Damage From Carpenter Ants

Carpenter ant damage in styrofoam insulation.
When this is happening you can hear the ants chewing the insulation and spitting it out. This is one of the things t hat show that carpenter ants do not digest the material that they are chewing. They do the same thing in wood. They are making galleries where they can put their larvae and pupa until they hatch out into ants. This kind of damage has now been found in Icynene Insulation. Carpenter ants certainly have the ability to chew Icynene.
