Have bed bugs? Call Viking right away!!! We picked up bed bugs on a vacation in Massachusetts. After trying to get rid of them ourselves didn't work we decided to call professionals. I'm glad I called Viking! All of the people we have dealt with have been great. The first person I spoke to clearly went over the process and cost. Then onto scheduling which was a breeze. All of the technicians showed sympathy for what we were going through and listened to and took care of our concerns. They give a 60 day warranty after the second service. My wife got bit again after the second service and they didn't hesitate to send over a tech to take care of it. We have been bite free for a couple of weeks now. I can't recommend them more for bed bug service!
