When it comes to pest issues and the damage they can bring to materials and property, often it is not the adult phase of the insect to be the most worried about, but in fact it is the larvae which inflicts the most damage. This is especially the case for moths, boll weevils and caterpillars. Eliminating these pests can be tough and that is why the active ingredient diflubenzuron is so sought after by pest control professionals for its ability to kill such pests and also act as an insect growth regulator so such pests don’t grow to become destructive larvae.

On this page we will share with you some background information on diflubenzuron, a popular active ingredient in a number of different insecticide products we carry. We will cover its origin and why it is so effective. Here you can also shop the insecticide products we have in stock which are based with diflubenzuron.

What Is Diflubenzuron?

Diflubenzuron is an acaricide/insecticide used to control a variety of leaf eating larvae of insects which consume upon agricultural, forest and ornamental plants. This active ingredient is primarily used as an insect growth regulator on gypsy moths, mosquito larvae, and rust mites among others. Diflubenzuron was first registered as a pesticide in the U.S. in 1976.

In agricultural settings diflubenzuron is used to protect cattle, citrus, cotton, mushrooms, ornamentals, standing water, forestry trees and in programs to control mosquito larvae and gypsy moth populations. Diflubenzuron comes in a number of different formulations such as a soluble concentrate, flowable concentrate, wettable powder and in pellet or tablet form. Diflubenzuron is applied by airblast, aircraft and hydraulic sprayers.

How Diflubenzuron Works

The mode of action of diflubenzuron involves inhibiting the production of chitin which is used by an insect to build its exoskeleton. The chitin synthesis inhibitors interfere with the normal synthesis of insect exoskeletons during molting or at hatching of eggs. It triggers insect larvae to molt early without a properly formed exoskeleton, resulting in the death of the larvae. In other words, it causes a sort of premature birth where the larvae will not be able to survive.

How Diflubenzuron is Used

Diflubenzuron is a stomach and contact poison which acts by inhibiting the production of chitin (a compound that makes the outer covering of the insect hard) and so interferes with the formation of the insect's cuticle or shell.


Diflubenzuron is used to control a wide range of insects which like to eat plants and leaves in forestry, woody ornamentals and fruit. It controls some major pests in cotton, soy beans, citrus, tea, vegetables, rice, peanuts, tree nuts and mushrooms. Diflubenzuron also controls larvae of flies, mosquitoes, grasshoppers and migratory locusts. It is also used to control ectoparasites in sheep, specifically lice, fleas and blowfly larvae. Due to its selectivity and rapid degradation, as well as high solubility in water and soil, diflubenzuron is less harmful to beneficial insects and thus a good candidate for integrated pest management (IPM) programs.


How Safe Is Diflubenzuron

According to the EPA, Diflubenzuron is regarded as having low acute toxicity. The people most at risk of being exposed to diflubenzuron are handlers (mixers, loaders, and applicators) during and after normal use of applications in agricultural and other settings.


As a precaution, we recommend following safety procedures found on the instruction label and wearing the proper protective equipment (long sleeve clothing, gloves, breathing mask and protective eyewear).
