Defeat The Enemy

To truly understand the importance of controlling horn flies in Oklahoma, it's important to understand the horn fly life cycle, the economic threshold for horn flies on beef cattle, and the potential to promote weight gain through simple and cost-effective horn fly control, rather than through the use of labor-intensive back rubbers and ear tags. Altosid® IGR provides consistent horn fly control all season, with less labor. As your cattle graze, fly control is dispersed in manure to combat horn flies and break their life cycles.

Effectively Control Horn Fly Populations

From preventing common diseases and combating weight and blood loss to increasing cattle comfort, our team of experts has the answers and resources for you to protect your herd and bottom line.

Horn flies are the number-one economic ectoparasite in North American cattle production, causing an estimated $1 billion loss annually.

Adult horn flies live 2 to 4 weeks, taking 20 to 40 blood meals per day.

Studies have shown that at a level of even 200 flies per animal, your bottom line and animals will begin to see the effects. When left untreated, horn fly infestations can reach up to 4,000 flies per animal, staying on the cattle both day and night.

An IPM program includes biological, physical-mechanical, and cultural efforts to reinforce your fly control. A comprehensive IPM program consists of three phases: Planning, is essential to continually monitor the results to evaluate the effectiveness of the program.

Altosid® IGR delivers the most effective, cost-efficient control of horn flies with:

  • No extra work rounding up or handling cattle as with ear tags, back rubbers, and sprays. The animals distribute the active ingredient for you.
  • No withdrawal times required before culling or milking.
  • No known instances of resistance in nearly 50 years of use -- a common problem for other horn fly control options such as ear tags if not administered properly.
