To raise monarch caterpillars at home, you’ll need a few supplies. There are some great commercial options for rearing monarch larvae. In this guide, you’ll learn the monarch butterfly supplies needed to raise from instar to adult butterfly.
But you don’t have to spend a lot of money to successfully do this. Many of the supplies can be easily made. Or even repurposed using recycled materials. You probably already have many of these supplies in your home.
14 Required Monarch Butterfly Supplies
Here are the tools of the trade – the basic supplies for raising monarch larvae at home.
- Rearing container (plastic food container or cardboard box)
- Clean paintbrush (2) one fine-tipped and wide-tipped brush
- Small bowl
- Plastic measuring cup
- Tissues or paper towels
- Round coffee filters or toilet tissue
- Clorox wipes
- Tweezers (optional)
- Tape (like packaging tape)
- Milkweed Plant
- Foam Pipe Insulation
- Push Pins
- Dental Floss
You can probably find many of these supplies around the home. If not, most are very inexpensive to pick up at the supermarket or department store. You can probably pick up most of these items for $40 or less.
Here’s more on how to use the tools when raising monarch butterflies.
Rearing Container / Monarch Habitat
This is the container where you’ll keep the larvae. There are nice commercial options available.
You can avoid purchasing an expensive habitat by reusing some plastic containers. Many have had success with reusable food containers (like Gladware or Ziploc brands). These will be great for the beginning stages of monarch development.
If you are using a well-sealed food container, create many air holes for circulation. These are required to prevent condensation. Moisture build-up is the enemy of successfully raising monarchs.
Always poke holes from the inside of the container. This keeps the rough edge (burrs) on the outside.
To create holes, use a narrow-diameter tool, like a needle or corkscrew. You can also use a small nail. Be careful not to make too big of a hole or else the newly hatched instars will be able to crawl right out. Remember that 1st instars are the size of small ants.
You can also use a shoe box as a rearing container. The loose-fitting lid is great for air circulation. And they are large enough to hold a large volume of air. You should still poke holes in the cardboard box.
Stage 2: Pupa and Butterfly: Once the pupa has hardened, you’ll need to move them to another area with more space. They will need space to hatch, spread their wings, and fly about.
Some popular options are $40 to $80 (or more). Here is a large (35 x 35 x 59 inches) monarch habitat. You can get a more basic option for under $20.
A small paintbrush is great for handling the newly hatched instars.
Because the caterpillars are so fragile, you need to avoid picking them up with your fingers as much as possible. The paintbrush is great because you can place it in the container and allow the instar to climb on it.
This method will protect it from unnecessary handling and subsequent damage.
Another method for moving the monarch larva is to simply lift the leaf that it is on. Depending on the leaf size and your dexterity, you can also use tweezers.
The larger paintbrush will serve as a small broom for cleaning out the caterpillar poop (frass). You can use the small bowl as a dustpan to put the frass and dry (wilted) leaves in.
Clorox wipes (or a similar antibacterial cleaner) will help prevent unnecessary contamination of bacteria and viruses.
It’s a good idea to wipe all your tools with the Clorox wipe. Then rinse it with water. This disinfects the surface, then removes the chemical, so the monarchs aren’t affected either.
In some areas, you’ll be able to purchase a potted milkweed plant. Some nurseries even grow them pesticide free for raising monarch caterpillars.
For more flexibility, you can order milkweed seeds online and grow the plant as required.
These milkweed seeds include six heirloom varieties and are untreated.
If you’re growing your own milkweed, you’ll want to keep an eye on milkweed bugs. They eat milkweed seeds and sap. They are also known to eat the aphids on the plant.
To limit the mess at the bottom of the container, you can lay a layer or two of paper towels to collect the frass.
Then when you clean it each day, it will be faster and more thorough.

Foam Pipe Insulator and Push Pins
If you need to move the chrysalis, you can use a foam pipe insulator with push pins. This method is pictured above.
