Bed bugs have made a resurgence in homes, office buildings, college dormitories, retail stores and other public and private facilities. An alternative to using pesticides is removing visible bugs and eggs with a vacuum’s crevice tool.

Vacuum under desks, on chairs and even walls. Follow this with steam cleaning to penetrate seams of upholstery, cubicle dividers and desk crevices to kill bugs and destroy eggs.

After cleaning, janitors should change out vacuum bags immediately, seal them in plastic bags and discard them in outdoor containers. If cleaning crews store vacuums on site, janitors should monitor the storage area as the vacuum itself can be a common residence for bed bugs.
