So i have been gradually warming the ants up after their winter rest and am now keeping the night time temps a little warmer. Activity is still very quiet but there is always at least one ant drinking water from the test tube or at the sugar water. The nest chambers are crammed with the bodies of dead flies, roaches and crickets from the previous year, i wonder if they store these incase of shortage, or just to fill the chambers up because they are too wide ??? I would really like to give them something better but i can’t see any mould, i’ll leave it for now i think. I am now using an infra red bulb heating the top of the nest rather than a heat mat. This should give a better gradient of heat in the nest.
