Are ants and termites a problem in panels?
No more than in conventional construction. In climates where either termites or ants can cause problems, panel manufacturers recommend that all homeowners use the same preventive treatments (topical sprays around foundations, termite shields, etc.) they would use in a stick framed home. Preventive measures at the time of construction will aid in preventing infestation. Check with officials in your area. Expanded polystyrene (EPS) is non-intrusive to insects.
