PESTICIDAL MATERIAL FOR HEAT TRANSPIRATION AND METHOD FOR CONTROLLING PESTS BY HEAT TRANSPIRATION The present invention provides a pesticidal material for heat transpiration and a method for controlling pests 5 by heat transpiration that enable to provide a stable transpiration and thus a stable pesticidal effect. A pesticidal material for heat transpiration which has an aqueous pesticidal composition comprising a pesticidal active ingredient, glycol ether and water, and a liquid 10 absorbing wick that is set up so as to be dipped into the composition, the glycol ether content in the composition and the porosity of the wick satisfying the following equation: Equation: 0.17 < a/b < 2.5, wherein the "a" represents the glycol ether content (wt%) in the 15 composition and the "b" represents the porosity (%) of the wick.
