What is the best tick control protocol for livestock?

An effective tick control protocol relies on chemical acaricide rotation (such as alternating Amitraz with synthetic pyrethroids like Cypermethrin), treating the entire herd simultaneously, and keeping stockpens and dip tanks clear of organic debris.

How do ectoparasites develop resistance to acaricides?

Resistance develops when the same chemical active ingredient is applied repeatedly without rotation, or when sub-lethal concentrations are used. Surviving parasites reproduce, passing on resistance genes to future generations.

Are there withdrawal periods for livestock ectoparasiticides?

Yes, animal ectoparasiticides carry strict milk and meat withdrawal periods. Generally, milk has a 0 to 24-hour withdrawal, and meat requires 1 to 7 days before slaughter. Always review the product label.

How often should I dip or spray my cattle?

The frequency depends on the local tick pressure and season. In high-risk areas during peak tick seasons, dipping every 7 to 14 days is common. Always monitor tick loads and consult local veterinary guidelines.

Is it safe to mix different acaricides together?

Never mix different classes of acaricides in the same tank unless explicitly directed by the manufacturer. Mixing can cause chemical antagonism, reducing efficacy, or create toxic compounds harmful to the livestock.
