Two black widows in one day


For decades, I went through life seeing just one black widow spider -- and it was alive but enclosed in a created habitat at the Smithsonian Institution. I know they are found in Delaware because a friend of mind had to call in an exterminator a few years ago when she discovered her then-8-month-old son crawling on the same patio as a black widow.

But frankly, I never gave it much thought that they would be in my yard. Then, the other day, I went to throw away a spoiled lemon and I opened our municipal trash can and noticed a spider in a tangled mess of web back in the corner. I got a little closer and noticed it was glossy black. And then I saw the long legs and I started thinking, 'Could it really be a black widow?'

So I got a little closer and thought I saw the hourglass thing-y. But I wasn't sure. So I went in and got a camera and took some pictures. I told my teenage daughter about it so she could be careful.

So here's Lesson 1: If you tell a teenager there's a black widow living in the trash can -- forget about getting any help taking the trash out.

Lesson 2: If you have one black widow, you just might have more. I'll explain. So later that day, we came back from Rehoboth Beach and my daughter went over to our Delaware Solid Waste Authority curbside recycling bin to toss a piece of cardboard.

She stops midway there, recoils and shouts: "Spider! Black widow!"

And sure enough there was another one, reclined on the outside of the recycling bin.

Because it looked like it was dead or dying, I picked up a twig and looked underneath and there was the hourglass.

I'm curious why it died. At first, I thought it might have been food for a bird. Old age? Are we facing lots of black widow babies in our future? Then, I thought maybe black widows have their own space and they don't tolerate competition.

Any thoughts?

Black widow spiders have been around Delaware for years. If you see one, chances are there are others because if you see the hourglass it is a female. The female is the dangerous sex, the male doesn't bite...Black widows tend to build their webs in a protected space (reason you seldom see them), and prefer some place warm. While a bite from a black widow can be serious, healthy adults rarely die from a bite. Do seek medical attention because the venom is much more potent than a rattlesnake.
Thanks for that comment. Great additional info! ... Justin
I knew that Black Widow spiders have existed in Delaware. I've lived in Delaware practically my entire life and have only seen one once. Which was a couple of years ago. However, I've noticed them popping up with more frequency. Just a couple weeks ago I was working in my back yard and took a cushion from one of my chairs outside. I folded it over and there she was with several egg sacs. She actually ran over to one of them as if she was protecting it. Then as I explored my backyard further I was moving a couple planters. Underneath the lip was one more. Then move another pot carefully, and yet another! I haven't seen any more since, but it makes me wonder. So for those of you who haven't seen one yet be careful as you get you backyards ready for a labor day picnic or preparing your garden for the fall.
i have a widow as a pet and i live in b.c Canada,and i found her on my door frame and i kept her ,i found another widow not long afte that,and droped her in with my pet black widow and my pet killed her right away ,so you are right about a widow not living with others .they like there own area, and females can lay 6 to 9 sacks of eggs off one matting with another male widow ,so the chances are you are going to keep seeing them they made it this far they aint going to stop until its to cold for them
I found a shiny black spider that was hiding in my sprinkler, it was sluggish, my husband killed it with Raid - it had an hour glass on the underside. The next day, cleaning up in the yard, my husband was cleaning out spider webs and another spider ran out and up under the siding. I'm not a spider fan, I would shoot them if I could, now I'm really concerned about black widow spiders under the siding of my home. My grandson spends time here, I'm concerned about him being bitten in his bed. How dangerous are these things? This is the first time I've seen black widows.
