Is the mosquito killer useful? How effective is the mosquito killer?
The mosquito killer lamp is one of the commonly used electrical appliances in many households in summer. It uses photocatalyst to kill mosquitoes. Photocatalyst is a kind of catalyst. Under light, the photocatalyst combines water and oxygen in the air to form strong oxidizing hydrogen on the surface. Oxygen free radicals can decompose harmful gases and bacteria in the air, and release CO2 and water. It is a low-carbon and environmentally friendly home appliance. Let's learn about the usefulness of the mosquito killer from the following?
As far as my personal experience is concerned, the effect of the mosquito killer is still okay. Mosquito killers generally use ultraviolet rays to attract mosquitoes to achieve the effect of killing mosquitoes. When we use the mosquito killer, it is best to turn off the light for better results.
When the mosquito is attracted to the mosquito killer, it will automatically fall to the bottom of the mosquito killer and cannot fly out. As time goes by, the mosquito can only die slowly inside. In addition, the editor would like to remind everyone that when we use the mosquito killer, this part of the mosquito killer must be installed more stable. Otherwise the mosquitoes will easily run away.
In addition, the small fan of the mosquito killer can also achieve the purpose of drying the mosquitoes, thereby speeding up the death time of the mosquitoes. If you hear an abnormal sound from the fan, you should turn off the mosquito killer as soon as possible.
The last thing to remind everyone is that it is best not to turn on the mosquito killer that is turned on all night to check the effect of the mosquito, because it is easy to let the mosquitoes go.
