Ants are well-represented in most parts of the world except Antarctica. They live in a wide variety of habitats including forests, grasslands, and urban areas. There, they build different types of nests that provide shelter for their colonies.
In this article, we’ll learn more about where ants live as we discuss the following:
- Ant habitats
- Ant nests
- Where do ants live indoors?
We’ll also look into how ants enter houses and how to prevent them.
Ants are incredibly adaptable insects that live in a wide variety of habitats. These habitats range from forests and grasslands to urban areas. 
The specific habitat that ants choose to live in depends on a variety of factors. These factors include the availability of food, water, and shelter. They also consider the climate and topography of the area.
In general, ants prefer habitats that offer food stability and protection from predators. This can include areas with ample vegetation or access to insects and small animals. Some ants also need specific environmental conditions such as high humidity or access to standing water.
Here are some examples of ant habitats:
Forests are a common habitat for ants, as they offer a diverse range of food sources and shelter options. Ants are often found in the leaf litter on the forest floor, where they can scavenge for food and build nests.
Some species of ants also live in trees, either within the branches or in the hollowed-out trunks.
Ants are important decomposers in forest ecosystems. They help break down dead matter and recycle nutrients.
Examples of ants that live in forests include the following:
- Carpenter ants
- Leafcutter ants
- Weaver ants
Ants are also common in grasslands, where they build their nests in the soil or in the thatch of grasses. They play an important role in maintaining the health of grassland ecosystems. They control other insect populations and help aerate the soil.
Here are some ants that live in grasslands:
- Harvester ants
- Yellow meadow ants
Some species of ants have adapted to live in arid desert environments. They are able to conserve water and build their nests in sandy or rocky soil.
Saharan desert ants are one example of ants that live in deserts. These ants have hairs on their bodies that help them survive extreme temperatures.
Certain ants live in wetland environments, such as bogs and marshes. These ants usually nest in the soil.
One example of a wetland ant species is the Crematogaster cerasi. This is a species of acrobat ant native to the Nartctic region
Ants are also common in urban areas, where they can scavenge for food in human settlements. They nest in buildings, gardens, parks, and man-made structures.
There are many ants that live in urban areas. They include the following:
- Odorous house ants
- Pavement ants
- Pharaoh ants
- Argentine ants
Ants build nests to serve as their homes and provide shelter for the colony. They use these nests for food storage and as nurseries for their young.
Ant nests can vary in type, size, and shape depending on the ant species. They can be in the ground, in trees, or inside plants and other structures. 
Here are different types of ant nests:
Soil nests are the most common type of nest that ants build. As the name implies, these are nests that ants build in the soil. These nests consist of interconnected tunnels and chambers. They vary in size and complexity depending on the species of ant and the size of the colony.
Soil nests can be found in a variety of habitats, including forests and grasslands. They may be visible on the surface of the soil in the form of anthills or mounds. In other cases, they’re hidden underground. See this article to learn more about ant mounds.
Some ants like carpenter ants prefer to nest in wood. These ants nest in trees, logs, stumps, and other wooden structures. They dig through wood to create tunnels and galleries that serve as shelter for the colony.
Wood-nesting ants are often considered pests. Their excavations can weaken wood and cause structural damage. See this article to learn more about wood-nesting ants.
Leaf nests are unique to weaver ants. These ants construct their nests by weaving leaves together with larval silk. In doing so, they create a cocoon-like structure that provides shelter and protection. These nests are particularly strong and impermeable to water.
Some ants are opportunistic nesters. Argentine ants, for example, nest almost anywhere. They can nest under rocks, at the base of trees, lawns, and garden beds. They sometimes also nest inside our homes.
As long as they have access to food and water, they will thrive.
Where Do Ants Live Indoors?
Ants can live in various places indoors. They generally prefer to stay near food sources and moisture. They may also prefer to stay hidden in protected areas.
Some common areas where ants may establish nests inside homes or buildings include:
- Kitchens: Ants are attracted to food sources. They may establish nests near kitchens or pantries.
- Bathrooms: Moisture-loving ants may nest in bathrooms. They nest near any water sources like sinks, tubs, and toilets.
- Electrical equipment: Some species of ants are attracted to electrical equipment. These ants nest in computers and appliances.
- Walls, Floors, and Ceilings: Ants also love to nest in dark protected places. They’ll nest in walls and other voids where they feel safe and have close access to food.
How Do Ants Enter Houses?
Ants can enter houses in a variety of ways, including:
- Cracks and Gaps: Ants can squeeze through small cracks and gaps in walls and foundations.
- Windows and doors: Ants can crawl through open windows and doors. They can also slip through gaps in window and door frames.
- Utility lines: Ants can travel along electrical, telephone, and cable lines. They can use any of these as a bridge or a highway straight to your home.
- Ventilation system: Ants can enter through the ventilation system via gaps in the ductwork.
How to Prevent Ants from Entering Your House
To prevent ants from entering your house, here are some steps you can take:
- Keep your house clean: Ants are attracted to food and water sources. Therefore, clean up spills and crumbs promptly. Store food in airtight containers that they can’t access.
- Seal up entry points: Check the exterior of your house for cracks and gaps. Seal them up with caulk or weather stripping. Use door sweeps to seal the gap between the doors and the floor.
- Keep vegetation away from the house: Trim bushes and trees that are touching the house. Ants can use them as a bridge to get inside.
- Fix moisture problems: Ants are attracted to moisture so fix leaky pipes and faucets. Also, make sure that your gutters and downspouts are working properly.
By taking these steps, you can help prevent ants from entering your house. That said, if you already have an infestation you may need to consult a pest control professional. That way, they can identify the species and develop an appropriate treatment plan.
Summary: Where Do Ants Live?
To summarize, ants live pretty much everywhere. Aside from Antarctica, ants are found everywhere in the world. They live in different habitats from forests, deserts, and urban areas. There they build different types of nests that protect their colonies. These nests are built in soil, wood, leaves, or any available cracks.
Some ants even enter and live inside our houses. They can build nests inside our walls, floors, and anywhere else near food and water.
