There's no need to euthanize them if they've already invaded your area.
No need to euthanize an invasive species? haha. Invasive species should always be killed, just because they're there doesn't mean you should let them just stay.
What could also benefit would be people taking queens in and keeping them, but what makes it bad is when they aren't able to control their own colony and end up releasing them. People who release their invasive ants are a part of the problem as well. I don't understand why it's hard for some to just kill them if they're unable to care for them.
