Piss ant wars. I have a decided size advantage, but they have the numbers. My house is under siege. Little armies of piss ants. They have me surrounded and have well established supply lines, garrisons, seemingly inexhaustible resources of troops. I have been using a barrier spray but it has proven almost entirely useless. My latest tactic is these little traps/bate devices. The idea here is that the ants will come in, get the bate and carry it back to the mother ship and (hopefully) to the queen ant herself. The bate is poison. If it works, it's brilliant. The numbers of worker ants, once an advantage, turns to a nightmarish catastrophe with all of them returning with their little poison pills. I have no idea how many colonies there are, One of my trees seems to be housing one. All I know is that there are a lot of ants here. I may be in for a protracted season of war.
