It did kill the spiders
I was having a spider problem, and i'm not anymore. I do have pets but anytime I use any type of bug spray, I put them in an area that i'm not spraying, and then spray clean up and then let them out. I had absolutely no problems with like a residual mess. It did what it was supposed to and my spider problem in those areas was no longer a problem. And I can say it did not affect the cats or the kids at all.

Spider
Just in time to get rid of my spiders. It was an excellent value for the money. The spray can top does not leak, so I feel safer that I will not get sprayed, which makes it safer. Well, I sprayed, and after half an hour, it was effective.

WORKS!
This works great on both scorpions & black widows. But it's become hard to find. Lowes doesn't carry it anymore. So glad AMAZON had it! ... When you have to get rid of a black widow (& her fam) you need something that does the job on the first try 😳

Kills Invasive JORO spiders
Finally something that kills the invasive Joro spiders, and you don't have to drown them for it to be effective. A one second spray is enough. One can killed about 47 spiders around the outside of our home. Hooray! I like this so much, I bought a case! (That should last us though the summer). Excellent product. Decent spray range. I only wish the stream could spray a little farther, like the wasp spray does. Only the first spritz goes 8ft. The rest of the can sprays more like 4-5ft distance.

Essential spider spray
Took care of my spider problem on my porch.

Yellow Jackets
Perfect for dealing with Yellow Jackets nesting in the ground or in the wall. This will at most shoot 5 feet, so you will have to get close.

Relief from spiders
I live in a place with a lot of big, fast, hairy spiders that like the indoors. I can’t take it. The can says it won’t hurt my cat and will last for weeks. I used to use the kind you’d spray outside around the foundation. It would last all summer. It’s too hard for me to spray outside now. I’ve sprayed twice indoors this season. No spiders. My cat is ok. That’s what I wanted. Very happy.
