How can I effectively test insect repellents?

What are the best methods to test insect repellents?

You can test insect repellents using field tests, lab tests, or controlled environment tests. Would you like details on each?

Yes, please explain the field test method.

In a field test, apply the repellent on your skin and expose yourself to insects in a natural setting. Record the duration of protection.

How do I ensure the test is fair?

To ensure fairness, use the same conditions for each test, like time of day, location, and the same type of insects.

What should I do if the repellent doesn't work?

If it doesn't work, check the application method, concentration, and expiration date. You might also want to try a different product.
