Buying Guide: Key Considerations for Selecting Lawn Insect Treatments

  • Coverage area and application method: Choose formulations that match your yard size (granules, ready-to-spray, hose-end) and your preferred application style. Larger yards may benefit from products with higher coverage per bag.
  • Target pests: Review which insects are most problematic in your region (ants, ticks, fleas, grubs, chinch bugs, etc.) and select a product with proven efficacy against those pests.
  • Timing and seasonality: Some products emphasize early-season disease and growth periods or extended pest protection. Consider lawn green-up timing and any seasonal spraying needs.
  • Contact vs. residual kill: Some products kill on contact, others offer lasting protection for weeks or months. Depending on your pest pressure, you may want both immediate and ongoing control.
  • Safety and impact: Check labels for environmental impact, non-staining properties, and any restrictions around ornamental plants, vegetables, or pets. Ensure compatibility with your home perimeter and garden plants.
  • Combination products: Dual-action fungicide/insect control can simplify treatment in regions with both disease pressure and insects, but ensure the product suits your lawn type and climate.
  • Restrictions and exclusions: Note any exclusions (e.g., certain ant species) and follow label directions precisely to maximize effectiveness and safety.
