spider bite in the United States, the two spiders whose bites are most likely to cause a serious reaction are the black widow spider(Latrodectus mactans) and the brown recluse spider(Loxosceles reclusa). Signs and symptoms are associated with the effects of injection of the venom and include pain at the injection site, weakness, muscle pain and cramps, elevated blood pressure, and restlessness. Bites by these spiders must be treated promptly and effectively. First aid is the same as that for a snakebite and includes the following:

1. Wash the wound with soap and water and apply a clean dressing.

2. Apply a constricting band between the area of the bite and the heart.

3. Keep the person calm and transport him to the hospital or medical facility as soon as possible.

4. If swelling becomes apparent, apply a cold compress to the area.
