Rats can transmit food poisoning bacteria such as salmonella and infectious diseases such as leptospirosis, and can cause fires by biting house pipes and wires, so it is important not to invade the house.

In order to reduce the number of rats, it is important to first create an environment where rats are difficult to live.

  1. Be sure to put food in a container or cupboard, put garbage in a container with a lid, and clear up what is likely to feed the rat.
  2. Let's clean up what might be the material of the nest.
  3. If there are holes of 2-3 cm, such as underfloor ventilation openings, gaps between door pockets, and gaps in eaves behind the roof, you can enter. Use wire mesh, boards, putty, etc. to block the entrance to the building.

There are two ways to control rats: capturing with an adhesive sheet or catching with a basket.

  1. Mouses have the habit of walking along the corner, so place the adhesive sheet near the wall. Also, install it around the nest or near the entrance. If there is no effect, try to change the placement method.
  2. When capturing using a basket, keep it for at least three days on a nearby shadow such as a mouse path. We rent rat catchers (capture baskets) in Health Sanitation Division.

What is a rat sign?

The evidence of a mouse is called a rat sign. Rats' passages are often constant, and bear rats glows black due to body fat that walks along beams and pillars and dirt on the body.
The aisle of the rats is lustered by the ground. In addition, feces and footprints are also rat signs. Using the rat sign, you can guess the entrance or consider where to place the adhesive sheet or basket.
