What gets asked
The desk answers the same dozen questions most weeks. Here they are with the answers we send, and the container label as the final word on all of them.
Asked at the desk
What is the mixing rate for the concentrate?
One fluid ounce per gallon of water, and the rate stays the same at any infestation level. A gallon of finished spray covers about 1,500 square feet. The pint bottle mixes sixteen gallons; the 1 oz bottles are one gallon each, premeasured.
The adults are still walking around a week after treatment. Did it fail?
No. The regulator works on the immature insects in the harborage, and the adults you can see were never the target. They age out over the following weeks while the generation behind them stalls short of breeding form. Watch the monitor count, not the floor.
How long does one application keep working?
Up to 120 days in a treated crack or void that stays dry and undisturbed. Surfaces that get scrubbed daily lose the material with the scrubbing, which is one reason the deep seams are the right placement.
How often do point source stations get replaced?
The label sets the service interval. Each disc has a spot to write the install date, and writing it turns replacement into arithmetic instead of memory.
Can the concentrate share a tank with another product?
It is built to, provided the other label agrees. Read both, and jar a small amount of the intended mix first: separation or clouding shows in a jar before it costs you a tank.
Which product handles drain flies?
The aerosol. The foam lays into the drain collar and coats the film where the larvae feed. Foam on a standing schedule, because the film grows back weekly.
When is Complete the right choice over plain Gentrol?
When adults are visible now and the room cannot wait for the generation to turn over. Complete pairs the same regulator with an ingredient that works on contact, so the standing insects get an answer the same day.
Where am I allowed to apply these products?
The container label lists every permitted site, from residential kitchens to food handling establishments, along with the method for each. It is the deciding document, and reading it in full before application is part of the label instruction itself.
