mice control in schools is really important. Rodents are a group of mammals that are distinguished from other groups by the characteristics of their teeth.
In this way, they have pairs of incisors in the lower jaw and one or two pairs of incisors in the upper jaw.
These teeth are large and have no roots and their height is always constant.
There are absolutely no molars in these animals and their place on the jaw is empty and visible.
In most rodents, the cecum is overgrown.
In terms of classification, rodents are divided into two suborders:
A- Suborder Duplicidentata:
which have two pairs of incisor teeth in the upper jaw, the second pair are placed in the form of small columns behind the teeth of the first pair, and rabbits belong to this group.
B- Suborder Sipmlicidentata:
which have only one pair of incisors in the upper jaw.
All types of mice are classified in this group.
Below, we only give a brief description of the species of this suborder that are important in school & agriculture:
First of all, we must specify the type of mouse that we intend to fight to get rid of. Because until the type of mouse is determined, it will be impossible to determine the type of fight and prey and even the type of poison.
For example, we know that phototoxin is used to fight against the klaho mouse and the death rate reaches up to 90%, but if the same poison is used to fight against the varamin mouse or the moghan mouse, the death rate reaches a maximum of 50-60%, or to fight against Barn mice or varamine mice are mixed with 3 to 5% phosphorous.
Therefore, to carry out a fight, you must first of all know the type of rat in the area so that the fight can be done successfully.
The fighting season itself is very important.
For example, in order to fight against mice during autumn and winter, wheat bait with phosphorous causes up to 98% losses, but the same bait causes 35 to 45% losses in spring, because mice do not want to eat high-calorie foods in this season, and in the season In spring and summer, the baits that are prepared based on green grass give better results, or in the varamin mouse, in autumn and winter, the use of bait with walnut kernels gives a good result, but in spring and summer, nest collapse causes losses of about 98 to 99 percent. Gives .
Therefore, one should pay close attention to the fighting season and then choose the fighting method.
They multiply quickly and then spread and spread in the place and make it difficult for the owners of these places to fight against this insect, most of the pest control companies due to lack of expertise and knowledge to fight this insect with incomplete implementation of spraying operations and failure to destroy the eggs. This insect can not only be eradicated.
The choice of poison should be based on where the mice live. If the fight is carried out in the desert and far from the settlement, it is easy to choose the type of poison, but if the same mouse is seen in the places where people live and in cities, then poisons that are safe for humans and livestock must be used.
For example, when a house mouse attacks fields, you can use 3% phosphorous poisons, but if this mouse is seen in homes, you should use safe poisons such as warfarin-coumarin, bromoline, etc.
The instructions that are given to fight mice have been obtained from many studies to be both economical and effective.
Therefore, following the issued orders is mandatory. For example, even though the mouse has a small size, in the fighting instructions, the prey is contaminated with 10% of phosphorus toxin.
Because with the high density of this mouse per hectare, the total live weight of mice per hectare is high and the bait should be consumed with the maximum dose.
In the case of fighting with the varamine mouse, which has a relatively large size, the dose of phosphorus dose will be 50%.
Because according to the density of mice per hectare, the total weight of living organisms per hectare is much less than the first mouse and consuming a lot of poison is not economical.
Before starting the fight, pay full attention to the biology of the target mouse in order to get the maximum use of its weak points to increase the result of the fight.
For example, the chemical fight against the mouse or mouse in the seasons when some or all of the mice have gone into hibernation is ineffective, and mechanical fight should be used.
To prevent the damage of mice, especially in gardens and summer fields, it is very important to clear the fields of weeds or deep plowing in the fall, and it will reduce the density of mice in the spring.

In this regard, general formulas can be recommended in the desert and to fight against rats.
For example, we say that he used wheat as a bait in the winter season and used green bait in the spring.
This is a general command and gives a good result.
But the situation is not like this in the fight against house or warehouse mice and it is not possible to obtain a general formula for choosing the bait, and in any case, the person who oversees the fight must determine the type of bait required for the house or warehouse before baiting.
to find If a mouse is seen in a warehouse, one should previously put some types of non-poisonous substances in the corners of the warehouse and watch for two or three days which bait the mice will pay attention to.
After finding the type of food that mice like in this warehouse or house, they prepare the bait based on that material.
It should be noted here that a house or barn mouse has access to different types of food.
If he feels a shortage, he may get it from nearby houses and warehouses, so choosing bait for such places requires 2 to 3 days of preliminary study.
Formulas to fight rodents and how to prepare them:
1- poisoned wheat bait:
100 kg of wheat, 2 liters of paraffin oil and 10 kg of phosphorous are needed to prepare the bait.
For the first preparation, mix 2 liters of oil with 100 kg of wheat with a good wig and then gradually add Phosphorozang to the wheat and stir with a wig until the poison is evenly mixed with the wheat. 1.5 to 2 kilos of bait per hectare are used sparingly to fight against rats in autumn and winter.
The prepared bait should be consumed on the same day. If they want to use this bait with Meriones mice in autumn and winter, instead of 10% phosphorus, the amount of phosphorus should be reduced to 5%.
2- Bait with walnut kernels:
10 kilos of walnut kernels and 200 grams of paraffin oil, 0.5 kilos of phosphodosing and the preparation method is like wheat bait.
This bait can be used in autumn and winter to fight the varamine mouse in gardens. For this, they place the bait with a spoon inside the active nests.
In this method, all the nests should be knocked down one day before the fight, and the next day baiting should be done only in the holes that have been opened, i.e. active nests.
The amount of bait used in one hectare will be about 0.5 to one kilogram of bait.
3- Green bait:
Green grass (any type of weed or crop plant does not differ) 100 kg, phosphoric acid mixed with ash or talcum powder about 10 kg. The mask and a bucket with a capacity of about one kilogram start the work.
While passing through the field, as soon as he comes across an active nest, the worker picks some grass and shoots it into a bullet the size of the mouse’s exit hole, and one side of the bullet is coated with a mixture of poison and talc, and the side contaminated with poison is inserted into the mouse’s hole and the entrance is He closes the nest and goes to the next hole.
In this method, one day before the fight, all the nests should be kicked and the next day bait should be placed only in the opened holes.
This method of fighting can be used in spring and summer for voles, blue mice and marions. With this amount, you can fight 10 to 12 hectares.
4- Potato or carrot bait:
10 kg of potatoes or carrots and 0.5 kg of phosphodose are needed. First, carrots or potatoes are divided into small pieces the size of a sugar cube.
Then, phosphorous is gradually sprinkled on these parts and mixed with a wig so that the poison is evenly mixed with the bait and baiting should be started immediately.
This method can be used for water mice or domestic mice in fields in summer and autumn, and baiting should be done in the evening.
5- Bait with dry hay:
10 kg of dry alfalfa, 1 liter of sugar beet molasses, and 1 kg of phosphodosage will be needed. This method can be used on snowy days to fight rabbits.
To prepare the morning side, sugar beet molasses or 10% juice solution is gradually sprinkled on the dry hay and the hay is turned upside down until the solution soaks the hay evenly.
Then they cover it with a sack or nylon and leave it like that until the evening so that the hay absorbs moisture.
In the evening, hay is divided into small bunches (8 to 10 hay stalks in each bunch). Then they sprinkle phosphoric acid on it and stir it slowly.
They spread this bait in the evening on the surface of the garden which is covered by snow and is attacked by rabbits.
A small bunch of hay is enough for every 10 square meters. The next morning, the bait that was not used by the rabbit should be collected from the garden and destroyed.
6- Bait with bread and jam:
This method is specific for mice. The required ingredients are 10 kilos of white bread, 200 grams of jam, preferably apricot jam, and 0.5 kilos of phosphoric acid.
On the evening side, they cut the bread in half and spread jam on it, try to have apricot pieces on the bread, then they sprinkle Phosphorozang on the jam and put the two sides of the bread on top of each other, and then divide it into small pieces. and they place shakul in the place of transportation and the next morning they collect and destroy the baits.
7- Collapse of nests:
Required materials: 20 kg of talc and 10 kg of phosphorous.
Talc and phosphorous are mixed well in a closed container by turning the container. Then they sprinkle this dust into the nest with small hand dusters.
In this way, one day before the fight, all the nests should be knocked down, and the next day, they should do the dusting only in the opened nests.
This method is mostly used when rats such as the Maghan mouse (when the desert grass is dry and the weather is hot) or the Varamin mouse (in the spring) refuse to take the prey.
