You should have next 0 larva at all times. What use is is a larva if it's not being morphed? It just sits there, doing nothing. If you have money, and larva, build units. If you have larva, but no money, build drones.

The only situation where you want excess larva, is if you're at 200/200, and banking minerals and larva. Even then, staying on 200 just lets them catch up, so go in, get rid of some supply, back off, and get the right combination.

Also, when you have 3 larva at a hatchery, that hatchery will no longer make it's own larva. So you're really just giving yourself less possible units.
