DDT works by disrupting the nervous systems of insects. It interferes with the movement of sodium ions in nerve cells, causing neurons to fire repeatedly and uncontrollably. This overstimulation leads to spasms, paralysis, and eventually death. Because DDT acts as a contact poison, insects do not need to ingest it to be affected; simply landing on or touching a treated surface can expose them to the chemical.
