Abstract

The invention discloses a domestic controlled-release insecticidal composition, which is applicable to being sprayed indoor or into a closed environment for controlling insects, capable of slowly releasing effective insecticidal constituents, and persistently effective on killing domestic common pathogenic insects such as mosquitoes, flies, dust mites and the like. The invention further provides a disposable aerosol sprayer which releases the composition in a spray form and is convenient in use. The domestic controlled-release insecticidal composition comprises cellulose, palygorskite, essence, betaine type amphoteric surfactant and the like, which are well compounded, particles are further evenly coated by a novel supercritical impact particle coating method so that reunion tendency easily occurring in the conventional means is relieved, uniformity of microcapsules is improved, and common advantages of the existing supercritical coating methods are retained. The domestic controlled-release insecticidal composition is effective in insect killing, and evident in slow release.

Description

technical field

[0001] The invention relates to a household slow-release insecticidal composition, in particular to a household slow-release insecticidal composition comprising insecticide slow-release microcapsules. The composition is suitable for killing insects indoors and in closed environments by spraying, can slowly release insecticidal active ingredients, and maintains long-term killing effects on mosquitoes, flies, dust mites and other common household pathogenic insects. Background technique

[0002] Pyrethroid compounds are useful in controlling mosquitoes and are well known for their high insecticidal activity. However, the existing various mosquito and fly killing liquids on the market are sprayed indoors during use. The medicine volatilizes quickly and can effectively kill the pests. However, due to the rapid release of the medicine, the maintenance time of the medicine effect is very short, and it needs to be sprayed from time to time. Inconvenience to users. ...
