CB-80 is a pyrethrum based aerosol product. It kills a myriad of different pests. So from that perspective, it's moderately toxic. However, because it is partially derived from chrsanthemum flowers, it's also considered a botanical insecticide that is to some degree naturally derived. Pyrethrum as a whole has a very short life span, minutes in some cases. It is used in schools and hospitals on a regular basis.
