1. Understanding the Fly Threat to Cattle
Flies are more than just a nuisance to cattle; they pose a significant threat to their health and productivity. Understanding the types of flies that affect cattle, their life cycles, and the economic impact they have is crucial for effective control.
1.1. Common Fly Species Affecting Cattle
Three primary fly species economically impact grazing cattle: horn flies, face flies, and stable flies.
- Horn Flies: Small flies (approximately 3/16” in length) typically found on the backs, sides, and poll area of cattle. Both males and females feed on blood more than 30 times per day.
- Face Flies: Slightly larger and darker than house flies, these non-biting flies feed on animal secretions, nectar, and dung liquids. They cluster around the eyes, mouth, and muzzle, causing extreme annoyance.
- Stable Flies: Serious pests that feed on blood, primarily on the front legs of cattle. Their bites are painful, causing cattle to stomp their legs, bunch together, or stand in water to avoid being bitten.
1.2. Fly Life Cycles and Breeding Habits
Understanding the life cycles and breeding habits of these flies is essential for targeting control measures effectively.
- Horn Flies: Female flies lay eggs in fresh cattle manure. Eggs hatch within one week, and larvae feed and mature in the manure, pupating in the soil beneath. The entire life cycle can be completed in 10 to 20 days.
- Face Flies: Female face flies lay eggs in fresh manure. Larvae develop in the manure, and adults emerge to feed on animal secretions.
- Stable Flies: Female stable flies lay eggs in spoiled or fermenting organic matter mixed with animal manure, soil, and moisture. Common breeding sites include feedlots, dairy lots, and areas around feed bunks. The life cycle can take 14-24 days.
1.3. Economic Impact of Flies on Cattle Operations
The economic losses associated with fly infestations can be substantial.
- Horn Flies: Estimated to cause more than $1 billion in losses annually in the United States due to irritation, blood loss, decreased grazing efficacy, reduced weight gains, and diminished milk production. Studies have shown calf weaning weights can be negatively impacted from 4 – 15 percent. Research conducted in Nebraska indicated calf weaning weights were 10-20 pounds higher when horn flies were controlled on mother cows.
- Stable Flies: University of Nebraska research recorded a reduction in average daily gain of 0.44 lbs. per head in animals that received no insecticide treatment compared to treated animals.
1.4. Key Challenges in Fly Control
Several factors make fly control challenging:
- Insecticide Resistance: Many fly populations exhibit resistance to certain classes of insecticides, requiring rotation of insecticide classes to maintain control.
- Fly Migration: Flies can migrate from neighboring untreated herds, masking the effectiveness of control measures.
- Off-Animal Time: Face flies spend a significant amount of time off the animal, making them difficult to target with traditional control methods.
- Breeding Site Management: Stable flies breed in various organic materials, making sanitation and clean-up essential but often difficult to achieve.
2. Comprehensive Fly Control Strategies for Cattle
Effective fly control requires a multi-faceted approach that combines various strategies to target different stages of the fly life cycle.
2.1. Insecticide Application Methods
Insecticides are a primary tool for managing fly populations on cattle. Several application methods are available, each with its advantages and limitations.
2.1.1. Backrubbers and Dust Bags
Backrubbers and dust bags are effective if cattle are forced to use them regularly. These devices allow cattle to self-treat, reducing fly numbers as they rub against the insecticide-treated surfaces.
2.1.2. Insecticide Ear Tags and Strips
Insecticide ear tags and strips are a convenient method of horn fly control. However, resistance to pyrethroid insecticides is common. Rotating insecticide classes is crucial to maintain effectiveness.
2.1.3. Animal Sprays and Pour-On Products
Animal sprays and pour-on products provide short-term control (7-21 days) and require reapplication throughout the fly season.
2.1.4. Oral Larvicides
Oral larvicides prevent fly larvae from developing into adults. Consistent consumption is essential for effectiveness, and migration from untreated herds can complicate results.
2.1.5. Vet Gun™
The Vet Gun™ applies individual capsules of insecticide to an animal and can provide control between 21 and 35 days.
2.2. Non-Chemical Control Methods
Non-chemical control methods can reduce reliance on insecticides and provide a more sustainable approach to fly management.
2.2.1. Pasture Management
Proper pasture management can help reduce fly breeding sites and minimize fly populations.
- Rotational Grazing: Moving cattle to different pastures can break the fly life cycle by reducing manure accumulation in one area.
- Manure Management: Regularly dragging or harrowing pastures can help break up manure pats and expose fly larvae to predators and sunlight.
- Vegetation Control: Cutting or mowing vegetation around pastures can reduce shaded areas where flies congregate.
2.2.2. Biological Control
Biological control involves using natural enemies of flies to reduce their populations.
- Dung Beetles: Dung beetles bury and consume manure, disrupting fly breeding sites.
- Parasitic Wasps: Parasitic wasps lay their eggs in fly pupae, killing the developing flies.
- Predatory Flies: Certain fly species prey on other flies, helping to control their populations.
2.2.3. Sanitation and Environmental Management
Sanitation and environmental management are crucial for controlling stable flies and other manure-breeding flies.
- Feedlot and Dairy Lot Clean-Up: Regularly remove spoiled feed, manure, and other organic materials from feedlots and dairy lots.
- Winter Feeding Site Management: Clean up wasted feed at winter feeding sites to reduce larval development.
- Compost Management: Properly manage compost piles to minimize fly breeding sites.
2.3. Integrated Pest Management (IPM) Strategies
Integrated Pest Management (IPM) is a comprehensive approach that combines multiple control methods to achieve long-term fly management. An IPM program typically includes:
- Monitoring: Regularly monitor fly populations to determine when control measures are needed.
- Thresholds: Establish economic injury levels (EIL) to guide treatment decisions. For example, the EIL for horn flies is 200 flies per animal, and the economic threshold for stable flies is 5 flies per leg.
- Cultural Practices: Implement pasture management and sanitation practices to reduce fly breeding sites.
- Biological Control: Utilize natural enemies of flies to reduce their populations.
- Chemical Control: Use insecticides judiciously, rotating insecticide classes to prevent resistance.
3. Targeted Fly Control for Specific Fly Species
While some control methods are effective against multiple fly species, others are more targeted. Understanding the specific characteristics of each fly species allows for more effective control.
3.1. Horn Fly Control Strategies
Horn flies are particularly susceptible to certain control methods due to their close association with cattle.
- Insecticide Ear Tags: Effective for horn fly control, but rotation of insecticide classes is essential to prevent resistance.
- Backrubbers and Dust Bags: Ensure cattle use these devices regularly to maximize effectiveness.
- Oral Larvicides: Can be effective if consumption is consistent and migration from untreated herds is minimal.
3.2. Face Fly Control Strategies
Face flies are more challenging to control due to their habit of feeding around the face and spending time off the animal.
- Dust Bags and Oilers: Daily insecticide applications can help control face flies.
- Insecticide Ear Tags/Strips: Apply at the label-recommended rate to both cows and calves.
- Pinkeye Vaccines: Consider using pinkeye vaccines if face flies and pinkeye are recurring problems. According to the American Veterinary Medical Association, vaccination is a key preventative measure.
3.3. Stable Fly Control Strategies
Stable flies breed in organic matter, making sanitation and environmental management critical.
- Sanitation: Remove spoiled feed, manure, and other organic materials from breeding sites.
- Animal Sprays: Weekly applications of animal sprays can reduce fly numbers.
- Larvicides: Apply larvicides to breeding sites where sanitation is not possible.
