Will Triazicide kill the 17 year cicada while the bug is still in the ground?

Triazicide is an insecticide designed to target a variety of pests, but it is not effective against cicadas while they are still underground in their nymph stage. The chemical primarily works on insects that are exposed to it after they emerge. Once the cicadas come to the surface, Triazicide can be effective in killing them if applied appropriately.
