Chlorfenapyr

Flying and biting pests like mosquitoes are not only irritating but have the potential to spread harmful diseases. In recent years, flying pests have grown increasingly resistant to certain commonly used active ingredients, which is why Chlorfenapyr was developed with a different mode of action for control.

On this page, we will discuss Chlorfenapyr, its benefits, how it works, and how safe it is to use. You can also shop our top-recommended product, which contains Chlorfenapyr.

What is Chlorfenapyr?

Chlorfenapyr is a newly developed active ingredient derived from microbes known as pyrroles. Chlorfenapyr has proven to be particularly effective against insects that are resistant to commonly used insecticides. Unlike typical pesticide active ingredients, Chlorfenapyr uniquely activates itself once it enters the host.

Chlorfenapyr is commercially used for termite control and crop protection against a variety of insect and mite pests. It is mainly used in the fight against disease-carrying mosquitoes worldwide.

How Does Chlorfenapyr Work?

Chlorfenapyr hinders the target insects' ability to produce energy at the cellular level. Chlorfenapyr fights against resistance development because it takes 24 to 48 hours for Chlorfenapyr to result in death (allowing exposed insects to pass on susceptible genes to the next generation). Chlorfenapyr is activated once ingested and metabolized by the insect.

Benefits of Chlorfenapyr

Chlorfenapyr works quickly to kill target pests, and its unique mode of action makes it less likely for insects to develop a resistance to the chemical. Chlorfenapyr-based products are usually non-repellent and have a long-lasting residual of 14 to 21 days.

Drawbacks of Chlorfenapyr

Insects do not die instantly from Chlorfenapyr, as it may take a few days for the product to kill the pest totally. Certain formulations of Chlorfenapyr need to be agitated frequently during applications so that they don't settle or clog the sprayer.

Is Chlorfenapyr Safe?

There are few known risks to humans from the chemical at this time. Always use products containing Chlorfenapyr as directed on the product label.

When handling products containing imidacloprid, it is best to err on the side of caution and wear gloves and protective clothing when spraying. Please use the product according to the instructions on the label and adhere to the safety measures on the label when applying it.

What To Expect

After applying Chlorfenapyr, target insects should die within 72 hours. The active ingredient has a residual effect of 14 to 21 days.

When the insect consumes Chlorfenapyr, it doesn’t take effect immediately. Instead, it activates after being metabolized by the insect and spreads throughout the insect's body, depleting the insect of its energy.
