Remove the attached tick with clean tweezers, apply an approved acaricide to the bite site, and notify a veterinarian to evaluate for disease risk.
If a cow has a tick, what should you do? - in detail
When a bovine animal is found with ticks, immediate action is required to protect the herd’s health and prevent disease transmission.
First, isolate the affected individual. Move the cow to a clean paddock away from other livestock to limit the spread of parasites. Keep the area free of tall grass and debris where ticks can thrive.
Next, conduct a thorough physical examination. Use gloves and a fine‑toothed comb to locate all attached ticks. Remove each specimen by grasping it close to the skin with tweezers or a tick removal tool, pulling straight upward with steady pressure. Avoid twisting or crushing the body, which can leave mouthparts embedded and increase infection risk.
After extraction, disinfect the bite sites. Apply an iodine‑based solution or a veterinary‑approved antiseptic to each wound. Monitor the skin for swelling or discharge over the following 24‑48 hours.
Treat the cow with an appropriate acaricide. Choose a product registered for cattle, following the manufacturer’s dosage and withdrawal guidelines. Options include:
- Pour‑on formulations applied to the backline.
- Injectable systemic acaricides delivering protection for several weeks.
- Oral drenches when resistance to topical agents is suspected.
Rotate acaricide classes periodically to prevent resistance development. Record the product, batch number, and application date in the herd health log.
Implement a herd‑wide tick control program. Strategies include:
- Pasture management: rotate grazing areas, maintain low grass height, and eliminate brush where ticks hide.
- Biological control: introduce tick‑predatory beetles or apply entomopathogenic fungi approved for livestock environments.
- Regular inspections: schedule weekly checks during peak tick season and after heavy rains.
Finally, consult a veterinarian if any tick‑borne illnesses are suspected, such as babesiosis or anaplasmosis. Early diagnosis and treatment improve outcomes and reduce mortality.
By following these steps—segregation, careful removal, disinfection, targeted acaricide use, and comprehensive herd management—farmers can effectively address tick infestations and safeguard animal welfare.
