Garden Chores Turn To Horror Movie
My wife sent my 10 year old, Gracie out to weed a little flower bed in our front yard, and she came in a moment later to tell us she had found a black widow and her egg sac in one of the pavers around the bed. I went out with some bug spray, and just to be sure, I turned over a paver to see if there were any more. I found one. Then I turned over another and another with the same result. Ended up with more than a dozen spiders and more than 20 egg sacs. I thoroughly saturated the area with permethrin and hope I have solved the problem.

Yep, that's a lot of spiders.
If you look hard enough, you will find spiders. I think the number of deaths from spider bites is low and remind you that driving a car is more dangerous. Since you seem to have done a thorough job of killing spiders, I suppose the other insects are happy. Wait I want to retract that and say that I suppose your family is safe now.
Reminds me of the movie Arachnidphobia... well, except that movie had an impossible amount of spiders in it.
@PPhilip - There are spider webs all over the outside of my house. I pointedly allow most spiders to live outside and assist us in the control of insects, even though I suffer with an irrational fear of the critters. Spider bites may not be a statistically high source of death or serious injury, but the statistical risk certainly increases with an infestation, and I would consider a black widow under almost every paver in a small area to be the beginnings of an infestation. One of my six children was bitten a couple years ago by a brown recluse and though it was not life threatening, it was serious enough to be extremely painful and require care at the hospital. Yes, fear of spiders may be as overblown as fear of sharks, but the danger of an untreated bite from a black widow is real and I hope my family is somewhat safer now that I have treated the area and killed all the spiders I could find.
So glad your daughter didn't get bitten -- I hope the spray kills the egg sacs as well as the adults!
Autumn will have the "normal" spiders come out and put out the normal webs. Black widow spiders have the irregular tangled looking web. The brown recluse has a violin shaped marking on their backs and a distinctive trio of eyes (very hard to see). Even though there is less than ten deaths per year for black widows the news has reported an increase in Black widow spiders.
Basically the larger spiders are female and it is the larger size and larger venom sacs that makes them dangerous. No known male black widow spider has been known to be a killer.
Strangely I don't know if pesticides kill spider egg sacs. The spider egg sacs are a bit water repellent. Good luck on your mission to make life safer.
we have a problem with black widows in our yard, as well. this definitely concerns me... especially since a couple of years ago i was weeding in the garden, looked down and one was right beside my hand... under A LEAF. no rocks nearby.
i was under the impression that there were no effective sprays for black widows. i would SURE be happy for that impression to be wrong. seen any results yet?
@ehrinn_l - The permethrin spray (permethrin is found in most flying insect sprays) worked well on the live spiders, but I was instructed to use a high potency permethrin spray like "Talstar" to kill the egg sacs. Another option someone had used was to use a small torch, but it would have to be in an area not prone to fire. I'll probably be buying the Talstar.
OMG that's bad Im glad your daughter knew not to touch them @@@
YIKES! I am glad we don't have those kind of spiders here! I hope you discouraged them PERMANENTLY!
Yikes, that is a tad scary. Good luck with you spider situation!
I wonder why they like the pavers, I usually find them just inside the garage doors and around the inside of the tack room door. I agree with the live and let live attitude unless they are in a spot where I could intrude on their space accidentally. I'm not so sure about poisoning your environment though; couldn't you just smash 'em?
@judyrutrider - The pavers were stacked and staggered with small spaces between them. Perfect place for a black widow as they (from what I've heard) like dark, out of the way places. Permethrin isn't as poisonous to humans as it is to insects and arachnids b/c humans can metabolize and eliminate it. It's the same insecticide used to kill lice in your hair. Only concern is it kills insects indiscriminately and doesn't wash away quickly, so if you're not careful and spray it on flowering plants you can kill the bees and butterflies and other beneficial insects.
I really wana thank you for providing such informative and qualitative material so often.
