Buying Guide: Key Points To Consider
- Target pests: Determine whether you need grub control, ant control, or a broad insect killer. Some products emphasize grub prevention, others target ants and ticks.
- Coverage area: Match product size to your lawn. Large-yard buyers may prefer 20 lb or bigger bags; smaller lawns can use 10 lb or 5,000 sq ft formats.
- Protection duration: If you want season-long protection, look for products advertising 3–6 months of residual effect. Consider reapplication timing for best results.
- Application method: Choose between granular spreader-based products and ready-to-spray liquids based on your setup and preferences.
- Safety and environment: Follow label directions for outdoor application around plants and water features. Check for pets’ access after application as recommended.
