I'm renovating a bathroom in my home in Maryland. I found this insect activity when I removed the drywall. Was it made by termites or carpenter ants, or hopefully, some benign insect? It doesn't look like there is damage to the wood, although I don't know what is happening between/inside the studs.
Is this Termite or Carpenter Ant Damage

Tell-tale of carpenter ants would be sawdust on floor or surroundings of the tunnels. Carpenter ants do not eat wood; hence, when they bore tunnels through wood, they push out the bits of wood through the holes in the wood which then accumulate in piles.
In the photographs appear to be the typical termite mud tunnels. Termites consume wood and then cover their tunnels with saliva, mud, and fecal matter. The dirt trails you see are called “mud tunnels.”
