Buying Guide

- Coverage and application: Check square footage coverage per container and whether the formula is granular or liquid to match your yard size and watering practices.
- Safety and compatibility: Verify pet safety, biodegradability, and whether the product is food-grade or suitable for use around plants and children.
- Longevity and reapplication: Some products offer gradual, persistent protection; others may require more frequent application after rain or irrigation.
- Environmental impact: Favor eco-friendly, natural formulations that minimize soil disruption and avoid non-target wildlife harm.
- Ease of use: Consider packaging, dilution requirements, and whether the product is ready-to-use or requires mixing.
