For many years I have been trying to find a way to control ant populations within huge colonies. I have tried freezing foragers,introducing poisonous bugs and feeding them lower amounts of protein. None of these methods worked well. Then,one day, my brother bought a venus fly trap-insect eating plant. The second I saw it I asked him if I could plant it in one of my outworlds. He agreed and we did it. After few seconds I already saw ants being trapped. I planted few of them in each outworld I had. They are very easy to care for. One plant can catch about 50 smaller ants a day. It works very good and looks great too. I also tried 2 more species of carnivore plants and planted them into outworlds. One of them has pots with slipery walls so ants can't get out if they fall in. Other one has sticky leaves which look like tiny needles. Both species work great,for both big and small ants. They are all cheap-about 5 dollars a piece. I suggest everyone trying one of these!
