About us

The Bug Doctor is more than a pest control company — we’re a family tradition proudly serving Denver and surrounding communities for decades.

Our story

Our roots began in the late 1990s with Richard “Big Dale” Litreal, who built Bug Doctor with the help of his wife, Kay, and their son, Christopher "Dale". Together, they grew the business on simple values: honest work, quick response times, and treating customers like neighbors. For over twenty years, Big Dale became a familiar and trusted face in the community, known for his friendly personality and dedication to getting the job done right.

After Big Dale’s passing in 2021, the business remained in the family and continued serving long-time customers with the same care and commitment. In October 2025, Bug Doctor LLC entered a new chapter when ownership transitioned to his brother-in-law, Christopher Caldwell. Alongside his partner, Natasha, and other family members, Christopher is focused on honoring the company’s legacy while modernizing operations and rebuilding a strong local presence across Colorado.

Today, Bug Doctor LLC proudly serves over two hundred recurring residential and commercial clients. While our tools and technology continue to evolve, our approach has stayed the same: personal service, clear communication, and long-term relationships built on trust. When you call Bug Doctor, you’re not calling a big corporation, you’re calling a family that truly cares about your home, your business, and your peace of mind.
