Abstract
An improved earthworm irritant composition that is highly effective in causing worms to leave their holes during the day time or at night and come to the surface. The composition is mixed with a relatively large amount of water and then poured on the ground, and the effectiveness of the composition is at least in part due to its slow rate of evaporation. The composition of the invention is a liquid and it is essentially comprised of 1,2,4-trimethylbenzene, which is the irritating agent, and a nonionic surfactant which enables the 1,2,4-trimethylbenzene to mix thoroughly with the water that is added.
