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.
