The best way to kill grubs in your lawn, along with other lawn pests is with beneficial nematodes.
These microscopic grub killing worms are harmless to humans, animals, plants and earthworms. Beneficial nematodes can be used against a wide variety of grubs and other soil pests like fly larvae, flea beetles, cutworms, weevils, cockroaches, fleas and about 200 other pests.
Once you introduce the nematodes into your lawn, they actively search out lawn pests and enter their body. The nematode releases a toxic bacterium that kills the pest and then feeds on the insect.
When you purchase nematodes, they should be kept in a refrigerator until you are ready to disperse. The nematodes are microscopic and usually come in a container with millions inside.
You can spread the nematodes into your lawn with a hose end sprayer, a watering can or pump sprayer.
Water your lawn well before you introduce the nematodes. It must be overcast or dust when they are applied. Strong sunlight will kill nematodes.
If you are using a hose end sprayer, it will take 5 to 10 minutes to disperse into a 2,500 square foot lawn.
Nematodes need moisture to move into the soil. It is important to water your lawn every day for at least a week after an application.
These nematodes are from the Environment Factor.
