Build an Ant Farm

If you've ever examined an anthill and wondered what's beneath the surface, creating your own ant farm will be a fascinating learning experience. Introducing an ant colony to your own farm will give you a first-rate view of ants building intricate tunnels and paths, then scurrying through like they're on a mission. See Step 1 to learn how to make an ant farm using simple materials you may already have on hand.

Steps

Gathering Supplies and Ants

  1. Get two glass jars with lids. You'll need a large jar and a smaller one that just fits inside. The dirt and ants will be placed in the space between the small jar and the large jar. The small jar functions as a way to take up space in the middle so that the ant colony will build tunnels and lay eggs close to the outer edge, putting these processes in plain view. Skipping this step will allow the ants to burrow deep toward the middle of the jar, which they'll naturally want to do.
    • Different-sized canning jars are perfect for this project. But, if you want your ants to be happy, then buy a larger container.
    • Look for jars without etching, print or raised numbers and letters. Plain, clear glass will give you the best view of the ants.
    • If you'd prefer to have a flat ant farm, check out your local pet store and purchase a skinny aquarium. You can also order an ant farm setup from online retailers.
  2. Prepare a soil and sand mixture. The ants will need a loose substrate that stays moist and allows them to dig and tunnel. If you're planning to source the ants from your yard or a nearby area, your best bet is to use dirt they already naturally live in. Dig up enough dirt to fill up the extra space in your jar. Use a fork or your fingers to loosen the dirt until it's nice and fine. Now mix 2 parts dirt with 1 part sand - less if your dirt is already naturally quite sandy.
    • If you aren't planning on getting your ants from a nearby location, and the dirt you have on hand doesn't seem suitable, you can buy potting soil and sand from a gardening store and mix it up to serve as your substrate.
    • If you order an ant farm kit, it should come with the right mixture for those particular ants.
    • You want the mix to be slightly moist, but not sopping wet. If it's too dry, the ants will dry out; if it's too wet, they'll drown.
  3. Find an anthill. There are many species of ants, but by and large they nest in the ground.[1] Look for anthills in slightly exposed areas in your yard. You'll know it's an anthill by observing the tell-tale volcano-shaped pile of small grains of dirt, with a tiny entrance hole near the top.
    • Tracking ants is another good way to find an anthill. If you see a group of ants walking, follow them back to their nest.
    • Observe the anthill to make sure you aren't dealing with fire ants or another type of ant that bites. Brown field ants are a good bet. If you want to be on the safe side, order your ants online as part of an ant farm kit.
  4. Collect the ants. One you've identified an ant colony, bring a jar with a few holes poked in the top (not one of your ant farm jars) outside, alone with a large spoon, and scoop some ants into the jar. 20 - 25 ants should be a good amount to get your ant farm started. Here are a few things to keep in mind:
    • The ants probably won't reproduce unless you include a queen in your ant farm. An ant colony's queen lays all the eggs, an a group of worker ants - those you're likely to see close to the surface of an anthill - are likely to be sterile. Therefore, if you want to see ants go through the process of laying eggs, you'll need to get a queen - which can be tricky, and would require destroying the natural ant colony.
    • If you're set on seeing the reproductive cycle, a better bet may be to order a kit that comes with a queen ant. That way, you won't have to worry about digging deep into the ant's nest to get what you need.
    • If you create a farm without a queen, the ants will probably die within 3 - 4 weeks, which is their natural lifespan.

Assembling Your Farm

  1. Place a cap on the smaller jar and set it inside the larger one. To keep it centered in the middle of the larger jar, you can put a dab of glue or tape on the bottom before you set it inside. Make sure you put the lid on securely, since you don't want ants accidentally falling in.
  2. Fill the remaining space in the jar with the dirt mixture. Use a funnel to neatly fill the extra space with dirt, or spoon it in. The dirt should not be tightly packed; make sure it's nice and loose, so the ants will be able to move around. Leave about an inch of empty space at the top of the jar.
    • You will now have created a layer of dirt that will serve as the ants' home.
    • The inch of empty space will keep the ants from climbing up the glass and out of the jar when you need to open the lid.
  3. Place the ants in the jar and screw on the top lid. Carefully drop the ants in the jar, making sure they all make it into the fine dirt you provided. Cover the jar and use an awl or a sharp knife to puncture it with tiny holes, to allow oxygen to reach the ants.
    • Make sure not to punch the holes too large, or the ants will escape and build a nest elsewhere.
    • Don't cover the jar with cloth, as ants will be able to chew their way out.

Maintaining Your Farm

  1. Offer them food and moisture. In order to keep your ants happy, you can feed them every few days with a few drops of honey, jam, or pieces of fruit - ants love sugar! Don't overdo it, or you'll have mold in your ant farm. Ants get most of the moisture they need from food, but if it looks like the dirt and sand mixture is getting dry, wet a cotton ball with water and place it at the top of the jar for a few days.[2]
    • Don't give the ants meat or other cooked food. This will attract other types of pests to your ant farm.
    • Don't pour water into the jar. It'll get too wet, and the ants could drown.
  2. Cover the jar when you aren't watching the ants. Ants do their tunneling at night, in the dark. To replicate the environment they're used to, cover the jar with black cloth or construction paper when you're not watching the ants. If you forget to do this, the ants will be stressed out and much less active. They'll also tend to stay away from the glass and spend their time as close as possible to the center of the jar.
  3. Don't shake the jar. Ants are fragile creatures, and shaking the jar or otherwise handling it roughly can cause them to die when their tunnels collapse on them. Handle the ant farm carefully.
  4. Store the farm in a warm room. Place it in a room that tends to stay at a good steady temperature. Don't place it in direct sunlight, or the glass jar might heat up too much and overheat the ants.



Tips

  • When handling with ants make sure they all come from the colony or they will kill each other.
  • If you feed the ants make sure you clean up any leftovers which will prevent building up of mold which will kill the ants.
  • Red ants are usually very aggressive, and black ants are typically more passive
  • When you get your ants, to try to get them to be less aggressive while you get your queen, keep them distracted with sugar and water, just make sure not to use too much!
  • If you go away for a while an ant sitter is a good idea so your ants don't die of dehydration or hunger while you're away.
  • Ants must be cared for like dogs and cats. Pay attention to them!
  • A toilet paper cardboard tube makes a great tube; or you can make some out of recycled cards.
  • If you use the classic round fish bowl, you can use a balloon in place of a cardboard tube. To do this and have a long lasting effect you should fill the balloon with a hardening agent (i.e. plaster, clay, or even cement if you don't mind the weight; really anything that hardens will do). To fill the balloon first set aside a bottle or jug. Then inflate your balloon and (while holding the air inside the balloon) stretch the lip of the balloon over the end of the bottle or jug, this can be tricky and it helps to have a friend assist you. You can then tip the contents (the hardening agent) of the bottle into the balloon leave some air in the balloon, your substance will probably need it to dry. Practice with water before trying your hardening agent.
  • You can also plant grass seeds at the top for added effect. Keep the grass carefully watered, so as not to drown the ants underneath.
  • Don't drop it in the house!

Warnings

  • If you decide to feed your ants dead insects, ensure that they weren't poisoned, as it can hurt, or even kill, your 'colony'.
  • NEVER mix two ant colonies together, they will fight until death and it is cruel to the ants. So if you're catching them not ordering them, make sure you only catch one hill.
  • Be careful of ant bites. If you can use gloves, that's great. To treat ant bites, use calamine lotion or a pharmacy approved itching cream. Ask your pharmacist for assistance.
  • All ants can bite you, but rarely will they, so don't let this put you off, but if you are keeping red ants, they can bite AND have quite a nasty sting, so be very careful. Use gloves.
  • Avoid any ants that are known to be very aggressive towards humans and have painful or dangerous bites.
  • Do not cover the lid of the ant farm - the ants could suffocate. If you must cover it, use a paper towel secured with a rubber band and poke small holes with an earring or pin. Or a fine wire netting.
