Nisus DSV

The Virus

Q. What is COVID-19?
A. COVID-19 is the disease caused by SARS-CoV-2.

Q. What is SARS-CoV-2?
A. The virus has been named “Severe Acute Respiratory Syndrome Coronavirus 2” or “SARS-CoV-2” and
was identified in late 2019. It is a type of enveloped human coronavirus.

Q. What is the source of SARS-CoV-2?
A. This virus likely originated in bats prior to transmission to humans via direct contact with bats or via
contact with animals infected by bats in Asia.

Q. Is the virus food-borne?
A. At this time, the virus is believed to be transmitted only via person to person contact by touch or by
inhalation near an infected person or by contact with surfaces which harbor the virus.

Q. Do all infected people show symptoms?
A. No. Some people show symptoms, and some show no symptoms (asymptomatic). Those who show
no symptoms are particularly a concern in that they can spread the virus without knowing. The
incubation period is typically several days or longer.

Q. Do we expect the virus to die off with warm weather?
A. Nobody knows at this point. The CDC is hopeful that the virus will run the traditional cycle of dying off
in warm weather, but the concern remains that it may re-emerge with the next cool season.

Q. How can we stop the spread of COVID-19?
A. Follow guidelines of the Centers for Disease Control and Prevention (CDC) at

Q. Can the virus survive on surfaces?
A. At this time, virologists believe that a good estimate is that the virus can survive on plastic surfaces
for one day and hard non-porous surfaces such as metal for three days.

Applying Nisus DSV

Q. What exactly is Nisus DSV?
A. Nisus DSV is a disinfectant, sanitizer and virucide. It is a concentrate of four active ingredients
(quaternary ammonias) and is diluted before use. Nisus DSV concentrate contains the following active
Octyl Decyl Dimethyl Ammonium Chloride 1.65%
Didecyl Dimethyl Ammonium Chloride 0.825%
Dioctyl Dimethyl Ammonium Chloride 0.825%
Alkyl Dimethyl Benzyl Ammonium Chloride 2.200%

Q. “Human coronavirus” is on the label as a target organism. Since SARS-CoV-2 is a type of human
coronavirus, can we claim efficacy against SARS-CoV-2 virus, the cause of COVID-19?
A. SARS-CoV-2 is a new or novel virus. Only two categories of products may claim efficacy…those
products which are part of the emerging pathogens program and those products not part of the
program, but which EPA has deemed effective against SARS-CoV-2. Both categories of acceptable
products are found on List N, published by EPA. The base for Nisus DSV, 10324-80, was added to EPA’s
List N on 3/13/20. As a result, EPA has determined that Nisus DSV is effective against SARS-CoV-2, the
cause of COVID-19. EPA instructs applicators to follow the label instructions for (human) coronavirus.
The label rate is 2 oz. Nisus DSV per gallon of water with a minimum of a 10-minute contact time. A
thorough application is needed for success.

Q. Where is Nisus DSV found on EPA’s List N?
A. The products found on List N are the names that the registrants used to submit their application
originally for registration. Often, those names are place holders until registered and then a market name
is later added. For example, a product may be registered as XYZ-999 and when marketed, it might be
named Walt’s Super Duper Disinfectant. Unless the original name submitted for EPA registration was
then used as the market name, the List N name will not match the market name. To confirm that Nisus
DSV is on the list, simply search for 10324-80. That is the base and it is also found on the Nisus DSV
product label on each container. The registration number of Nisus DSV is 10324-80-64405. 64405 is the
Nisus EPA company number.

Q. Is any product labeled specifically for the control of SARS-CoV-2?
A. No. As of March 2020, no product is labeled specifically for SARS-CoV-2. The virus was only identified
in late December 2019, so no labels have that strain listed.

Q. Can diluted Nisus DSV be applied to hands to replace a hand sanitizer?
A. No. Nisus DSV is for surfaces only and is not for use on people or animals.

Q. What is the label rate other than for human coronavirus?
A. For most applications, the label rate is currently 1 to 2 fluid ounces per gallon of water with varying
contact times. Some applications require differing rates, so as always, read and follow the label.

Q. Nisus DSV has a DANGER signal word. Why is that?
A. If you look at the Precautionary Statements, note that this product, as with most concentrated quats,
can be harmful if splashed into the eyes. Once diluted, while care should be taken, the danger is
dramatically reduced.

Q. Is Nisus DSV a restricted use pesticide?
A. No. Nisus DSV is a general use pesticide.

Q. Do I need eye protection and gloves?
A. Read the label for instructions on personal protective equipment.

Q. Does Nisus DSV leave residual protection and when may it be reapplied?
A. Once the product dries, no residual should be expected. This is true of any “quat” product on hard
non-porous surfaces. There are no restrictions as to time interval to reapply.

Q. What is the difference between sanitizing and disinfection?
A. Sanitizing means to reduce the number of organisms to a level of no health concern. Disinfection is
killing 100% of organisms on a surface.

Q. If asked to provide disinfection services in a location where people with communicable diseases are
present or have been quarantined, what special precautions should the applicator take?
A. Guidance about communicable disease exposure and precautions are determined by the medical care
facility. If the service location is not a managed medical facility, the local health department should be
contacted for guidance.

Q. Can I use a concentration stronger than the label rate?
A. It is a violation of federal and state law to use a concentration stronger than the label permits for that

Q. Can I use less than the label rate?
A. For an antimicrobial, you should always use the label rate and not less.

Q. Can I fog the interior of a customer’s building with Nisus DSV?
A. The label permits fogging in certain situations, but the product will be more effective if liquid is
applied directly to surfaces. Note that “fogging” on the label is a wet mist and not thermal or other
traditional “fogging” application. The disadvantage of “fogging” is that the droplets will settle on
horizontal surfaces by gravity and not reach under surfaces such as beneath handrails. Also most foggers
cannot leave a surface wet enough for the 10 minutes required for disinfection.

Q. Will Nisus DSV work on soft surfaces such as pillows?
A. Nisus DSV is formulated for hard non-porous surfaces. Some surfaces such as carpets are on the label
but application to a porous surface will not be as effective, which is why cloth, textiles, clothing, etc., are
not on the label as a site.

Q. How is Nisus DSV applied?
A. It can be applied via mop and bucket, sprayers, sponge, soaking, and in limited uses, by fogging
(defined as wet misting). See the label for full details.

Q. Is rinsing required?
A. Rinsing is required after treating food contact surfaces for sanitizing for 30 seconds or disinfecting for
10 minutes.

Q. After treating, how long should a customer remain out of the area?
A. Unless a specific use on the label states otherwise, customers do not need to be out of the area for
any given time while Nisus DSV is being applied. Some states require customers (commonly in schools)
to remain out of the area for a certain period. This will vary by state. Customers should not touch
surfaces until dry.

Q. Is a special state license required for using Nisus DSV by professionals?
A. Nisus DSV does list flies as a target pest on the label so for those applications, the general pest control
certification will be adequate for that purpose. For sanitizing and disinfection, most states permit use
under the general pest control category. Some states have a special category in the same category as
mold control. Always check state requirements for company certification. Certification does not apply to
use by homeowners.

Q. Does this mean that professional applicators must be certified?
A. Usually not. This is the category for at least one employee to hold. State requirements may vary so
always check state regulations.

Q. Does my insurance cover sanitizing and disinfection?
A. Insurance policies vary and the coverage that the company has chosen will vary dramatically. For any
questions about coverage, contact your insurer.

Q. Can Nisus DSV be applied to soil?
A. Nisus DSV is for hard, non-porous surfaces and some soft surfaces. Nisus DSV should not be applied to

Q. Does Nisus DSV have a chemical odor?
A. Nisus DSV has a pleasant fresh citrus fragrance with no chemical odor.

Q. What is the shelf life of Nisus DSV?
A. The concentrate should be stored in cool and dry place. The product is stable for over a year. Diluted
Nisus DSV is also stable but it is always best to mix only what is needed for an application in order to
avoid having to label and store a diluted product.
