Beginning on October 1, 2020, the NCWP office will be changing to Winter Hours.  We will be open Monday - Thursdays from 7am - 5pm.  We will be closed on Fridays.  These hours will remain in effect until April 30, 2021.


Aim for a chance of having less weeds next year by treating Russian Knapweed, Canada Thistle, Field Bindweed & Scotch Thistle Rosettes NOW!

The best time to treat these species is during the Fall when they are trying to send carbohydrates down to their large root systems.

Call our office at 472-5559 to discuss treatment options for Fall use.

Happy Fall Y'all !


Beginning May 11, 2020: 

The Natrona County Weed and Pest will be adjusting our policies to better provide our services to the residents of Natrona County.  We are open to the public by Appointment Only and will provide Curbside Pickup.  As our office is too small to allow for adequate social distancing, we ask that all residents CALL BEFORE coming to the office. This will allow us to address your questions and requests in advance to develop a treatment plan to fit your specific needs. This will also allow us to schedule an appointment time for your order pickup. When you arrive at our gate during your appointment time, please stop at the gate and call our office

(307) 472-5559 to notify us of your arrival.  We will bring your order of chemicals and/or equipment to the parking lot for Curbside Pickup. We wish you all a safe & healthy spring!
