not effectively reducing larvae population
Verify that soil temperatures were consistently above 12°C and that the soil remained moist for the full two-week period following application.
Solution nozzle clogging during application
Ensure the concentrate is fully dissolved and filtered through a fine mesh or cloth before adding it to the sprayer or watering can.
Product arrived warm in transit
Check the viability of the nematodes; if they have been subjected to extreme heat for an extended time, they may be inactive. Contact support if the package was compromised.

Setup, Compatibility & Care
To prepare the treatment, mix the nematode concentrate thoroughly with water according to the provided ratio. Ensure the soil is aerated if it is compacted, as nematodes require sufficient soil moisture and porous ground to move effectively. When applying, use a coarse rose on your watering can to ensure even distribution across the 100sqm area. Since this is a live biological product, it should be kept refrigerated before use and applied immediately once mixed. Avoid applying during periods of high direct sunlight or drought, as UV rays and dry soil can significantly reduce nematode survival rates.
