Spider bites are usually mild and not very noticeable, with symptoms lasting only a day or a few days. They may appear as a red, inflamed, and sometimes painful bump on the skin, and may go unnoticed. Not all bites are harmful, but those displaying symptoms of infection, allergic reaction, or toxicity may require treatment.
Bites and stings from insects and spiders usually cause pain, swelling, redness, and itching at the site of the sting or bite. Most spider bites only rarely cause serious problems, but they can cause redness, swelling, and pain in the bite area. Some spiders, like the Black Widow, can cause itchy, red wounds that heal within a week.
Brown recluse bites can cause redness, itchiness, pain, and wounds, which can lead to bruising, a blister, an open sore, scarring, rash, fever, nausea, or vomiting. Insect and spider bites often cause minor swelling, redness, pain, and itching, and can last from a few hours to a few days.
Over 50 spiders in the U.S. have venom, and their bites cause reactions that are not serious, including pain or redness at the bite site.

What is early stage necrosis spider bite?
Violin or recluse spider bite. The dermatological features of these spider bites depend on the severity of the bite. In self-healing wounds, the bite site gets no worse than being swollen and red. With more serious bites a ” bull’s eye ” wound may form. This is characterised by a central red swollen blister that is separated from a peripheral bluish region by a white zone of firm swelling. If the bite turns a purplish colour within the first few hours, this usually indicates severe localised tissue death ( necrosis ) may occur. Over days the blister forms a scab, which hardens and falls off to leave behind an ulcerated depression. Healing can take weeks to months.
Interestingly, it appears that bites that become systemic do not also develop necrotic wounds. It is thought that in necrotic wounds the venom is localised in the tissue whereas in systemic reactions the venom is distributed quickly throughout the body without any localised effects.
- Another spider bite. Hobo spider results in dermonecrotic lesions similar to violin/recluse spider bites.
- Yellow sac causes a painful, red, swollen and itchy bite that may produce a slightly necrotic wound that heals without scarring.
- Banana spider has few dermatological features, mainly neurotoxic symptoms.
- Funnel-web causes sudden onset of neurotoxic symptoms, and the dermatological features insignificant in comparison.
- Whitetail spider may cause discomfort and redness but does not cause ulceration or any serious symptoms.
