Wood to ground contact in any type of structure is an invitation for subterranean termite infestation.
These photos came from a house where the homeowner attached boards to the piers to hold lattice between the openings.
In figure 2, close inspection reveals Formosan termites using the board as a bridge to enter the house.
Figure 3 shows that at some point in the history of the same house, someone repaired the sill and placed this large wood beam as a support. Now the Formosan termites are also using it as an entrance point into the house.
