Scotts GrubEx1 Season Long Grub Killer (5,000 sq. ft.)
Scotts GrubEx1 is designed to prevent turf damage by killing grubs when they are young. A single application can protect up to four months. The product also helps control caterpillars (armyworms), chinchbugs, May/June beetles, and more. Regular annual applications may aid in controlling Japanese beetle infestations. This granular treatment is suitable for lawns up to 5,000 square feet, helping reduce grub activity before damage occurs.
Key features include season-long protection, a focused approach to early grub stages, and additional pest controls listed by the manufacturer. For best results, follow label directions regarding watering and application timing to ensure soil contact with larvae.
Scotts GrubEx1 Season Long Grub Killer (10,000 sq. ft.)
This larger-volume variant extends GrubEx1 protection to lawns up to 10,000 square feet. Like the 5,000 sq. ft. version, it aims to prevent turf damage by killing grubs early and offers season-long control for up to four months. The formulation targets common lawn pests including caterpillars, chinchbugs, and May/June beetles, with potential benefits for Japanese beetle management when used annually.
Applications should be aligned with the lawn size and soil conditions to maximize soil contact. Regular monitoring of grub activity helps determine whether reapplication is needed later in the season.
Scotts GrubEx1 Season Long Grub Killer (5,000 sq. ft.) 2-Pack
This 2-pack extends the 5,000 sq. ft. grub protection, offering two applications to cover multiple seasons or to address large lawn areas in stages. The product’s core benefits include killing grubs when they are young and providing up to four months of season-long control, with additional pest coverage such as armyworms and beetles as listed on the label. Consistent application in spring or early summer aligns with peak grub activity for optimal results.
Pro Grub Control – 32oz (Imidacloprid)
Pro Grub Control by Liquid Harvest uses a 21.4% Imidacloprid concentration to combat grub larvae and other pests across lawns, trees, shrubs, and landscape ornamentals. The product is versatile, allowing turf applications, foliar spraying, or soil applications depending on pest targets. Its concentrated liquid form enables targeted treatments for localized grub problems and integrates with broader landscape pest management plans. As with any chemical insecticide, follow label instructions for safe handling and application rates.
Buying Guide: Grub Control Considerations
- Coverage and lawn size: Match the product’s stated coverage with your yard to avoid over- or under-application. Multi-pack options can help cover large or divided areas.
- Active ingredients: Granular grub treatments and liquid concentrates use different active ingredients. Imidacloprid-based products provide broad-spectrum control but may require careful application timing around pollinator activity. Always check local regulations and label guidance.
- Season-long protection: Look for products that promise season-long control (typically up to 4 months). Timing is crucial: apply when grubs are young and before they cause visible damage.
- Pest spectrum: Some products target grubs specifically, while others also address caterpillars, beetles, chinch bugs, and armyworms. Consider your lawn’s pest history when choosing.
- Application method: Granular products require watering in after application to activate, while liquids may require mixing and precise application rates. Ensure your spreading equipment and instructions align with your lawn’s needs.
- Safety and environment: Follow label directions to minimize impact on non-target organisms, including beneficial insects. Check for any local restrictions on pesticide use, especially near water sources and flowering plants.
- Resistance and rotation: If grub problems persist, consider rotating products with different active ingredients to mitigate resistance and maintain effectiveness over multiple seasons.
