Buying Guide

  • Coverage area: Choose a product that matches the lawn size. Larger lawns may benefit from bulk or 10,000 sq ft options.
  • Active ingredients: Imidacloprid-based products are common for grubs but review any sensitivities for pets or pollinators. Consider alternatives if you prefer non-neonicotinoid options.
  • Longevity: If you face repeated grub pressure, select season-long formulas that last several months.
  • Target pests: Most grub killers also address related pests like armyworms, chinchbugs, and beetles. Confirm listed pests align with your concerns.
  • Application method: Granular formulations are straightforward for lawns; liquid concentrates offer versatile application but may require equipment and precise mixing.
  • Safety and timing: Apply during appropriate seasons when grubs are young and before damage occurs. Follow label directions for pets, children, and irrigation needs after application.
  • Environment and plant health: Consider impact on beneficial insects and overall lawn health. Integrated pest management favors selective products and proper mowing, watering, and aeration practices.
