A Lower East Side pest control company is fighting bed bug fear with humor. M & M Environmental, 32 Orchard Street, has rolled out a series of amusing t-shirts and an accompanying web site. You can see all of the designs at www.funnybedbugtshirts.com. The shirts feature assuring slogans, such as “Date Me: I’m Bed Bug Free” and “Bed Bug Free Forever.” New York City was, of course, gripped by bed bug hysteria last summer. The 2011 season (these critters love the heat and tend to hitch a ride with travelers) is just shifting into high gear. We profiled M & M Environmental (which has some very serious solutions to pest control) a couple of months ago.
