What characteristic makes acute poisons like strychnine particularly dangerous?

Acute poisons, such as strychnine, are particularly dangerous because they can be lethal with just one dose. This characteristic means that even a small amount can lead to severe illness or death, making them more perilous than substances that require larger quantities to have an effect. The rapid onset of symptoms often associated with acute poisons can catch individuals off guard, resulting in delayed medical attention and increasing the chances of fatality. Recognizing the immediate risk posed by these substances is critical for both pest control professionals and the general public to ensure safety and prevent poisoning incidents.
