What kind of container(s) do I need to raise monarchs?

Plastic or glass containers/cages are preferred because they are easy to disinfect. Wood is difficult to disinfect and should be avoided. Pop-up or net-style tents can also work, but make sure to clean and sanitize them to prevent the spread of diseases. Note that keeping adult butterflies in these types of tents for extended periods of time will damage their wings.

Monarchs should be reared individually in separate containers to prevent disease transmission and for ease in monitoring/reporting to community science programs. Label each container with information about the monarch collected including the date, stage at collection, location in which it was found, and a unique identification number/code.

Here are some suggestions:

• Food storage containers with small holes punched in the lid
• Glass jar with a mesh lid, feel free to put a stick in the container to help them climb
• Mesh pop-up tent
