Rats can transmit food poisoning bacteria such as Salmonella and infectious diseases such as leptspirasis, and can cause fires by biting pipes and wires in homes, so it is important not to invade homes.

Intrusion prevention (40 seconds video)

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

  1. Be sure to put food in containers and cupboards, put garbage in containers with lids, and clean up those that are likely to feed on rats.
  2. Let's clean up what is likely to be the material of the nest.
  3. If there is a hole of 2 to 3 cm, such as a ventilation opening under the floor, a gap in the door pocket, or a gap in the eaves behind the roof, you can enter. Use wire mesh, board, putty, etc. to block the entrance to the building.

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

  1. Rats have the habit of walking along the corner, so install the adhesive sheet near the wall. Also, install it around the nest or near the entrance. If there is no effect, let's change the placement method.
  2. When capturing using a basket, keep it on a shaft near a rat's path for at least 3 days. We rent rat traps (capture baskets) in Health Sanitation Division.

What is a rat sign?

The evidence that there is a mouse is called a rat sign. The passage of the rat is often constant, and the rat shines black due to body fat and dirt attached to the body that prefers beams and columns.
In the passage of the rat, the ground is compacted and glossy. In addition, feces and footprints are also rat signs. With a rat sign, guess the entrance or consider where to place the adhesive sheet or basket.
