Mud daubers on fragile surfaces

I received the following query from Melissa Heaver
<melissa-heaver<-a t->nthp< . >org> of the National Trust for Historic
Preservation (NTHP) who is not on the list:

    Drayton Hall, an NTHP property located near Charleston, South
    Carolina, is one of the finest examples of colonial Georgian
    Palladian architecture in the United States.  By policy, the
    house is and will remain unfurnished and unrestored.  Efforts
    are on-going to stabilize the structure and maintain it so that
    the house can be interpreted for its architectural and historic
    significance.  A good portion of the original interior wall
    finishes remain, but are extremely fragile.

    Drayton Hall has a problem with mud daubers inside of the
    structure and is seeking advice on safe removal of the tubes.
    The daubers have been killed, however, because of the fragility
    of the paint surface, tube removal removes some of the paint.
    Has anyone had any experience with this that can offer advice?
    Thanks.
