Flies laid eggs in my car...

Idk what group to put this in but ladies... how the hell does this happen?!

Yesterday I left for lunch and there were like 5-10 flies in my car and I had all my windows up so I'm thinking what the hell?! So I drove with the windows down to try and get them all out. Well I didn't think I got them all out because on my way home there were still a few flies in my car. Not really thinking anything of it. Just found it odd. But then this morning I go out to leave for work and I see a fly on the inside of my window and I think jeez not again. So I open my door and alllll these flies just start flying out. I go inside and tell my mom "I think flies laid eggs in my car!" So she follows me outside with big spray and tells me to open the trunk. I literally have nothing in my car except my bookbag and a sheet I have my bf and i's dogs sit on when they're in my car. So I open the trunk and tons of more flies start flying out. So I lift the only thing I have in my trunk up, the sheet, and there's dead larva under it 🙀🙀🙀🙀🙀🙀🙀🙀 They did lay eggs in my car which really grosses me out! I think the dogs somehow brought in the flies because it was under the sheet I had in my trunk. Hahahaha omg this is my life. Just had to share with you ladies!!
