Keeping a commercial kitchen clear

A kitchen is really four rooms

Treating a commercial kitchen as one space is how programs fall apart. It is a wet room around the dish line and drains, a hot room along the cook line, a dry room in storage, and a public room out front. Each one breeds a different insect and takes the material differently.

The line splits the same way. The tank mix walks the perimeter, the aerosol works the seams and drains, the discs hold the enclosed spaces, and Complete answers whatever is visible when the lights come on.

The drains are the standing appointment

Drain flies and fruit flies are not wandering in from outside. They are breeding in the film inside the floor drains, and every week that film grows back. The aerosol foam laid into the drain collar reaches the larvae feeding in that layer before they reach the air.

Foam the drains on a schedule, not on complaint. A drain that gets attention only after the flies show is a drain that is always a week behind.

Where the tank mix goes

The concentrate at one ounce per gallon covers the structural side of the account: baseboards, the wall behind the cook line, mop sink surrounds, the voids where conduit and plumbing come through. This is the pass that puts the regulator into the building itself.

Time it for the closed hours and let the label decide which surfaces are in bounds. Food contact surfaces are their own category with their own rules, and the label text is the deciding document, not habit.

Discs in the spaces that stay shut

A commercial kitchen is full of closed volumes nobody sprays: the cabinet under the front counter, the housing of the dish machine, dry storage shelving, the electrical room. A point source disc in each one keeps the active working there between visits.

Date every disc as it goes in. On a monthly account the discs become the memory of the program, and a written date settles every question about when the swap is due.

What to tell the staff

The kitchen crew will judge the program by the adults they see, and adults are the last thing to change. Tell them the order in advance: the drains quiet first, then the small flies thin out, then the roach sightings fade as the old adults age out with nothing behind them.

Give them the glue board count instead of the anecdote. A monitor log falling month over month is what progress looks like on paper, and it is the story a health inspector reads fastest too.
