Currently out of my house living in dorm of my school. And happen to get call from friend about a queen ant, I been wanting to start a ant colony for quite a while now so I go to check it out and happen to find a carpenter ant queen. How do I keep it alive for like a day and a half until I can go back home where I have an ant farm? Currently had no real container to hold it so had to improvise any advice would be really appreciated.
