NPMA LIBRARY UPDATE Some pest management firms have determined that their technicians should do some or all of the preparation to minimize the risk of translocating bed bugs or disturbing populations prior to treatment. Whole-room heat and fumigation treatments require all belongings and furnishings to be left in place, however additional treatment-specific preparation is required.

8.4. Any treatment preparations should be appropriate to the type of site being treated (single family home, multi-family housing, hotel/motel, office, etc.).

8.5. Treatment preparation instructions should be communicated before the technician arrives to perform the service.


Involvement from property owners, hotel managers, office managers, and other responsible parties is essential and includes: 8.6.1. Communicating with tenants, clients, employees, etc. 8.6.2. Allowing inspection and treatment (as needed) of adjoining sites. 8.6.3.

Permitting adequate follow-up services.

8.6.4. Correcting structural deficiencies that may contribute to bed bug problems such as loose molding, peeling wallpaper, etc.

8.6.5. 8.6.6.

Instituting housekeeping practices to prevent or reduce the spread of bed bugs. Educating staff on prevention and control of bed bugs.

9. Bed Bug Detection 9.1. Before providing bed bug control service, a pest management firm should determine whether treatment is necessary based on a careful inspection and the needs and concerns of the client.

9.2. 9.3.

Live bed bugs are evidence of an infestation, but sometimes are difficult to observe in low-level infestations.

Intact, unhatched, or viable bed bug eggs are evidence of an active bed bug infestation.

9.4. Bed bug cast skins, bed bug fecal staining on sheets, and fecal staining near typical harborage sites may be considered evidence of an active infestation if the area has not been previously treated.

9.5. When a live bed bug or viable eggs cannot be located during an inspection, the technician should make further effort to confirm the infestation through a more aggressive inspection or other methods that have proven effective for bed bug detection.


Some clients may elect to have an area treated based on reports of bites or the proximity of other infested areas, even if visual evidence of infestation cannot be confirmed.

9.7. The presence of bites or assurances by residents that bed bugs are present should be considered carefully. 9.7.1.

9.7.2. 9.8. Skin infections and conditions can also look like insect bites.

9.7.3. Confirm that the pest is the bed bug, Cimex lectularius, and not any of the closely related bugs that infest bats and birds, which require different control tactics.

In addition to visual inspection, supplemental information may be useful including: 9.8.1.

9.8.2. VI 9.8.3.

Reviewing pest control records for a building to track previous bed bug complaints, confirmed infestations and prior bed bug treatments or services.

Speaking with building owners, occupants, and staff about the history of bed bug problems at the site.

In residential accounts, determining where people sleep and rest outside of the bedrooms.

It is not possible to tell from an apparent bite if it was caused by a bed bug because bite reactions vary, and bites from other insects may have similar appearance to those of bed bugs.
