Your snappy message. These are jet-black spiders with red, yellow or orange markings on the underside of the abdomen, often in the shape of an hourglass. They spin a somewhat irregular web in corners and spots in homes, garages, woodpiles and ground cover. If bitten, symptoms include pain, muscle cramping, headache, nausea, vomiting, and anxiety.
Treatment is aimed at relieving pain and relaxing muscles.
Take warm bath for mild cramps See Dr. for shortness of breath or extreme pain. This spider varies from dark brown to light tan with a violin shaped dark area on its back. The bite may appear as a bruise with a small blister in the center. It may look like a bull's eye or halo. The blister can break and leave an open sore, which can enlarge, contain pus, and then turn bluish-black and crusty.
