The picture is out of focus thus hard to tell exactly what it is; however, it looks like a wolf spider. All spiders are venomous. All spiders are capable of biting; however, spiders almost never bite. Spiders are often accused of biting but it rarely occurs. If a person were to be bitten by a wolf spider the reaction would most likely be similar to a bee sting and precautions should be taken accordingly. Meaning, if someone is allergic to bee stings/arthropod venom, they may be allergic to spider bites. Only two spiders are known to cause serious health effects on people (beside possible allergic reactions). Brown recluses (no known breeding populations in SE PA or in DE) are not native to our area and are rarely encountered. Recluses are usually encountered when someone has traveled from their native range to here or had something shipped. Black widows are common to our area and also have a venomous bite. They tend to stay in out of the way places much like the brown recluse though; thus they are rarely encountered. The pictures provided are NOT brown recluse or black widow. Management would be as simple as capturing with a jar or container of some sort and relocating the spider to the outdoors. Spiders (all) are beneficial arthropods that feed on a variety of other arthropods which sometimes include garden, flower, or tree pests.
