From what I understand, cleanliness has nothing to do with bedbugs. And they are hard to kill with pesticides too; that's why they are such a problem for New York.Most houses do not have bed bugs, tho they are a growing problem like roaches. Every single house does have dust mites, which are bugs. Having either of these in your house has nothing to do with how you do your laundry. No matter what you do you won't get rid of the bugs in your house. That's supposed to make you all feel better, not worse, by the way. Not sure if it came out that way or not.
But then, who's going to believe me since I don't wash anything separately, don't use hot water, don't use bleach. But I have managed to make it almost 50 years without any problems caused by my casual laundry practices.
I'm just glad they haven't really made it down here yet, though I'm sure with all the travel, someone is bound to pick them up and spread them everywhere.
