FAQs on A Treat for Mosquitoes - 1 Class 5 Worksheet EVS Chapter 8

1. What attracts mosquitoes to humans?
Ans. Mosquitoes are attracted to humans primarily by carbon dioxide, heat, and certain body odors. When we breathe out, we release carbon dioxide, which signals mosquitoes from a distance. Additionally, body heat and sweat contain lactic acid, uric acid, and ammonia, which can also draw mosquitoes closer.
2. How can I prevent mosquito bites?
Ans. To prevent mosquito bites, you can wear long-sleeved clothing, use insect repellent containing DEET or picaridin, and avoid outdoor activities during peak mosquito hours, typically dawn and dusk. Additionally, eliminating standing water around your home can help reduce mosquito populations.
3. Do mosquito bites cause diseases?
Ans. Yes, mosquito bites can transmit various diseases, including malaria, dengue fever, Zika virus, West Nile virus, and chikungunya. It's important to take precautions to avoid bites, especially in areas where these diseases are prevalent.
4. What are some natural remedies to repel mosquitoes?
Ans. Some natural remedies to repel mosquitoes include using essential oils like citronella, eucalyptus, and lavender. You can also plant mosquito-repelling plants such as marigolds and basil in your garden to help keep them away.
5. How do I treat a mosquito bite?
Ans. To treat a mosquito bite, you can wash the area with soap and water to prevent infection. Applying a cold compress can help reduce swelling and itching. Over-the-counter creams containing hydrocortisone or antihistamines can also relieve discomfort.
