As far as the animals, sounds like you're doing the best you can. Humane traps and not wanting to poison mice sounds humane to me. I gather the coyotes aren't killing the raccoons?

I urge you to get light-blocking curtains, at least for the bedroom. Some of them also block heat. I have one set tied back with the window open. When all four are down it gets stuffy but a fan in the window might help with that. I got them for cheap from Amazon. Make sure you read the reviews.

That heat sounds UNBEARABLE. We're having low 90s and there's no way I'm using the oven.
