Prime Time Live ran an expose on the dangers of DEET on May 31, 1995. Insect repellents containing the chemical DEET are dangerous for human use, but political pressure from major chemical companies confounds attempts to regulate the dangerous ingredient. DEET is considered responsible for side effects including rashes, muscle twitching,confusion, slurred speech, seizures and even death. Most poison reactions to DEET probably go undetected even though nearly 5,000 DEET-related cases are reported each year to the National Centers for Poison Control.
