The choice between heat treatment and fumigation for termite control depends on the specific situation. Heat treatment is chemical-free and environmentally friendly, requiring less preparation and allowing re-entry into the home within a few hours. However, it may not penetrate all areas where termites reside. Fumigation is more comprehensive, reaching termites in inaccessible areas, but involves the use of toxic chemicals, requires vacating the premises for several days, and necessitates extensive preparation.
