Dougal nods,"That sounds like a good idea, Tet. Might prevent it from bringing more of his friends... if giant ants even think that way."
Dougal retrieves a vial of oil from his pack. "I have oil, but do not have a lantern for burning it. I guess I sort of figured we wouldn't roll our one lamp down a ravine... Let's use the light of the burning oil to figure out where we are, as well."
Dougal pours a trail of oil over the ant tracks for as long as he can until the oil runs out. Then, when everyone is ready, he borrows one of the burning torches to light the trail of oil.
