Turns out the baby I sprayed with Windex was not dead, it was back where I first found it when I was going to bed so that time I sprayed it so much that there's no way it did not die (with an adult i would of gotten it completely but a baby cannot be that strong).

And this morning when I was coming back downstairs to do the computer part of my morning routine I saw a spider near the oil stove, called mom who got it.
