Maggots

I have maggots in my car and I have no idea what to do. I know for a fact I will not be able to handle cleaning them out myself. I tried to go to my mom for help but she just went "It's good for you to figure this out by yourself". Now I'm crying and I feel like I'm going to throw up. I set up a fly trap to catch any adult flies but I have no idea what to do about the maggots.
