Buying Guide

Choose the right formulation

Feed‑thru pellets work systemically to disrupt fly development, while topical sprays and sprayers provide immediate surface protection — pick based on whether you need barnwide control or individual horse coverage

Check active ingredients

Look for proven actives like novaluron in feed‑thrus or pyrethrins/permethrin in sprays; ingredients determine mode of action, residual duration, and suitability around foals or lactating mares

Consider application frequency

Feed‑thru products are typically added to daily feed, offering ongoing control, whereas sprays often require reapplication after heavy sweating or rain

Assess safety and pet‑friendly labeling

Review product labels for horse‑specific approvals, pet‑safe claims, and any cautions about skin contact or inhalation to protect handlers and animals

Match product to environment

For turnout and open pastures, systemic or long‑lasting sprays are practical; for stalls and concentrated fly pressure, whole‑barn sprayers and oil‑based formulations can provide broader control
