We are currently working on a touch cart that would serve our Hall of
the Americas. One of the areas we cover in this hall is the Southeast
and the design of this touch cart would include a 4 foot replica of a
Caddo "beehive style" house. For this we are considering using tree
saplings to be bent into the right shape.

My question is: how does one treat the wood to prevent any insect
infestation?  I would prefer to stay away from using chemicals for
obvious reasons. Any thoughts?

Many thanks and best wishes,

Dirk Van Tuerenhout
