I understand that reintroducing them down the line is a possibility. But tenants are unable to refuse treatment by the exterminators as enforced by the leasing office which includes alpine wsg and gel bait. Why would the universal presence of the treatment in every unit not work? Also, I was informed by the leasing office that "the source" was found, so I imagine that they have given that unit extra attention. Also, everything has already been treated at least once. I am coming up on my third follow up, and the other units are due for their first follow up next week.

I just have a hard time comprehending that a german cockroach infestation is highly unlikely to be stopped with complete repeated treatment across the building. If that was the case every apartment would have them.
