It has since been made available for household consumers. Read on to learn more fascinating facts about cypermethrin.

What Is Esfenvalerate?

Esfenvalerate (Chemical name:(S)-cyano (3-phenoxyphenyl) methyl-(S)-4-chloro-alpha-(1-methylethyl) benzeneacetate) is a synthetic pyrethroid insecticide known for its low toxicity to mammals and its rapid knockdown of insects. The pyrethroid family of insecticides is widely used in broad spectrum insecticides concentrates. Esfenvalerate is a commonly sought after product by pest control professionals because of its ability to control a wide range of insects and its versatility--esfenvalerate products can often be used both indoors and outdoors in commercial and residential settings.

Esfenvalerate has a low toxicity to humans and is safe to use around pets when it's applied as directed. Because it is a synthetic pyrethroid, it lasts longer than natural pyrethrum and provides long-lasting control and prevention.

Esfenvalerate comes in a number of different formulations--from microencapsulated formulas to liquid insecticide concentrates and aerosols. Whether you are dealing with spiders, fleas, scorpions, or just general preventative pest control, there are few active ingredients which are superior to esfenvalerate.

How Esfenvalerate Works

Esfenvalerate goes to work immediately once an insect has come into contact or ingests the ingredient. The poison interferes with the insect's nerve cells, which leads to paralysis and prevents the insect from performing normal functions like feeding and grooming. It isn’t long before the insect dies from not being able to feed himself.

Esfenvalerate products are used commonly by pest control professionals when tasks with treatment jobs for their clients. Esfenvalerate products can be used outdoors in areas including parks, athletic fields and agricultural sites. You can use cypermethrin to fight pests in food granaries, greenhouses and pet kennels. Esfenvalerate also works well on ornamental trees and shrubs, eliminating pests and preventing further invasions from occurring on them.

Is Esfenvalerate Safe To Use?

When applied properly, esfenvalerate is not hazardous to humans and is actually safe around pets and children AFTER the product has completely dried. As long as the product is not ingested or gets on your skin, you will be fine. When handling cypermethrin products, or any chemical insecticide, it is recommended that you always wear proper protective clothing and safety equipment.


Esfenvalerate is most hazardous in it’s concentrated form. If it is diluted with water, such as is recommended when applying to surfaces and to target insects, it is much safer. However, cypermethrin, like most synthetic pyrethroids, are extremely toxic to fish so you should avoid spraying near bodies of water like lakes and ponds.


Whenever you use any of our products here at Solutions Pest & Lawn, we always recommend keeping children and pets away from the area being treated until the application product has completely dried which usually takes a half hour to an hour. Once dried, children and pets can be brought back into the area and go back to normal behaviors.
