how spider venom work-
Let’s get this out of the way: That red bump is probably not a spider bite. Odds are, it’s a skin infection. The most common bacterial infections are either staphylococcus aureus or streptococcus. Both of those create red bumps that get hot, swollen, and spread out.

It walks across the thread, releasing a looser thread below the first one. It attaches this thread on both ends and climbs to its center. The looser strand sags downward, forming a V-shape. The spider lowers itself from this point, to form a Y-shape. This forms the core support structure of the web.
The spider easily grips the thin threads with special serrated claws, a smooth hook and a series of barbed hairs on the end of its legs. As it walks along the initial structural threads, it lays more frame threads between various anchor points. Then it starts laying out radius threads from the center of the web to the frames. The spider does not coat the frame and radius threads with sticky material, since it needs to walk across them to get around the web.

After building all the radius threads, the spider lays more nonstick silk to form an auxiliary spiral, extending from the center of the web to the outer edge of the web. The spider then spirals in on the web, laying out sticky thread and using the auxiliary spiral as a reference. The spider eats up the auxiliary spiral as it lays out the sticky spiral, resulting in a web with non-sticky radius threads, for getting around, and a sticky spiral for catching bugs.

if it is a spider bite and you got it in the United States, it’s very unlikely that you will die from it. Of all the spiders in North America, only two are medically significant (capable of actually making you sick): the black widow and the brown recluse.
Plenty of skin rashes and sores get diagnosed in the emergency department as spider bites, but the reality is that most are not. One case study of an outbreak of bites in military barracks—at least what authorities thought were bites—turned out to be MRSA.
