Natural Ways to Get Rid of Ants in House Permanently

What you need
Adult supervision required, breathable mesh or coffee filter, clear glass or clear plastic jar with lid, cotton ball, rubber band, sand or clean soil, shallow dish for food, small pebbles or gravel, small stick or straw for tunnels, spoon or small jar for collecting ants, sugar or honey and water

Step 1

Wash the clear jar and lid so they are clean.

Step 2

Pour a 1-2 cm layer of pebbles into the bottom of the jar for drainage.

Step 3

Pour sand or clean soil into the jar to make a 4-6 cm layer.

Step 4

Gently press the sand down so it is firm and level.

Step 5

Push a few twigs or leaves into the sand for hiding spots.

Step 6

Use a small stick or straw to make tunnels and small chambers in the sand.

Step 7

Lightly moisten a cotton ball and tuck it into one corner for humidity.

Step 8

Place a tiny shallow dish with a few drops of sugar water or a small crumb of fruit on the sand for food.

Step 9

With adult supervision gently collect a small group of worker ants using a spoon or small jar and avoid taking any queen.

Step 10

Carefully tip the ants into the farm opening and let them walk onto the sand.

Step 11

Cover the jar with a breathable mesh or coffee filter.

Step 12

Fasten the mesh or filter with a rubber band so air can get in but ants cannot escape.

Step 13

Observe the ants for 10-15 minutes and watch where they start tunneling.

Step 14

Check the farm every day and give tiny drops of water or a bit of food as needed and release the ants back outside after one to two weeks with adult supervision.

Step 15

Share a photo of your finished ant farm and what you observed on DIY.org.

Help!?

What can we use instead of a clear glass jar if we can't find one?

Use a clear plastic food container or a cleaned clear PET bottle with the lid removed and follow the same steps, covering the opening with breathable mesh or a coffee filter fastened with a rubber band as described.

My sand keeps collapsing when I make tunnels — what should I do differently?

Make sure you pressed the sand firmly and level after pouring the 4–6 cm layer and consider packing it a bit tighter or slightly moistening with the lightly moistened cotton ball before making tunnels with a stick or straw.

How can I adapt this ant farm for younger children or older kids?

For younger kids have an adult pre-wash the jar, pour pebbles and sand, and let them press sand and add twigs while observing briefly, and for older kids let them create tunnels with a straw, measure and record tunnel growth daily, and post observations and photos on DIY.org.

How can we extend or personalize the ant farm once it's set up?

Personalize by layering colored sand before pressing, add a small magnifying lens to the jar, set up a smartphone time-lapse while you observe tunneling, or connect two jars with a sealed tube and compare ant behavior, then share photos and notes on DIY.org.

Facts about entomology for kids

👃 Ants 'smell' with their antennae and leave chemical trails so nestmates can find food.

🐜 Ants can lift about 10–50 times their own body weight — that’s like a kid lifting a car!

🍄 Leafcutter ants are farmers: they cut leaves to grow fungus gardens they eat.

🧪 Myrmecology is the science of studying ants — researchers learn about teamwork, tunnels, and behavior.

🏠 Some ant colonies contain millions of ants working together as one super-organism.

How do I build an ant farm at home to observe tunneling and ant behavior?

To build a simple ant farm, choose a clear jar or shallow plastic container with a ventilated lid. Add a layer of clean sand or loamy soil, tamp lightly, and moisten slightly. Use a stick to start tunnels, then gently introduce worker ants (collect with adult help) into the chamber. Keep the farm in indirect light, maintain slight moisture, feed tiny bits of fruit or sugar water on cotton, and observe tunneling—avoid shaking or opening often to prevent escapes.

What materials do I need to construct an ant farm?

Materials you'll need include a clear jar or plastic container with a secure, breathable lid; clean sand or loamy soil; small pebbles or a layer of gravel for drainage; a spray bottle for misting; cotton balls or a small water reservoir; tweezers or a soft paintbrush to move ants; magnifying glass for observation; shallow dish for food (tiny bits of fruit or honey), gloves for handling, and a tray to place the farm on in case of escapes.

What ages is making an ant farm suitable for?

This activity is best for children aged about 6 and up with close adult supervision. Younger children (3–5) can enjoy watching and learning while adults handle building and ant collection. School-age kids gain responsibility, fine motor practice, and observation skills; teens can manage more complex setups. Always supervise any handling of ants and avoid letting young children handle ants alone to prevent bites or escapes.

What are the safety and ethical tips for keeping an ant farm?

Safety and ethical tips: use local, non-aggressive ant species and never release non-native ants into the environment. Ensure the container has secure ventilation but cannot be escaped through; seal lid mesh. Keep substrate slightly moist and provide small food pieces. Wash hands after handling and avoid pesticides. Limit direct handling—observe more than poke tunnels. When finished, return ants to their original location or contact a local nature center for guidance.
