Description:

A chitin synthesis inhibiting insecticide used to control chewing pests.

Short and long-term exposure to low concentrations of chlorfluazuron in the diet was without serious consequences in animal studies. The only consistent finding was an increase in cholesterol levels. Chlorfluazuron did not cause birth defects in laboratory animals.
There is evidence to indicate that chlorfluazuron persists and bio-accumulates in the body. In rats, high levels of chlorfluazuron residues were deposited in fat and depletion was slow, with a depletion half-life of approximately 42 days. Goats and hens secreted chlorfluazuron into milk and egg yolk, respectively. If given in the diet of food-producing animals, there is a significant potential for accumulation and retention of residues in the fat and for excretion in milk.
As chlorfluazuron is used in subterranean termite baiting stations, public exposure is unlikely to occur. However, due to its persistent and bio-accumulative nature, care needs to be taken not to misuse the chemical.

Mode of action:

Chlorfluazuron is a benzoyl phenyl urea insecticide, which requires ingestion by target pests to be efficacious. It is an insect growth regulator inhibiting the synthesis of chitin, a vital part of the exoskeleton of insects.

Chlorfluazuron disrupts the formation of chitin at the time of moulting, resulting in the failure of the termite to complete the moulting process, and eventually kills the affected termites.

Chlorfluazuron is found in several insecticide products used in subterranean termite baiting stations.

Toxicity:

In laboratory animals, chlorfluazuron had very low acute toxicity if ingested, inhaled or exposed on the skin. It was slightly irritating to the eyes but did not cause skin irritation or allergic reactions when applied to the skin. Chlorfluazuron was absorbed only to a limited extent when swallowed and excreted mainly in the faeces.
