Neither of these approaches is a good idea. Bleach is very irritating and has very little if any residual action..  Baking soda is useless.
  for self help, there are a lot of other things you can do.. vacuuming , steam treatment, (some steamers are very reasonable in price.. handhelds are USELESS. ) DE used carefully in outlets and cracks and crevices, not as a dust everywhere.. not good for anyone..
buy some leg protectors and matress and box spring encasements, and get a good professional firm to do the heavy duty stuff..
