Diatomaceous earth seems to bother/deter them, but it really doesn't kill them very quickly. During an infestation about five years ago, I was curious if what I'd bought and sprinkled everywhere was any use at all, so I captured a bug in a glass and absolutely covered it. It continued wandering around in there for 4 more days. But I agree with a lot of the rest of what you're saying :) Also: - double sided carpet tape is difficult, if not impossible for them to cross, so wrapping it around the leg of a chair or bed in addition to a trap can be a big help - you can measure the heat of a dryer with an instant thermometer by putting a few towels in the dryer and pulling them out right at the peak, before the cool cycle at the end, and tossing the thermometer right into the middle of them. Most dryers are suitably hot, but you should check before relying on it -- you should look up the temperature needed to ensure the eggs are destroyed, and always do a dryer run without washing first, so the heat applies directly and isn't just evaporating water! But after all that: lots and lots of stuff can be put in the dryer, and tied off safely afterwards in bags / taken away from a place it can be reinfested. - putting books or electronics in an oven, even set very low, is usually a bad idea.
