TRI-ZAP Combo: Long-Lasting Fly Control That Helps Protect Cattle Health and Performance

External parasites are more than just an annoyance for cattle. Horn flies, face flies, lice, and ear ticks can reduce weight gain, lower milk production, increase stress, and create conditions that lead to disease. For producers looking to protect their herds while maximizing productivity, choosing the right insecticide ear tag is an important part of a comprehensive pest management program.

TRI-ZAP Combo from Y-TEX was developed to provide broad-spectrum, long-lasting insect control while helping producers address one of the livestock industry's biggest challenges: insecticide resistance. By combining multiple active ingredients with different modes of action, TRI-ZAP Combo offers an advanced approach to fly control that supports healthier, more productive cattle throughout the grazing season.

What Is TRI-ZAP Combo?

TRI-ZAP Combo is a sustained-release insecticide ear tag designed for beef cattle, dairy cattle—including lactating dairy cows—and calves. The ear tag gradually releases insecticides over time, providing extended protection against some of the most common external parasites that affect cattle.

Unlike conventional ear tags that rely on a single active ingredient, TRI-ZAP Combo combines three technologies into one product:

• Zeta-cypermethrin, a fast-acting pyrethroid insecticide

• Abamectin, a macrocyclic lactone with a different mode of action

• Piperonyl butoxide (PBO), a synergist that enhances the effectiveness of the pyrethroid

This unique formulation allows TRI-ZAP Combo to provide excellent insect control while helping producers combat populations of flies that may have developed resistance to traditional pyrethroid-only products.

Why Fly Control Matters

Fly infestations affect nearly every aspect of cattle production. Horn flies alone can spend nearly their entire lives on cattle, feeding repeatedly throughout the day and causing irritation that forces animals to expend valuable energy trying to escape biting insects.

Face flies contribute to the spread of diseases such as pinkeye, while lice can cause excessive rubbing, hair loss, reduced feed efficiency, and poor body condition. Ear ticks create irritation and can damage sensitive tissue within the ear canal.

The economic impact adds up quickly. Cattle that are constantly battling parasites often experience:

• Reduced average daily gain

• Lower milk production

• Decreased feed efficiency

• Increased stress

• Greater risk of disease transmission

• Reduced overall herd performance

Effective fly control helps cattle devote more energy toward growth, reproduction, and production instead of fighting pests.

The Advantage of Multiple Modes of Action

One of the defining features of TRI-ZAP Combo is its combination of multiple insect control technologies.

Zeta-cypermethrin provides rapid knockdown of susceptible flies. Abamectin attacks insects differently than pyrethroids, helping broaden the spectrum of control while supporting resistance management efforts. Piperonyl butoxide strengthens the effectiveness of the pyrethroid by inhibiting certain insect detoxification mechanisms.

Together, these ingredients create a powerful combination that distinguishes TRI-ZAP Combo from traditional single-ingredient ear tags.

In fact, TRI-ZAP Combo is the only cattle ear tag that combines a synergized pyrethroid with a macrocyclic lactone, giving producers another valuable option when developing seasonal fly control programs.

Long-Lasting Protection Throughout Fly Season

One of the biggest advantages of insecticide ear tags is their convenience. After proper application, TRI-ZAP Combo continuously releases active ingredients over an extended period.

When used according to label directions, two tags per animal provide up to four months of horn fly control. This sustained-release technology minimizes the need for repeated handling while maintaining consistent protection during much of the grazing season.

By reducing labor and simplifying fly management, producers can spend more time focusing on herd health and overall ranch operations.

Broad-Spectrum Parasite Control

TRI-ZAP Combo is labeled to control several common cattle parasites, including horn flies, face flies, lice, and spinose ear ticks.

Because multiple pests often occur simultaneously, having one product capable of controlling several different parasites simplifies herd management and reduces the need for multiple treatment methods.

This broad-spectrum protection is particularly valuable during periods of peak insect pressure, when cattle are most vulnerable to irritation and productivity losses.

Supporting Resistance Management

Insecticide resistance has become an increasing concern across the cattle industry. Repeated use of products with the same mode of action allows surviving insects to pass resistance traits to future generations, gradually reducing product effectiveness.

TRI-ZAP Combo helps address this challenge by incorporating multiple modes of action into a single ear tag. While no product can eliminate resistance entirely, diversified chemistry can improve overall control and extend the usefulness of available insecticides.

Y-TEX also recommends rotating insecticide classes between fly seasons as part of an integrated resistance management strategy. Combining proper rotation with sound pasture management and sanitation practices helps maintain effective fly control year after year.

Easy Application with Minimal Disruption

Applying TRI-ZAP Combo is straightforward using an approved Y-TEX applicator. Once installed properly in the ear according to label instructions, the tags begin delivering continuous insecticide release.

The product is approved for:

• Beef cattle

• Dairy cattle

• Lactating dairy cows

• Calves

Because there are no meat or milk withdrawal periods when used according to label directions, producers can integrate TRI-ZAP Combo into their herd management program without disrupting production schedules.

Why Producers Choose TRI-ZAP Combo

Livestock producers need fly control products that deliver consistent performance without creating unnecessary labor or complexity. TRI-ZAP Combo offers several advantages that make it a popular choice for commercial cattle operations.

Its unique combination of insecticides provides broad-spectrum parasite control while supporting resistance management efforts. Sustained-release technology delivers protection over an extended period, reducing the need for repeated applications. The product is suitable for both beef and dairy operations, including lactating cows, making it versatile for many different production systems.

Perhaps most importantly, TRI-ZAP Combo helps improve cattle comfort. Animals that spend less time fighting biting insects can devote more energy to grazing, growth, reproduction, and milk production.

Protect Your Herd with TRI-ZAP Combo

Effective fly control is an investment in cattle health, productivity, and profitability. By combining a synergized pyrethroid, a macrocyclic lactone, and advanced sustained-release technology, TRI-ZAP Combo provides producers with an innovative solution for controlling horn flies, face flies, lice, and ear ticks throughout the grazing season.

Whether you manage a small family herd or a large commercial cattle operation, TRI-ZAP Combo offers reliable, convenient protection that helps keep cattle comfortable while supporting overall herd performance. When incorporated into a comprehensive pest management program that includes insecticide rotation and good management practices, TRI-ZAP Combo can play an important role in protecting your investment and maximizing productivity year after year.
