I haven't been overly worried - surprising, as I"m the type to obsess over things at times. And they're reported to be more on the rise here in Ohio as well. When it's on my mind, I'll do a quick check of the matress but that's about it. Probably should take some precautions as mentioned in the link above. I do generally throw all my clothes into the washer straight from my luggage anyway so I guess that helps.
