Terminix has seen an increase in the prevalence of bed bugs in most states since releasing its first Most Bed Bug-Infested Cities ranking in 2010. With the growth in bed bug populations across the U.S., businesses continue to represent 70 percent of Terminix's bed bug customers versus 30 percent for residential customers.
"In areas with high levels of active bed bugs, it is not uncommon to see a 300 percent increase in reported incidences over levels reported just a few years ago," says Paul Curtis, director of service quality for Terminix. "And in areas where infestation is newly discovered, increases can be as high as 1500 percent over the previous year."
While some locations are more susceptible to infestation than others, bed bugs are transferred by people: the more people traffic a location has, the more it is at risk.
For office buildings, the high volumes of traffic create a special challenge, as do personal items brought from home. Many areas can harbor bed bugs including cubicles, employee lockers, break rooms and electronic equipment.
"Discovery of suspected infestations or bed bug activity often comes via complaints from visitors or employees," adds Curtis. "It's important for facility managers to develop an action plan in advance with their staff."
Suggestions for Developing the Right Action Plan:
• Train and educate all staff members on how to look for signs of infestation and what to do if bed bug activity is found.

• Conduct regular inspections of vulnerable areas and train employees to self-check, since it can be difficult to inspect personal items, the most likely source of infestation. In addition to a bed bug, you may see eggs, fecal spots or cast skins as sign of infestation.

• Train staff to handle visitor and employee concerns related to bed bugs sympathetically, professionally and according to company policy. Legally, employees' actions and words could be imputed to their employer.

• It's most critical to be quick and responsive — if you suspect bed bugs, contact an expert immediately to schedule an inspection.

• Preserve samples of the suspected evidence to show to the expert during inspection.

"Bed bugs continue to plague many U.S. cities and towns and they are able to hitchhike on any item and be carried into any home or building," said Stoy Hedges, an entomologist with Terminix. "While major metropolitan areas are most at risk, it is important to note that bed bugs have been spotted in cities and towns across the country."

Hedges cautions that bed bug infestations are not something that schools should attempt handle on their own. A recent report in the Journal of Economic Entomology reported that over-the-counter foggers have been proven ineffective and are not recommended for use.
