A common household mosquito repellent may be silently harming the bees in your garden. Dr. Kimmo Kaakinen shares his study on how volatilized prallethrin—used in household vaporizers and portable mosquito repellers—impairs bumblebees' ability to navigate home. We learn why a 20-minute exposure can reduce homing success from 37% to just 5% and what this means for colony survival. Learn how understanding these threats gives us real power to make a difference for wild bees.

What happens if the essential work of Europe’s wild pollinators suddenly disappears? Dr. Arndt Feuerbacher joins us to share insights from his study on how wild bees underpin Europe’s agricultural stability and what their decline could mean for food security around the world. We dig into what needs to change, why managed bees can’t fill the gap, and how local actions can add up to real impact.

How can creativity, collaboration, and ecological know‑how turn even the most unlikely landscapes into thriving habitats for pollinators and people? We visit Indian Lake, New York, where a capped landfill is being transformed into a vibrant pollinator meadow. Kristina Hartzell and Kailey Maher from ADKAction share how this innovative project began, what they’re learning from early test plots, and why native plants are key to restoring biodiversity on disturbed land. We also explore the role of community partners—from local schools to volunteers—in bringing this once‑forgotten space back to life.

We head to the quiet Mediterranean island of Giannutri, where researchers ran a rare experiment to understand how managed honey bee colonies affect wild bees. By temporarily closing the island’s honey bee hives, they watched nectar and pollen levels rebound almost immediately—giving wild bees the chance to take the lead in the pollination network. Dr. Lorenzo Pasquali shares the story from Giannutri which raises important questions about how we manage honey bees in sensitive landscapes if we want both wild and managed pollinators to thrive.

Think pesticide assessments protect wild bees? Think again. Dr. Sabrina Rondeau uncovers how soil pesticide exposure threatens ground‑nesting bees; risks overlooked by current regulations that focus only on honey bees. Her research reveals why we need stronger frameworks that reflect real‑world conditions to safeguard pollinators and protect biodiversity.
