Do you have a link to an alternative site with information about bedbug density made since 2018 or so?

I'm not saying you're wrong, I'm saying that in lieu of additional information this is what I have to work with, so I will need a better source of data before I change my mind.

Bedbugs die much more easily than that, 45C for 90 minutes will do it. The most expensive extermination method for bed and bugs is to seal up the home similar to the way it's done when using pesticides, except they just blast heat into your home for like 8 hours. Kills the bed bug infestation inside completely, but because there's no residual poisons bedbugs from outside can start a new infestation easily. It works great for homes, not worth doing for apartments.

Put it in a Uhaul box for a day in summer heavy sun. It already hits 160f / 71c routinely in summer in a closed vehicle.

Ive done that when getting old wood furniture from facebook. We bake it for a day or 2 in a closed trailer. If there was anything living on or in it, it isn't after the bake.

And the temp doesnt damage what we do that to in any way.
