Some examples of arthropods are:Insects, including butterflies and antscentipedes and millipedesArachnids, including ticks, spidersCrustaceans, including shrimp, barnacles, and crabs
Rickettsial disease covers a group of diseases caused by the microorganisms. Rickettsiae occupy a position between bacteria and viruses. Most rickettsial diseases are spread to humans by arthropods such as ticks, lice, mites and fleas.
Some do some don't, many of the terrestrial arthropods have spiracles like insects, centipedes and millipedes. Not all arachnids have spiracles but at least some acari have them, for example, ticks.

The West Nile virus (WNV) is an arbovirus spread by mosquitoes that can cause infections in animals and humans. "Arbovirus" refers to a virus that is spread by mosquitoes, ticks, or other arthropods.

Do you mean arthropods? If so, your question needs to be more specific. According to National Geographic, arthropods are the single most diverse group of animals. Among that group, you can find a variety from butterflies to tarantulas to horseshoe crabs to ticks to lobsters. So as far as what arthropods kill, you would have to narrow your focus.
Arachnids include all spiders, scorpions, mites, ticks, harvestmen and sun/camel spiders.
