It looks like at higher levels is the same on both spells.
As for the beetles, you could include language similar to Find Familiar, where it lists some possibilities one being the beetles.
Perhaps as part of the 2nd one since it it is 5th level is that it does have an additional detection component similar to locate object that can find corses within a certain distance and then you can have them become digging-free undead from wherever you currently are instead if having to be just above them.
