Comfort First, Performance Follows.

When the summer heat sets in, cattle feel it, and so does your operation. From reduced feed intake to agitation and weight loss, hot weather and pest pressure can disrupt both beef and dairy cattle. And while things like fans and shade help, true cattle comfort starts from the inside out, beginning with what’s in their feed.

ClariFly® Larvicide is a feed-through fly control solution that targets flies where they start: in manure. By keeping fly populations in check, you reduce one of the biggest hidden stressors on your herd and create a calmer, more productive environment when it matters most.

Hot Temps + High Fly Pressure = Trouble for Cattle

Summer doesn’t just bring heat, it brings flies. And while they may seem like a minor nuisance, flies are a major stressor to cattle. This is especially true for pasture-based beef herds, where widespread manure and open exposure can lead to fast fly population growth with little visible warning. Swarming pests can lead to:

  • Increased energy spent swatting and pacing
  • Reduced grazing and feed intake
  • Lower milk production and weight gain
  • Greater risk of disease spread

ClariFly® Larvicide works behind the scenes, disrupting the development of house flies, stable flies, face flies, and horn flies, all without affecting the cattle. It’s not a knockdown product. It’s a smart, consistent way to reduce emerging fly populations before they ever become a problem.

Build a Cow Comfort Game Plan

Here’s how you can pair ClariFly® with smart management tactics to support cattle health and performance in the heat.

  1. Stay Ahead of Hydration

    Water is critical in hot weather. Make sure tanks are clean, accessible, and shaded. Monitor for proper flow, especially in remote pastures or large pens.

  2. Provide Smart Shade

    Natural tree cover, open-sided barns, or shade structures can drastically reduce heat load. Prioritize shaded areas in pastures and create “cool zones” near water sources or feed bunks.

  3. Improve Air Movement

    Ventilation is everything. Whether it’s large barn fans or improved airflow in loafing sheds, moving air helps cattle release heat. Check fan operation early in the season and keep blades clean.

  4. Shift Feeding Times

    Feed cattle early in the morning or later in the evening when temperatures are cooler. This small change can help maintain intake and reduce the impact of heat-related appetite loss.

  5. Grazing and Manure Management

    Beef cattle on pasture often move through rotational grazing systems, where manure is widely dispersed. While harder to manage manually, ClariFly® Larvicide works through the animal to target fly larvae wherever manure is deposited, offering consistent control even across large grazing areas.

The Hidden Power of Prevention

While heat stress is visible, fly pressure often builds quietly. A fly problem you see in August started weeks earlier. That’s why ClariFly® Larvicide is designed to be proactive, starting in early spring and continuing through fly season.

By preventing the development of flies in manure, ClariFly® Larvicide helps reduce the biting, swarming, and stress that chip away at herd health. When paired with solid summer comfort strategies, it’s a dynamic way to keep your cattle cool, calm, and productive.

Your cattle work hard. Give them a summer that works for them.
