Methiocarb is a carbamate pesticide (an acetylcholinesterase inhibitor) which is used as an insecticide, bird repellent, acaricide and molluscicide since the 1960s. Methiocarb has contact and stomach action on mites and neurotoxic effects on molluscs. Seeds treated with methiocarb also affect birds. Other names for methiocarb are mesurol and mercaptodimethur.

Due to its toxicity, methiocarb approval as a plant protection product has been withdrawn by the EU effective 2020.
