Every member of the Halt Pest Control team is a dedicated pest control professional. We’ve been delivering pest control solutions with you in mind for nearly 30 years. We’re also a certified QualityPro and QualityPro Green company. That means that every Halt employee has undergone a rigorous criminal and driving background check, is up to date in their certifications and training, and that Halt Pest Control maintains a drug-free workplace.

All that experience and background checking is great, but we also understand that when someone comes into your home or onto your property to provide a service, having a face to connect to a name and knowing a little bit more about them can really ease your mind.

Meet the Halt Pest Control Team!

Rob McMaster


In 1990, Rob had a vision. He wanted to create a pest control company like none other. He founded Halt Pest Control with the idea of helping people solve their pest problems with a solution that would fit their unique environment, rather than delivering a single pest control service and never seeing that person again. He and the Halt team have been doing just that ever since. Rob loves connecting with people and the challenges of leading a team and growing the business. He particularly enjoys watching the people on the Halt team grow into the Halt way of serving customers, learning from each other and expanding their professional skills.

Back in the late 80's Rob and his wife were in search of a great place to raise a family. That’s when they came to the Portland area (from that state just south of Oregon) and have loved it here ever since. Rob’s interests cover a lot of areas. He enjoys the outdoors and is an avid fisherman and hunter and he also enjoys traveling and spending time in the garden. He and his wife also spend a lot of time with their two daughters and their horses. Rob holds two Bachelor’s Degrees from the University of the Pacific.
