About Best Pest Control Founded in 1998 by Hank Thompson, an expert exterminator with over 12 years of experience, Best Pest Control proudly serves our neighbors in Casper, Douglas, Wheatland, Rawlins and Rock Springs. As a local company, family-owned and operated, we have the experience and insight needed to take on Wyoming’s most unwanted bugs, rodents and pests. Unlike big national chains, we know the land, the climate and what creeps and crawls in this area. We’ve built a reputation that you can trust by helping our community with the very best inspections, pest control treatments and preventative measures.
