JPS59104303A - Electrothermally fumigating mat of high chemical content - Google Patents

Abstract

PURPOSE:A mat for electrothermally fumigating insecticide that is obtained by impregnating a fibrous flat mat of specific thickness and surface area with high concentrations of pyrethroid insecticide, stabilizer, pigment, perfume and other additives, thus disinfecting effectively not only flies and mosquitoes but also cockroaches, fleas and bedbugs. CONSTITUTION:A fibrous flat mat of 1-1.25mm. thickness and 5-15cm<2> surface area is impregnated with 80-300mg, per mat, of a premix consisting of a pyrethroid insecticide as an active ingredient (e.g. pynamin or pynamin forte), a stabilizer such as phenolic antioxidant and a pigment such as allylaminoanthraquinone, if appropriate, additionally a perfume for mat and/or additives for facilitating viscosity reduction and impregnation such as an organic solvent. The resultant mat is heated with a commercially available electric heater for fumigating a mosquito-killing agent from the mat at 140-180 deg.C to effect sufficient vaporization of the active ingredient and keep the concentration of the ingredient in the air within its effective range for hours.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical connector, and more particularly, to an electrical connector with a thickness of 1
A mat premix consisting of a pyrethroid insecticide as an active ingredient, a stabilizer and a pigment, or a fragrance and/or an additive in combination with a pyrethroid insecticide as an active ingredient, is added to a fiberboard mat having a surface area of 5 to 15 d. 80-8 per mat
00-impregnated high dose electric foot.

So-called electric mats, typified by electric mosquito repellents, are widely used in households, along with mosquito coils, aerosols, etc., but such electric mats are mainly used to exterminate mosquitoes. It's nothing more than that.

BACKGROUND ART In recent years, jori flies have been occurring in storage sheds, poultry houses, garbage disposal sites, etc., and a continuous and effective method for exterminating the flying flies has been particularly desired in surrounding households.

In view of this situation, the present inventors conducted various studies on methods for exterminating flies using electric mats, and as a result, the high-dose electric mat of the present invention as described above was used as a commercially available electric mosquito repellent heater. By heating to 140'C-180'C using a water heater, the active ingredients can be sufficiently volatilized and the concentration in the air can be maintained within an effective range for a long period of time, preventing flying pests such as flies and mosquitoes. In addition, cockroaches, no epsilon, six bedbugs,
The present invention was completed after discovering that it is possible to exterminate mites and the like.
