Cutting Horse Care Costs: Supplements and Fly Control

July 22, 2026 ยท 6 min read

Anyone who has owned a horse for more than a season knows the recurring costs add up faster than the big, one-time ones. Board, farrier visits, and vet care get most of the attention in budgeting conversations, but supplements and fly control are the quiet expenses that show up every single month, year-round in most climates. Because they are recurring, they are also where a little bit of smarter buying compounds into real savings.

Supplements: Buy Bigger, Buy Smarter

Joint support, hoof supplements, digestive aids, and coat supplements are usually sold in a range of container sizes, and the cost per scoop or per day drops noticeably as the container gets larger. If your horse is on a supplement long-term โ€” which is common for joint and digestive support โ€” buying the largest size you can store properly is almost always the better deal on a per-day basis. The catch is that pricing on the same product can vary a surprising amount between tack shops, farm supply stores, and online retailers, so the size discount only pays off fully if you are also buying from the retailer with the best base price.

Fly Control Is a Seasonal Budget Line, Not a One-Off Purchase

Fly predators, sprays, wipe-ons, feed-through control, and fly sheets all serve different parts of a fly control program, and most serious horse owners end up using several of them together through fly season. Because this is a seasonal but recurring cost, it is worth planning the purchase the same way you would plan hay for the winter โ€” buying key items before the season peaks and prices with it, rather than restocking mid-season when supply tightens and prices tend to climb.

Concentrate Versus Ready-to-Use

Fly sprays in particular come in both ready-to-use and concentrate form. Concentrate is almost always cheaper per gallon once mixed, sometimes dramatically so, but it requires proper dilution and a spray bottle you are willing to maintain. For a single-horse barn the convenience of ready-to-use may be worth the premium; for anyone managing multiple horses, switching to concentrate is one of the more straightforward ways to cut the fly control budget without changing products.

Price-Match Before You Reorder

Feed and tack store pricing on both supplements and fly control products shifts with promotions, seasonal demand, and each retailer's own stocking decisions. A supplement that was cheapest at one store last spring is not guaranteed to be cheapest there again this fall. Checking prices across retailers before reordering โ€” rather than defaulting to whichever barn or online store you used last time โ€” is the single habit that saves the most money over a full year of ownership.

Watch for Multi-Horse and Subscription Discounts

If you keep more than one horse, or you know you will reorder the same supplement on a predictable schedule, look specifically for multi-buy pricing and subscribe-and-save options. These discounts are often modest on any single order โ€” five or ten percent โ€” but because supplements and fly control are ongoing costs, that percentage compounds into real money across a full year.

Don't Compromise on the Wrong Line Item

As with any cost-cutting effort, the goal is to pay less for the same level of care, not to reduce the care itself. Skipping fly control during peak season or cutting a joint supplement short to save money tends to cost more later, in vet bills or in your horse's comfort. The reliable savings come from where and how you buy, not from doing less.

The Bottom Line

Horse care costs are dominated by recurring items like supplements and fly control, which also means they are the items most worth comparison shopping. Buying larger sizes when it makes sense, timing seasonal purchases early, and checking prices across retailers before every reorder can trim a meaningful amount off the annual bill โ€” and that comparison is exactly what PetSaver is designed to handle for you.
