How PestSheet covers it in Montana
Before you complete a visit for a client in Montana, PestSheet checks that these fields are filled in:
- Applicator license or certification number
- EPA registration number
- Rate or dilution
- Application method
- Size of the area treated
- Target pest
- Areas or sites treated
- End time of the service
For exterior applications, it also asks for:
- Weather (wind, temperature)
Also:
- Reminds you to keep records at least 2 years.
- Export the records of any period as PDF or CSV for an inspection (Pro).
The client's name and address, the service date and start time, and the applicator's name are always recorded. The app uses the Admin. R. Mont. 4.10.207 template. It doesn't check items the app doesn't record (for example active ingredients or equipment); those remain your responsibility.
