The phylum Arthropoda includes arachnids and insects. Although their bites typically cause only local reactions, some species are venomous or transmit disease. The two medically important spiders in the United States are widow spiders Latrodectus , the bite of which causes intense muscle spasms, and the brown recluse Loxosceles , which may cause skin necrosis. Widow bites usually respond to narcotics, benzodiazepines, or, when necessary, antivenom.
Most recluse bites resolve uneventfully without aggressive therapy and require only wound care and minor debridement. Tick bites can transmit diseases only after prolonged attachment to the host. Treatment of clothing with permethrin and proper tick removal greatly reduce the risk of infection.
Ticks of medical importance in the United States include the black-legged tick, the Lone Star tick, and the American dog tick. The prophylactic use of a single dose of doxycycline for Lyme disease may be justified in high-risk areas of the country when an attached, engorged black-legged tick is removed.
Bites from fleas, bedbugs, biting flies, and mosquitoes present as nonspecific pruritic pink papules, but the history and location of the bite can assist with diagnosis. Flea bites are usually on ankles, whereas mosquito bites are on exposed skin, and chigger bites tend to be along the sock and belt lines.
Antihistamines are usually the only treatment required for insect bites; however, severe mosquito reactions skeeter syndrome may require prednisone. Arthropods comprise a vast invertebrate phylum that includes arachnids those with eight legs, such as spiders, mites, and ticks and insects those with six legs [subphylum Hexapoda], such as mosquitoes, gnats, and flies.
Most arachnid and insect bites are summertime nuisances, but several species' bites are toxic and others are vectors of disease. This article focuses on spider, mite, tick, and insect bites of medical importance. Enlarge Print. Consider methicillin-resistant Staphylococcus aureus infection in a patient presenting with a suspected spider bite.
Many purported spider bites are bacterial pyodermas or other skin conditions. Black widow spider bites should be treated with intravenous benzodiazepines for muscle spasm and narcotics for pain.
Black widow antivenom should be reserved for patients with significant pain that has not responded to conventional treatment with benzodiazepines and narcotics. Wound cleansing and minor debridement are the mainstays for managing necrotic brown recluse bites.
Tick bites should be treated with prophylactic doxycycline mg in a single dose only when an engorged black-legged tick is acquired in a high-risk area for Lyme disease. Antibiotics are effective if given within 72 hours of tick removal. Only two spiders in the United States are considered medically important with regard to bites: the black widow Latrodectus mactans and the brown recluse Loxosceles reclusa.
Most spiders are harmless. Many suspected spider bites are actually caused by other conditions, such as methicillin-resistant Staphylococcus aureus infection. Most genuine bites are single lesions that require only cleansing, cold packs, and a tetanus vaccination booster.

After a person has been bitten, crampy muscle spasms usually occur within an hour in the chest upper extremity bites or the abdomen lower extremity bites. The pain may be intense enough to mimic myocardial infarction or acute abdomen, but it is rarely life threatening and typically resolves within 48 to 72 hours.
Clark's grading system is used to assess bites and determine management Table 2. Black widow spider Latrodectus mactans; ventral view. Muscular pain in envenomated extremity; extension of muscular pain to abdomen if bitten on lower extremity or chest if bitten on upper extremity ; local diaphoresis of envenomation site or involved extremity; normal vital signs.
Clinical presentation and treatment of black widow spider envenomation: a review of cases. Ann Emerg Med. Treatment of widow bites usually involves intravenous benzodiazepines for muscle spasms and narcotics for pain. One amp of antivenom is added to mL normal saline and slowly infused for 15 minutes 1 mL per minute , with the remainder given over one to two hours.
Brown recluse spiders typically have an inverted violin-shaped marking on their dorsal thorax Figure 3. They are unusual in that they have three pairs of eyes instead of the traditional four pairs. In contrast to widow bites, recluse bites usually occur indoors because the spiders often hide in piles of clothing or in dark places behind furniture.
Venom from brown recluse spiders contains sphingomyelinase D, which is thought to be responsible for neutrophil activation and skin necrosis necrotic arachnidism.
Systemic symptoms are rare in the United States, but persons may develop hemolysis, coagulopathy, and a measles-like toxic erythema rash, which responds to prednisone. Management of recluse bites is controversial, and there are no published clinical trials to guide therapy. Most experts believe that overly aggressive bite management does more harm than good, and cutting out the bite site to prevent necrosis is contraindicated.
Antihistamines have been suggested as an unproven adjunctive therapy that poses little risk to the patient. Ticks are vectors of multiple diseases Table 3. Hard ticks latch onto their hosts and feed for days, whereas soft ticks are localized in animal nests. Hard ticks inhabit brushy fields and tall grass where they await potential hosts.

Both stages of ticks can transmit Lyme disease, which manifests as a characteristic bull's-eye rash i.
Ixodes ticks are also capable of transmitting babesiosis, which is a malaria-like protozoal illness, and human granulocytic anaplasmosis.

The American dog tick Dermacentor variabilis is a common hard tick that may transmit Rocky Mountain spotted fever and tularemia Figure 6. The Lone Star tick Amblyomma americanum of the southeast United States is identifiable by a white spot on its shield Figure 7. It is a potential vector of human monocytic ehrlichiosis, tularemia, Q fever, and southern tick-associated rash illness, which is a Lyme-like disease that may produce a circular rash, headache, and fever.
The infectious agent has not been conclusively identified but generally responds to doxycycline. Persons who are bitten develop delayed hives or, in some cases, anaphylaxis after eating beef, pork, or lamb. Adult female Lone Star tick Amblyomma americanum. Tick bites can be prevented by spraying clothes with permethrin, a synthetic insecticide.
Tucking pants into socks, wearing hats, and performing a daily tick check also reduce exposure. Ticks should be removed with a pair of forceps or tick-removal device , grasping the tick as close to the skin as possible. A gentle, steady pull, perpendicular to the skin, without twisting, usually dislodges the tick without leaving mouthparts behind.
Mites are tiny eight-legged arthropods that, in their larval form, cause itchy bites and sometimes transmit diseases, such as scrub typhus overseas and rickettsial pox.
The six-legged larval form is called the chigger, also known as harvest bug or red bug Trombicula spp. The larvae appear on the skin as tiny red specks that crawl until they reach constrictive clothing; thus, bites tend to be located at belt or sock lines. Occasionally, the penis is severely affected, resulting in summer penile syndrome. Chiggers do not burrow into the skin. The same precautions used for ticks are effective for chiggers.
Immediate showering is likely to dislodge most of them. Bites can be treated with antihistamines, cold compresses, calamine lotion, or rubbing alcohol. No treatment has been demonstrated to be particularly effective.
Fleas Siphonaptera are wingless jumping insects that feed on blood. Flea bites are usually from dog or cat fleas Ctenocephalides , which attack humans when their preferred hosts are unavailable.
For example, a common scenario involves a vacationing family returning home to fleas after their pets have been in a kennel. Typical flea bites are pruritic ankle papules, but other sites may be involved after coming in contact with infested areas.
