Fortunately, as naturalists, we realize spiders have great value in the ecosystem and when found indoors, we tend to reach for a container to escort them outside rather than immediately grab the insecticidal spray.
They are very easy to recognize, particularly the larger females with her shiny jet-black body and very long legs. To aid in identification, they have a signature red or orange hour glass symbol on their abdomen and tend to hang out upside down in their webs, warning others to not eat them – a warning heeded by most predators except for birds and preying mantis who relish them as a snack.
The female creates a light tan, round egg mass which contains up to 400 babies. The young tend to hatch at the same time so they will be about the same size, preventing older, bigger spiderlings from eating their smaller brothers and sisters.
Prevention is the best way to not get bitten – wear gloves and don’t stick your hand in places you can’t see or check first. If bitten by a black widow, seek medical attention immediately. Death is not likely but swelling at the bite site, severe muscle aches, dizziness, sweating, headache, anxiety and nausea may result.
As with most things, a healthy respect allows for acceptable cohabitation as long as the black widows stay outside in areas not frequented by humans, particularly kids and elders. If found indoors, the choice of whether to escort outside (very carefully with proper protection) or to spray is up to the individual. Fortunately, black widows do not jump.
