Nema-Jet Sprayer

The Nema-Jet is the easiest way to naturally control insects like fungus gnats, fleas, grubs, and many more. Apply at dusk if you can, or in the late afternoon or evening.

1. Mix the nematodes thoroughly with clean, cold water: ⅓ cup of water for every 5 million nematodes. Let it sit for 20 minutes, then mix again right before you apply.
2. Connect the sprayer to your hose with the control knob set to OFF, then turn on the water.
3. Pour the nematode mixture into the bottle.
4. Turn the control knob to WATER and water the area to be treated.
5. Turn the control knob to ON to apply the nematodes. Swirl the bottle now and then to keep the nematodes mixed. Each cup of mixture treats about 600 sq ft.
6. If the bottle doesn't hold all of your mixture, refill it and repeat.
7. Turn the knob back to WATER and water the treated area again to wash the nematodes into the soil.
