PURPOSE:To obtain an insecticidal mat having excellent preservation quality and thermal stability, by including a volatile insecticidal ingredient in cyclodextrin and placing the resultant clathrate material on a mat. CONSTITUTION:An insecticidal mat obtained by including a volatile insecticidal ingredient, particularly preferably pyrethroid based insecticide in cyclodextrin, particularly preferably beta-type and placing the resultant clathrate material on a mat. Oxidation of the volatile insecticidal ingredient can be prevented and stability to light is improved by including the volatile insecticidal ingredient. The volatility thereof by heating is as good as that of the nonclathrate compound. That is, since the volatile insecticidal ingredient is stably present even in preservation of the insecticidal mat as well as in use while heating and moderately volatilized in use while heating, excellent insecticidal effects are sustained for a long period. There is no fear of toxicity without requiring use of noxious oxidizing agents.
