Ortho BugClear Lawn Insect Killer Granules, 10 lb
Best for large lawns where long-lasting ant and insect control is desired. This 10 lb bag provides up to 16,500 square feet of coverage and long-lasting protection, with residual activity against listed pests for months. It starts to work quickly to form a barrier around the lawn and garden perimeters, though some ant species may respond slower.
Who it’s best for: Homeowners with expansive lawns needing enduring protection and fast-acting results against ants, spiders, ticks, fleas, and grubs. It’s suited for perimeter treatment around a home and around ornamental plantings.
Key limitation: Some ant species may require multiple applications for full control, and it does not protect against all ant species. Watering after application activates the granules but may reduce immediate visibility of effect in very damp conditions.
Ortho BugClear Lawn Insect Killer Granules, 20 lb
Best for mid-to-large yards where extended control is needed and application frequency can be reduced. This 20 lb bag treats up to 33,000 square feet and delivers up to six months of ant control plus three months of residual protection for other listed pests. It’s fast-acting and suitable for use around home perimeters and garden beds with water-in activation after spreading.
Who it’s best for: Yard owners seeking a lighter maintenance schedule for a larger area, especially if ants and other listed pests are persistent across seasons.
Limitation: Heavier bag means more product to handle; ensure you have a spreader compatible with the product and follow watering instructions post-application.
BioAdvanced Complete Brand Insect Killer Granules
Best for integrated control of surface and soil insects in a single product. This 10 lb bag treats up to 10,000 square feet and provides three months of protection. It kills listed surface insects and also targets soil-dwelling pests like grubs and ticks, with ready-to-spread granules suitable for broadcast or drop spreaders.
Who it’s best for: Homeowners seeking a two-way formula that covers both above-ground and subsurface pests, including mosquitoes and other listed outdoor pests.
Limitation: May require reapplication after heavy rainfall or in high-traffic areas to maintain protection.

Best for broad-spectrum, season-long lawn protection. This 20 lb bag targets more than 100 insect types, both above and below ground, including ants, crickets, armyworms, cutworms, and grubs. Apply on lawns and around foundations for defense throughout the growing season.
Who it’s best for: Yard care routines requiring extensive pest coverage with a single product for multiple insect types across seasons.
Limitation: Some lawn-damaging ant species are excluded in the label; plan to monitor and reapply as needed per application intervals.
Cedarcide Original Cedar Granules
Best for pet-friendly, natural deterrence. These cedar granules release a natural aroma that repels many insects, including mosquitoes, fleas, and spiders, with a 100% natural cedar base. They are safe for families and pets when used as directed and are easy to sprinkle around lawns, patios, and perimeters.
Who it’s best for: Gardeners preferring natural repellents and scent-based deterrence over chemical insecticides. Ideal where children and pets frequent treated areas.
Limitation: Cedar granules may require more frequent replenishment in high-traffic use areas or in very windy conditions to maintain odor-driven deterrence.
Buying Guide: Key Factors In Choosing Yard Bug Granules
- Size of the area: Larger lawns benefit from bigger bags or bundles; smaller yards may do well with 10–20 lb options to minimize waste.
- Target pests: Identify whether you need protection from ants, grubs, ticks, fleas, or a broad spectrum; choose a product labeled for those pests.
- Protection duration: Consider how long you want protection per application—some offer months of residual activity, others are fast-acting but shorter-lasting.
- Application method: Spreader compatibility and ease of spreading affect coverage uniformity and labor; ensure the product suits your spreader type.
- Environment and pets: If you have kids or pets, look for pet-safe and low-toxicity formulas; cedar-based granules offer a natural deterrent without harsh chemicals.
- Water activation: Some products require watering in after spreading to activate. Plan outdoor activities accordingly and avoid irrigation conflicts.
