We are planning to visit Delhi this summer April/May. Heard mosquitos go on rampage. Whats the best way to protect my 4 yr old.

You can take precautionary measures to prevent mosquito bites: - avoid going out at night.  - wear long pant and sleeve if you need to go out at night.  - use mosquito repellent all the times. Re-spray every 6-8 hours. I choose non-deet and chemical free mosquito repellent like Babyganics Natural Deet Free Insect Repellent. You can purchase from iherbs.com at about $13 per bottle (6oz).
