There are many instances in pest control where the advantages of natural pyrethrins (which are derived from Pyrethrums) are put to use. These natural pyrethrins have a relatively low possibility of hazards to people and pets over other types of insecticides. They also have very little residual effect. This lack of residual, as strange as it may seem, is a great characteristic for certain types of pest control jobs.
With low toxicity and nearly zero residual, pyrethrins can be used to
safely fog sensitive areas that cannot tolerate higher residual
insecticides. These areas include kitchens, commercial kitchens, schools,
hospitals and other areas where a quick knock-down of targeted pests is needed
without contaminating surfaces in the areas.
Pyrethrins are used extensively in products such as flea
sprays for dogs and cats, total release foggers (bug bombs) as well as fogging
concentrates, fogging solutions. Exciter
is a concentrated pyrethrin product that can be mixed with water and used as a
spray, mist or fog. Food plant fog is a
generic term used for ready to use pyrethrin fogging solutions that contain
approximately 0.50% pyrethrins. This type of fog is usually labeled for
use in commercial food handling establishments, restaurants, homes, schools,
etc., and is sold under different brand names such as BP 50.
