As summer's heat arrives, pests like cockroaches, mosquitoes, flies, and rats make their appearance, collectively known as the "four plagues of the home." Especially problematic are flies and mosquitoes, which not only buzz but also bite people's skin and can even transmit various bacteria. In daily life, it's crucial to carry out pest control to ensure there are no mosquitoes or cockroaches in the home.

What are the "Four Pests"?

Mosquito

Hot summer nights bring an increase in mosquitoes, especially those buzzing loudly and biting the skin, leaving itchy, bumpy red welts. Female mosquitoes feed on human blood to develop their eggs, ensuring the next generation of mosquitoes is born. Male mosquitoes are harmless, do not feed on blood, and are smaller in size. They prefer to bite individuals with fast metabolism, rapid blood circulation, and higher base body temperature. Some people are allergic to mosquito bites and may even contract diseases like dengue fever.

2. Fly

Flies come out in hot weather, though they don't bite, they do bite into food, posing a higher risk. Flies rub their feet on food because their feet are equipped with sensitive taste organs, and they must clean off any food particles before continuing to enjoy their meal. Flies may also excrete and vomit into the food simultaneously, so any food touched by flies is not safe to eat. Neglecting this can lead to the spread of typhoid and tuberculosis.

3. Rats

Rats are absolutely讨厌 pests, ruining everything from food and drinks to toys. They are a major headache for many. These creatures severely damage household环境卫生 and can even spread diseases. A portion of the hemorrhagic fevers are caused by rats.
