Ugh, bedbugs. My partner used to live at his fraternity house where they were always taking in new couches/furniture, and eventually they got hit. We got bit the worst, a lot of the others who lived there didn't have so much as a bite on them.
They tried all kinds of remedies, but eventually had to suck it up and call the exterminator...they all have to be dead, otherwise they'll just multiply again. and this was about 8 months ago, apparently they just had to call the exterminator again last week so gross.
