For the past couple of days, I've been fighting a painful battle with a red ant colony which has invaded my hostel room. They look like fire ants and are very aggressive. The ants seem to prefer my wardrobe and unused clothes for some reason. I've cleaned the room twice and tried to wash away the pheromone trail, but that didn't work and the ants were back in a couple of hours. So, I conceded defeat for the day, left the hostel and went home. Tomorrow I'm going to bring the heavy artillery.
