The majority of people who self-harm through pesticide poisoning do not intend to die.
Self-harm is usually a spontaneous act, one that is not planned or thought through. Research shows that more than half of the people who harm themselves by ingesting pesticides decided to do this less than 30 minutes before committing the act. The introduction of acutely toxic pesticides meant that acts of self-harm with household poisons, which were previously relatively harmless, then became lethal.
For every death, there are 20 attempts to self-harm. Whether or not someone dies depends on the toxicity of the pesticide they have to hand.
