Ortho BugClear Lawn Insect Killer 10 lb
Best for small to medium lawns needing fast, long-lasting ant control. The product provides up to six months of ant protection (excluding pharaoh, carpenter, and harvester ants) and three months residual protection for other listed pests. Apply with a compatible spreader and water in to activate. Use when you notice insect activity or damage around the home perimeter, flower beds, or edible plant areas.
Caution: Not effective against all ant species; performance can vary by soil and moisture conditions. Suitable for lawns and ornamental plant areas but avoid applying during periods of heavy rainfall or extreme heat guidance per label directions.
Best for buyers seeking a convenient, ready-to-use solution with broad pest coverage and clear timing for reapplication.
Spectracide Triazicide Insect Killer For Lawns (20 lb)
Best for larger lawns needing broad-spectrum, contact-kill action. This 20-pound bag kills more than 100 insect types, both above and below ground, including ants (excluding harvester and pharaoh ants), crickets, armyworms, grubs, and ticks. Apply around the house foundation or across turf as needed, with results visible after treatment. Provides on-contact kill and is suitable for seasonal applications when insects appear or damage is evident.
Caution: Some pests may require multiple treatments for complete suppression. Not all ant species are labeled for control, so verify target pests before application.
Choose this if you need a broad, multi-insect control option for larger properties and frequent pest activity around the home.
Ortho BugClear Lawn Insect Killer 20 lb
Best for medium-to-large yards requiring extended coverage with a similar active profile to the 10 lb version. This 20-pound option provides up to six months of ant control, three months residual for listed pests, and fast-acting protection after application. Suitable for lawns, ornamental plants, and perimeters when paired with a spreader and irrigation to activate.
Limitation: Larger bags may require a broader spreader and careful coverage planning to avoid over-application in borders or steep slopes.
Better for households with bigger lawns seeking the same active ingredients and long-lasting performance as the smaller bag, with more area per bag.
BioAdvanced Complete Brand Insect Killer Granules (10 lb)
Best for homeowners seeking combined surface and subsurface insect control with a single product. The 10-pound bag treats up to 10,000 square feet and kills surface insects like grubs and ticks within 24 hours, while providing up to three months of protection. The two-way formula supports both lawn and soil area pest management and is compatible with broadcast or drop spreaders for easy application.
Caution: Not all resistant pests are listed on every label; verify pest targets before application and avoid applying directly to edible plant beds unless specified.
Choose this if you want a versatile product that addresses both surface and soil-dwelling pests in one step.
Scotts GrubEx1 Season Long Grub Killer (5,000 sq. ft)
Best for preventive grub control with a season-long protection window. One application kills and prevents grubs for up to four months and also controls caterpillars, chinch bugs, and other listed pests when used annually. The product is designed for 5,000-square-foot coverage per bag and works best when used as part of a wider lawn care plan that supports healthy root systems.
Caution: Primarily grub-focused; pests beyond grubs may require additional products or applications for comprehensive control.
Choose this if you are primarily concerned about grub damage and want a dedicated seasonal solution for a specific turf area.
Buying Guide
What size lawn do you have?
Smaller yards benefit from 10–20 lb bags, while larger properties may require multi-bag plans or larger bags to cover the lawn efficiently. Consider your spreader compatibility and how many applications you anticipate per season.
Which pests are you targeting?
Identify common lawn pests in your region (grubs, ants, ticks, crickets, etc.). Some products are broad-spectrum, while others focus on specific pests like grubs or surface insects. Match the product to the primary threat for best results.
Season and timing considerations
Granular products are typically applied when insects become active or when damage is visible. Some products offer season-long protection, while others deliver fast-acting results with shorter residuals. Plan applications around your growing season and irrigation practices.
Coverage and application efficiency
Review the bag’s square-foot coverage and choose a product whose coverage aligns with your lawn size. Use a compatible spreader for uniform distribution and water in after application to activate.
