How To Apply

NemaKnightsTM Biological Insect Control:

Traditional nematode formulations have been successful but limited biocontrol for over two decades. NemaKnights™ are the next generation biocontrol, with an exclusive 6-month shelf-stable and slow-release formula for grubs, vine weevils and other garden pests.


Use outdoors in damaged lawn areas. Treat gardens around the base of plants, where damaged areas or insects appear. To apply, remove the bottle cap and peel off the safety seal. Reattach the bottle cap and flip open the easy flip shaker lid portion. Shake the product directly onto the soil where pests are present. After application, water plants for the next three days to release the Steinernema nematodes. For outdoor use, spot treat where pest damage is present. May be used for all white grubs (Japanese beetle, European chafer and May/June beetle larvae). Also effective on sod webworms, caterpillar and other lawn soil pests.

For best results

Apply 10-14 days after first application for heavily damaged areas.


Keep product out of direct sunlight. Store at or below room temperature.
