I ditto this one.
I’ve found the opposite is true in my circles. The key to keeping bed bugs away is ..
... Cleaning the house.
I live in a relatively new farmhouse (it’s only 100 years old) and believe me - I can show you some sort of rodent or bug in under 10 minutes of looking. (wolf spiders are my common find. I hate spiders.) and I can sweep my floors in a continous loop for eternity and still sweep up piles of dirt (As someone in a 100 year old house can agree) but we’re good to go.
I run electric stove, but I run coal heat.
The ONLY way that people get them, when they are normal people, who keep things clean, is when they come in through something brought into the home or hotel, by people who have them and aren't "clean".
