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.

- Had good, directional spray. Was able to hit spider on the ceiling. - Didn't kill the spider instantaneously, however it seemed to paralyze it pretty quickly so it couldn't run away. Probably took 30 seconds to kill the spider. - Overall I would use this product again

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 😳

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.

Works fast on black widows. I normally don’t use chemicals when it comes to controlling insects but when it comes to black widows or any other toxic bug I do make an exception. I must make a note: I have never seen so many black widows and brown widows in the area that I have lived in in the last 30 years than I have in the last two years. I have no idea what is causing this influx but it’s extremely dangerous. I have had black widows that I’ve come inside my house, which is very well sealed, and I could hear them walk across a paper bag! They are absolutely gigantic! To the dismay of my sleeping husband I woke him up at 3 o’clock in the morning. He was very angry at me but when I finally got him to see how big that black widow was he freaked out! I have never seen my husband freak out over a black widow before over the 40 years we’ve been together. I could put a saddle on that spider and rode it into town! I tried many different kinds of non-toxic chemicals and toxic chemicals to kill black widows in their tracks and this is the only one that worked.
