Fumigants are described as being what in terms of toxicity?

• A. Are highly toxic to all living organisms
• B. Are non-toxic to mammals
• C. Only affect insects
• D. Safe when used as directed

Answer: (A)

Fumigants are extremely toxic to living organisms; they are gases that diffuse through spaces and kill by disrupting cellular processes in any organism that breathes them. This broad, non-selective potency means they can affect not only target pests like insects but also humans, pets, and other non-target organisms if exposure occurs. Because of this, fumigants are described as highly toxic to all living things and require stringent safety measures, such as proper sealing of treated areas, controlled entry intervals, continuous monitoring, and appropriate personal protective equipment, and they must be used by trained professionals. The idea that they are non-toxic to mammals is not accurate, nor is the belief that they only affect insects or that they are safe when used as directed.
