1. Insect repellents are substances that are applied to skin, clothing, or other surfaces to deter insects from landing or biting.

2. Different kinds of insect repellents have varying efficacy rates. Some common active ingredients in insect repellents include DEET, picaridin, oil of lemon eucalyptus, and IR3535. These ingredients have different levels of effectiveness against different types of insects.

3. Insect repellents that are available in the market but are not organic, such as Baygon, often contain synthetic chemicals that can be effective in repelling insects. However, they may also have potential health risks and environmental concerns.

4. Studies have been conducted on organic insect repellents, such as those made from natural plant extracts like citronella, lemongrass, and peppermint oil. These organic repellents are generally considered to be safer for human use and the environment, but their efficacy rates may vary.

5. Some commercially available organic insect repellents include products containing essential oils like citronella, eucalyptus, and lavender. These natural ingredients are believed to repel insects through their strong fragrances and potential insecticidal properties.
