“Brown recluse spider cannot bite humans without some form of counter pressure, for example by unintentional contact that traps the spider against the skin,” the CDC reported, adding that the bite marks typically appear as a “white blister” and can produce localized pain, stinging and injuries.

Yellow sac spiders, which are nocturnal, are found almost everywhere in the U.S., according to the University of California in Davis. This spider is known for the “sac” it builds, often found “in the corners of the walls and ceilings, or behind shelves and pictures,” says the university, which also reported that “it can also be seen running on walls and ceilings in the night, and can drop to the floor quickly on a silken thread if disturbed.”

Yellow sac spiders are usually indoors and are known to bite without first being provoked.

“Typical symptoms of a bite include an immediate stinging sensation, followed by redness and slight swelling. Sometimes a blister may form at the site of the bite, often breaking, leaving a sore that heals over a period of several weeks”, according to the University of California in Davis.

That said, it is important to note that this particular arachnid is not to inject its venom every time it bites, and is not to pierce everyone’s skin.

Symptoms of a brown widow bite may include muscle pain and cramps, abdominal pain, difficulty in walking and fever, among other symptoms.
