The emerald ash borer kills ash trees in America’s forests and backyards. 

The wasps target the eggs of emerald ash borer beetles, which have killed more than 50 million trees in 25 states.

According to the Denver Post, the wasps can pierce beetle eggs and lay their own eggs inside, devouring beetle eggs.

Officials say the bug-on-bug war to save an estimated 1.5 million metro Denver ash trees depends on keeping the wasps strong enough to make it through winter.
