“Who is the best pest control company in Billings, Montana?”

No one company is clearly "the best." Reviews are spread across several sites and none agree. These local names come up the most and are good places to start:

Local companies that come up often

• Best Pest Control (the business is actually called that). It's at 711 Central Ave STE 106, Billings, MT 59102 and has a 4.8 star rating with 54 reviews on Birdeye. That's the most reviews I found for any one local company. Reviews aren't all positive, though: one MapQuest reviewer said the company "no-showed and did not call for the second treatment."
• Summit Pest Management, Beeman Pest Solutions, Action Pest Control and Armstrong Pest Control of Montana all show up on Yelp's Billings top-10 lists. The full list also includes Kodiak Pest Control, Beeman Pest Solutions, Summit Pest Management, Action Pest Control, Armstrong Pest Control of Montana, Best Pest Control, Orkin, A-1 Pest Control, Montana Bug Hunters. Several of these have only one Yelp review each, so those ratings don't tell you much.
• Montana Bug Hunters describes itself as locally owned and committed to quality service.

National chains

Today's Homeowner rates Terminix 4.8/5 as its top pick, followed by Orkin 4.7/5. These ratings are for the companies nationwide, not the Billings branches.

How to choose

Get quotes from two or three companies, such as Best Pest Control, Beeman and Summit. Check that each one is licensed with the Montana Department of Agriculture and covers your specific pest. For example, Billings often has problems with spiders, mice and wasps. Also ask whether they'll come back between scheduled treatments at no extra cost.
