I used Monitor to get rid of an ant issue that had baffled 3 previous exterminators over the years. The pricing was extremely reasonable. Ants are tricky, but the bulk of them were wiped out the first visit. They have had to come back twice so far to follow up with better results each time and at no additional cost to follow up. They are extremely thorough and professional and basically once a year. You can’t beat it! I highly recommend them.
