I chose Ja-Roy because they were referred to us when we closed on our home. They are a small business with lots of personal attention. We have met two of the employees thus far. Our exterminator calls to remind us of our approaching due date. He never annoys us, just reminds us.
For the most part, I don't see any bugs after they spray. However, after one trip I still saw a lot of bugs. But the rest of the times they came, I didn't see any bugs after they sprayed. I am not sure why I saw bugs that one time.
They offer different plans. They can come monthly, bi-monthly, quarterly, etc....depending on your needs. They are decently priced, no better or worse than other companies.
