Glueboards are probably as old as cockroaches themselves (well, nearly). They are an under-valued tool in the pest control industry. When a pest control service technician is on site, what they get is a picture in time; they will base their decisions on what they are seeing, but a glueboard works 24 hours a day. It has a strong work ethic. When the pest control service technician returns to follow up, they can see cockroach activity based on what has been captured on the glueboard. It is a very powerful tool.
