If you use a cattle oiler for fly and pest control, one of the most important questions is also one of the simplest: what do you put in it?

A cattle oiler is an application device. The liquid placed in the tank or reservoir must be appropriate for the cattle, the pests being controlled, and the method of application. Depending on the product, a treatment may be supplied ready to use or may require mixing with an approved carrier before it is added to the oiler.

Always follow the treatment manufacturer's current label rather than relying on a general mixing formula. The label determines whether a product can be used on cattle, whether it is suitable for a self-treatment device such as an oiler or backrubber, how it should be mixed, and what safety precautions apply.

If you're also selecting the equipment itself, Barn World offers cattle oilers and cow brushes for different livestock setups and traffic patterns.

What Do You Put in a Cattle Oiler?

Cattle oilers are commonly used to apply livestock pest-control treatments as cattle rub against a brush, mop, apron, or other treated surface. The appropriate liquid depends on the particular pest-control product and the instructions on its label.

Before putting any treatment into an oiler, confirm that the label permits its use:

• On cattle
• For the pest you are trying to control
• With the intended application method
• At the specified concentration or dilution
• For the class of cattle being treated

Do not assume that an insecticide labeled for cattle can automatically be used in a cattle oiler. Livestock pest-control products can have different approved application methods, so the label should specifically support the way you intend to use the treatment.

Cattle Oiler Insecticides

Many cattle oilers are designed to dispense an insecticide or other livestock pest-control treatment. These products may be labeled for external parasites such as certain flies, lice, or ticks, depending on the particular formulation.

The active ingredient is the component responsible for controlling the targeted pest. Different livestock insecticides use different active ingredients and work in different ways. Rather than selecting a product based only on the name of an active ingredient, look at the entire product label to determine whether it is appropriate for your cattle and oiler.

The label should identify the target pests, application method, mixing directions when applicable, precautions, and other restrictions.

What Is the Oil in a Cattle Oiler?

The word "oiler" can make it sound as though any type of oil can simply be poured into the equipment. That isn't the case.

Some pest-control products are formulated to be used with a particular carrier or diluent. Others may be supplied as ready-to-use formulations. What should be used depends on the specific product.

Do not substitute mineral oil, diesel fuel, vegetable oil, water, or another carrier simply because it seems suitable for the equipment. Use only the carrier and mixing method specified by the treatment manufacturer.

This is especially important because the carrier can affect how the treatment moves through the oiler, coats the applicator, and reaches the animal.

Ready-to-Use vs. Concentrated Treatments

Livestock pest-control products can come in different formulations. Some are ready to use, while others are concentrates that require preparation according to their labels.

Ready-to-Use Products

A ready-to-use product is supplied at its intended application concentration and generally does not require the user to calculate a dilution. That does not necessarily mean it is appropriate for every cattle oiler. The label still needs to permit the intended application method.

Concentrated Products

Concentrated treatments require additional care. The label provides the proper mixing instructions, approved carrier, application rate, and safety requirements.

A stronger mixture is not automatically more effective and may violate label directions or create unnecessary exposure. Likewise, an overly diluted mixture may not provide the intended pest control. Follow the labeled concentration rather than estimating a mixture.

Match the Treatment to the Pest

Before choosing what to put in a cattle oiler, identify the pest you're trying to manage. A treatment labeled for one pest should not automatically be assumed to control another.

Common external pests affecting cattle can include:

• Horn flies
• Face flies
• Stable flies
• Lice
• Ticks

The pests present can vary by location and season. Check the treatment label to see which pests it is intended to control and whether a cattle oiler, backrubber, or similar self-treatment device is an approved application method.

How the Treatment Gets onto the Cattle

The cattle oiler itself doesn't create the pest-control treatment. Its job is to transfer the liquid from a reservoir or treated applicator onto the animal.

Different equipment handles that transfer differently. Brush oilers allow cattle to rub against treated bristles. Mop oilers use absorbent material suspended where cattle pass underneath. Apron oilers use hanging material that contacts the animal as it moves through an alley or other controlled area.

For a closer look at these designs, see our guide to types of cattle oilers.

The condition of the applicator matters. A worn brush, dried mop, damaged apron, clogged fitting, or poorly adjusted flow system can interfere with treatment distribution even when the correct liquid is in the reservoir.

Don't Guess at Cattle Oiler Mixing Ratios

There is no single cattle oiler mixing ratio that applies to every insecticide or pest-control product.

Mixing requirements depend on the formulation. If a product requires dilution, use the exact directions provided on its current label. Pay attention to the specified carrier, concentration, application method, and any restrictions that apply to the cattle being treated.

This is also why an old mixing recommendation shouldn't automatically be applied to a product being used today. Formulations, labels, and approved uses can change.

Check Your Oiler While It Is in Use

Choosing the right treatment is only part of using a cattle oiler effectively. The equipment also needs regular inspection.

During pest season, check:

• Treatment level in the reservoir
• Brushes, mops, or aprons for wear
• Hoses and fittings for leaks
• Valves and flow-control components
• Whether the applicator is receiving treatment
• Whether cattle are actually using the oiler

If the tank remains full for an unusually long time, don't automatically assume the treatment is lasting longer. Check whether cattle are using the equipment and whether the liquid is reaching the application surface correctly.

Replacement cattle oiler parts can help keep existing equipment operating when brushes, mops, springs, valves, hoses, and other components become worn or damaged.

Placement Also Affects Treatment Application

Even the correct treatment won't accomplish much if cattle rarely contact the oiler. Place the equipment where cattle naturally travel or congregate, such as near gates, feeding areas, mineral locations, watering areas, or frequently used alleys when appropriate for the particular installation.

The equipment should be mounted securely and positioned so cattle make appropriate contact with the applicator. Our cattle oiler installation guide covers placement, mounting, and initial setup in more detail.

Handling Cattle Oiler Treatments Safely

Livestock insecticides and other pest-control products should be handled according to their labels. Follow requirements for personal protective equipment, mixing, storage, disposal, and animal use.

Keep treatment containers properly labeled, and don't transfer chemicals into an unlabeled container. Store products as directed and keep them away from children, pets, feed, and other materials when required by the label.

If you are uncertain whether a treatment is appropriate for your cattle, pest problem, or application equipment, consult the product manufacturer, your veterinarian, or another qualified livestock pest-management professional before using it.

Frequently Asked Questions

Can I put any cattle insecticide in a cattle oiler?

No. Use a product only when its label permits use on cattle and supports the intended application method. A product approved for another type of livestock application should not automatically be used in an oiler.

Can I use mineral oil in a cattle oiler?

Only use mineral oil as a carrier when the particular pest-control product's label specifies or permits it for that use. Do not assume that mineral oil is appropriate for every cattle oiler treatment.

How much insecticide should I put in a cattle oiler?

Follow the treatment label. There is no universal amount or mixing ratio because products, concentrations, carriers, application methods, and oiler capacities vary.

Can I make my own cattle oiler treatment?

A homemade mixture should not replace the directions for a registered livestock pest-control product. If you're using an insecticide or pesticide, follow its label for approved animals, pests, application methods, concentrations, and carriers.

How often should I refill a cattle oiler?

There is no single refill schedule for every operation. Check the reservoir regularly and consider herd size, frequency of use, oiler capacity, equipment condition, and the directions for the treatment being used.
