Testing Insect Repellent Effectiveness

The video tutorial by Consumer Reports demonstrates the testing of insect repellents for effectiveness against mosquitoes and ticks. It explains the procedures for testing topical repellents on human subjects in controlled environments, ensuring safety by using disease-free insects.
