Contrary to popular conception, latrodectism is very rarely fatal to people though domestic cats have been known to die with convulsion and paralysis. If, however, there is a substantial dose, a bite can cause latrodectism. The main symptoms are generalized muscle pain, stomach cramps, nausea and vomiting. Neither puncture marks nor redness are necessarily seen.

A few people go on to have widespread symptoms. Changes in adrenaline can lead to mild increase in blood pressure and pulse. Non-specific features of latrodectism include headache, nausea, vomiting and feeling ill and weak. Symptoms may wax and wane over the next one to four days. Rarely, patients may feel unwell for up to a week. Very rarely, untreated patients report ongoing bite site pain that last weeks or months.

During pregnancy the pain and abdominal cramps may be confused with other conditions. A case of preterm labor initiated by a redback spider was relieved by antivenom. Early medical reports of latrodectism were described in men using outhouses. The genitals were often the site of the bite. No direct injury to site is reported. Spider venoms are a complex collection of toxic agents. Unique to the widows is latrotoxin.

The venom acts on nerves causing the massive release of the neurotransmitters acetylcholine, norepinephrine, and GABA. There are no tests required to diagnose widow spider bites, or latrodectism symptoms. The diagnosis is clinical and based on historic evidence of widow spider bites. Diagnosis is obvious in most people reporting contact with a Latrodectus spider. However, without a spider, either through inability to communicate or unawareness, the diagnosis may be missed as symptoms overlap with a variety of other serious clinical syndromes such as tetanus or acute abdomen. People who have been bitten by a black widow spider are recommended to seek professional medical assistance for symptoms. Symptoms self-resolve in hours to days in a majority of bites without medical intervention.

Medical treatments have varied over the years. In the United States, where antivenom is rarely used, there have been no deaths reported for decades. Despite frequent reference to youth and old age being a predisposing factor it has been demonstrated that young children appear to be at lowest risk for a serious bite, perhaps owing to the rapid use of antivenom. Bites from Latrodectus occur usually because of accidental contact with the spiders. The species are not aggressive to humans naturally, but may bite when trapped.

As such, bite incidents may be described as accidents. Reports of epidemics were associated with agricultural areas in Europe in the last two centuries. Conversely, redback and North American black widows live in proximity with people and several thousand black widow bites are reported to Poison Control in the United States each year. About 800 are reported by medical personnel. Amongst those 800 bites only a dozen had major complications and none were fatal. In Perth, Australia, for example there were 156 bites in children from redback spiders over 20 years. Twice as many boys were bitten as girls, mostly toddlers.
