The fourteen items on a Washington record

Record the customer's full name and full address, where the pesticide went, the date and the start and stop times, each product's label name and EPA registration number, the total amount, the amount per 1,000 square feet or other measure, the concentration, the pests targeted, the specific site and the area treated.

Add the apparatus license plate number, the licensed applicator's full name, license number, complete address and phone, the full name of everyone who made the application, and the firm's full name and address. Outdoor work also needs wind direction, estimated speed and temperature; baits in stations and indoor applications do not.

Ounces, gallons and fumigations

Pest control operator records give the amount to the nearest ounce of product or nearest gallon of spray for each site. Fumigation records give pounds of gas per 1,000 cubic feet, the temperature and how long the exposure lasted.

Same day, seven years, 250 dollars a mistake

Finish the record the same day you apply, keep it seven years, and give a customer the season's records for their property when they ask in writing. Other requests are answered within seventy-two hours, and immediately for health care staff treating a suspected poisoning. The department assesses a 250 dollar penalty for each failure to record required information.

Landscape markers and equipment

A landscape application at a home gets a marker at the usual entry point (or at the spot for a small spot treatment; none for a fenced backyard), at least four by five inches, with the required headline and footer, your company name and phone. It stays up at least twenty-four hours, or longer if the label's restricted entry interval says so. Keep the apparatus clean and in repair and label every mixture container you carry.

From the truck to a finished Washington record

Note your start and stop times, the truck's plate, each product with its amount and mix, which pests it was for, and the wind and temperature for outside work. ReportDraft puts every one of the fourteen items in its place and leaves weather blank for indoor and bait station work.

Common mistakes

  • No stop time on the record.
  • Leaving off the apparatus license plate number.
  • Recording the customer's name but not their full address.
  • No wind or temperature for an exterior perimeter spray.
  • Finishing the paperwork the next morning instead of the same day.
