I recommend the author of the article
"Carpenter Ants and Foam Core
Panels" (JLC, 4/89) plant tansy
(Tanacetum vulgare), two plants on

To repair your house, infrared scan the
damage. Drill holes at the following
spacing: depth of foam times six or
seven, then refoam with water-based
urethane. Plug the 1/4-inch holes with
appropriate finish material and relax.
We built stressed-skin homes (expanded
polystyrene), which were badly
infested five years ago. Hence we
switched to Cedarfoam, which has
performed for five field years with no
infiltration so far.
We use shiplap for the panel joint,
which is simple and fast. We are
