The two technicians came and had us show them the places we had seen cockroaches and then told us what they would do to take care of them. They suggested either a follow up visit in 2 weeks or a month. He said there wasn’t much activity so he felt it was ok to wait a month. Then they said we had to leave for 4 hours, with our dog, until everything dried. We came back quite a bit later and everything was taken care of. We are happy with the results so far!
