Buying Guide
What should you consider when choosing a flea killer for your yard?
- Treatment type: Ready-to-use sprays vs. granules vs. concentrates. Sprays are convenient for spot treatments and quick coverage; granules work well for large lawns; concentrates offer value but require a sprayer.
- Coverage area: Measure your yard to choose a product that covers the entire space or focus on high-traffic areas like patios and kennels.
- Active ingredients: Plant-based and botanical formulas are gentler on pets and plants but may require more frequent applications. Synthetic formulas often provide longer-lasting protection.
- Safety and pets: Look for products labeled safe for pets when used as directed. Consider separate formulations for yards with vegetable gardens and children’s play areas.
- Reentry time: Some products require no wait time after spraying, while others advise waiting a few hours. Read directions for reentry and watering requirements.
- Environment and plants: If you have vegetable beds or flower gardens, verify compatibility with surrounding plants and avoid drift to sensitive species.
- Application method: Hose-end sprayers simplify large-area coverage; granular products are best for even lawn distribution; always water in granules if required by the formula.
