CURIOSITIES ABOUT RATS AND MICE

People always asked themselves why the ultrasonic systems do not have the
best results as to fighting rats plagues. It is very important the location of these
devices, as any piece of furmiture, building materials and
including the electrical appliances may affect the output of the
ultrasonic repellents device. It should also be mentioned that people use
to think that using a huge repellent device is the right choice to protect
the entire house. Yet it is preferable to put a small device insede each
room because in this way the repellent device system workd at its best.
When choosing a rat repellent device is very important to make the
difference between the sounds tha can be detected by the human hearing and
the ultrasounds, which humans cannot detect.

The ultrasonic repellent devices should
not be mixed with othes elimination methods, such as bait trap and poison,
because they do not work as expected, but on the contrary.

detecting the poison, the Norwegian rat is the best, being able to
detect the chemical substances in very small concentrations within any food.

Judging animals was
quite a common thing until the beginning of the twentieth century; it is not surprising because the animals were
considered a member of the family by necessity and not so much by affection. It was not unusual to
sentence pigs to death for having eaten children or sentence rats for
having devoured some crops. This
led to establish a sort of a compensation for the death of an animal. An example
was the diocese of Autun which judged the rats that had eaten
great part of the harvest in Burgundy. The lawyer was a certain Chasseneux,
who managed several postponements by different causes
because he did not have
enough time to join together all the rats, or because the rats did not
have protection on the way to the court, or because of possible damage to the cats, etc.
until the people got
tired of a so expensive and long trial, postponing it for ever
and admitted that Chasseneux and the rats were right.

When we
first see a rat inside the house we do not worry about it, but we should
know that rodents are social animals that live in colonies and if we see
one rat is because behind it there is a group of rats. Moreover, rats are night animals;
if during daytime we notice a lonely rat this means that it is a submissed
rat in the colony, so that it had to change its feeeding schedule. Seeing
this we should think that the previous night would have been much more
rats.

Sometimes
we can feed the mouse for a few days and then place the trap.
