What is Carbaryl?
Carbaryl was introduced commercially in 1958 and is used today chiefly as an active ingredient in pesticide products. The most well known carbamate products are those manufactured under the brand name Sevin, trademark of the Bayer Company. Carbaryl is a white crystal-like solid that is ranked third among the most used pesticides in the US.
Target Pests
Carbaryl controls over more than 100 different kinds of insects and is appropriate for use in home gardens, commercial agriculture, forestry and land-range protection. It can be used on cotton, fruit, nuts, shade trees, food crops, ornamentals, and even on poultry, pets, and livestock where necessary.
Mode of Action
Carbaryl and other carbamate products work as reversible inhibitors of the enzyme acetylcholinesterase. What this means in everyday language is that when a pest comes in contact with the chemical through skin absorption or digestion, the carbaryl directly attacks the nervous system, causing death.
Carbaryl Favored for Food Crops
Carbamate insecticides have been somewhat of a breakthrough because they do not persist on food crops in the same way as chlorinated pesticides. Rather, carbaryl residue is detoxified and eliminated quickly in vertebrates while remaining toxic to insects. For this reason carbaryl is a favorite for use on food crops in the United States.
Toxicity
Carbaryl is labled as moderately to very toxic and carries the signal word WARNING on its label. It is capable of killing both target pests and some beneficial insects, like honeybees.

White grubs (the larvae of various scarab beetles) are common pests of turf in the Northeast. Four species of grubs often cause problems in New England: the European chafer ( Rhizotrogus majalis ), the Japanese beetle ( Popillia japonica ), the oriental beetle ( Exomala orientalis ), and the Asiatic garden beetle ( Maladera castanea ). The life cycle of each of these species is relatively similar (adults fly in early summer and lay eggs in late June to late July; larvae feed on turf roots from early July through mid autumn and again in the spring; pupae are present in the soil for a week in mid June to mid July; and adults emerge early the following summer to complete the cycle). The life cycle of the European chafer occurs about two weeks earlier than that of the other species in any given location.
