Roaches Check In, But They Don't Check Out..

My apartment is clean but not airtight, so I've taken some action:

I wonder how many roaches fall for this farce.

"Comon' in!! We're all dying!"

Every roach motel needs a weather vane so they can tell what direction the spray is coming from.

Inside the death chamber.

"What's going on in here?"
"Um...death?"
