Late at night on December 10, a four-story apartment in Chuo-ku, Kumamoto City, Japan, suddenly exploded.
Police and firefighters rushed to the scene of the incident after receiving the alarm and found that the explosion site was located on the second floor of the apartment.
After an explosion occurred in the house where a 54-year-old uncle lived, the scene was in shambles:
The windows of the balcony were shattered by the violent explosion, and the quilt on the hearth in the house also showed fire marks.
The uncle had some of his hair burned, and he had minor burns on his face and neck, and was later taken to the hospital for treatment.
After two days of hospitalization, the uncle was able to be discharged from the hospital.

Why did a sudden explosion occur in a quiet residential building in the middle of the night?
The uncle recalled that he was cleaning up his room when he saw cockroaches appear.
So he took out the insecticide and sprayed it at the cockroaches.
Uncle really hated cockroaches, so he sprayed insecticide continuously for about a minute.
I guess I didn't stop until I ran out of pesticides, otherwise I would have to continue spraying.

We don't know if he eliminated the cockroaches, but just a minute later, tragedy struck.
There was an explosion in the house, which directly blew the uncle away.
The police preliminarily judged that it should be because the man sprayed a lot of pesticides in the house.
The flammable gases in it are ignited by the high-temperature furnace being used, which can cause an explosion and fire.

Pesticides generally contain highly volatile and flammable solvents.
The "spraying" of insecticides is done by means of propellants in liquid tanks, and the main components of these promoters are hydrocarbons propane and butane.
The above-mentioned substances have a low ignition point and are highly flammable and explosive.
If the concentration of pesticides in a confined space is too high, it may cause an explosion when it encounters an open flame or electric spark.
Therefore, on the bottle of insecticide spray, there are remarks such as "stay away from open flames", "do not use near flames and fireworks", "strictly prohibit violent collisions" and other signs.

Japan Kumamoto City Fire Department,
In the past 10 years alone, there have been 22 sprayer-related fires in the area.
In four of these cases, after using pesticides and other supplies, they lit fires and smoked cigarettes, which led to explosions.
The Kumamoto City Fire Department reminds you to pay attention when using sprayers such as pesticides and deodorants:
(1) Keep away from open flames when using;
(2) It is best not to use it continuously for more than 40 seconds;
(3) After using in confined spaces such as indoors and cars, pay attention to opening windows for ventilation;
(4) Avoid high temperature when storing;
(5) Spray all before discarding.

The use of pesticides led to explosions, causing property damage and injuries, and similar incidents have occurred many times before.
At around 10 p.m. on April 13, 2016, an explosion occurred in an apartment in New Jersey, USA.
There were two adults and one child in the house at the time, and they were taken to the hospital after the incident.
Local fire spokesman Garrett M. Giberson revealed,
There are indeed a lot of cockroaches in the building. A man inside the house sprayed insecticide to get rid of cockroaches and did not open the window until he felt headache and dizziness.
Unexpectedly, the cockroaches could not be eliminated, but caused a violent explosion.
As a result, windows flew out, doorways were bent and deformed, and the kitchen area was badly damaged.
When rescuers arrived at the scene, many cockroaches were still seen crawling in the apartment.

One morning in April 2020, an explosion occurred and collapsed in a house in Sydney, Australia.
Neighbors were woken up by the sound of explosions and rushed to the scene to rescue them.
The house is up to 90% damaged and has been "completely scrapped".
Fortunately, the seven members of the family were not in danger of life, and several of the injured were taken to the hospital for treatment.
The local fire and rescue department said the explosion was caused by an overdose of pesticides, and they determined that the homeowners used far more pesticides than the merchants had suggested.
Firefighters said the explosion was caused by "10 bottles of insecticide and a gas stove."

It is indeed annoying to watch cockroaches and other insects crawl around the house.
However, it is still necessary to pay attention to the ways and means of insect control to avoid causing more serious damage to yourself......
