They sure are!!! Just be diligent and search, search, search. My husband knows that if he accidentally brought them home, my family would have to visit me on the locked down psych ward. I just don’t like parasites to the point that I took a hot shower right after reading the initial post!!

“A little DDT will beat them back”.

Seems to me that when we used DDT, we had a lot less critters. Got to go now... I’m taking another shower.

The bedbug genes didn’t KNOW about insecticides. That’s not how evolution works.

Spray insecticide on 20 million bedbugs and all of them die, except for a few. Those few bugs survived because they had some genetic difference, some flaw. Lucky hit, nothing more.

It’s taken most of a century for that small colony of lucky bedbugs to spread back into their old range. You see the same thing with disease bacteria, mold, etc. Evolution never stops.

“Bedbugs have been around for MILLIONS of years yet insecticides are a very recent manmade development. So how did the bedbug have sophisticated genes that could resist these insecticides?”

The few that are resistant to the insecticide survive and produce the next generation, and so on until the entire population has that ability.

These bed bugs didn’t “evolve” these defenses over the last couple decades, they already had them encoded in their genes.

The Evolutionists are so dedicated to the primary axiom that they see Evolution in every thing, even in the design of sport cars.

Beat me to it. I’m still waiting to hear one living thing that has been observed to have “evolved” into another species. Then again I’m not into the church of pseudo science, so maybe I’m unworthy.

How hot is the air that comes out of my blow-dryer? If it’s hot enough, couldn’t I just blow-dry the mattress and sheets at the hotel for a few minutes to get rid of any bugs I didn’t see when I checked the sheets and mattress?

What has been done with other species, like the screw worm, is bringing “spent cartridges” (irradiated sterile individuals) into the population; since those species mate once and die, that effectively reduces the bugs’ numbers.

I don’t think a blow-dryer would work. Even if it were hot enough, you’d have to treat every possible location for the right amount of time (a few minutes or more).

Better to use google to get some good tips, here’s one site I found interesting:

In addition.... there’s a site, I think ... that tells you where people have reported bedbugs.

Right here http://bedbugregistry.com/.

Agreed. Bedbugs, along with a myriad of diseases. Oh well! “Our Diversity Is Our Strength!”

The government causes efficient insecticides taken off the market....DDT for one decades ago and hello malaria which was almost wiped out world wide.....My bee man use to be able to come out and spray my home once a summer to get rid of yellow jackets, wasps, bee's but 5 years ago the government outlawed the insecticide he used...the environmental nuts raised cane... Raid use to be more effective years back, not as good any more... Which begs the question is it the bed bugs or the government that causes the problem.

You can borrow books that are sewn - no metal staples, etc.

Have a collection of ziploc bags. Put each book you borrow into a bag before taking it home.

Run them through the microwave for a minute or two.

A year ago, I’d have fully supported your Kindle choice, but the book prices for the Kindle are getting ridiculous. I’m slowly going back to pulp when the book I want is cheaper that way than the eBook.

Bedbugs are not attracted to filth.

In fact, IIRC, other insects crawling around in filth (probably spiders) will control the bedbugs. So the bedbugs do better if they have a monopoly on the clean territory.

Yes, yes, spiders are not technically insects but you get my drift. BBs can’t thrive if other things are eating them.

I’m guessing the fire killed the bugs, but weren’t the springs a bit lumpy to sleep on afterward?
