Prevention
Efforts to prevent bites include clearing clutter and the use of pesticides.OSHA recommends that workers take following measures to prevent spider bite:

Wear a long-sleeved shirt, hat, gloves, and boots when handling boxes, firewood, lumber, rocks, etc. Inspect and shake out clothing and shoes before getting dressed. Use insect repellents, such as DEET or Picaridin, on clothing and footwear. Management
Most spider bites are harmless, and require no specific treatment. Treatment of bites may depend on the type of spider; thus, capture of the spider—either alive, or in a well-preserved condition, is useful.Treatment of spider bites includes washing the wound with soap and water and ice to reduce inflammation. Analgesics and antihistamines may be used; however, antibiotics are not recommended unless there is also a bacterial infection present. Black widow post-envenomation treatment seeks to control resulting pain and nausea. In the case of bites by widow spiders, Australian funnel-web spiders, or Brazilian wandering spiders, medical attention should be sought immediately as in some cases the bites of these spiders develop into a medical emergency. Antivenom is available for severe widow and funnel-web envenomation. Necrosis
In almost all cases, recluse bites are self-limited and typically heal without any medical intervention. Recommendations to limit the extent of damage include elevation and immobilization of the affected limb, application of ice. Both local wound care, and tetanus prophylaxis, are simple standards. There is no established treatment for more extensive necrosis.
Microvenular hemangioma  is an acquired benign vascular tumor that presents as an asymptomatic, slowly growing, 0.5- to 2.0 cm reddish lesion on the forearms or other sites of young to middle-aged adults. See also
