Where point source discs go

What the station actually is

A point source station is a small disc with an adhesive back and hydroprene inside. Press the tab, stick it to a surface, and it releases the active into the surrounding air over time. There is no spray, no wet surface and nothing to schedule around.

The box holds twenty stations, and each one covers roughly 75 square feet. That number reads small until you remember it describes cabinet interiors and voids, not open rooms.

Enclosed volume is the whole idea

The disc works by keeping the active concentrated in a contained space. Inside a closed cabinet, the vapor works into the hinges, corners and shelf seams where nymphs harbor. In an open room, the same output thins into the air volume and does much less.

So the question for every disc is not where is the floor space, it is where is the box. Cabinets, drawers, appliance housings, electrical rooms, the void under a booth seat. If it has walls and a door, it is a candidate.

The placements that come up on every job

Under-sink cabinets earn a disc almost by default: warm, damp, plumbing penetrations, and a door that stays shut. The cabinet over the coffee station in an office kitchen is another regular, along with the base cabinet next to the dishwasher where the heat gathers.

Stick the disc high on an inside wall rather than flat on the shelf, where it catches spills and gets buried under bottles. Each disc has a spot to write the date, and writing it is the difference between a program and a scatter of old plastic.

When a disc beats a spray

Some spaces do not want a wet application. Cabinets full of dishes, electrical panels, server closets, the drawer where the menus live. A disc treats those spaces without touching what is stored in them, and it does it without a second visit.

The other case is quiet accounts: offices, nursing floors, anywhere a can hissing behind the counter draws attention. A disc goes in during a normal walk-through and nobody knows the visit happened.

Discs are one leg of the program

A station holds a cabinet. It does not reach the wall void behind the cabinet or the seam under the baseboard across the room, and it was never meant to. Those belong to the aerosol and the tank.

The pattern that works on real accounts: aerosol into the cracks at the start, discs into the enclosed spaces for the long middle, and the label sets the date the discs come out and fresh ones go in.
