Farnam Equi-Spot: Long-Lasting Spot-On Fly Control

Farnam Equi-Spot provides targeted protection for horses when daily sprays aren’t feasible. The spot-on formulation offers prolonged activity, helping to keep insects away for up to two weeks. It is designed to work in pasture environments, guarding against flies that can irritate horses during turnout. The product also contributes to broader management by reducing ticks that may transmit Lyme disease when reapplied on a biweekly schedule, and it helps curb mosquitoes and other pests that can carry disease.
Key considerations include ease of application, duration, and compatibility with routine care. For pastured settings, Equi-Spot can minimize daily spray needs while maintaining effective bite deterrence. Always follow label directions for dosage, reapplication intervals, and safety precautions for horses and handlers.
Elanco Cylence Ultra Ear Tags

Elanco Cylence Ultra Ear Tags offer a multi-species pest-control approach, primarily designed for cattle but often discussed in broader pest-control contexts. These ear tags aim to provide sustained protection against common flies and ticks for several months, leveraging a synergized insecticide for persistent activity. While useful in mixed herds or on farms with cattle, horse owners should verify suitability and label guidance before deployment on equine populations. Duration guidance indicates protection extending for months, reducing the frequency of handling for fly control.
Farnam Repel-X Insecticide & Repellent

Repel-X is a versatile, water-based fly spray designed to kill and repel a broad range of flying pests. It targets six common fly species—including stable, horse, face, deer, house, and horn flies—while also addressing mosquitoes, gnats, ticks, fleas, chiggers, and lice. The formula emphasizes a balance of protection and ease of use, with a spray-on application suitable for horses, dogs, and premises. This multi-purpose option can be a practical choice for those seeking a single product to cover multiple pests across various environments without heavy residues.
Formula 707 MultiFly Pellets

Formula 707 offers a feed-through fly control option that integrates into daily horse feeding routines. The pellets contain Novaluron, an insect growth regulator that disrupts the fly life cycle, reducing the overall fly population over time. The product is positioned as safe for horses and non-organophosphate, addressing concerns about harsh chemicals. Palatability is emphasized, encouraging consistent intake as part of regular feed—making it a convenient choice for barn managers seeking long-term population management with minimal handling.
Farnam Endure Sweat-Resistant Fly Spray

Endure is a sweat-resistant fly spray designed to withstand heavy moisture and challenging weather. It aims to defend against flies, gnats, mosquitoes, ticks, and lice for up to 14 days, making it a strong option for horses that sweat heavily or ride in rainy climates. The product claims durable performance under wet conditions, ensuring ongoing protection during turnout, training, or competition. When using Endure, consider reapplication guidelines after sweat exposure or washing to maintain efficacy.
Farnam Swat Fly Repellent Ointment

Swat Ointment provides targeted protection for wounds and the face, delivering a medicated barrier against flies on susceptible areas. This ointment is easy to apply to affected regions and offers practical on-the-go protection for horses, ponies, and even dogs. Its compact 7-ounce jar makes it convenient to carry during travel or outdoor work, ensuring readiness for encounters with biting insects in areas with limited access to sprays.
Buying Guide: Choosing The Right Fly Control For Horses

Key purchase considerations include the type of control (spot-on, spray, ear tags, or feed-through), duration of protection, and ease of use. For pastured horses, spot-on products like Equi-Spot provide convenient coverage during grazing periods, while spray products such as Repel-X can deliver broad-spectrum protection with flexible reapplication. Feed-through options like Formula 707 address the fly life cycle at the source but require routine inclusion in feed and careful attention to palatability and safety. For weather-prone environments, Endure’s sweat resistance offers resilient protection against rain and humidity. Always match product selection to the horse’s environment, management style, and any health considerations. Consider combining a primary control method with supplemental measures like stall fans, physical barriers, and pasture management to maximize effectiveness. When in doubt, consult a veterinarian or equine pest-management professional for tailored recommendations.
Additional notes: Always read and follow label directions for dosage, application intervals, and safety instructions. Some products are designed for multiple species, and not all are appropriate for every animal. Consider the lifetime protection plan for a stable or farm—using a combination of spot-on, spray, ear-tags, and feed-through approaches can provide layered defense against a broad range of biting insects.
