Why Old-Timers Trust Oilers for Lice Control

Livestock oilers work on a simple, brilliant principle: animals treat themselves. When an animal feels an itch from lice, its first instinct is to rub. By placing an oiler in their path, you turn that natural behavior into an effective pest control method.

This self-service approach is far less stressful than running the whole herd through a chute for treatment. There’s no roundup, no shouting, and no panic. The animals apply the treatment exactly where they need it, when they need it, ensuring consistent protection without you having to lift a finger after the initial setup. These things are built to last, often outliving the farmers who install them.

Lewis Cattle Oiler: The Classic Walk-Through

The Lewis Cattle Oiler is the gold standard for a reason. It’s a free-standing arch with hanging, oil-saturated mops that you place in a high-traffic lane, like the path to the water trough or a mineral feeder. To get to what they want, cattle must walk through it, ensuring every single animal gets a dose.

This forced-use design is its greatest strength. You get guaranteed, full-body coverage on the entire herd, which is crucial for breaking the lice life cycle. The downside is the cost and the need for a specific layout to funnel your animals through it. It’s a serious investment, but for a set-and-forget system, it’s unmatched.

Sioux Steel Mineral Feeder: Feed and Treat

Combining a mineral program with pest control is a smart move. The Sioux Steel Mineral Feeder with a face fly attachment does just that. It features oil-soaked wicks or flaps hanging around the hood where animals access the loose mineral.

As cattle and other livestock stick their heads in to eat, they rub their face, neck, and shoulders against the wicks. This is perfect for targeting face flies and the lice that congregate around the head and topline. It won’t provide the full-body coverage of a walk-through oiler, but it’s an incredibly efficient way to treat problem areas while accomplishing another essential chore.

Priefert Post-Mounted Oiler: Simple and Tough

Sometimes the simplest solution is the best one. The Priefert Post-Mounted Oiler is a vertical reservoir with a canvas wick that you bolt to a sturdy post or tree. It’s tough as nails, relatively inexpensive, and can be placed anywhere your animals tend to gather and loaf around.

This type of oiler is an "invitation" rather than a requirement. Animals will use it when they feel the need to scratch, making it a great addition to a pasture or dry lot. While you don’t get the guaranteed application of a walk-through, its simplicity and durability make it a fantastic, low-cost tool for giving your herd relief.

Tarter 3-Chain Oiler for Full-Body Coverage

The Tarter 3-Chain Oiler strikes a great balance between coverage and convenience. It consists of a horizontal reservoir tank with three weighted, wick-covered chains hanging down. You suspend it between two posts in a gateway or other high-traffic area.

As cattle pass underneath, the chains drape over their back and sides, providing excellent coverage along the topline where lice are most common. It’s more thorough than a simple post rubber but less restrictive and expensive than a full arch oiler. This design is a versatile workhorse for small to medium-sized herds.

Behlen Upright Wick Oiler for Goats and Sheep

Smaller livestock need solutions built for their size and habits. The Behlen Upright Wick Oiler is a shorter, more compact version of the post-mounted oilers designed for cattle. Goats and sheep are natural rubbers, and this gives them a dedicated spot to scratch that itch.

Placement is everything with these. Install it on a post they already favor for scratching, and they’ll take to it immediately. It is critical to use an insecticide and oil mixture that is approved for sheep, as some products safe for cattle can be toxic to them. Always read the label.

DIY Cable Oiler: A Frugal, Effective Option

You don’t need to spend a lot of money to get effective results. A DIY cable oiler is a classic, frugal solution that works surprisingly well. Simply string a thick steel cable between a solid post and a heavy, moveable anchor like a concrete-filled tire.

Wrap the cable tightly with burlap sacks or thick rope, securing it with wire. Then, saturate the wrapping with your chosen oil mixture using a bucket and a brush. The angled cable allows animals of all sizes to rub their back, sides, and head. It requires more frequent re-oiling than a commercial model with a reservoir, but for the cost of a cable and some burlap, you can’t beat the value.

Choosing the Right Oil and Maintaining Your Oiler

An oiler is only as good as what you put in it. Most producers mix a livestock-approved insecticide, often a permethrin-based product, with a carrier oil. Diesel fuel has been the traditional carrier, but many now prefer mineral oil for a less harsh option.

• Always read the insecticide label. It will give you the correct mixing ratio and list which animals it is safe for.
• Consider natural options. For a chemical-free approach, you can use straight mineral oil or vegetable oil mixed with essential oils like tea tree, cedarwood, or peppermint. Be aware that this may be less potent and require more frequent application.

Maintenance is simple but non-negotiable. Keep the reservoir topped off and ensure the wicks or chains are saturated. A dry oiler is just an expensive scratching post. Check it weekly during peak lice season to make sure it’s working for you.

Ultimately, livestock oilers are a testament to smart, simple design. They reduce your workload, lower animal stress, and provide continuous, effective protection against lice. The best choice depends on your herd, your pasture layout, and your budget, but any of these options will make a real difference.

Frequently Asked Questions (FAQs)

What is a livestock oiler for pest control?

A livestock oiler for pest control is a mechanical applicator that rubs a blend of carrier oil and insecticide onto livestock to repel flies, lice, and ticks. As animals scratch against the canvas, mop, or brush mechanism, a small amount of liquid transfers directly to their coat. This automated system protects cattle, sheep, or goats in pastures without requiring ranchers to corral them for routine manual spraying.

What pests do livestock oilers control on pasture cattle?

Livestock oilers control external parasites including horn flies, face flies, stable flies, biting lice, sucking lice, and ticks. Horn flies cause the most economic damage to cattle by feeding up to forty times daily, reducing weight gain and milk production. Placing an oiler near mineral feeders or water tanks delivers continuous, targeted coverage across the back, neck, and face where these pests congregate most heavily.

How do I mix insecticide solution for a cattle livestock oiler?

To mix chemical solution for a cattle livestock oiler, blend an EPA-approved oil-based insecticide with an approved carrier oil according to the product label ratio. Most manufacturers specify mixing one part concentrated insecticide, such as permethrin or phosmet, with 10 to 14 parts of food-grade mineral oil or diesel fuel. Pour the carrier oil into the tank first before adding the active chemical to prevent separation and ensure uniform dispersal across the wick.

How do you train reluctant cattle to use a livestock oiler in pasture?

Ranchers train reluctant cattle to use a livestock oiler by placing the device in high-traffic choke points like gate openings or alleys leading to water tanks. Hanging mineral blocks or salt licks directly beyond the applicator encourages curious animals to push past the rubbing curtain. If cattle avoid the machine initially, leave the tank uncharged with insecticide for three to five days until the herd touches the unit comfortably.

Which is better, a mop livestock oiler or a brush livestock oiler?

Brush livestock oilers are better for heavy pest pressure and shedding winter coats, while mop oilers excel at providing even, continuous fluid distribution on smooth-coated animals. Wire-backed nylon brushes withstand aggressive scratching from mature bulls and scrub deep dirt from the hide. In contrast, canvas or cotton mop oilers absorb fluid thoroughly and reduce chemical dripping, making them more economical for average cow-calf herds in open pastures.

How much does a commercial livestock oiler cost for a small herd?

Commercial livestock oilers cost between 250 dollars for basic gravity-fed hanging wick models and 3,500 dollars for heavy-duty, stationary pump systems. Portable pasture models with integrated mineral feeders typically range from 800 to 1,800 dollars. For a small herd under 30 head, a heavy-duty single-cable hanging oiler offers adequate coverage and keeps initial setup expenses under 400 dollars, excluding the cost of carrier oil and insecticide.

Why is my livestock oiler dripping too much chemical on the ground?

Excessive chemical dripping from a livestock oiler is usually caused by an improperly adjusted control valve, a torn wick curtain, or carrier oil that is too thin. Inspect the metering valve and tighten it clockwise by a quarter turn to restrict flow onto the wicks. If using diesel or kerosene in hot summer temperatures, switch to a heavier 10-weight or food-grade mineral oil, which resists thinning and clings better to the applicator.

Is using a livestock oiler safe for nursing calves and pregnant cows?

Using a livestock oiler is safe for pregnant cows and nursing calves provided you select an insecticide specifically labeled for all cattle classes. Certain organophosphates can harm younger calves or pass through milk, so ranchers typically select permethrin formulations labeled for lactating and breeding stock. Mount the hanging cables high enough so that calves do not rub their eyes or mouths directly against concentrated fluid saturating the lower wicks.
