I have come back to my house after a month and found these black things scattered throughout my laundry room. Could they possibly be dead ants since it was near a spider web.

Additionally found some pile of just stuff littered across the door in the same room that seems to have dead bugs and other stuff in it. What could that be and should I be worried.

Are there any further steps I need to take?

I have a YAS200 Yamaha Advantage Alto Saxophone that I have not used in over a year now. I want to get back into playing regularly again and I was wondering if there was a proper way to self clean/sanitize everything from the body to the neck and mouthpiece. I want it so that it is clean enough to play regularly again.
