Specifications include, but are not limited to: 4.1.3 Exterior Treatment 1. Contract includes treatment of exterior of buildings only. A barrier treatment of residual insecticide will be applied to the exteriors of all buildings on each campus/center. This barrier will extend to at least three (3) to four (4) feet around, and where appropriate, two (2) to three (3) feet up the sides of the buildings. Areas that may provide harborage to insects, such as sprinkler system control valves, meter housings, dumpsters, manholes, etc. will also be treated. 2. When appropriate, exterior landscaped and courtyard areas will be granulated. When necessary, exterior treatment may be required. 4.1.4 Interior Treatment 1. Interior treatment will include quarterly visual inspections of common areas offices, classrooms, closets, restrooms, etc., as necessary. Monitors will be discretely placed in areas where infestations are most likely to occur. 2. When activity is observed, treatment will be rendered using chemical or nonchemical methods as required. Nonchemical methods include physically removing infestations (using vacuums where practical); removing webs, and installing monitors to check further pest activity. Chemical methods include residual spot treatments, baiting (in container, aerosol, and dust formations), crack and crevice, and other applications as required. These methods ensure that chemicals (if needed) are applied to the areas where insects breed/harbor, and virtually eliminate odors normally associated with pesticide applications. 3. When a rodenticide is used, it will be in bait station and stationed in an area inaccessible from students. The Executive Director of Facilities will be informed of its use.
