Buying Guide

Check active ingredient and label

Confirm the concentrate lists an EPA-registered active ingredient (for example bifenthrin) and that the label explicitly permits indoor use and the specific pest targets

Match concentration to application

Higher-concentration formulations require different dilution rates—choose a product whose concentrate strength and mixing instructions align with your spray equipment and the infestation level

Prefer water-based or tank-mix compatibility

Water-based concentrates and those tagged for tank-mix use are easier to dilute and combine with other compatible products for professional-style applications

Consider indoor safety and odor

Look for formulations and user feedback indicating low residual odor and labels with indoor safety precautions to minimize occupant exposure during and after application

Evaluate coverage and container size

Choose a concentrate volume that matches the square footage you need to treat—larger containers like quart or gallon sizes can be more economical for whole-home treatments
