Scotts GrubEx1 Season Long Grub Killer — 4 Month Protection
Scotts GrubEx1 is designed to prevent turf damage by targeting grubs in their early life stage. A single application can protect lawns for up to four months, making it suitable for seasonal grub activity. The formula also addresses other lawn pests such as armyworms, chinchbugs, and May/June beetles, with annual application helping to manage Japanese beetle infestations. This product is often recommended for standard turfgrass areas up to 5,000 square feet.
The approach is preventative, focusing on grubs before they start feeding on roots. Homeowners typically apply in the spring or early summer, depending on local pest cycles. While the label highlights control for several insects, always follow application directions for timing, watering, and any re-entry restrictions after application.
Scotts GrubEx1 Season Long Grub Killer — 10,000 Sq. Ft.
Designed for a larger lawn, this GrubEx1 option provides the same active protection period—up to four months—covering up to 10,000 square feet. The formulation targets grubs when they are young, aiming to curb turf damage before roots are compromised. It also addresses other common lawn pests, and regular annual applications can contribute to longer-term suppression of Japanese beetles. This variant suits bigger yards or multi-lawn properties where a single treatment is preferred for broad coverage.
Scotts GrubEx1 Season Long Grub Killer (2-Pack)
This multi-pack option provides two treatments, each capable of protecting lawns for up to four months. It maintains the same grub-first strategy, with added convenience for homeowners who prefer staggered, long-season protection or want to cover multiple lawns. As with single-pack applications, follow product directions for timing, watering, and reapplication cycles to maximize efficacy against grubs and related pests.

The product emphasizes non-staining performance on many home exteriors, depending on age and cleaning, which can influence its suitability for certain home sites.
Buying Guide: Key Purchase Considerations
- Target pests and lifecycle: For grub-specific control, products marketed as grub killers with preventive action are beneficial. If your lawn faces multiple pests, consider a broad-spectrum option with documented efficacy against grubs, armyworms, and beetles.
- Coverage and lawn size: Choose products that match your lawn area. Some options cover 5,000 sq ft, others up to 10,000 sq ft or more. For larger properties, multi-pack or larger-label formulations can reduce reapplication frequency.
- Active ingredient and mode of action: Imidacloprid-based products offer systemic protection, while contact killers act on contact. Depending on your lawn’s plant diversity and soil conditions, you may prefer one approach over another or a combination approach within an integrated pest management plan.
- Application timing: Grub pressure often aligns with seasonal cycles. Read labels for optimal timing windows (spring, early summer, or mid-season applications). Flexible timing can help align with regional pest peaks.
- Watering and re-entry: Some products require watering after application, while others specify waiting periods before foot traffic. Ensure compatibility with your household and pet schedules.
- Environmental considerations: Consider the potential impact on non-target insects and pollinators. Use targeted applications, follow label directions, and explore products with lower environmental footprints when possible.
- Lawn type and landscape: If you have ornamental plants, trees, or vegetable beds nearby, select products labeled for use around these settings and follow any buffer zones or application restrictions.
- Long-term control vs. immediate knockdown: For ongoing grub pressures, long-lasting formulations and annual reapplication plans may offer more consistent protection than short-term solutions.
- Safety and handling: Always wear protective gear as recommended on the label, store away from children and pets, and store in a secure location to prevent accidental exposure.
