Pyrethrins are natural insecticides found in daisy-like Chrysanthemum flowers grown and harvested in Kenya, Africa. Pyrethrins have a low order of toxicity to warm-blooded animals and can be used even in the home with extreme confidence.
When pyrethrins are combined with a synergist like piperonyl butoxide, its "killing power" against insects increases dramatically.The United States Department of Agriculture has stated that synergized pyrethrum "is probably the safest of all insecticides for use in food plants "and that" a pyrethrum formulation is approved for use around foodstuffs".
Pyrethrin may be used with safety in food plants, homes and around animals where more hazardous materials cannot be used. It has a long history of satisfactory use around mammals and birds.
Pyrethrin and the synergists are biodegradable and rapidly disintegrate in sunlight and air, thus assuring you that there will be no excessive build-up of insecticides dispensed in the area being treated. The quantities of insecticides dispensed by the Automatic timed-Aerosol Dispenser are minimal or mere trace quantities, when compared with officially established standards of safe human tolerance.
REPELLENT AND INSECTICIDAL PROPERTIES
Pyrethrin, usually considered only for its knock-down and kill effect, also possesses substantial inherent repellency of insects.
Observations in food establishments demonstrate that flies are not immediately killed but are found more often on windowsills or near doorways, bearing out the observation that pyrethrins are effective repellents, kill slowly due to the low dosage applied and drive the fly to seek the outdoors before dying. In any event, the most noticeable effect after a short period of operation of the automatic timed-aerosol dispenser is the absence of any winged insects of even crawling insects, such as cockroaches, in aerosolized space.

GREATER SAFETY FOR USERS
The safety of an aerosol insecticide from the standpoint of the user depends not only on low toxicity of the active and ingredients, as such, but also on the quantities emitted and the resulting concentration of chemical substances in the atmosphere. In other words, the method of dispensing insecticides has an important bearing on safety.
