Cyfluthrin is a
pyrethroid
A pyrethroid is an organic compound similar to the natural pyrethrins, which are produced by the flowers of pyrethrums (''Chrysanthemum cinerariaefolium'' and ''Chrysanthemum coccineum, C. coccineum''). Pyrethroids are used as commercial and hou ...

Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, i ...
and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of

In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element (chemistry), element – but distinct arrangements of atoms in space. ''Isomerism'' refers to the exi ...

it is highly toxic to fish and
invertebrates
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordate subphylum ...
, but it is far less toxic to humans.
[ It is generally supplied as a 10–25% liquid concentrate for commercial use and is diluted prior to spraying onto agricultural crops and outbuildings.

Safety
In rats, the s are 500, 800 (oral), and 600 (skin) mg/kg.
Excessive exposure can cause nausea, headache, muscle weakness, salivation, shortness of breath and seizures. In humans, it is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, whose urinary excretion half-lives are in a range of 5–7 hours. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantification of cyfluthrin in blood or plasma.
Health and safety risks are controlled by right to know
Right to know is a human right enshrined in law in several countries. UNESCO defines it as the right for people to "participate in an informed way in decisions that affect them, while also holding governments and others accountable". It pursue ...
laws that exist in most developed countries. Cyfluthrin is regulated in the US by the EPA.
