Mosquitoes--they bite, they spread diseases and they are dangerous. The most effective way of fighting mosquitoes are insecticides. The problem is that as the years go by, mosquitoes grow increasingly resistant to the active ingredients supplied and their effect. The solution? An insecticide which kills mosquitoes with a completely different mode of action--chlorfenapyr.

On this page you can shop our entire inventory of products which contain chlorfenapyr. Learn a little about the history of this product and why it works so effectively to treat various problem pests such as mosquitoes.

What is Chlorfenapyr?

Chlorfenapyr (chemical name: 4-Bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethyl-1H-pyrrole-3-carbonitrile) is a new age pesticide active ingredient that has gained popularity in recent years and is derived from  microbes known as pyrroles. This class of chemical that has proven particularly effective against insects that have gotten resistant to other insecticides. Chlorfenapyr is regarded as a pro-insecticide which means it is metabolized into an active insecticide after entering the host.

Chlorfenapyr was developed initially by BASF. The active ingredient was registered to the EPA in January, 2001 for use on non-food crops in greenhouses and then in 2005 was approved for use on food crops as well.

How Does Chlorfenapyr Work?

Chlorfenapyr mode of action results in the target insect not being able produce enough energy to survive at the cellular level. This unique mode of action is called METI-mitochondrial electron transport inhibitor. Insects develop little resistance because it takes 24-48 hours for chlorfenapyr to result in death (allowing them to pass on susceptible genes to the next generation). Chlorfenapyr is activated inside the insect (metabolized into an active insecticide after entering the host).

The insect makes contact with the chlorfenapyr and then the product spreads throughout the insect's body but it doesn’t take effect immediately. The chlorfenapyr then metabolizes and spreads throughout the insect's body and the mitochondria which gives cells their energy. This separates chlorfenapyr from most common insecticides like pyrethroids because those insecticides target the nervous system.
