6 Best Cattle Oilers For Horn Fly Prevention That Old Farmers Swear By

Imagine a mid-July afternoon where a herd spends more energy tail-flicking and head-tossing than actually grazing. Horn flies can siphon off a significant amount of blood daily from a single animal, leading to measurable weight loss and decreased milk production in even the hardiest breeds. Implementing a self-treatment system like a cattle oiler turns a persistent seasonal nuisance into a passive management win for any small-scale producer.

Lewis Single-Station Cattle Oiler: The Gold Standard

The Lewis Single-Station Cattle Oiler is widely regarded as the pinnacle of fly control technology because of its precision-engineered pump system. Unlike gravity-fed models that can leak or dry up, this unit uses a mechanical pump activated by the animal’s movement to deliver a fresh dose of insecticide to the wick. This ensures that the chemical remains potent and is only dispensed when a cow is actively using the machine.

Durability is the hallmark of this particular system, featuring a heavy-duty steel reservoir and a rugged, oversized wick that can withstand years of rubbing from the most aggressive cattle. The large capacity tank reduces the frequency of refills, which is a major benefit for hobby farmers who cannot check their pastures every single day. It is designed to handle everything from calves to mature bulls without skipping a beat.

You should choose the Lewis Oiler if you are looking for a “buy once, cry once” solution that offers the most consistent chemical delivery on the market. While the initial investment is higher than other options, the reduction in wasted insecticide and the longevity of the hardware make it the most cost-effective choice for a permanent operation. This is the definitive choice for the serious producer who values mechanical reliability over all else.

Behlen Country Wick Cattle Oiler: Best for Budgets

The Behlen Country Wick Cattle Oiler offers a straightforward, effective design that prioritizes simplicity and affordability. It typically consists of a high-capacity tank that feeds a heavy-duty mop or wick via gravity, allowing the animal to apply the solution simply by walking under or rubbing against it. Because it lacks complex moving parts, there is very little that can break or malfunction during a busy grazing season.

For the hobby farmer managing a small group of five to ten head, this unit provides an excellent entry point into automated fly control. It is lightweight enough to be moved between paddocks if you practice rotational grazing, yet sturdy enough to stay put when properly anchored. The replacement wicks are inexpensive and widely available, making long-term maintenance a breeze.

If you are just starting out or need to outfit multiple smaller lots without breaking the bank, this is the unit for you. It performs its primary job with zero fuss and requires very little technical knowledge to set up or maintain. The Behlen Country Wick is the ideal solution for the budget-conscious farmer who needs a reliable, no-frills tool for immediate relief.

Totem Ultimate Touch Cattle Oiler: Heavy-Duty Pick

The Totem Ultimate Touch is built for environments where equipment takes a beating, featuring a vertical design that encourages cattle to groom their faces and shoulders. It utilizes a series of brushes and a sturdy internal reservoir that dispenses oil through the bristles as the cattle scratch. This vertical orientation is particularly effective at reaching the poll and neck areas where horn flies like to congregate away from the tail’s reach.

The heavy-duty base and galvanized steel components ensure that even a thousand-pound steer cannot easily tip or damage the unit. This model is especially useful for those with horned cattle, as the brush system is less likely to snag or tear compared to traditional rope wicks. It provides a tactile satisfaction for the animal that encourages frequent use, ensuring a high rate of treatment across the entire herd.

This is the machine you want if your cattle are notoriously hard on equipment or if you have a mix of sizes and breeds in one pen. The “ultimate touch” refers to the grooming benefit, which helps remove winter hair while simultaneously applying fly protection. Choose the Totem if you need a tank-like build and a system that doubles as a high-intensity grooming station.

E-Z Brush and Oiler System: Best Dual-Purpose Unit

The E-Z Brush and Oiler System bridges the gap between a simple scratcher and a sophisticated medicator. It features a rugged brush assembly that holds the insecticide within the bristles, allowing for deep penetration into the animal’s coat. The action of the brush helps work the oil down to the skin, which is essential for killing flies that have already latched on.

One of the standout features of this system is its versatility in mounting; it can be fixed to a post, a wall, or a dedicated stand depending on your pasture layout. The brush material is specifically designed to be resistant to UV damage and the corrosive effects of certain oil-based chemicals. This ensures the bristles remain stiff and effective even after several seasons of exposure to the elements.

This unit is perfect for the hobbyist who wants to see their cattle looking sleek and well-groomed while staying fly-free. It is particularly effective for gentler herds or dairy crosses that appreciate the grooming aspect as much as the fly relief. Invest in the E-Z Brush system if you want a versatile, mount-anywhere solution that keeps your cattle’s coats in show-ready condition.

Peet’s Double Spring Cattle Oiler: Built to Last

Peet’s Double Spring Cattle Oiler is a classic design that has remained a favorite for decades due to its unique tensioning system. The use of two heavy-duty springs allows the oiling cable to give and take as the animal moves through it, preventing the wire from snapping under extreme pressure. This flexibility ensures that the cable can wrap around the animal’s body, providing much better coverage than a rigid system.

The “wrap-around” effect is the secret to this oiler’s success, as it applies insecticide to the flanks and belly—areas often missed by top-down dispensers. The reservoir is typically mounted high, keeping the bulk of the chemical safe from curious calves while using gravity to keep the cable saturated. It is a simple, effective mechanical design that leverages physics to ensure the cattle do the work for you.

If your pasture setup involves narrow alleyways or specific “choke points” where cattle pass through daily, this spring-loaded system is unbeatable. It is tough enough for the back-forty but precise enough to avoid wasting expensive chemicals. This is the best choice for those who want maximum body coverage and a design that can survive decades of use.

Tatge Cattle Oiler with Spring: Best for Bull Pens

The Tatge Cattle Oiler is specifically engineered to handle the sheer force of large-framed cattle and aggressive bulls. It utilizes a heavy-duty spring-loaded arm that returns to its original position after every use, maintaining the integrity of the station regardless of how hard it is pushed. The wick is thick and absorbent, designed to hold a significant amount of oil to minimize “dry” periods between refills.

Bulls often destroy standard oilers by leaning their full weight against the frame, but the Tatge design accounts for this with a reinforced pivot point. The simplicity of the gravity-drip onto a protected wick means there are no small valves or pumps to clog with dust or hair. It is a workhorse in every sense of the word, providing a stable target for cattle seeking relief.

You should opt for the Tatge if you are managing a breeding bull or large steers that have a history of breaking lighter equipment. It provides the peace of mind that the oiler will still be standing and functional when you return to the pasture. The Tatge is the premier “bull-proof” option for those who prioritize structural integrity and massive durability.

Where to Position Your Oiler for Maximum Daily Use

The most effective oiler in the world is useless if the cattle do not interact with it regularly. To ensure success, you must place the unit in a “force-flow” area where the herd is naturally inclined to congregate or pass through. Gateway openings between paddocks or the path leading to the water tank are the two best locations for consistent results.

Avoid placing oilers in low-lying areas that become mud holes when the cattle congregate around the machine. Instead, select a well-drained, high-traffic spot or consider pouring a small concrete pad or laying down heavy gravel to keep the area stable. If the ground becomes a swamp, the cattle will eventually avoid the oiler to stay on solid footing.

Consider the height of the oiler in relation to the average size of your herd, especially if you have a mix of cows and calves. An oiler set too high will miss the calves entirely, while one set too low might be stepped on or damaged by mature bulls. Using a “drape” style wick that hangs low enough for calves to walk under ensures the entire herd receives protection.

Choosing and Mixing the Right Oil-Based Insecticide

When selecting a chemical for your oiler, always choose an oil-based insecticide specifically labeled for use in back-rubbers. These formulations are designed to resist evaporation and rain-washout much better than water-based sprays. Most old-timers recommend a mix of a concentrated insecticide (like Permethrin) with a carrier oil to help it spread across the hide.

While diesel fuel was once the standard carrier oil, many modern farmers prefer food-grade mineral oil because it is gentler on the animal’s skin and lacks the harsh odor. Mineral oil is also less likely to cause irritation or hair loss on sensitive animals during the heat of the summer. Always follow the mixing ratios on the insecticide label precisely; more is not better and can lead to chemical burns.

Be mindful of the “withdrawal period” for any chemical you choose, especially if you plan to slaughter an animal for beef or are milking for consumption. Keep a simple log of when the oiler was last filled and what chemical was used to ensure safety. Using a high-quality carrier oil ensures the insecticide stays active longer and provides a better return on your investment.

Routine Maintenance to Keep Your Cattle Oiler Working

Maintenance on a cattle oiler is generally minimal but absolutely critical for the health of your herd. At least once a week, check the reservoir levels and ensure the wick or brushes are still saturated and pliable. If a wick becomes “glazed” with a thick layer of mud and hair, it will no longer dispense oil effectively and needs to be scraped or cleaned.

Check all mounting hardware, springs, and cables for signs of wear or fatigue caused by the constant movement of the cattle. A snapped cable or a loose bolt can turn a helpful tool into a safety hazard that could cause injury to an animal. Keeping the moving parts lubricated—ironically, often with the same oil used for the flies—prevents the metal-on-metal squeaking that can deter some cattle.

At the end of the fly season, it is a good practice to empty the reservoir and give the unit a thorough cleaning before winter sets in. This prevents the oil from thickening into a sludge that will be difficult to clear out the following spring. Consistent maintenance ensures that the oiler is ready to go the moment the first fly appears in the spring.

Training Reluctant Cattle to Use a New Oiler System

Cattle are creatures of habit and can sometimes be suspicious of a new piece of equipment placed in their environment. To encourage them to use a new oiler, try placing a mineral block or a small amount of “treat” feed directly on the other side of the unit. This forces them to brush against the wick to reach the reward, teaching them that the machine is not a threat.

If you have a particularly skittish herd, you can leave the oiler in the pasture for a few days without any insecticide in it so they can get used to its scent and shape. Once they are comfortable scratching on it, fill the reservoir and let the chemical do its work. Often, once the “lead cow” discovers the relief the oiler provides, the rest of the herd will quickly follow her example.

Persistence is key when introducing new technology to a small-scale farm. If the cattle are not using the oiler after a week, reconsider its placement or the height of the wicks. Sometimes moving the unit just ten feet closer to a shade tree can make all the difference in daily engagement. Patience and strategic placement will eventually turn the oiler into the most popular spot in the pasture.

Effective fly control is not about constant intervention; it is about setting up a system that works while you are busy with other farm chores. By choosing the right oiler for your herd size and temperament, you provide your cattle with the comfort they need to stay healthy and productive all summer long.
