Just wondering if anyone knows how it is that Murphy's Oil soap works as well as 91% alcohol? I couldn't find any listed ingrediants in Murphy's, (such as alcohol).
Also, do either of these remove eggs? If not, is there anything besides heat/chems that can remove eggs? for example Hot Shot?

Somebody somewhere once explained what Murphy's oil soap does, but honestly I wasn't paying close attention at the time. (By then, I'd started treatment with a PCO, so some details just weren't important to me.)
Neither removes eggs.
Nothing that I know of removes eggs.
Heat will kill eggs.
The only pesticide that kills any eggs is, um, I'm not 100% sure which one it is. Bedlam, I think? I do know that there's only one.
Here's what I do know: there is only one pesticide that kills any eggs at all, but even it does not kill all of the eggs. That is why PCO treatments when done properly (unless they are thermal or Vikane, which must still be done properly) require more than one treatment in most cases.
Since there are no pesticides that reliably work on eggs, what you're basically doing with chemical treatment is putting down residuals to kill any nymphs that hatch from eggs that were not taken care of with the original treatment. And then on a follow up visit, you're trying to kill on contact any of the hatchlings that weren't killed while they were in eggs.
Done properly, steam should kill the eggs. However, except for more expensive steamers, to get enough heat to kill the eggs, you're also running the risk of introducing a lot of water into something, which can cause mold problems. So, if for example, you're steaming your mattress and then putting an encasement on it immediately, you may be causing a whole host of new problems.
I can tell you this, though. After the thermal treatment of my apartment, there were still eggs glued in place. The eggs were clearly dead, but even baking my whole apartment to 140 degrees for hours on end hadn't unglued the eggs that were glued in place. That glue? Not messing around. That's why even rigorous vacuuming won't remove the eggs reliably.

Both are contact kill of live bugs only.
Murphy is a gentle, all-purpose cleanser. Requires rinsing, leaves a little residue (that's what soap does, that detergent does not).
Alcohol evaporates, but damages paint and plastic surfaces.
Wash your "finished"stuff with Murphy. Spray that bug on your bed with alcohol. -

For what I hear, get a strong brush and brush everything, that will remove the eggs. I have an old fashioned broom with straw, that I use to clean the floors with and scrub real well.
I use garlic water as a repellent.
