It’s probably just a sign of the times that the Department of Housing Preservation and Development has been sending out emails this week about the seminars it is holding about bedbugs. Complaints to 311 are skyrocketing, having doubled in the last 12 months. They are ten times what they were in 2003. Here’s the info on the Brooklyn session, which is one of three being held (the other two being in Manhattan and Queens). It takes place on Wednesday, March 12, 6-9 PM, at the Hope Gardens Senior Center, which is located at 195 Linden Street in Bushwick. It’s unclear if there are significantly more bedbugs around or if awareness and concern are just off the the scales.
