This is my ant trap, which as no poison.
It's basicly a glass jar with water and dish detergent in the bottom and a pipe with sugar in the tip.
To do it start by the bait. Get a plastic lid and make a hole on it, secure the other lid in the pipe's tip with electrical tape, line the pipe with the world's slippest material, Teflon, an pass the pipe throw the hole. Then mixture water and dish detergent and put it in the bottom of the bottle. It has to be enough to cover the down lid, but as less possible, about 1 cm above the lid, put the bait on it without sugar and burial the bottle near the anthill and finally put the sugar on the lid.
