Embodiment 1
[0039] Embodiment one: the test of indicator volatilization period
[0040] In an indoor environment with no direct sunlight, air circulation (that is, not closed), and a wind force of level 0, under the conditions of a temperature of 25±2°C and a humidity of 70±5%, the volatilization cycle of the odor indicator is tested. The test results are shown in Table 1.

Abstract
The invention discloses a spray for controlling sanitary insect pests. The spray comprises an active ingredient and a dispensing medium, wherein the active ingredient is one or a combination of both of 2,3,5,6-tetrafluoro phenmethyl(1R,3S)-3-(2,2-dichloro ethylene)-2,2-dimethyl cyclopropane carboxylic ester and 2,3,5,6-tetrafluoro-4-methoxymethyl phenmethyl-3-(3,3,3-trifluoro-1-allyl)-2,2-dimethyl cyclopropane-carboxylic acid ester. An insect pest prevention and control active compound with more superior physicochemical properties is directly dissolved or emulsified in the dispersing medium, and is prepared into a spray, so that the medicinal effect and environmental friendliness of the spray are improved. The invention further discloses a sanitary insect pest control spray which has an aging indicating effect. An indicator is added into the spray, so that the effect lasting time of a liquid medicament can be indicated intuitively.
Description
technical field [0001] The invention relates to a spray for preventing and controlling sanitary pests, belonging to the technical field of chemical industry. technical background [0002] At present, relatively mature volatile mosquito repellent preparations at room temperature, the active ingredients are mostly plant extracts such as citronella oil, mugwort oil, eucalyptus oil, peppermint oil, camphor oil, or DEET, butylacetamide, etc. Chemically synthesized ingredients such as ethyl propionate (BAAPE). These traditional mosquito repellents often only have a repellent function to mosquitoes, and their duration is relatively short. In order to overcome this defect, people have developed a room temperature volatile pest control agent containing the compound shown in the figure below as an active ingredient, which not only has the effect of repelling mosquitoes, but can even knock down and kill mosquitoes. The active ingredient has the advantages of stronger biological effic...
