Tenting is not the only way to get rid of drywood termites. Alternatives include localized treatments with liquid or foam termiticides, heat treatments that raise temperatures in affected areas to lethal levels, and microwave treatments targeting termite colonies. These methods are effective for small or contained infestations but may not be sufficient for extensive termite activity. Tenting is the most thorough option for eliminating widespread drywood termite infestations as it ensures complete penetration and extermination.
