So there's something going on... There are these insects in our house. They come to bite every night but we don't know what species it is. Some say it's a fly or a sandfly or an ant. I don't know what it is actually..

If you guys know anything about this bug, please tell me. Here are the details: My grandmother says it has watery eyes and it feels like sand. My mother says it's bites are very painful. It comes at night. And it doesn't bite kids (because I didn't get bitten for two days!).

Please PM me quickly because we are dying to know so we can search on how to expose it. QUICK!
