Stay out of motels and hotels.
I got a few bites on me after staying in a pretty expensive hotel.
My wife who was in the same bed didn’t get any.
I NEVER unpack my luggage at any hotel ever anymore.
I always put the bag on a luggage rack off the floor.
When we got home I left the bags in the garage.
Took all the clothes and immediately into the washer then dryer on high heat.
Then the carry on bags went in the dryer too.
Plus a back pack I had brought went in the dryer.
I also called the hotel and spoke to the manager.
True; even if the owners spray a lot. When I stayed at a long-term motel I learned to bag the mattresses and keep a cup of water on the night table to drown the super ones who overcame that. Despite all that pesticide resistance the bastards drown in less than a minute.
I believe the bed bugs, like previously eradicated diseases, have been spread by illegal aliens.
