Scientists have identified thousands of known ants species around the world. And only a few of them bug humans. Most ants live in the woods, or out in nature. There, they keep other creatures in check, distribute seeds, and clean dead and decaying materials from the ground. A very small percentage of ants do harm to humans. But those are incredibly challenging to control. They are small enough to easily slip inside your house. Live in colonies that number in the tens of thousands to the hundreds of thousands, and reproduce quickly. That makes them good at getting in, and hard to kick out. Once they settle in, these insects start affecting your home. In addition to barging ants, other species can cause different kinds of damage. Some, like carpenter ants, can undermine a home structure, while others interfere with the electrical units. Unfortunately, our homes are very attractive to ants, because it provides everything the colony needs to survive, such as food, water, and shelter.So, how can we prevent ants from getting into our homes? Most important of all, avoid giving ants any access to food, particularly sugary food because ants have a sweet tooth. We also need to clean up spills as soon as they occur and store food in air-tight containers. Even garbage attracts ants, so empty your trash as often as possible. And store your outside garbage in a lidded can, while away from doors and windows.

科學(xué)家們已經(jīng)在世界各地發(fā)現(xiàn)了成千上萬(wàn)的目前已知的螞蟻種類。其中只有少數(shù)是在人類社會(huì)里生活的蟲子。大多數(shù)螞蟻生活在森林里或大自然里。在那里，他們與其他生物共存，保持生態(tài)平衡，將植物種子帶往各地，清除地面上衰敗和腐爛的物質(zhì)。極少數(shù)的螞蟻種類對(duì)人類有害。但這些都是很難控制的。它們小到可以很容易地溜進(jìn)你的房子。生活在幾萬(wàn)人到幾十萬(wàn)的群體中，并迅速繁殖。這使他們很好地進(jìn)入，并難以趕走。一旦他們定居下來(lái)，這些昆蟲開(kāi)始影響你的家。除了工蟻，其他物種可以造成不同類型的損害。有些螞蟻，比如木匠蟻，會(huì)破壞房屋結(jié)構(gòu)，而其他螞蟻則會(huì)干擾電氣裝置。不幸的是，我們的家園對(duì)螞蟻非常有吸引力，因?yàn)樗峁┝讼伻荷嫠璧囊磺校热缡澄铩⑺妥∷Ｄ敲矗覀冊(cè)鯓硬拍芊乐刮浵佭M(jìn)入我們的家園呢？最重要的是，避免讓螞蟻吃任何食物，尤其是含糖的食物，因?yàn)槲浵佅矚g吃甜食。我們還需要在食物袋子出現(xiàn)空洞時(shí)立即進(jìn)行清理，并將食物儲(chǔ)存在氣密容器中。即使垃圾也會(huì)吸引螞蟻，所以要盡可能多地清空垃圾桶。把外面的垃圾放在有蓋子的罐子里，遠(yuǎn)離門窗。
