  • the repellent or insecticide is sufficiently volatilized, but the permeable layer 2 prevents the repellent or insecticide impregnated in the chemical retention layer 1 from adhering to the user's fingers when the user touches the chemical volatilization sheet with their fingers, and the permeable layer 2 prevents the repellent or insecticide impregnated in the chemical retention layer 1 from transferring to the tongue when the user licks the chemical volatilization sheet with their tongue.

When the insecticide peak was not detected, it was determined that the insecticide had not migrated to the tongue and was evaluated as ⁇ , and when the insecticide peak was detected, it was determined that the insecticide had migrated to the tongue and was evaluated as ⁇ .
  • Tables 1 and 2 show the results of finger non-adhesive tests and oral non-administrability tests for various mesh sheets that can be used as the permeable layer 2.

Then, multiple hangers holding clothes such as sweatshirts, dress shirts, suits, and coats were hung on the rod-shaped member so that they abutted against each other. At this time, one side of the chemical volatilizing sheet abutted against the front of an adult men's dress shirt (all buttons fastened), and the other side of the chemical volatilizing sheet abutted against the front of an adult men's suit (all buttons fastened). The hangers with the dress shirt and suit were then removed from the rod-shaped member and re-hanged in the same location 50 times each.
  • ⁇ and ⁇ were evaluated as good, as they were not rolled up even when in contact with clothing and were unlikely to reduce the pest control effect of the chemical volatilizing sheet, and ⁇ was evaluated as poor, as they were likely to roll up overall when in contact with clothing and reduce the pest control effect of the chemical volatilizing sheet.
  • Tables 3 to 7 show the chemical volatilization sheets of each example and comparative example, as well as the results of performance evaluations conducted using them.
  • a pesticide volatilization sheet having a pesticide retention layer 1 sandwiched between permeable layers 2 can prevent the user from coming into contact with the pesticide retention layer containing a repellent or insecticide, as long as it has a predetermined bending strength and the ratio of the area of the through holes 21 in the permeable layer 2 to the thickness of the permeable layer 2 is within a predetermined range, and furthermore, while it can deform when it comes into contact with clothing, it is able to maintain a shape that does not fold or roll up.
