Wasps released in Ontario to fight emerald ash borer

They’re so tiny you can hardly see them but these little wasps may be the answer to saving the ash tree population in Ontario.

The federal government has approved the controlled release of two nearly identical species of wasp that feed on the eggs and larva of the emerald ash borer. The wasps do not have stingers and are around the size of a piece of sand.
