FMPs and Posting

​A written, site-specific fumigation management plan (FMP) is required before fumigation begins. The FMP is a written description of the steps designed to ensure a safe, legal, and effective fumigation of burrowing rodents. The Qualified Applicator supervising the application must verify the accuracy of the FMP.

You can find the form on the DPR website. Some counties may allow the use of alternative forms.

When products containing the active ingredient aluminum phosphide are used as part of a fumigation management plan in athletic field and parks, or in outdoor areas frequented by people, the applicator must post a sign at entrances to the treated site. Signs should contain:
  • The signal word DANGER/PELIGRO
  • Skull and crossbones symbol
  • The words: DO NOT ENTER/NO ENTRE, FIELD NOT FOR USE (only necessary for athletic fields and parks)
  • The name and EPA registration number of the fumigant
  • A 24-hour emergency response number

​Signs may be removed 2 days after the final treatment.
