Scotts GrubEx1 5,000 sq. ft.
Scotts GrubEx1 Season Long Grub Killer is designed to prevent turf damage by targeting grubs when they are young. A single application can guard lawns for up to four months. The formula also lists effectiveness against caterpillars (armyworms), chinchbugs, and May/June beetles, with annual use potentially helping control Japanese beetle infestations. This product is suitable for lawns up to 5,000 square feet and is often chosen for standard residential turf care. Applications should follow label directions for best distribution and soil contact.
Scotts GrubEx1 10,000 sq. ft.
This larger-size Scotts GrubEx1 option provides the same season-long grub control and multi-insect protection as the smaller version but covers up to 10,000 square feet. It’s suitable for bigger yards or multi-zone lawns. The product remains a single-treatment option, with the potential to reduce grub populations for months. As with other Scotts formulations, follow the label for application timing and rate to maximize effectiveness and minimize environmental impact.
Scotts GrubEx1 5,000 sq. ft. (2-Pack)
This 2-pack option is designed for homeowners managing more than one lawn or larger properties with two separate areas. It retains the same four-month protection against grubs and includes the same spectrum of pest control claims as the smaller pack. Review your total area to determine if two applications will be needed or if a single larger coverage product is more cost-effective for your space.
St. Gabriel Milky Spore Granular (15 lb)
St. Gabriel Organics Milky Spore Granular is an organic grub control option designed to reduce Japanese beetle larvae by releasing Milky Spore powder that infects grubs. The product is marketed as season-long and year-round due to the persistent nature of Milky Spore in soil. It is USDA-certified organic, non-toxic, and suitable for use around food crops and residential areas. Application is straightforward, with a single treatment able to begin providing grub suppression after spreading in the lawn or garden beds.
Ortho BugClear Lawn Insect Killer 16,500 sq ft
Ortho BugClear Lawn Insect Killer1 kills listed insects by contact, including grubs, ants, spiders, ticks, fleas, and armyworms. It provides up to six months of ant control (excluding certain ant species). This product is intended to protect lawns, ornamental plantings, home perimeters, and flower beds, offering broad-spectrum pest suppression beyond grubs alone. It is suitable for mid-sized to larger yards with expansive turf areas and garden borders.
Bonide 603 Annual Grub Killer
Bonide 603 Annual Grub Killer is a 6-pound formulation designed for season-long grub control across up to 5,000 square feet. This product emphasizes broad grub suppression for common turf-damaging species. It can be a practical option for homeowners seeking a traditional chemical grub management method with a manageable coverage area and straightforward application. As with other lawn care products, adhere to label guidelines to achieve effective distribution and soil contact.
Buying Guide
Key purchase considerations focus on pest scope, turf size, and application preferences. Coverage area should match your lawn’s square footage to minimize waste and ensure complete protection. Active ingredients and mode of action matter if grubs co-occur with other pests or if you prefer organic options. Organic Milky Spore offers long-term soil persistence but may require time to establish, whereas chemical products provide rapid knockdown and shorter-term control with reapplication cycles. Weather and soil conditions influence effectiveness; apply when soil is moist but not waterlogged for best uptake.
Other factors include safety for children and pets, especially in homes with play areas or edible gardens. Some products offer extended control against additional pests like ants or armyworms, which can be advantageous in multifunctional landscapes. Consider your yard’s layout—larger, multi-zone lawns may benefit from higher-coverage formulations, while smaller plots might work well with single-dose products. Finally, review application frequency and any required soil-temperature thresholds to optimize results and reduce environmental impact.
The selections above provide options across conventional and organic approaches, different coverage needs, and various pest-control profiles. When choosing, balance how quickly you need relief from grubs with how long you want protection and how your garden habitat interacts with beneficial insects.
