Accidentally left fruit upstairs and now there's bugs?!?

So I did something really stupid lol. I sliced up pears and brought it to my room one night but I forgot to finished it and I put it under my bed. After a few weeks my house starts to have small flying bugs and I checked under my bed and it's full of those things. So I threw away the source of the bugs but there's still some left over. The thing I'm scared about is what if they reproduce and stuff?! I can't let my parents know this, they'll kill me. I know it's irresponsible of me ... Does anyone know how to get rid of them without the help of my parents? They look like baby flies or something, not sure what they are, this is my first time something like this happened
