My first check is often the hydration needs, checking that all nests are hydrated, once they are all hydrated, then i move onto the refuse piles within the out worlds, checking for any mites or parasites, I find a great method is to film a short hyperlapse/timelapse of the out world, if you have mites the ground will be covered in small moving dots, its very apparent when you watch the footage back.
Once ive removed all the refuge, using a baby milk scoop the perfect shovel for removing refuge, I then clean the walls, using either cotton bud or a j cloth with some warm water then dry with a j cloth or some kitchen towel, its then time to move onto, feeding & refilling the water feeders.
It takes me a while to get through all the colonies, sometimes I split the larger colonies down over a couple of days.
My test tube colonies are all on 14 day Rotations with exception of the Novomessor Cockerelli and the 2 founding colonies of Rhytidoponera (including competition Queen) which are on 7 day rotations.
