Pyrethrum is a botanical insecticide produced primarily from the flowers of Tanacetum cinerariaefolium, which is a species of the chrysanthemum plant family. It is found mainly in tiny oil-containing glands on the surface of the seed case in the tightly packed flower head and is the plant’s own insecticide that has evolved to keep insects away. Pyrethrum is made up of six complex chemical esters known as pyrethrins which work in combination to repel and kill insects.
The natural pyrethrins are contact poisons which quickly penetrate the nerve system of the insect. A few minutes after application, the insect cannot move or fly away. But, a "knockdown dose" does not mean a killing dose. The natural pyrethrins are swiftly detoxified by enzymes in the insect. Thus, some pests will recover.

To delay the enzyme action so a lethal dose is assured, organophosphates, carbamates, or synergists may be added to the pyrethrins.
Pyrethrin has been used effectively to control insects for decades. It decomposes rapidly in the environment, making it an excellent choice for controlling pests.
Pyrethrin is one of the safest insecticides known, as it has a very low Mammalian toxicity, and is rapidly metabolized if accidentally swallowed by warm blooded animals.

Pyrethrin has been extensively studied from a toxicology viewpoint. It is low in acute toxicity to humans and other vertebrate animals, is non-carcinogenic and causes no adverse reproductive affects.
Pyrethin has flushing action, it disturbs insects so that they move out of their hiding places and expose themselves to the insecticidal spray. Pyrethrum has greater 'flushing' power than any other commercial insecticide. Against insects, it has a very rapid paralytic action, knocking them down followed by kill. Pyrethrum repellents insects at very low concentrations, a property used in the protection of stored grain, the preparations of insect resistant packaging, and in deterring mosquitoes, both by spray-on repellents and mosquito coils. In addition, the smoke from Pyrethrum-based mosquito coils will inhibit mosquitoes from biting. Pyrethrin is commonly used as a post harvest treatment for fruits and vegetables especially during shipment and is popular as a non-residual household insecticide spray.

Pyrethrum rapidly degrades by sunlight into harmless breakdown products, but at the same time it can be safely stored for years in suitable containers.
Despite its long history of use, very few cases of insect resistance to Pyrethrum have been discovered, and these have mainly arisen as a result of cross-tolerance conferred by the insects developing resistance to another insecticide.
Pyrethrum is effective against a wide range of insect pests including mosquitoes, cockroaches, fleas, flies, aphids, etc.

PBO (Piperonyl Butioxide), trade name "Exponent", is an emulsifiable synergist for use in combination with insecticides, especially synthetic pyrethroids, as a tank mix to overcome resistance that pests develop with constant use of insecticides.
PBO is a unique tank additive that restores activity against resistant strains of pests. It acts by inhibiting naturally occurring enzymes that would otherwise degrade the insecticide molecule.
PBO breaks through the insect's defense and its synergistic activity makes the insecticide more powerful and effective. With the high cost of insecticides, PBO effectively reduces the cost per gallon of spray solution by allowing the applicator to use less active ingredient to obtain the mortality rate desired.
Insects are amazingly adaptable, and possess an enzyme system called the mixed-function oxidases (MFO's) that give them the ability to de-toxify and become resistant to many insecticides, especially synthetic pyrethroids. Continual application of pesticides starts the build-up of resistance and thus the efficacy of the spray diminishes. PBO inhibits the action of MFO's and restores the killing power of the insecticide, which results in less expensive and/or more effective pest control. Actual results show that PBO either decreased the cost of pest control since smaller doses are needed, or provided better control of insects where cases of maximum dosages of pesticides without PBO had failed.
Therefore, PBO can PROLONG the usefulness of insecticides by overcoming resistance. Improved control means fewer applications of insecticides, thus providing cost savings as well as environmental benefits.
 

Odor-Mist is a concentrated odor neutralizer that doesn’t just cover odors, it destroys them. Odor-Mist eliminates nitrogenous, sulfurous as well as many other odors. It is also water based so it works well as a spray, on bedding or in automatic insect control systems or other liquid, automatic or metering systems to create a pleasant atmosphere every time they spray.

For automatic insect control systems mix 1 quart per 55 gallons of spray solution, 16 oz. for 30 gallons and 8 oz. for 15 gallons.

These sprays are safe for use in barns and stables, kennels, food processing plants, bakeries and etc. when mixed and used in accordance with label directions.

Material Safety Data Sheets (MSDS) are available on all products.
