Scotts GrubEx1 Season Long Grub Killer – 5,000 sq ft

Scotts GrubEx1 is a season-long grub killer designed to prevent turf damage by targeting grubs when they are young. A single application can protect a lawn for up to four months, reducing the risk of root feeding that weakens turf. The product also helps control caterpillars (armyworms), chinchbugs, and May/June beetles, among others. Annual use may assist in managing Japanese beetle infestations. With a high-availability granule formulation, it distributes evenly across the turf to reach feeding grubs in the root zone.
Ideal for homeowners seeking straightforward, long-lasting grub protection, this Scotts product is often chosen for small to medium lawns up to 5,000 square feet. Application timing matters: apply when grubs begin to emerge and before peak feeding periods. It’s compatible with standard lawn care practices, and the granular format makes for easy spreading with a broadcast spreader. Environmental considerations include avoiding runoff into storm drains and following label directions for safe use around pets and children after drying.
Scotts GrubEx1 Season Long Grub Killer – 10,000 sq ft

This larger-gridded version of the Scotts grub killer extends protection to 10,000 square feet, maintaining the same four-month grub-killing window as the smaller bag. It targets grubs at their early life stages, helping to prevent root damage and turf thinning. The product also provides control over a range of pests including armyworms and chinchbugs and supports Japanese beetle management with annual applications. For homeowners with bigger yards, this option reduces the need for multiple bags while offering consistent seasonal control.
As with any granular insecticide, precise application is critical. Use a lawn spreader to ensure even coverage, and water after application as advised by the label. Consider scheduling around peak grubs’ emergence in your region, and avoid application during periods of drought or extreme heat for optimal results. This product pairs well with routine lawn maintenance programs that prioritize soil health and robust turf growth.
BioAdvanced Season Long Grub Control – 10 lb

BioAdvanced Season Long Grub Control comes in ready-to-spread granules designed to cover up to 5,000 square feet per bag and start protecting your lawn immediately. It claims season-long control against a broad spectrum of lawn insects, including ants, ticks, mole crickets, and European crane fly larvae, alongside grubs. This broad-target approach can simplify lawn pest management by combining grub protection with other common lawn insect controls.
Consumers evaluating this option should consider spray or broadcast timing to maximize soil contact with young grubs. The product’s coverage aligns well with mid-sized lawns and households seeking a versatile insecticide that supports ongoing turf health. Always observe safety precautions, especially around children and pets, and follow watering guidelines to ensure active ingredients reach the root zone effectively.
Scotts GrubEx1 Season Long Grub Killer – 5,000 sq ft (2-Pack)

This two-pack version delivers the same four-month grub protection for a total of 10,000 square feet of lawn, offering improved value for households with larger yards or those who prefer fewer shipments. The product targets grubs when young and also helps manage a spectrum of other soil-dwelling pests that damage roots and reduce turf vigor. Regular annual treatments can help suppress recurring infestations and keep lawns resilient through peak grub seasons.
Users should space applications as directed, maintain appropriate watering after spreading, and consider integrating with a broader lawn care plan that supports soil microbiology. The 2-pack option is convenient for seasonal planning and ensures you have ready supply for subsequent seasons without reordering mid-year.
Pro Grub Control – 32oz Concentrate (Imidacloprid)

Pro Grub Control by Liquid Harvest is a concentrated insecticide featuring 21.4% Imidacloprid.

The concentrate form can cover multiple applications, enabling deeper soil penetration to reach grubs during their active feeding stages. This product is suitable for homeowners seeking a potent, adjustable solution with a range of application methods.
When using a concentrate, accurate measurement and mixing are essential to ensure effectiveness and safety. Follow label directions closely, observe any compatibility considerations with existing lawn treatments, and monitor for any signs of environmental sensitivity. This option appeals to those who need scalable dosing based on lawn size and pest pressure.

- Application method: Granules are easy with broadcast spreaders; liquids and concentrates offer flexibility for soil drenching or foliar sprays. Consider your spreading equipment and comfort level.
- Safety and timing: Follow label directions, including watering requirements after application and restrictions around pets and children during and after treatment.
