Buying Guide

Choose by application method

Select sprays for quick topical coverage, wipe-and-spray for targeted areas, and feed-through pellets for continuous internal control

Check active ingredients

Look for EPA-registered insecticides or proven botanical actives and match them to the pests you need to control, such as biting flies or stable flies

Consider horse and tack safety

Prefer formulas labeled safe for leather and common grooming materials, and avoid products that warn against contact with sensitive skin

Evaluate duration and reapplication

Note how long protection lasts per application and whether the product is intended for daily, weekly, or continuous use through feed

Factor in barn and premise use

If you need barn or stall treatment as well as on-horse protection, pick a product labeled for premises or dual use
