Considering that CutandRun and I both live in the Illinois Metro East across from St. Louis and the number is a 618 area code, it must be something local. A google shows that it's Healthy Home Pest Control and Services from Belleville Illinois. I've never had contact with this company so I'm going to block them.
They are in the same area code. I was also able to do a google search on them. They just called again today. I've never done business with them in the past.
This is the number of Healthy Home Pest Control. Used them in the past but cancelled the service, but just had a missed call from that number. I had no problem with the service. Just decided I could no longer afford it. They might be calling to try & get me back as a customer...don't know. They didn't leave a message.
