Can anyone help me get rid of these annoying little bugs (see details)?

I’m trying to watch Blade Runner right now for the first time and I can’t concentrate because all these little bugs keep flying around me and the screen. I’ve been squishing them for about 20 minutes now and when I turn the light on, there’s more of them. They look a bit like fruit flies. They might be gnats, I don’t know. I don’t have any bug spray I can use on them. I’ve been spraying Febreeze because it’s all I have. This happens pretty much every year and when it’s a warm night at the drive in. It’s usually not this bad.

It’s a fairly warm tonight and I am annoyed that I have to shut the windows. So, please any help at all would be greatly appreciated. Thanks!
