Disclosed herein are spatial insect repellent compositions comprising pyrethrins and about 5% to about 20% by weight p-menthane-3,8-diol.

Spatial insect repellent compositions

A device for dispensing an air treatment chemical includes a housing having an inlet for permitting air to enter into an interior space of the housing and an outlet for permitting air mixed with air treatment chemical to exit the interior space of the housing. A substrate positioned within the housing bears the air treatment chemical. A power supply mounted within the housing powers a motor mounted within the housing. The motor is connected to an impeller mounted within the housing. The impeller moves air from the inlet adjacent the substrate to mix the air treatment chemical into the moving air and deliver the mixture of air and air treatment chemical through the outlet to outside of the housing. The housing includes a transitional body defining a convergent-divergent channel for compressing the mixture at the converging section and expanding the mixture at the diverging section.

Disclosed are pyrethrin-based insect control compositions which have been formulated to reduce wick clogging. An acetylenic hydrocarbon having at least two terminal alkyne groups, such as 1,8-nonadiyne, together with an antioxidant such as dilauryl thiodipropionate, are used to reduce clogging caused by components of pyrethrum extract.
