Elanco CyLence Ultra insecticide cattle ear tags — 20‑tag pack, up to 5 months fly & tick control

Elanco CyLence Ultra Insecticide Cattle Ear Tags are a 20‑tag pack designed to repel and kill face flies, horn flies, gulf coast ticks, and spinose ear ticks on beef and dairy cattle for months after application.

Engineered for herdwide pest management, CyLence Ultra combines beta‑cyfluthrin with piperonyl butoxide to deliver extended fly and tick control when applied to mature cattle. Each box contains two sealed pouches of 10 tags (20 tags total) and is intended for use with the Allflex Universal Total Tagger for straightforward attachment. These tags are labeled for use on mature animals, including lactating cows and calves aged three months and older; calves under three months should not be tagged due to potential ear damage. Read and follow label directions before use.

How long will CyLence Ultra ear tags protect my cattle?

When used as directed, CyLence Ultra ear tags provide sustained protection against face flies and horn flies for up to five months. Efficacy against ticks may vary with local parasite pressure and seasonality, so plan tagging to match peak fly and tick activity.

• Up to five months protection for face and horn flies
• Tick control for common species like gulf coast and spinose ear ticks
• Best applied before or at the start of high pest seasons

Which animals should be tagged and how many tags are needed?

Tag every mature animal in the herd for consistent control: apply one tag to each ear (two tags per mature animal) for optimal coverage. For calves, apply one tag per animal once they reach at least three months of age. Avoid tagging calves under three months to reduce risk of ear damage.

• Mature cattle: one tag per ear (two per animal) recommended
• Calves: one tag per animal at three months or older
• Use Allflex Universal Total Tagger for accurate, safe placement

What active ingredients are in these ear tags and how do they work?

CyLence Ultra combines 8% beta‑cyfluthrin, a modern pyrethroid, with 20% piperonyl butoxide, a synergist that enhances insecticide activity. The combination reduces fly irritation and kills contact pests on treated animals, contributing to herd comfort and decreased parasite loads when used as part of a broader integrated pest management plan.

• 8% beta‑cyfluthrin — a fifth‑generation pyrethroid
• 20% piperonyl butoxide — synergist that boosts effectiveness
• Works by contact activity against flies and ticks on treated animals

How should I apply and store the ear tags for best results?

Apply tags using the Allflex Universal Total Tagger according to label instructions; ensure proper ear placement and clean tagger components between animals. Store unopened pouches in a cool, dry place away from direct sunlight and out of reach of children and pets.

• Use the Allflex Universal Total Tagger for reliable application
• Follow label directions for placement and safety precautions
• Store sealed pouches in a cool, dry, secure location
