they will indeed try to carry back to the nest saves them time and effort going back and forwards to it
and back on the subject of meal worms from a pet store
1. would it be ok to keep them in a large lunch box?
2. do they need a flooring such as mud of saw dust?
3. do they need some places to hide e.g. cardboard toilet roll?
4.what would i feed them?
thanks Sithmaster676



It won't harm them if you spray some water if they are in there (but don't spray to much) in nature ants do get wet when it rains.
