Are mothballs useful for cockroaches?
It has a certain expulsive effect.
Mothballs emit a pungent odor, and cockroaches are more sensitive to this odor and usually avoid the place where mothballs are placed, so mothballs have a certain expulsion effect on cockroaches.
But mothballs can not kill cockroaches, so the cockroaches can not be eradicated, to kill cockroaches is best to use pesticides directly or spray some soapy water in the cockroach-infested places, soapy water can block the cockroach's breathing holes, so that it can be killed.
Is the smell of mothballs harmful to people?
There is a certain harm.
Mothballs on the market are generally synthetic mothballs or naphthalene pills made of dichlorobenzene as raw materials, this white crystal ball will emit a pungent odor containing dichlorobenzene, and dichlorobenzene is easily damaged to people's nerves and blood systems after being ingested by the respiratory system.
Naphthalene, another substance in the mothball gas, is also harmful to the human body, and ingestion into the body will interfere with the production of some important substances, so it is recommended to inhale as little as possible the gas emitted by mothballs.
The correct way to use mothballs
Wrap it up and put it in the corner.
Mothball is a colorless transparent, flammable, hydrocarbon with a special aromatic odor, which is an industrially processed anti-moth product, the main ingredients of which are: p-dichlorobenzene, naphthalene, synthetic camphor.
They are both highly volatile and toxic. When using mothballs, it is recommended to wrap the mothballs with white paper or white cloth to avoid direct contact with clothing, and then place them in the corner of the wardrobe or box, which can play a better insecticidal effect.
Why do mothballs get smaller and smaller
Sublimation becomes smaller.
Because mothballs are an organic compound that easily sublimate into a gaseous state and become smaller, and this is also the process by which mothballs play a role, we will smell mothballs and see their insect repellent effects.
Mothballs are sublimated all the time, generally a mothball volatilized at room temperature for about half a year will disappear, so in order to maintain the effect of deworming, remember to supplement mothballs in time.
