Are black widow spiders dangerous?

Female black widow spiders are much more likely to bite than a male black widow. This is especially true after they have laid eggs. The male’s poison/venom sacs cease development and he does not attack prey upon maturity. It’s interesting to note that spiderlings are poisonous when ingested until they are 18 days old and then lose their toxicity. A black widow spider bite can cause nausea, sweating, increase in blood pressure, as well as fever. The first few hours of a black widow bite are the most painful with the pain getting worst around 3 hours. The pain can last for several days but gradually lessens over time. Black widow spider bites are rarely fatal if proper medical treatment is received. 

Black widow spider habitat.

Like most spiders, black widows are most active in warmer temperatures. They prefer 70 degrees or higher. Black widow spider webs are typically less than a foot across and usually low to the ground. Like Spider-Man they prefer to hang upside down while they wait to pounce on insects snagged in their web. 

Black widows like dark, dry areas to spin their webs in. They can be found outdoors in barns, outbuildings, wood piles, under decks and porches, inside meter boxes, rodent bait stations. You may find black widows in dark areas of garages, crawlspaces, basements, and cellars. 

During the winter black widows will move indoors for warmth and shelter.
