Stelliox 25: A Water-Repellent Block Against Rats and Mice

The presence of rats or mice around a chicken coop, a farm, an agricultural operation, a warehouse, or an outbuilding can quickly become problematic.

Stelliox 25 is a rodenticide bait in the form of a ready-to-use paraffin block.

Its formulation has been developed to combine two important qualities: the food attractiveness of the bait and its resistance to moisture.

The incorporation of paraffin helps maintain the cohesion of the block when placed in a damp environment, while the grains and flour enhance its attractiveness to rodents.

This formulation makes Stelliox 25 particularly interesting when the conditions encountered are less favorable for using a loose grain-based bait.

Water-Repellent 25 g Blocks

Stelliox 25 is available exclusively in 12 blocks of 25 g, for a total weight of 300 g.

The blocks allow for easy handling and distribution of the bait among different stations.

The solid paraffin-based formulation also has the advantage of better resisting moisture than a bait made solely of grains. However, Armosa documentation specifies that the baits must remain protected from weather and that any bait altered by water or contaminated must be replaced.

Difénacoum 25 ppm: Second-Generation Anticoagulant

Stelliox 25 contains 0.0025% difénacoum, which corresponds to a concentration of 25 ppm.

Difénacoum belongs to the chemical family of 4-hydroxycoumarins and is part of the second-generation anticoagulants.

Its mechanism of action is based on its role as a vitamin K antagonist, a vitamin essential for the normal blood coagulation process.

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

Stelliox 25 also contains Bitrex, a bittering agent included in the formulation.

Against Which Rodents to Use Stelliox 25?

Stelliox 25 is specifically intended to combat:

House Mouse – Mus musculus

Small and discreet, the house mouse can settle in buildings, outbuildings, and storage areas where it easily finds food and shelter.

Its limited range of movement generally implies placing bait stations relatively close to the areas where its activity has been observed.

Brown Rat – Rattus norvegicus

The brown rat, also known as the Norway rat, is frequently encountered around buildings, farms, breeding sites, and areas where food is available.

The Stelliox 25 technical documentation specifically identifies the house mouse and brown rat as target species.

Dosage of Stelliox 25

The dosage must be adapted to the targeted rodent species.

For Mice

For the house mouse (Mus musculus):

25 g of bait per bait station, or 1 block of 25 g.

When multiple stations are necessary, 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.

This represents the equivalent of 2 to 4 blocks of 25 g per station, depending on the required quantity.

When multiple stations are used, a minimum distance of 5 meters must be maintained between two stations.

The number of stations should be adapted to the severity of the infestation and the areas actually frequented by the rodents.

Where to Place the Bait Stations?

Before starting the treatment, it is recommended to carefully observe the premises to identify signs of rat or mouse activity.

The stations can be positioned:

• near nesting sites;
• along paths taken by rodents;
• close to their usual feeding areas;
• near holes and passage points;
• in or near hollow structures;
• in areas showing signs, droppings, or other signs of activity.

It is also recommended to remove as much as possible other food sources that could compete with the bait.

Stelliox 25 must not be placed directly in burrows. Use Stelliox 25 in a Secure Bait Station Stelliox 25 blocks must be placed in secure bait stations. This precaution helps limit access to the product by children and non-target animals. The stations should be installed as close as possible to areas where rodent activity has been observed and, where possible, be fixed to the ground or another structure. In environments with chickens, ducks, or other livestock, it is particularly important to make baits completely inaccessible to animals. A Formula Suited to Humid Environments One of the main benefits of Stelliox 25 is its paraffin-based formulation. The composition, combining paraffin, grains, and flour, results in a bait that maintains good resistance to moisture without sacrificing its attractiveness. This feature can be especially useful in agricultural buildings, outbuildings, basements, garages, livestock areas, or other places that may be significantly humid. However, waterproof does not mean the bait should be left directly in the rain or water. For outdoor use, bait points should be covered and installed in locations that are not at risk of flooding. Any block damaged by water or contaminated should be replaced. Regularly Monitor the Stations Once the blocks are installed, the bait stations should be regularly monitored. At the start of treatment, Armosa recommends an inspection: For mice: every 2 to 3 days For rats: every 5 to 7 days Consumed or damaged baits should be replaced. Subsequently, the stations should be inspected at least once a week to monitor consumption, the condition of the bait, and the evolution of rodent activity. Rodent carcasses should also be searched for and removed regularly to reduce the risk of secondary poisoning.

Stelliox 25 and Integrated Rodent Management For best results, the use of a rodenticide should be accompanied by measures aimed at eliminating conditions favorable to the establishment of rats and mice. It is particularly advisable to: collect spilled grains and food; limit access to food for chickens and other animals; store food in suitable containers; remove accessible food waste; identify and seal entry points; fill holes whenever possible; reduce areas that could serve as shelter for rodents; also consider physical methods such as traps.

The Armosa documentation recommends integrating the product into a strategy that includes hygiene measures and, whenever possible, physical control methods.

Stelliox 25 should not be used as a permanent bait simply to prevent potential infestation or monitor rodent activity.

Precautions for use

Stelliox 25 contains an anticoagulant substance. The product should be used with caution and according to the instructions on its label.

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

They must also be placed away from food, drinks, and feed intended for animals.

The product must be stored in a dry, cool, and well-ventilated place, away from sunlight and out of reach of children and animals. The safety data sheet indicates a maximum storage duration of 2 years under recommended conditions.

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

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

Stelliox 25: a practical water-repellent block for controlling rats and mice

Thanks to its formulation combining paraffin, grains, and flour, Stelliox 25 combines attractiveness and moisture resistance.

Its format of 12 blocks of 25 g allows easy distribution of the 300 g of bait among the different stations and simply complies with the recommended quantities: one block for a mouse and two to four blocks per station for the brown rat.

This presentation thus offers a particularly practical solution for controlling rodents in buildings, outbuildings, farms, and other areas where moisture may make the use of a classic bait less suitable.
