So I own a colony of camponotus ligniperda ants with about a hundred workers. But with university coming up i need to find a way to release them back into the wild, preferably while still giving them a chance to survive. The current plan is to keep them in hibernation until the temperature becomes somewhat stable, then drag the terrarium to a nearby forest, wash off the barrier and leave them alone next to a tree trunk or something. Although i don't know if that's the correct way to do it, as i have never released a colony before. At what kind of place should i release them? What is the optimal weather conditions? How do i protect them against predators?
Pretty much any advice on the subject would be appreciated. I really don't want them to die to some bird or ant colony the second i release them.
