Methoprene IGRmethoprene

Heavy infestations from ants and cockroaches are usually very difficult to control because even after killing all the adult bugs, there are hundreds to thousands of eggs that have been laid and will soon hatch out a new generation of insects. However, there are products which address the egg issue and stops the cycle from continuing. These are known as insect growth regulators. One such active ingredient in IGRs is known as methoprene.

On this page you can find out more about methoprene, a popular active ingredient for insect growth regulators such as Precor. We will cover how it works and why it is so effective. Here you can also shop the insecticide products we have in stock which contain methoprene

What Is Methoprene?

Methoprene (Chemical name: 1-methylethyl (E,E)-11- methoxy-3,7,11-trimethyl- 2,4-dodecadienoate) is an active ingredient used to control insect invasions such as cockroaches, ants and mosquitoes.  Methoprene is not actually an insecticide but rather belongs to the class of insecticides known as insect growth regulators or IGRs for short. IGRs like methoprene are used to prevent or disrupt the life cycle of insects in the egg and larvae stage of development.

Methoprene comes in two different forms called s-methoprene and r-methoprene, and s-methoprene is the one which behaves like an important juvenile hormone in insects and acts as a form of birth control by not allowing the egg to mature.

In its original form, methoprene is an light brown to amber colored liquid that gives off a fruity odor. Methoprene was first registered to the EPA in 1975 and s-methoprene was later registered in 1985. It’s a main ingredient in popular IGR brands such as Precor and Altosid.

How Methoprene Works

As mentioned earlier, methoprene does not kill insects, but acts as a growth regulator via imitating the natural juvenile hormone within the insect. The juvenile hormone must be absent in order for the larvae to change from pupa to an adult. This artificial juvenile hormone stays inside the egg and prevents the life cycle from continuing.

Methoprene can result in a number of different effects ranging from adult sterility, physical body changes, water loss and other complications which can result in death.

How Methoprene is Used

Methoprene products are used on a variety of indoor sites including homes, offices, warehouses, restaurants, hospitals, and greenhouses. Commercial formulations of the insecticide include aerosols, liquids, and impregnated materials (i.e., bait stations)

 

Methoprene’s can successfully target and regulate fleas, ticks, ants, roaches, bed bugs, mosquitoes and other stored product pests.

 

How Safe Is Methoprene?

According to the EPA, methoprene is classified as having low toxicity. Methoprene can cause slight irritation if it gets into a person’s eyes or lungs. If you touch it, methoprene can cause mild or moderate skin irritation. However, in several studies where methoprene was applied to the skin of laboratory animals, no effects or irritation were noted.

 

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).
