10 Best Insecticide Grub Killers 2026 in the United States

Scotts GrubEx1 Season Long Grub Killer is a granular insecticide that uses Chlorantraniliprole as its active ingredient to target grubs and other lawn-damaging insects such as caterpillars, chinchbugs, and beetles. One of its notable strengths is its long-lasting effectiveness, providing protection for up to 4 months with just one application. This product is suitable for large lawns, as one 14.35 lb. bag can cover up to 5,000 sq. ft. It is designed to be applied to a dry lawn in the spring or early summer, which is convenient for seasonal lawn maintenance schedules.

However, the granular form requires careful application to ensure even coverage. Safety-wise, it’s important to follow the instructions closely, especially if you have pets or children who play on the lawn. While the product is effective, its environmental impact should be considered, as it involves chemicals that might affect the surrounding ecosystem if not used properly. This product is best suited for homeowners with larger lawns who are looking for a long-term, once-per-season solution to grub and insect control.

It comes in granular form, which makes it easy to apply using a Scotts Spreader. Users will appreciate that this product covers a large area of up to 16,500 square feet, making it suitable for sizable lawns and gardens.

One of the standout features is its ability to provide up to 6 months of protection against ants, although it does exclude certain types such as pharaoh, carpenter, and harvester ants. This extended control can save users from frequent reapplications, adding to its convenience. Additionally, it is suitable for use on lawns, ornamental plants, home perimeters, flower beds, and specified vegetable plants, offering flexibility in its application. However, users should ensure they water the area after application to activate the granules effectively.

In terms of safety, it is important to follow the instructions closely to avoid any potential harm to pets or humans. While the product is effective against a broad spectrum of insects, it has a residual environmental impact, which might be a concern for eco-conscious users.

The product is in granular form, making it easy to spread over large areas and it covers up to 5,000 square feet, which is suitable for most residential lawns. Once applied, it starts to work immediately and offers season-long protection, which means you won’t need to reapply frequently. This is a significant advantage for those looking for a low-maintenance solution to insect problems.

However, it's important to note that the safety and environmental impact of Lambda-cyhalothrin should be considered. While effective, this chemical can be harmful to beneficial insects, pets, and even humans if not used as directed. It's recommended to use protective gear during application and to keep children and pets away from treated areas until the granules have been watered in and the lawn has dried. Additionally, while the product is convenient and highly effective, its reliance on synthetic chemicals might not be the best choice for those seeking an eco-friendly option.
