Autumn has always been the typical season of the invasion of rats and mice in the city.
During the summer season, these rodents enjoyed the richness of the countryside, where they could find cereals and water in large quantities, an ideal condition to live and reproduce. In autumn, on the other hand, due to the cutting of forage in the fields, there is a real migration of the murini from the countryside to the city and industrial areas.
The three most common and dangerous species are the Rattus Rattus (black rat), the Rattus Norvegicus (sewer rat) and the Mus Musculus (pet mouse), carriers of microorganisms dangerous to humans and domestic animals.
How to Intervene
In order to eliminate the presence of rats and mice, it is advisable to plan a series of deratization interventions, which are carried out mainly through the use of ratticide baits. The latter are protected in special containers (bait dispensers or dispensers) to prevent them from coming into contact with, and possibly being ingested by children or animals not subject to deratization (dogs, cats, etc. …).
These baits will be periodically modified in order to vary: the active ingredient, the physical form and taste. The final objective is to avoid phenomena of addiction to poisons, overcome the natural distrust of rodents, and meet their “tastes”.
The prolonged use of the same poisonous substances, in fact, causes a sensitivity to the products, with the effect that rodents eat without any consequences for their safety.
In the same way, changing the physical shape of the baits neutralizes their distrust, avoiding that they can associate the death of a similar one with the ingestion of a bait. If this were to happen, they would signal the latter with precise conventional signs, such as the deposit of excrement or urine; from then on, no mouse would ever touch a similar bait again.
Finally, changing the attractive part of the bait, varying its taste, meets the need to propose, together with the poisons, foods particularly appreciated by the rodents.
To prevent infestation of rats and mice, the following precautions should be observed:
- Ensure that there is no opening to the outside space. Seal all potential entrances larger than 1.3 cm in diameter with concrete, steel wool or polyurethane foam.
- Extirpation of vegetation on buildings (ivy and other climbing plants).
- Prevent tree branches from coming into contact with the building.
- Do not leave food and water unattended, cleaning the rooms thoroughly.
- Store pet food in sealed containers.
