Dursban is an active ingredient that has been banned commercially in the United States because it is not as safe as current pest control products. Here at Solutions Pest & Lawn we sell professional-quality pesticides that are safer and just as effective as dursban.

On this page we will tell you a little about this active ingredient and its history and you can also shop one of the few dursban based products we still have in stock.

What is Dursban?

Dursban (chemical name chlorpyrifos) is an insecticide active ingredient which comes from a class of chemicals known as organophosphates which are widely used in agriculture to protect crops from pests. Aside from agriculture, dursban was also a common ingredient in pesticide sprays for residential and institutional use, including the sprays used by pest control professionals. In residential settings, dursban would typically be used to treat termites and for lawn care.

Organophosphates were originally discovered in 1800s, but their effects on animals weren't found out until the early 1930s. That effect was put to use in World War II, when organophosphates were used as nerve gas agents in chemical weapons. Dursban, and other organophosphates, are highly toxic to mammals, with a chemical characteristic that leads them to dissipate very slowly once introduced to the body. Dursban was introduced in 1965 as a pesticide for commercial and residential by the Dow Chemical Company.

How Dursban Works

Dursban’s mode of action is achieved by interrupting the electrochemical process that nerves use to communicate with muscles and with one another. A key chemical in communication between synapses is acetylcholine, a type of chemical called a neurotransmitter. This chemical is produced by the body, used to "fire" the neuron, and then is inhibited by an enzyme called cholinesterase.

Dursban alters cholinesterase, preventing it from inactivating acetylcholine. As the acetylcholine builds up, the muscles of the body become over-stimulated, leading to paralysis and death.

Where Dursban Was Used

Dursban is generally used as an active ingredient in lawn care and pest control products to eliminate ants, cockroaches, aphids, fleas, wasps, and spiders, and other agricultural pests.

Why Dursban Was Taken Off Shelves

Dursban insecticide was "banned" by the EPA from commercial and residential use in 2002.  This was because the EPA reportedly found Dursban to pose serious health risks to women and children through pesticide residue present in food. Dursban and other similar pesticides would be phased the market beginning in 2001 though there are still some products that are sold commercially which contain the active ingredient. Residential use of dursban is not allowed.
