The best fly control for cattle depends on which fly is causing the problem. Horn and face flies are managed mainly on or through cattle; stable flies often require cleaning up the material where they breed around facilities. First identify the pest, then choose a control method that fits its habits, your herd routine, and the current product label.
Identify the fly before choosing a treatment
Different flies feed and develop in different places, so a product that helps against flies on cattle may do little for flies breeding near a barn or feeding area. Horn flies and face flies are primarily addressed on the animal or through treatments the herd consumes. Stable-fly management also depends on removing suitable breeding material around facilities. The University of Minnesota Extension guide to managing flies on cattle farms distinguishes animal treatments from premise management.
- Horn flies: focus on control on cattle, using a method suited to the herd and monitoring fly numbers.
- Face flies: because they feed on the face and spend time off the animal, forced-use devices and other targeted approaches may be more practical than relying on a spray alone.
- Stable flies and other premise flies: inspect areas around barns, feeders, and waterers for manure, old feed, and other decaying organic matter.
If flies persist despite treatment, check that you have identified the right species before changing products or increasing application frequency.
Compare cattle fly-control options
| Method | Best fit | Practical considerations |
|---|---|---|
| Dust bags | Self-treatment for horn or face flies | Place where cattle are made to pass through. Inspect and recharge as needed, and keep the bags dry. Arkansas Extension describes close-mesh bags that hold insecticide dust in its guide to treating cattle for face flies. |
| Back rubbers or oilers | Self-treatment for cattle routed through a gateway | Face-flip cloths can increase contact around the face. Follow the current pesticide label for permitted mixtures and application. |
| Insecticide ear tags | Specified flies listed on the product label | Follow label directions for use and removal. Rotate insecticide modes of action as appropriate rather than repeatedly relying on the same class. |
| Feed-through products | Immature flies developing in manure | They do not directly remove adult flies already on cattle. Results depend on the labeled use and consistent intake by the intended herd. |
| Sprays or pour-ons | Labeled pests treated directly on cattle | Suitability and persistence vary by product and label. These are not a complete solution to stable flies breeding around facilities. |
| Walk-through traps | Horn flies, where cattle can be routed through the device | Require suitable placement and regular cattle use. Arkansas Extension reports trial results, not guaranteed outcomes for every operation. |
| Sanitation and premise management | Stable flies and other flies developing around facilities | Remove or manage decaying organic matter, including old feed and manure around barns, feeders, and waterers. Pair premise sprays with sanitation when appropriate. |
The right choice also depends on handling and labor, cattle movement, product availability and labeling in your area, and the herd’s history with insecticides. Extension sources describe several delivery systems for cattle, but none makes identification or label review unnecessary. See the Arkansas Extension guide to horn-fly control and Minnesota Extension’s cattle-fly management guide.
#1 Best Overall
- Only Insecticide ear tag on the market that contains 40% diazinon. Effective against pyrethroid-resistant horn flies for up to five months. Utilizes the Allflew Universal Total Tagger. Available in a box with two 10-tag pouches or a case of 120 tags. Use as an ear tag to control flies. Use 2 tags for optimal contorl of flies and ticks.
Choose an approach for the fly you have
Horn flies
Horn flies are commonly addressed with insecticide ear tags, self-treatment devices such as dust bags or back rubbers, sprays, pour-ons, feed additives, and walk-through traps. Arkansas Extension says dust bags and back rubbers can be effective when properly used and maintained.
Use a monitoring threshold as a prompt to assess control, not as a universal rule. Minnesota Extension describes management around 200 horn flies per animal. Texas A&M AgriLife gives 250 flies per side before chemical control. The measures differ, and neither should be treated as interchangeable. Consult the relevant guidance for your operation: Minnesota Extension and Texas A&M AgriLife Extension.
Rank #2
- Pest Control for Cattle: Corathon Cattle Ear Tags control face flies, horn flies, gulf coast ticks and spinose ear ticks on beef and non-lactating dairy cattle
- Effective for Up to 5 Months: This livestock pest control is effective against face flies and horn flies for up to five months; Remove tags at end of fly season or prior to slaughter
- With Diazinon and Coumaphos: Formulated to control pyrethroid-resistant and chlorinated hydrocarbon-resistant horn flies
- How to Apply: Use Allflex Universal Total Tagger with red pin and black clip; See label for complete directions for use and application instructions
- Contains one (1) box of Corathon Cattle Ear Tags, with 2 pouches of 10 ear tags each (20 ear tags total)
If permethrin seems ineffective, do not assume that spraying more often will solve the problem. First confirm that the pest is a horn fly. UC ANR Cooperative Extension veterinary entomologist Alec C. Gerry notes that some horn-fly populations may be resistant to permethrin and other synthetic pyrethroids; his advice is to consider a labeled product with an IRAC code other than 3A. This is not a brand recommendation, and product labels and local availability still govern use. His response, dated August 20, 2021, is available at Ask Extension: Horn Fly Problem.
Face flies
Face flies are difficult to control because they feed on the face, a challenging area to treat, and spend substantial time off the host. Arkansas Extension describes forced-use dust bags positioned to contact the face, back rubbers fitted with face flips, insecticide ear tags, and feed-through insect growth regulators as options. Feed-through products require sufficient, consistent consumption by the intended cattle; they target developing flies rather than adults on the animal.

Stable flies and flies breeding around facilities
Look for breeding material such as old feed and manure around barns, feeders, and waterers, and remove or manage it. Minnesota Extension recommends pairing premise sprays with sanitation; it does not consider ear tags, back rubbers, dusters, or pour-ons effective controls for premise flies. A cattle treatment may address a labeled pest on the animal without stopping flies from developing nearby. Details are in Minnesota Extension’s guide.

Use traps and thresholds as tools, not guarantees
Arkansas Extension reports one walk-through-trap trial with a 57 percent overall reduction in horn flies and another with a 50 to 75 percent reduction in insecticide-application frequency. These are results from specific trials; they do not predict what every herd will achieve. Trap performance depends on cattle passing through and on appropriate setup. The figures are described in the Arkansas Extension horn-fly guide.
Thresholds likewise depend on the source’s counting convention. Use the stated unit—flies per animal or per side—and local Extension advice rather than combining figures into a single rule.

What to do when a treatment is not working
- Recheck identification. Confirm whether the flies are horn flies, face flies, stable flies, or another pest; treatment failure can reflect a mismatch between the product and the fly.
- Check how the method is being used. For self-treatment devices, verify that cattle actually pass through and contact them, and inspect and maintain the equipment.
- Review the active ingredient and resistance history. If permethrin appears to fail against horn flies, consider Gerry’s advice about a labeled product with an IRAC code other than 3A, and seek local guidance.
- Address breeding sites where relevant. For stable flies around facilities, remove decaying organic matter rather than relying on cattle treatments alone.
- Read the current label before applying or switching products. The label specifies permitted animals, target pests, application method, dose, withdrawal period, and handling precautions.
Do not mix insecticides with oil or apply them by a different method unless the current product label permits it. Product labels, local conditions, resistance history, cattle handling, and consistent intake can all affect whether a method is appropriate. A veterinarian or local Extension office can help tailor a plan. Arkansas Extension’s guides cover horn flies and face flies.
