A product which has had tremendous success in Korea. It's natures own insect controller and is harmless to humans and pets. The active ingredient is Natural Pyrethrins - Natures own Pesticide
All Biomist aerosols
- Use natural Pyrethrum derived from plant extracts.
- Are non-irritant, environmentally friendly and contain no chloro-fluoro carbons.
- Are non-allergenic and non-toxic.
- Biomist aerosols have passed rigorous testing by environmental and pesticide authorities (K-FDA) in Korea.
- Biomist dispenser dispenses a constant amount of Pyrethrum into the air and it is this action that keeps insects away by creating an invisible shield.
- Pyrethrum is the most effective insect deterrent known and one of the safest on the market.
- It's effectiveness against a wide range of insect pests including, MOSQUITOES, FLIES, COCKROACHES, WASPS, FLEAS, BUGS, and ANTS.
- Insects are repelled by Pyrethrum at very low dosages. The insect need only detect the smallest amount of Pyrethrum (ppm) for it to want to escape.
- Should the insects enter the sprayed area it will be knocked down. Pyrethrum also disturbs the insect from its hiding place exposing them to its spray. It's the most effective and safe method of getting rid of unwanted insects available on the market.
- Pyrethrum is extracted from a flower in the Chrysanthemum family and is purified for use as an insect controller.
- Natural Pyrethrins are the safest pesticide known to man. In Europe Pyrethrum is taken as an oral medicine to control stomach and intestinal worms.
- Insects do not become resistant to Pyrethrins because each batch is different.
- Pyrethrins degrade in sunlight to 6% in only 2 hours. No buildup of toxicity.
- Pyrethrins are very expensive hence large commercial concerns use synthetic Pyrethrins called Pyrethroids which are much cheaper.
- Only the first 4, approximately, of the Pyrethrins' pheromones can be
synthesized.
- Insects rapidly become resistant to Pyrethroids. Only natural Pyrethrins have a repellency capability. This can not be
synthesized.
- Pyrethrins repel and kill Flies, Mosquitoes, Cockroaches, Fleas, all other insects.
- Pyrethrins affect tropical fishes. So be careful on installation.
- Biomist formulation use synergist (PBO, Piperonyl Butoxide) which help in the repellency and killing capability. This combination of Synergist makes Biomist Natural Insect Killer not only one of the safest in the world but also one of the best.
- Biomist Insect Killer can be used in the home or work place without danger to people or pets. In business involved in food preparation, storage or transport. In horticultural areas, keeping plants free from pests. In farm yards, livestock can be safely protected from irritating and disease carrying pests. At picnics or BBQ keeping flies and mosquitoes away. In schools and hospitals Biomist Natural Insect Killer reduces the risk of insect carrying infections
Under practical conditions, pyrethrins are the least toxic to mammals of all the insecticides currently is use. Pyrethrum has been used orally as an anthelmintic in some areas for many years with no apparent ill effects. Pyrethrum
formula is recommended for use around exposed foodstuffs.
In the united states, under the Miller Amendment of the Federal Food, Drug and Cosmetic Act (1955), a limited number of chemicals is exempted from the requirement of a tolerance under section 408, when applied to growing crops. Pyrethrum is one of the few insecticides so exempted.
(Mammalian toxicology of pyrethrum, Oct.1973 ed., Pyretrhrum Post, Vol.12/No2)
Humans, both children and adults, are reported as having been treated, with excellent results against a variety of intestinal worms.
(B.H. McLellan, Anthelmintic Pyrethrum - A Literature Review, The Pyrethrum Bureau, Nakuru, Kenya)
Aerosols containing Pyrethrum and a Synergist such as Piperonyl Butoxide are still a favored method for controlling Mosquitoes, Houseflies and other flying insects in homes.
(Lee, J., Aerosol insecticide formulation-Review of recent development, Pyrethrum Post 10, Vol.2, pp9-13, 1969)
Pyrethrum sprays applied directly to the skin of livestock have for several years been a popular methods for protecting the animals from attack by biting flies.
(Casida, J.E., Pyrethrum: The Natural Insecticide, Academic Press, New York and London, 1973)
Pyrethrum controls certain insects as effectively and more safely than most of the currently used synthetic organic insecticides. There is no evidence of harm to humans, domestic animals, or wildlife, when used as directed.

All the products listed contain Pyrethrins and Piperonyl Butoxide as the sole active ingredients. They are registered for application by automatic dispensers operating for 24 h/day, for use in occupied area including restaurants, hotels, motels, hospitals, schools, nursing homes, and food preparation areas. Labels specify that these products should not be used in nurseries and that automatic dispensers should not be places directly above food preparation surfaces. Most labels specify that 1 automatic dispensing unit is appropriate for 170 m3 of free flow air space.
The application rates have been listed as well. As the amount of Pyrethrins and application rates vary between formulations, the total amount of Pyrethrins released every 24 h (dose) has been calculated to allow the products to be compared. The total amount of Pyrethrins released by these products ranges from 51 to 95 mg per day. This is higher than the proposed 24 h dose of the Biomist Natural Insect Killer Registered Korean product, which is only 48.6 mg per 24 h.
USA Environmental Protection Agency (EPA) Requirement
Maximum Application Rate: 0.005 lbs Pyrethrins/1000 feet2/day
0.08 mg Pyrethrins/liter/day
80 mg Pyrethrins/m2/day
Sites: General indoor sites, such as schools, hotels,
kitchens, child care centers, dormitories, Hospitals,
health care centers and nursing homes, Eating
establishments - restaurants, mess halls and
cafeterias.
Use restrictions: Do not use in nurseries or rooms where infants, ill or aged persons are confined.
Do not place application devise directly over or within
8feet of exposed food or food preparation areas or
utensils.
Comparison of the maximum application rate for
Biomist Natural Insect Killer and US EPA requirement
Dose Rate for Biomist : 48.6 mg Pyrethrins /24 h
Maximum application rate for Biomist:
One applicator/50 m3 = 0.972mg (48.6/50) Pyrethrins/m3/day
= 1% of the maximum rate of US EPA
One applicator/170 m3 = 0.286 mg (48.6/170) Pyrethrins/m3/day
= 0.4% of the maximum rate of US EPA
An Biomist dispenser when used in accordance with the instructions dispenses approximately 30mg of solvent, propellent and Pyrethrum into the atmosphere about every 8 minutes. Of the 30mg dispensed only 0.9% is the active substance pyrethrum. Therefore the total amount of pyrethrum dispensed into the environment every 8 minutes is : 30/1000 x 0.9/100 = 0.00027g
This equates to approximately 0.002025g per hour (0.00027/8 x 60).
In a worse case scenario where the dispenser is operating in a small room of say 60 cubic meters then the concentration levels could build up as follows : 0.002025/60 = 0.00003375 g/m2 in 1 hour
Most countries set safety levels for natural pyrethrum concentration as 5mg/m2 which is 0.005g/m2r (Worksafe Exposure Limits, TWA). Worksafe Exposure Limit is around 150 times higher than what the Biomist Dispenser will build up in 1 hour, which means extremely safe to human. In addition, natural pyrethrum degrades rapidly in sunlight to 6% within 2 hours.
A 5 second burst of an aerosol can, by manual spraying, will take an Biomist dispenser 1.3 days to dispense, making the system of Biomist dispenser and aerosol, one of the safest systems in the world and definitely one of the most environmentally friendly pesticide systems known to man.
Persistence of residues after application in indoor sites
Pyrethrins have low persistence in the environment due to their instability in the presence of natural sun-light. The photolytic half-life of the pyrethrins is 11.8 h and there is >90% degradation after 40 hours, forming harmless breakdown products such as carboxylic acid and CO2. Studies have shown that photolysis of pyrethrins occurs in indoor as well as outdoor environments. For example, It was demonstrated that Pyrethrins are not persistent in a typical domestic environment consisting of a room in an apartment in the presence of diffuse natural sunlight from a single window. They found that there was rapid deposition of insecticide following a single application by aerosol spray. The initial concentrations of 55 to 300 micrograms/m2 were reduced to 15 - 60% of the starting concentration in air (20%), within half an hour.
Analysis of the pyrethrins deposited on exposed surfaces showed a steady decline in pyrethrins, with a 50% reduction in 24 hours follow by a 90% reduction of total pyrethrins in 48 hours.
