10 Best Lawn Grub Killers 2026 in the United States

Scotts GrubEx1 Season Long Grub Killer is a solid choice for those looking to protect their lawns from grubs and other pests for an extended period. A major strength is its ability to kill grubs and other insects such as caterpillars, chinchbugs, and Japanese beetles, providing protection for up to 4 months with just one application.

Its granular form makes it easy to apply to a dry lawn in the spring or early summer, covering a substantial area of up to 5,000 square feet per 14.35-pound bag. The active ingredient, Chlorantraniliprole, is effective in targeting young grubs before they can damage your lawn. However, it is important to note that the product's impact on the environment and its safety for pets and children should be considered.

While Chlorantraniliprole is generally considered safer for non-target species compared to other insecticides, it is still wise to follow all safety instructions and keep pets and children away from treated areas until the product has settled. Additionally, there is no mention of the residual effect beyond the 4-month period, so reapplication may be necessary for year-round protection. For those environmentally conscious, understanding the full environmental impact might require further research. In summary, Scotts GrubEx1 is a practical and effective solution for lawn pest control if used according to guidelines and with consideration for safety measures.
