ABSTRACT:
A trash can device, comprising an upper housing and a lower housing. The lower housing is sized to fit within the upper housing. A chemical disk containing both pesticide and deodorizing agents is located within the lower housing. The lower housing has lower housing circumference openings. The upper housing has upper housing circumference openings. The lower housing and upper housing are coaxially rotatable to selectively bring the upper housing circumference openings into alignment with the lower housing circumference openings to allow selective release of the pesticide and deodorizing agents or prevent premature release thereof. The upper housing may have a lid having a lid flange for use upon a trash can having an upper lip, such that the device covers the trash can with the lid flange extending over the upper lip of said trash can.
