Buying Guide
Key purchase considerations help align choices with your space and infestation level:
- Active ingredient and mode of action: Diatomaceous earth-based powders work by desiccating insects, while other dusts provide contact-kill action. Choose based on whether you prefer a mechanical kill or a chemical approach with longer residual effects.
- Application method: Look for powders with a duster or simple pour-and-dust options for cracks, crevices, and mattress seams. Ease of application improves coverage and consistency.
- Coverage area: Larger bags offer cost efficiency for expansive homes. For apartments, consider smaller, lighter packs with long-lasting residuals in key hiding spots.
- Safety and compatibility: Plant-based and low-toxicity powders are preferable for households with children and pets. Follow label directions for safe use around bedding and living areas.
- Residue and cleanup: Some powders leave minimal residue, while others may require vacuuming or sweeping after treatment. Plan for post-treatment cleanup in sleeping zones and furniture.
- Integration with other methods: Powders often pair with traps or killer sprays as part of a broader plan. Consider whether you want a standalone product or a system approach (as with Ortho’s line).
