Follow visible ant trails to likely entry gaps and photograph the route before cleaning or sealing. Coarse frass near wood can be evidence of carpenter-ant activity, but identification requires closer inspection. Reduce accessible food and moisture, and inspect plumbing and wall penetrations instead of relying only on surface spray. Check mulch, vegetation, siding clearances, and utility entries. Treatment scope should follow confirmed evidence.
