Predatory nematodes attack lawn pests such as billbugs, sod webworms, and white grubs.

 

Nematodes are parasites that kill hosts, such as this grub, within 48-hours.  Some nematodes attack surface pests; others attack soil-dwelling pests.  Choose the correct type for your pest.

 

Nematodes arrive by mail in a sponge.  To apply, place the sponge in a container of cold water and wring it several times to release the nematodes.  Apply with a watering can or sprayer.
