Help! Nordic ware Bundt pan

Please can you help me clean this? This pan used to have egg muffins in it. So what I think is sticking to the pan is cheese and egg. I don’t know how to get this out of the pan. I have tried soaking it with soap and water. Should I try hotter water? Like boiling? I also tried comet and still nothing. I’m afraid to use steel wool on it.

Are these young roaches??

I moved into a new apartment a month ago. First thing upon moving in, I deep-cleaned, even before unloading moving trucks and putting anything inside my place. I found ONE dead roach (I'm pretty sure, had the spiny legs and everything) on a window sill and I've been on high alert ever since. Wiping surfaces with bleach, spraying with peppermint oil roach spray afterward, and I have a boric acid puffer on the way. When wiping cracks in the kitchen floor, I turn up with these tiny tiny little bugs that look to me like infant roaches? It's hard to tell because they're so small. Everything online says baby roaches are bigger than this, and it's weird that they still turn up where I've sprayed, but I have no idea what else they would be. Sorry, you'll have to zoom in pretty close on the picture because they're so small. Let me know if I'm on my way to a full-blown infestation.
