how to kill ants

Although ants are interesting insects and can be fascinating to watch in ant farms, they are pests that do not belong in your house. Since they are small, they can easily get inside a house through cracks in the foundation or under doorways and find their way to your kitchen while exploring for food.

While they don’t carry bacteria harmful to humans, they can be very destructive because they eat wood, which can affect the integrity of a house’s structure. Once they have made their way into your home, ants can be difficult to get rid of, but you can learn how to kill ants with home remedies.

Identifying Ants

To effectively kill ants, it helps to be able to identify them. Ants almost always travel together, so where there is one, there is usually a colony nearby.

Since ants are insects, they will have six legs, a head with compound eyes, and two antennae to feel their way around and smell food and water. They also have three body segments consisting of the head, thorax, and abdomen also called the gaster.

Ants also have one or two segments connecting the thorax and abdomen. These segments, called nodes or pedicels, can help identify what type of ants you have around or in your house. You can also tell ants apart from their size. Tiny ants are about 1/16”, medium ants range from 1/16″ to 3/8″, and large ants are classified as longer than 3/8″.

When Will You Find Ants in Your Home? 

Unfortunately, like many little pesks, ants are one the best types of insects that can surreptitiously find their way into your home. Finding ants in your home depends on a couple of factors.

The type of home you live in, your location, your climate, and the type of year all depend on when you can expect to find ants in your home. Additionally, the type of ant in your home depends on where you live as well. 

For the most part, you can expect to run into ants in your home during the warmer months of the year. When the temperature rises, you can expect to find ants crawling out of their underground homes and thriving in the warm environment under the sun. Because ants are out and about, they will only come into your home if you give them a reason to.

If you constantly leave food lying around your home, then within a matter of hours, a single ant will be able to sniff it out and call on the rest of the colony to come to pick up their share. Because of this, it is imperative that you eat only in designated areas in your home like the kitchen and the dining room.

Additionally, it is super important to always clean up after you have handled food. Leaving food lying around your kitchen is a surefire way to get ants stomping around.

Their head and thorax are dark brown, but their gaster and legs are translucent, which is how they get their name.
