Do Spiders Bite?
Some spiders such as a yellow sac spider may bite. Spiders are nocturnal, so they are mostly active at night and as they climb they can accidentally come into contact with humans.
Some spiders are more aggressive than others and may bite repeatedly if kept in contact with the skin, either by rolling over on one in bed, or by having one stuck inside your clothing next to the skin.
How to Identify Spiders Bite?
Spider bites may be associated with sharp pain or be painless. Burning at the bite location may occur for 30 to 60 minutes. Occasionally, systemic reactions such as nausea, fever, malaise, stomach cramps, or skin necrosis may occur, but are rare.
Within first 3-8 hours of the initial bite, a reddened area filled with puss may develop. A noticeable eschar (dead skin tissue that may slough off naturally) may form. In most cases it will come off naturally and the wound will heal in a few weeks.
What to do if You Got Bitten by a Spider?
It is important that this wound does not become contaminated with bacteria, causing infection.
Most yellow sac spider bites only form a hardened red bump, which heals in a few weeks.
If you are bitten by any spider, it is critical to capture the spider so that it can be identified.
An ice compress should be applied to bite area to reduce swelling. Clean and sterilize the bite wound and monitor the symptoms.
If systemic reactions occur such as nausea, fever, malaise, stomach cramps, or skin necrosis, or an open sore develops, contact a physician immediately.
There is still some controversy concerning some of the spider bites. Some claim that a yellow sac spider can cause necrotic lesions, while others believe that necrotic lesions attributed to yellow sac spiders are caused by bites from other organisms, health problems, disease, etc.
