Deep Look | Flying Termites Take a Dangerous Journey to a New Life | Season 9 | Episode 2 | PBS

After the first big rain, western subterranean termites swarm by the thousands. Hungry ants, spiders and birds pick them off as they emerge from the soil. The survivors fly off to find mates, and quickly drop their delicate wings to start new underground colonies. If you’re really unlucky, they’ll build tubes of mud and saliva from their nest to yours.
