I suspect that the Flames were trying to trade him but that there's a short list of places he wants to go and those places didn't want him. He's probably off to the KHL.
Possibly. Although I bet they got into your house somehow anyway, so if they're determined to be inside I bet they'll find a way. Our spider friend appears to have ventured back outside on his own this weekend due to the warm sun.
I like stink bugs. They're harmless. When I find them in the house I tend to get them onto a stick or a pencil or something and I carry them back outside.
We do the same thing with spiders. For the most part a spider around the house isn't much of a problem and maybe they'll eat other bugs that show up. We had a yellow sac spider hanging around this week who didn't seem super interested in us. As long as they aren't biting me in my sleep I tend to leave them alone. Just give your bath towel a shake first...
