Ortho Lawn Insect Killer Granules - Season-Long Yard Protection

Our review of Ortho Lawn Insect Killer Granules finds it best for homeowners who want a single, easy application to protect large yards and garden beds from common pests. The standout reason to consider these granules is their ability to create a broad bug barrier that claims up to three months of control and treats up to 20,000 sq. ft., which makes this a practical choice for medium to large properties where ease of use and long residual control matter most.

Key Features

• Wide coverage: A single 20 lb bag treats up to 20,000 sq. ft., so homeowners can cover large lawns without buying multiple bags.
• Long residual control: The formula provides up to three months of outdoor insect control for listed ants, spiders, ticks and more, reducing the need for frequent reapplications.
• Kills above and below ground: Granules act on contact and can control soil-dwelling pests as well as surface insects to help limit reinfestation.
• Use around plants and foundation: Labeled for lawns, flower and vegetable gardens and around home foundations to create a protective barrier.
• Simple application: Apply with a Scotts spreader, then water thoroughly and allow treated areas to dry before people and pets re-enter for straightforward use.

Who It's For

This product is aimed at homeowners with medium to large yards who want broad, season-long protection against a wide range of common pests including ants, fleas, ticks, spiders and grubs. It suits people who prefer a granular application they can spread themselves and who want to treat lawn, garden and perimeter areas without frequent touch-ups.

Those who should look elsewhere include gardeners needing organic solutions or people seeking targeted insect control for a single, specific pest not listed on the label. Also, small urban balconies or tiny lawns may be better served by smaller, lower-coverage products.

Pros & Cons

Pros

• High coverage lets one bag treat large areas, saving time and trips to the store.
• Three-month residual control can reduce how often you need to reapply through the season.
• Versatile use around lawns, flower and vegetable gardens and home foundations creates a wide protective barrier.

Cons

• Effectiveness is reported as mixed by some users, so performance may vary with local pest pressure and application timing.
• Not an organic option; homeowners seeking natural alternatives will need a different product.
