Strong 25: A Multi-Cereal Bait Against Rats and Mice

The presence of rats or mice in a farm, agricultural operation, warehouse, outbuilding, or near buildings can quickly become problematic.

Strong 25 by Armosa has been developed to combat:

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

Its uniqueness lies in its multi-cereal formulation composed of a mix of three grains, designed to enhance the bait's attractiveness to rodents, even in environments where other food sources are available. Armosa's documentation presents it as a particularly attractive ready-to-use bait.

A Particularly Attractive Multi-Cereal Formulation

Unlike bait in paste or block form, Strong 25 is based on a cereal formulation, a naturally sought-after food for many rodents.

The mix of three grains makes it suitable as bait, especially for agricultural environments, livestock buildings, storage areas, and outbuildings.

To improve treatment efficiency, it is recommended to limit as much as possible the competing food sources accessible to rodents: spilled grains, animal feed, food waste, or other easily available commodities.

Brodifacoum 25 ppm: A Second-Generation Anticoagulant

Strong 25 contains brodifacoum at a concentration of 0.0025%, or 25 ppm.

This active substance belongs to the family of second-generation anticoagulants. Its mechanism of action is based on an antagonistic effect on vitamin K, essential for the normal process of blood coagulation.

The safety data sheet confirms a concentration of 0.0025% brodifacoum in the product.

Strong 25 also contains Bitrex, a bittering agent intended to reduce the risk of accidental ingestion by humans.

Two Packaging Options to Suit Your Needs

Strong 25 – 6 x 25 g

The 6 x 25 g packaging represents a total of 150 g of bait.

The pre-dosed portions facilitate the implementation of the treatment and allow precise distribution of the bait between different stations.

Packaging: 150 g
Presentation: 6 sachets of 25 g
Formulation: multi-cereal mix
Active substance: brodifacoum 25 ppm

This small package is particularly practical for treatments requiring only a few bait stations.

The sachets containing the bait should not be opened during use.

Strong 25 – Bucket of 3 kg

For larger needs, Strong 25 is also available in a bucket of 3 kg.

Unlike the sachet packaging, the product is offered here in bulk cereals.

This presentation allows for easier adaptation of the amount deposited in each station depending on the target pest and is particularly suitable for agricultural operations, livestock, warehouses, professional buildings, or sites with numerous bait points.

Packaging: 3 kg
Presentation: bulk cereals
Formulation: mix of three cereals
Active substance: brodifacoum 25 ppm
Armosa reference: RD-BRD-67002

The Armosa technical sheet confirms the presentation in 25 g sachets or in a 3 kg bulk bucket.

Against Which Rodents to Use Strong 25?

Strong 25 is intended to combat two species:

House Mouse – Mus musculus

The house mouse generally moves in close proximity to its food sources and nesting sites.

Increasing the number of bait stations in areas where activity has been observed allows the treatment to be tailored to its behavior.

Brown Rat – Rattus norvegicus

The brown rat, also known as the Norway rat, can be found around agricultural buildings, livestock, warehouses, outbuildings, and other places providing it with food and shelter.

These two species are the declared targets of Strong 25.

Strong 25 Dosage

The quantities of bait to be placed differ depending on the targeted rodent.

For Mice

For the house mouse (Mus musculus):

25 g of bait per bait station.

With the sachet version, this corresponds to **1 sachet of 25 g per station**. If multiple stations are needed, a minimum distance of **2 meters** must be maintained between two stations. **For brown rats** For the **brown rat (Rattus norvegicus)**: **50 to 100 g of bait per bait station.** When multiple stations are needed, the minimum distance between two stations is **5 meters**. The number of stations should be adapted to the severity and extent of the infestation. ## Where to position bait stations? Before starting the treatment, it is recommended to observe the areas to identify the zones actually frequented by rodents. Stations can be installed: - near nesting sites; - along the paths used by rats or mice; - near usual feeding areas; - close to holes and passages; - in areas where droppings or damage have been noticed; - near hollow structures likely to harbor pests. The stations should be placed **as close as possible to the places where rodent activity has been observed** and, when possible, fixed to the ground or a structure. **Strong 25 must not be placed directly in burrows.** ## Regularly check the stations The setup of baits should be accompanied by regular monitoring. At the beginning of the treatment, Armosa recommends inspecting the stations: **For mice: every 2 to 3 days** **For rats: every 5 to 7 days** Consumed, soiled, or damaged baits must be replaced. Subsequently, a check should be performed **at least once a week** to verify bait consumption, the state of the stations, and the evolution of rodent activity. Rodent carcasses should also be searched for and removed regularly to limit the risk of secondary poisoning of non-target animals. ## Use inside and around buildings Strong 25 can be used **inside as well as outside around buildings**, in accordance with the conditions listed on the label. Outdoors, the baits must be protected from rain, snow, and humidity. Bait points must be covered and installed in locations that are not at risk of flooding. Any bait damaged by water or contaminated by dirt must be replaced. ## The advantages of Strong 25 - Ready-to-use rodenticide bait - Attractive mix of three cereals - Formulation suitable for brown rats and house mice - Brodifacoum dosed at 0.0025%, or 25 ppm - Second-generation anticoagulant - Contains Bitrex, a bittering agent - Two presentations suited to different needs - Pre-dosed 25 g sachets for easy dosing - Economical 3 kg bulk bucket for large needs - Usable inside and around buildings in accordance with the label - Particularly suitable for agricultural environments and livestock buildings - Easy dosage adjustment according to the targeted rodent ## Technical characteristics **Product:** Strong 25 **Brand:** Armosa **Type:** biocide TP14 – rodenticide **Formulation:** ready-to-use multigrain bait **Bait composition:** mix of three cereals **Active substance:** brodifacoum **Concentration:** 0.0025%, or 25 ppm **Family:** second-generation anticoagulant **Mechanism of action:** vitamin K antagonist **Bittering agent:** Bitrex **Targets:** house mouse (Mus musculus) and brown rat (Rattus norvegicus) **Packaging:** 6 x 25 g (150 g) or 3 kg bulk bucket **Belgium authorization number:** BE 2018-0027 **Luxembourg authorization number:** 24/19/L-000 These characteristics are found in the Armosa technical documentation dedicated to Strong 25.  ## Strong 25 and Integrated Pest Management The use of a rodenticide should be accompanied by measures aimed at reducing the causes of infestation. It is particularly recommended to: Remove accessible food for rodents as much as possible; clean up spilled grains and food; store food in suitable containers; identify and block entry points; fill holes and passages whenever possible; eliminate shelters that promote pest establishment; also consider physical control methods, such as traps.

The documentation recommends integrating Strong 25 into a strategy that includes hygiene measures and, where possible, physical control methods.

Strong 25 should not be used as a permanent bait solely to prevent an infestation or monitor rodent activity. If no reduction in activity is observed after the treatment period, the situation should be reassessed.

Precautions for Use

Strong 25 contains brodifacoum, an anticoagulant substance. Therefore, it should be used with caution.

The product and bait stations must remain out of reach of children, birds, pets, livestock, and other non-target animals.

They should also be kept away from food, drink, and animal feed.

The product should be stored in a dry, cool, and well-ventilated place, in a properly closed container and protected from direct sunlight. The safety sheet indicates a maximum storage duration of 2 years under the recommended conditions.

In case of accidental ingestion, do not induce vomiting and immediately consult a doctor, presenting the packaging or label. In case of ingestion by a pet, contact a veterinarian.

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

Strong 25: Two Formats to Adapt the Treatment

With its formulation based on three cereals and a dosage of 25 ppm of brodifacoum, Strong 25 is a ready-to-use solution to combat brown rats and house mice in and around buildings.

The 6 x 25 g packaging offers convenient and directly dosed portions, while the 3 kg bulk bucket better meets the needs of sites requiring numerous bait points or larger quantities.

This dual presentation allows for selecting the packaging best suited to the scale of the treatment while precisely adhering to the manufacturer's dosage recommendations.
