| Is there an effective way to get rid of grubs in our yard without killing the earthworms? |
| One product is made from beneficial nematodes, which are naturally-occuring soil microorganisms (and not the same as the pest nematodes). These are usually applied in the spring. Available from Burpee under the name Nature Gard for Lawns. Another product is milky spore powder, a naturally-occuring bacteria that kills grubs; you simply apply the powder in a grid pattern on your lawn. The powder is harmless to earthworms and other creatures. The bacteria will continue to multiply, and will keep working for up to 20 years. (The results won't be immediate, however; it will take some time to notice a decline in the grub population.) Available from Gardener's Supply, 1-800-863-1700; www.gardeners.com |
