All pesticides used by school districts must be registered with the United States Environmental Protection Agency (EPA) and the department, with the exception of those pesticides that have been exempted from registration by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Section 25(b). All pesticides used by school districts must also bear a label as required by FIFRA and Chapter 76 of the Texas Agriculture Code. Pesticides intended and labeled for use on humans are exempt from this section. Pesticide use must also meet the following requirements:
  (1) Pest control signs shall be posted at least 48 hours prior to a pesticide application inside school district buildings, including residential properties, as provided for under §7.148 of this chapter (relating to Responsibilities of Unlicensed Persons for Posting and Notification).
  (2) For outdoor applications made on school district grounds, including residential properties, the treated area must be identified at all entry points with a sign, or must be secured using a locking device, a fence or other practical barrier such as commercially available barrier caution tape, or periodically monitored to keep students out of the treated area until the allowed reentry time.
  (3) Pesticides used on school district property shall be mixed outside of student occupied areas of buildings and grounds.
  (4) The use of non-pesticide control measures, non-pesticide monitoring tools and mechanical devices, such as glue boards and traps as permitted in accordance with Division 7 of this subchapter (relating to Integrated Pest Management Program for School Districts), are exempt from posting requirements. The use of non-pesticide tools and devices by unlicensed school district personnel, for monitoring purposes, shall be permitted. Monitoring by unlicensed school district personnel shall be done only as directed, under the supervision of the IPM Coordinator.
  (5) Pesticide applications shall not be made to outdoor school grounds if such an application will expose students to physical drift of pesticide spray particles. Reasonable preventive measures shall be taken to avoid the potential of drift to occur.
  (6) School districts are allowed to apply the following pesticides to control pests, rodents, insects and weeds at school buildings, grounds, or other facilities in accordance with the approval for use and restrictions listed for each category:

        (II) it consists of the active ingredient boric acid; disodium octoborate tetrahydrate or related boron compounds; silica gel; diatomaceous earth; or belongs to the class of pesticides that are insect growth regulators; microbe-based insecticides; botanical insecticides containing no more than 5% synergist (and does not include synthetic pyrethroids); biological (living) control agents; pesticidal soaps; natural or synthetic horticultural oils; or insect and rodent baits in tamper-resistant containers; or for crack-and-crevice use only;

Reentry into the treated area is permitted as soon as the application is complete, the pesticide spray has dried, or the reentry interval specified on the pesticide label has expired, whichever interval is longer.
        (II) Green Category pesticides may be applied outdoors if students are not present within ten (10) feet of the application site at the time of treatment. Students are allowed reentry into the treated area as soon as the application is complete, the pesticide spray has dried or the reentry interval specified on the pesticide label has expired, whichever interval is longer.

        (III) The treated area must be clearly posted at all entry points with a sign, or secured using a locking device, a fence or other practical barrier such as commercially available barrier caution tape, or periodically monitored to keep students out of the treated area until the allowed reentry time.
