Most spiders are harmless and just feed on other insects. However, there are two spiders that are considered dangerous to humans: Black Widows and Brown Recluses.
Here we will discuss these two spiders as well as House Spiders and Wolf spiders!
The name sounds ominous because it is thought that Black Widow females will eat the male after mating, but this only rarely happens. Black Widows have round, spherical bodies that are black with a red, hourglass shape on it. Young Black Widows are mostly orange and white and grow darker with maturity. They are most commonly found in sheltered areas like under rocks, in wood piles, under decks, in rodent holes, and occasionally in dense foliage. If found indoors, they are usually seen in cluttered garages and basements.
Named for its size and color, the Brown Recluse grows only to be about 1/4-1/2 an inch with a tan to dark brown body, with a darker mark on its neck. They feed on small, live insects and are found under rocks, boxes, woodpiles, etc. If inside, they are usually dwelling in secluded areas among boxes, papers, clothing, and crevices.
House Spider (Southern house)
While the house spider is not dangerous, they are nuisances because of their webs, and are usually found indoors. They vary in color from off white, to yellow brown, to black, with stripes. Their webs are mostly found in humid, secluded and inactive areas of the home like garages, barns, upper corners, and under furniture. Their webs can easily be removed with vacuums.
The Wolf spider may be scary looking and sounding – they are big and hairy – but they cause no real threat to humans. They are dark brown with grey marks. Unlike most other spider species, the Wolf spider actually hunts and chases their prey, usually at night. They dwell in sheltered areas like burrows, wood piles, decks, etc. They might get in to your property while chasing prey, and might not be eager to leave once they’re inside. Glueboards placed along walls, furniture, and doorways helps get rid of Wolf spiders.
