Well, they aren't nesting in cracks per se... they're under the eaves, on 
the flat smooth board behind the fascia board and on the smooth sides of 
the century plant leaves.

That's the thing, they're not nesting in the tight spaces between the 
leaves - the dern leaves are about 4-5 inches wide and 10 feet long - 
they're mostly nesting on the undersides and behind the fascia board in the 
same general area. It may be an odor from the plant that only they can 
detect or something like that.
