■ An inability or unwillingness to contract with a professional, often resulting in unsuccessful treatment
■ Denial or lack of reporting by tenants, landlords, businesses, etc., enabling infestations to spread further
■ Infested goods being sold in thrift shops, yard sales, and online via Craigslist, eBay, etc.
■ More people salvaging discarded items due to the down economy
■ Importation of goods from other countries with high bed bug activity
■ Increases in corporate relocations (e.g., call center staffing) from countries where bed bugs are prevalent
* Several respondents also mentioned the need for more training within the industry (for more on this topic, see the section on ‘Future Needs’). The majority of respondents (62%) reported bed
bug infestation to be a year-round occurrence, with no one season being busier than another (Figure 4). How- ever, 25% of those surveyed mentioned an increase in bed bug calls during the summer. Travel, moving, and other activities tend to be high during the summer months, which could increase the chance of trans- porting bed bugs into residences. During summer, the ambient temperature of some residences tends to be higher, which could result in a faster development time for some populations.
Just About Everywhere Bed bugs continue to be most common in resi- dences, with over 90% of this year’s respondents encountering them in apartments, condominiums and single-family homes. Similar frequencies of bed bugs in residences were also reported the previous year. Perhaps the most striking result in this year’s survey is the spread of bed bugs from housing and lodging to less ‘conventional’ settings. Many of these settings experienced statistically higher, double- digit growth in reported encounters by respondents compared to the previous year.
For example: ■ Hotels/motels—80% reported encounters this year, up from 67% a year ago
■ College dorms—54%, this year, up from 35% a year ago
■ Nursing homes—46%, up from 25%
