Nora Pasta 25: a pasta bait against rats and mice

Rats and mice can quickly become problematic in agricultural buildings, farms, storage areas, outbuildings, or homes. Besides the damage they cause to facilities and food reserves, their presence usually requires a structured intervention to prevent the population from continuing to grow.

Nora Pasta 25 by Armosa is a rodenticide specially formulated to combat two commonly encountered species:

• the house mouse (Mus musculus);
• the brown rat (Rattus norvegicus).

The product is intended for use indoors and outdoors around buildings, in accordance with the usage conditions listed on its label.

It is available in the form of a ready-to-use paste, packaged in individual portions of about 10 g wrapped in filter paper.

A paste designed to be attractive to rodents

In a rat or mouse control program, the attractiveness of the bait plays an important role, especially when pests already have many food sources.

Nora Pasta 25 benefits from a formulation specially designed to be attractive to rodents, even in the presence of other foods.

Its presentation as a paste is particularly suited to environments where rodents have access to grains, animal feed, or other food resources.

To optimize bait acceptance, it is recommended to remove as much as possible the easily accessible competing sources, such as spilled grains and food waste.

Difénacoum 25 ppm: second-generation anticoagulant

The active ingredient of Nora Pasta 25 is difénacoum, present at a concentration of 0.0025%, or 25 ppm.

Difénacoum belongs to the family of second-generation anticoagulants. Its mechanism of action is based on its role as a vitamin K antagonist, essential for the normal process of blood coagulation.

The safety data sheet confirms the presence of 0.0025% difénacoum in the formulation.

This anticoagulant action is delayed. Therefore, the effects are not immediately associated by the rodent with the consumption of the bait.

Presence of Bitrex

Nora Pasta 25 also contains Bitrex, an extremely bitter denatonium benzoate.

Its incorporation provides an additional safety measure intended to make the product particularly unpleasant to taste for humans.

The presence of Bitrex does not, however, exempt users from respecting the precautions related to rodenticides: the product must remain inaccessible to children, pets, livestock, birds, and other non-target species.

Pre-dosed sachets of 10 g

Nora Pasta 25 is packaged in portions of about 10 g wrapped in filter paper.

This presentation facilitates the preparation of bait stations and allows easy calculation of the required amount of product.

The sachets containing the bait must not be opened. They should be placed as is in secure bait stations.

Two packaging options available

Nora Pasta 25 – 15 x 10 g

The 15 x 10 g packaging, or 150 g of product, is a practical solution for more limited needs.

The 15 pre-dosed portions allow for easy distribution of the bait in appropriate stations depending on the targeted pest.

Packaging: 150 g
Presentation: 15 sachets of 10 g
Active ingredient: difénacoum 25 ppm

This format is particularly suitable when the number of required bait points remains limited.

Nora Pasta 25 – 3 kg bucket

The 3 kg bucket is intended for larger needs and sites requiring more bait stations.

It is particularly useful for agricultural buildings, livestock farms, warehouses, outbuildings, and other sites where a larger rodent population must be controlled.

The Armosa technical sheet specifically identifies the 3 kg bucket under the reference RD-DIF-21012.

Packaging: 3 kg
Presentation: paste in pre-dosed sachets of 10 g
Active ingredient: difénacoum 25 ppm

Against which rodents should Nora Pasta 25 be used?

House mouse – Mus musculus

The house mouse can settle in very small spaces and frequently moves near food sources.

To increase the chances of consumption, bait stations should be placed as close as possible to areas where their activity has been observed.

Brown rat – Rattus norvegicus

The brown rat, also known as the Norway rat, is commonly found in agricultural operations, livestock buildings, warehouses, and other environments providing food, water, and shelter.

Nora Pasta 25 is officially intended for these two species.

Where to install the bait stations?

Before starting the treatment, it is important to identify the areas actually frequented by rodents.

Look for signs of passage, droppings, burrows, damage, and other indicators to determine their usual pathways.

The stations can be installed:

• near nesting sites;
• along the paths used by the rodents;
• near areas where they usually feed;
• in or near accessible hollow structures;
• in immediate proximity to places where recent activity has been observed.

Bait stations must be secured and, when possible, fixed to the ground or a structure to prevent movement.

Dosage of Nora Pasta 25

The dosage depends on the targeted rodent.

For mice

For the house mouse (Mus musculus):

30 g of bait per station, i.e., 3 sachets of 10 g.

When multiple stations are necessary, a minimum distance of 2 meters should separate two bait stations.

For brown rats

For the brown rat (Rattus norvegicus):

100 g of bait per station, i.e., 10 sachets of 10 g.

When multiple stations are necessary, a minimum distance of 5 meters should separate two stations.

The total number of stations should be adapted to the extent and severity of the infestation.

Regularly check the baits

A rodenticide treatment requires monitoring.

At the start of the treatment, Armosa recommends inspecting the stations:

Mice: every 2 to 3 days

Rats: every 5 to 7 days

Consumed or damaged baits must be replaced.

Subsequently, the stations should be checked at least once a week to verify consumption and the condition of the setup, and to refill the stations when necessary.

Rodent carcasses should also be searched for and removed regularly to reduce the risk of secondary poisoning of non-target animals.

Use outside of buildings

Nora Pasta 25 can also be used outside around buildings, in compliance with the product's authorization conditions.

In this case, the baits must be protected from weather conditions, especially rain and snow.

Stations should be placed in locations not at risk of flooding. Any bait degraded by water or contaminated must be replaced.

Outdoor baiting points should also be covered and positioned to limit exposure to non-target species as much as possible.

Armosa documentation classifies Nora Pasta 25 as a biocide TP14 rodenticide.

A rodent control associated with preventive measures

The use of a rodenticide will be more relevant when it is part of a comprehensive pest control strategy.

Before and during treatment, it is recommended to limit access to food, remove spilled cereals and food waste, search for entry points into buildings, and, when possible, seal holes and passages allowing rodents to enter the premises.

Armosa also recommends incorporating the product into an approach that includes hygiene measures and, when possible, physical control methods. 

Nora Pasta 25 should not be used as a permanent bait simply to prevent the arrival of rodents or to monitor their presence. If activity persists after the treatment period, the situation should be reassessed to determine the cause. 

Precautions for use

Nora Pasta 25 contains an anticoagulant substance and must be handled with care.

Keep the product out of reach of children, birds, pets, livestock, and other non-target animals. The stations should also be placed away from food and drinks, including those intended for animals. 

Store the product in its original, properly closed packaging, in a dry, cool, well-ventilated place protected from sunlight. 

Do not eat, drink, or smoke while handling and wash hands thoroughly after use.

In case of accidental ingestion by a pet, contact a veterinarian. In case of ingestion by a person, consult a doctor immediately and present the packaging or label. Since difenacoum is an anticoagulant, some signs of intoxication may appear with delay. 

Use biocides with caution. Before any use, read the label and product information.

Nora Pasta 25: two formats according to the importance of the treatment

With its pre-dosed 10 g paste sachets, Nora Pasta 25 allows for easy implementation of targeted treatment against brown rats and mice.

The 15 x 10 g packaging meets more limited needs, while the 3 kg bucket offers an appropriate quantity for treatments requiring more bait stations.

Its formulation with difenacoum 25 ppm, its attractive paste presentation, and simple dosing make it a solution for rodent control in and around buildings, provided that the conditions of use and safety measures on the label are strictly followed.
