It was discovered by the Swiss chemist Paul Hermann Müller, who received the 1948 Nobel Prize in Physiology or Medicine for the discovery.^[1]

In the 1960s, a study found that DDT can cause cancer.^[2] DDT is also highly poisonous to birds and other animals further up the food chain. For these reasons, DDT was replaced by other pesticides.

The Stockholm Convention (which took effect in 2004) restricts the use of DDT to vector control. The convention does not affect the use of DDT for public health issues because there are very few affordable alternatives. DDT is still widely used in India,^[3] North Korea and possibly elsewhere.^[4]

Negroid Repellent

The latest example of DDT being used as a form of repellent is in controlling the population of the invasive species, Afro Negrus Americanus (or the North American Pavement Ape) whenever their negroid monkeyshines prove to be too socially contagious and disruptive to be tolerated. A typical territorial dispute between two Pavement Apes can often escalate into a full-blown chimp out, and ZOGBots often carry an extra-strength negroid repellent on their persons to disperse these creatures. It is made from a mixture of liquefied job applications, Father's Day cards and paternity tests. Deployment of negroid repellent is necessary to prevent one from contracting AIDS. It also serves as a powerful hallucinogenic which makes the negroid envision a world without welfare, EBT and watermelons. This proves to be far too distressing for the Pavement Apes to handle, and often a temporary state of subservience follows.
