How PestSheet covers it in Iowa
Before you complete a visit for a client in Iowa, PestSheet checks that these fields are filled in:
- Applicator license or certification number
- Business license number
- EPA registration number
- Amount applied
- Rate or dilution
- Size of the area treated
- End time of the service
If you apply a restricted use product (RUP), it also checks:
- Areas or sites treated
For exterior applications, it also asks for:
- Weather (wind, temperature)
Also:
- Reminds you to keep records at least 3 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 Iowa Admin. Code 21—45.26(3) template. It doesn't check items the app doesn't record (for example active ingredients or equipment); those remain your responsibility.
