Buying Guide: Key Purchase Considerations
- Target pests: Identify the insects causing damage (grubs, ants, armyworms, ticks, etc.) and choose a product labeled to control those pests.
- Area coverage and application rate: Check treated square footage and how often you’ll need to reapply. Some products offer season-long protection, others require more frequent use.
- On-contact vs. long-term control: On-contact formulas kill pests present at the time of application, while some products offer extended residual protection for ongoing defense.
- Lawn vs. landscape applicability: If you want broad protection for lawns and shrubs, consider concentrates or multi-target formulas designed for landscapes as well as turf.
- Safety and labeling: Follow all label directions, including recommended weather conditions and water restrictions. Wear protective gear as advised and keep pets and children away during application if required by the label.
- Environmental considerations: Some formulations may be more suitable for lawns with pets or certain soil types. Assess the risk of runoff and choose products with EPA-registered claims suitable for your environment.
- Storage and handling: Store in a dry, cool place and seal tightly to maintain efficacy. Dispose of leftover product per label guidelines.
- Application timing: For grubs, apply when grubs are small and vulnerable. For ant and other pest pressures, align applications with peak activity periods for best results.
- Cost and convenience: Compare price per square foot and the convenience of mixing concentrates versus ready-to-use granules to fit your budget and schedule.
Across these selections, homeowners gain flexible options—granular formulations for immediate, ground-level control and concentrates for broader landscape protection. When selecting, align product capabilities with yard size, target pests, and maintenance preferences to optimize lawn health and curb appeal throughout the growing season.
