More than a decade ago, we were on a mission to offer a level of pest control service our area hasn't seen before. Fifteen years later, we're proud to say that we're doing it. With the most 5-star reviews of any local company, our team of local experts strive daily to do better to ensure our customer satisfaction.


We're proud to have more 5-star reviews than any other local pest control company. Once you're a customer, you're part of our family and we take that seriously. You will find that your local technician quickly becomes an extended family member to yours too. Our goal at Pfitzer Pest Control is to take the stress and strain out of your life, whether it's at your home, in business, or on your farm and ranch. Our responsive and friendly office staff are always available to answer questions between services (or to share a laugh)! We love what we do and it shows!


It all began in the fall of 2009, with a young man and a dream – to build a future for himself and his soon-to-be wife. Although our hero, Garret, didn’t always envision himself as “the bug guy”, he found that after working in the industry for a handful of years already, it allowed him to do what he loved most…to help people.

Upon entering holy matrimony in 2010, Garret and his bride, Karen, used their very opposite skillsets to grow the business. By this time, Garret had become quite the bug scholar and was the first line of defense between the bugs and his beloved customers. Karen, on the other hand, had no experience with bugs but had several years of sales and marketing experience and a MBA burning a hole in her pocket. They shared a passion for people and a sense of pride in their work.

Together, they grew their business to five locations throughout South Dakota and Wyoming. They strive to support each of the communities to which they serve by joining the local Chamber of Commerce, giving back to the communities and spending as much time at local events as possible!

Today, they are supported by a team of amazing and caring technicians and an office crew committed to making each and every customer experience top notch.
