Can I use for 5 year old?

Trin misread. Yes, you can use for you 5 year old child

Can I use it after got bite？

Certainly, however, should always apply before going out and enjoying nature. Protect your eyes, nose and mouth with cloth before spraying your head, neck area.

Can I use it indoor ?

Well, I spray it on in my laundry room before I go outside and I am in and out of the house all day and don't wash it off so I personally can't think that it matters if you are inside. I would think it might be good to spray it on in a ventilated place........
