You’re a critter in the forest, peacefully munching on a tree — until it’s chopped down, turned into a pallet, and you’re shipped across the ocean. What do you do? Sometimes, the answer is escape, find defenseless trees in your new home, and eat them to extinction. The emerald ash borer, spotted lanternfly, “murder hornet,” and other invasive insects have all threatened destruction across North America in the past few decades alone.

Ben Bradford investigates why invasive bugs keep getting worse — and how, exactly, you’re supposed to stop millions of tiny creatures once they’ve decided they like it here. Schemes have grown increasingly intricate, including spy-movie hijinks, citizen squishers, the power of fire, and creating a Bug Fight Club.

Only some of these work.

Guests:

Andrew Liebhold, Chief Scientist, Forest Invasion Synthesis Centre

Chris Looney, Washington State Department of Agriculture entomologist (and murder hornet MacGyver)
