Does smashing walnuts kills the pests that invade it?

[astralus]

If you smash a walnut with eggs of a pest already laid in it, or on it, and throw it away on the ground, can these eggs still hatch, and live, and for how long is that possible. I know it is an odd question, but indulge me please, it is a bet.

Someone asked how hard did I smash it - real hard, the idea was to kill the live insect inside (not the eggs). How big is the risk from further infestation, can hatch if there were eggs and live for how long, can the insect that lived inside survive if I didn't kill it?

Depends whether you smashed the insect/eggs or not. If not, then it probably survived, but it's questionable, how long would it survive. The larvae from nuts would probably not be able to find new source of food.
