Experts and BHG readers answer.
Chemical products such as halofenozide (sold under the name GrubEx) and imidacloprid (sold as GrubEx Season-Long Grub Control) are available at your local garden center. Both provide good grub control (when used as directed on the label) and have a low toxicity level when it comes to humans, pets, and wildlife. Some gardeners have had good success with natural products such as milky spore; others have had less luck. One reason is that milky spore disease targets Japanese beetle grubs; if other grub species infest your lawn, milky spore disease won?t affect them. Other natural products that can provide some control, though not as consistently as a chemical control, are diatomaceous earth and beneficial nematodes, which are sold under the name Grub-Away.
