A mosquito coil An<unk>  (also commonly called "bug spray") is a substance applied to skin, clothing, or other surfaces to discourage<unk> s (and arthropods in general) from landing or climbing on that surface.<unk> s help prevent and control the outbreak of<unk> -borne (and other arthropod-bourne) diseases such as malaria, Lyme disease, dengue fever, bubonic plague, river blindness, and West Nile fever. Pest animals commonly serving as vectors for disease include<unk> s such as flea, fly, and mosquito; and ticks (arachnids). Some<unk> s are<unk> icides (bug killers), but most simply discourage<unk> s and send them flying or crawling away. Nearly any would be fatal upon reaching the median lethal dose, but classification as an<unk> icide implies death even at lower doses.
