Our Little Creature Community

This is our worm farm, built up to keep the small ants out (doesn`t), there are two geckos on the farm, various insects growing inside along with shoots of veggies and copious numbers of worms; and now the green ants have invaded as well. I am loathe to kill the green ants but they kill everything else, attacking the worms who are rather defenceless and even the geckos if they can get hold of them! Previously to them invading the community of creatures sort of self regulated with the the sunbirds snatching the odd insect but with all generally thriving.
