Aldicarb is a carbamate insecticide which is the active substance in the pesticide Temik. It is effective against thrips, aphids, spider mites, lygus, fleahoppers, and leafminers, but is primarily used as a nematicide. Aldicarb is a cholinesterase inhibitor which prevents the breakdown of acetylcholine in the synapse. In case of severe poisoning, the victim dies of respiratory failure.

Aldicarb is one of the most widely used pesticides internationally, and is also one of the most environmentally toxic. Aldicarb poisoning from agricultural water runoff has led to the destruction of healthy ecosystems and the irreversible poisoning of fertile agricultural land. Poisoning from this pesticide is also believed to be linked to high cancer rates in communities located around the Aral Sea.

Aldicarb is effective where resistance to organophosphate insecticides has developed, and is extremely important in potato production, where it is used for the control of soil-borne nematodes and some foliar pests. Its high level of solubility restricts its use in certain areas where the water table is close to the surface.

In the United States, aldicarb was approved by the USEPA for use by professional pesticide applicators on a variety of crops, including cotton, beans, and others. It is not approved for household use. EPA started limiting the main aldicarb pesticide, Temik 15G, in 2010, requiring an end to distribution by 2017. Discontinuation of the use on citrus and potatoes began in 2012, with a complete phase out of the product expected by 2018. A new aldicarb pesticide named AgLogic 15G, was approved by the EPA in December 2011 and is said to be entering the market in 2015. It will be registered for use on cotton, dry beans, peanuts, soybeans, sugar beets, and sweet potatoes.

Tres Pasitos, a mouse, rat, and roach killer that contains high concentrations of aldicarb, has been illegally imported into the United States from Mexico and other Latin American countries. The product is highly toxic to animals and people, and according to the EPA "should never be used in [the] home."
