“We have been using Custom West Pest Control for almost a year now.

We were looking for a company that could provide a preventative maintenance program on a regular basis, as well as responding to any occurrences that popped up in an efficient manner. We made the first call and they had a technician to us the same day, within one hour. Since then they have provided prompt, reliable service whenever we need it, and the price is very competitive. Their technicians are always friendly and discreet, and we trust that the job will always be done right!” Kim Sawyer

General Manager, Wingate of Missoula

“Ian and Ben arrived on time. The contracted service was performed as bid with all due consideration to the aesthetics of the timberframe and rock work. The work area was left neat and tidy. Ian and Ben subsequently explained the process and follow-up. Both technicians were polite and congenial; a real credit to the company!” Dan Burger
