The element sulfur is used in matches, insecticides, and fungicides. Most nets are impregnated with pyrethroids, a class of insecticides with low toxicity. Arsenic was also used in various agricultural insecticides and poisons. There are no reports indicating that chronic intoxication from pyrethroid insecticides causes motor neuron disease. Endophilic mosquitoes are readily controlled by indoor spraying of residual insecticides. Sublethal doses of insecticides (i.e. imidacloprid and other neonicotinoids) affect bee foraging behavior.
