Do not release!
Releasing them will not only jeopardize the local ecosystem, there is a higher chance that they won't be able to survive, and if there is really no other way, they can be frozen humanely.
We provide ants return home service, if you don't want to keep the ants anymore, you can just hand them over to us to take over.
These ants will not be sold twice, but will go to Kaohsiung's primary and secondary schools and other educational institutions as eco-teachers for teachers to use in classes or for students to observe.
