Are fumigation fumes toxic?

Are fumigation fumes toxic, yes fumigation fumes are toxic and highly poisonous during fumigation period, which is why home must be vacated and sealed, but after proper aeration they are cleared and not toxic for reentry. For termite tent fumigation using Vikane sulfuryl fluoride, fumes are highly toxic to humans and pets, can cause respiratory failure and death if inhaled in high concentrations, as gas is designed to kill pests by disrupting nervous system, so home is tented and no one can enter during fumigation, with warning signs posted. However, Vikane does not linger, it aerates completely and leaves no residue, and after aeration period and testing showing zero gas, home is safe and fumes not toxic anymore. For indoor foggers using pyrethrins and other insecticides, fumes are also toxic if inhaled directly, can cause respiratory irritation, nausea, and allergic reactions, requiring vacating during fogging and ventilation after. So are fumigation fumes toxic, yes during fumigation they are toxic and dangerous, which is why strict safety protocols require vacating, removing pets and plants, and professional monitoring, but after proper aeration and clearance testing, fumes are gone and home is safe, with no toxic residue if done correctly, so fumes are toxic during treatment but not after proper ventilation and clearance.
