Rats not only threaten human health, but also cause great damage to our lives.
Let's get rid of it after fully understanding the habits of rats.

Damage to mouse
Hygiene damage
- Salmonella bacteria in mice excrement can cause food poisoning.
- It is bitten by a house mites that parasitizes rats and causes itching.
Physical and economic damage
- It bites furniture and food to cause damage.
- It bites electric wires and gas pipes to create a cause of power outages and fires, and bind computer cables to paralyze their functions.
In this way, you can get rid of it!
The basis of rat control is "environmental improvement", which is to create an environment where rats are difficult to live.
Extermination using equipment and chemicals is effective only after taking environmental measures.
Creating an environment where rats are difficult to live (environmental control)
Eliminate food to feed
- Put the food in a container with a lid.
- Let's keep the kitchen tidy.
- Don't leave kitchen garbage or water.
Blocking the entrance
- Attach wire mesh to drains, vents, etc., so that rats do not enter.
- Block holes in piping gaps in pipes and around the introduction of air conditioners.
- It may pass through even a hole of about 1 cm.
Not let them build nests
- Create nests under the floor, behind the ceiling, closet, drawer, etc.
Let's try to keep it organized and clean. - Paper, cloth, birches, etc. will be used as nest materials, so do not leave them alone.
Capture of rats (physical extermination)
Although it is generally considered inefficient, it can be useful in places where pesticides cannot be used.
When using equipment, be careful not to get injured.
How to use basket
- Continue to set it up for more than 3 days after rats appear.
- Fresh ingredients such as Satsuma fried chicken and sweet potatoes are used for food.
Method of using adhesive sheet
Set up in the aisle for more than 3 consecutive days.
Exterminating with poisonous feeds (chemical extermination)
It is a method of mixing the rat's favorite food and feeds it to cause poisoning.
There are two types of insecticides: acute poison and cumulative poison.
Choose the right one according to the type of mouse.
Coumarin-based insecticide
It is a drug that has a blood coagulation blocking effect, and has a fatal effect when eaten continuously for 4 to 8 consecutive days.
Acute killer (novolmide)
It is effective to feed the lethal dose at once.
Precautions when using drugs
- During the hot season, rats that have died in hidden places will rot and cause odors, so it is better to avoid using them outside of winter.
- Clean up the food that becomes food and drives it into hunger.
- It is set up in places where you are active or near the street.
- If you don't eat it as a pesticide, mix it with the rat's favorite food and make it a dumpling or sprinkle it.
In that case, be careful not to eat people or pets accidentally.
Confirmation of effect
After extermination, be sure to check if the effect has been obtained.
Post-processing is also important.
Spray insecticide on the place where the mouse was or dead.
