Mapping out the right fumigation procedure for your infestation will be paramount in getting rid of the pests for good. To do this, you'll need to consider a few things before employing the use of chemicals. These are as follows:
• Conducting a suitability test
• Holding a conference prior to fumigation
• Applying the fumigation
• Mitigating the risk to persons after its release
Have you received a written statement from the certified fumigation technician that the premises are suitable for fumigation?
Conference before fumigation
Did you attend the pre-fumigation conference conducted by the certified fumigation technician?
Did you get a copy of the registered label for the fumigant to be used?
Has the certified fumigation technician identified the rooms or containers to be fumigated?

Has the responsible person indicated the duration of transport?
Have safety precautions been discussed by the certified fumigation supervisor, including symptoms of fumigation exposure, first aid measures, instruction of two employees in the use of respirators and phosphine detection devices, and must rooms or containers that will be fumigated be closed during the entire transport period?
