I have using Burr Pest Control for about 2.5 years. I'm signed up for their annual plan (Healthy Home Platinum Service) meaning they come out 4 times per year. Yes even in the winter. No issues with the product they use, seems to work very well. The Technician (Mike) they send out does a great job and ask questions regarding pests (bees) and listens to my responses making sure he addresses any concerns I have. This interaction is mission critical and ensures I continue to use Burr Pest Control.
