Sam is always so considerate and timely! He made sure we didn’t have any pets that needed to go out before treatment since they wouldn’t be able to for 2 hours while it dries! Would recommend him to anyone! We haven’t had a mouse since his first visit!

I was worried about having bed bugs which is why I wanted an inspection. I've apparently had an unexplained allergic reaction to something. Chris was professional, thorough and pleasant. He reassured me that there was no infestation. The peace of mind Chris provided was worth the time and money. Thank you.

We having been using 603 Pest for over a year now. Decided to do the quarterly maintenance plan. They automatically schedule the appointment every 3 months but changing it is no big deal if needed. We also did the monthly mosquitoe/tick spraying last summer. Every single person that has come for the services has been super nice, they explain what they are doing, and they make sure to ask if we have any additional questions or concerns. Super happy with the effectiveness of services and the excellent customer service.

Dan was great. We did a walk through of the area affected and came up with a game plan. Very professional company from inquiry to service! Thanks 603.

Absolutely phenomenal service. From the office to the technician, my wife and I were very impressed. We had a field mouse problem in our basement that I couldn't quite get to the bottom of, and I'm so glad I finally called 603 Pest and handed it off to them. After their first visit I noticed a complete stop in activity (after catching one leftover mouse that was already likely in our home). I set a trap again in our highest-traffic space and never caught another. Problem solved.

We had an issue with Boxelder Bugs, it had progressed and we had tried everything to get rid of them. 603 Pest came and saved the day and the house! The process was smooth and thorough. Thank you so much, we saw an improvement the next day! The 30 day warranty gave a lot of relief incase we saw them come back.

Chris came out for mice and to set traps, closed up places of entry, and sprayed for ants. He was prompt, polite, and did a great job of explaining what he was doing and what we should look for in the future. Within two days we had caught 6 mice. Dan came out for a follow up two weeks later to set more traps. Dan was also great and happy to answer questions and educate us on rodents. We are very happy with the results. Price was higher than I had initially hoped, but it was in-line with other pest control companies that I had looked into, so it seems like a fair market price. Will call again if we have more pest issues in the future.

We had an emergency situation with yellow jackets in my sons room and they were wonderful! Both people I spoke with on the phone were friendly, helpful and professional. They had to rearrange some things to be able to help us, they called back within minutes and had someone out to us in about an hour. Dan came and was so thorough. treated the issue effectively, and was even nice enough to knock another nest on our porch that he noticed before he left. Highly recommend!

Over the past few years, my wife and I have experienced recurring problems with yellow jackets and wasps taking up residence on our property. After receiving some painful stings, we contacted 603 Pest Control Services for help. They scheduled an appointment the next day. Sam, the technician assigned, arrived on time, was very personable, knowledgeable and professional during the service. He explained what the service entailed, did a complete inspection around our home, kept us apprised as the work progressed, eliminated a fist-sized wasp nest under our deck steps, and treated other areas around our home to prevent further nesting. Jen and Niki from the office staff were very helpful scheduling the service as well as answering our many questions. Their service fees are reasonable and their technicians are trained and properly equipped to perform the service. We’ve used other pest control services in the past but none were as responsive as 603 Pest Services. We were very impressed with the service received. Thank you Sam, Jen and Niki!!!
