Bayvarol works by contact: the active ingredient is delivered continuously over the 8 week treatment period. As bees walk on the strip’s surface they pick up molecules of the active ingredient and then distribute them throughout the colony. Bayvarol is the only flumethrin-based apiary product that treats several successive generations of varroa mites, reducing mite populations in the hive by up to 99% in 1 application.

• Highly effective with up to 99% efficacy in Varroa Treatment
• Twice the contact area (4 strips/brood chamber)
• Easy to use rigid strips that don't curl
• 5-year expiry date from manufacture date
