Document Type and Number:
Japanese Patent JPS62502693
Kind Code:
A
Abstract:
An article for the sustained release of an insecticide into the ambient air comprises an elastomeric matrix, with the insecticide dissolved in the matrix. The matrix material has a modulus between about 104 Pa and about 108 Pa at 23 DEG C., and a glass transition temperature less than 0 DEG C. The matrix comprises polyurethane formed by reacting hydroxyl-terminated polybutadiene or polyisoprene and 4,4' diphenylmethane diisocyanate, and the insecticide is 2,2' dichlorovinyl dimethyl phosphate. The insecticide-containing matrix is contained in a plastic bottle, and typically protected against inadvertent skin contact by means of a dermal barrier. The article also comprises means for activating the article such that, prior to activation, release of insecticide into the ambient air is prevented, whereas such release can take place after activation. Exemplary activation means comprise a metal foil seal of the plastic bottle. The article is effective in controlling insect infestation (e.g., ants, fire ants, bees, wasps, cockroaches) in enclosures, e.g., enclosures of the type used to protect outdoor utility equipment.
