Probably it’s very dangerous
If the spider in question is really a black wolf spider, beware! They’re fast and it can be difficult to catch them. In general, wolves are not only one of the largest types of spiders in North America; they’re also among the general’s most intelligent ones. Fortunately for us, most people would never spot one because they prefer to hunt at night or hide high up on tall surfaces like walls and ceilings above human activities.
The good news is that many spiders are actually harmless and can even help combat pests outside through its pest-killing webs.
