The threat

Understanding the Varroa Mite Threat

The Varroa mite is the leading driver of honeybee colony loss worldwide. These tiny parasites weaken bees, spread disease, and can collapse an entire colony within a single season — and existing treatments are struggling to keep up.

Why it matters

The stakes go beyond the hive

Honeybees pollinate a significant share of the foods we eat. As Varroa spreads, the risk extends far beyond individual apiaries — impacting agriculture and food security at scale.

Beekeepers in the US have reported losses approaching 45% in recent years, with Varroa the leading driver. Without better tools, those losses threaten long-term colony health and agricultural productivity.

  • Rapid colony decline within a single season
  • Knock-on effects across ecosystems and food systems
  • Growing resistance to existing chemical treatments
  • Urgent need for sustainable, scalable solutions
The problem with current tools

What’s failing today

Traditional approaches are losing ground. Chemical treatments face growing resistance and risk contaminating hive products. Non-chemical options often demand labor and disruption most beekeepers cannot sustain.

Chemical resistance

Varroa mites are rapidly developing resistance to the most commonly used miticides, reducing efficacy over time and leaving beekeepers with fewer reliable options each season.

Residue and contamination

Chemical treatments can leave residues in wax, honey, and brood — raising concerns for producers, consumers, and the long-term health of the colony itself.

Labor and disruption

Non-chemical alternatives often require frame removal, transport, or hours of active management — stressful for the colony and unsustainable for working beekeepers managing multiple hives.

There is a better way.
