Black Flag Spider and Scorpion Killer, Aerosol, 16-oz

It really works. I had a spider (not hairy) the size of a tarantula in the garage. It's no longer there.

I rented a condo with a semi-finished basement. It was spider heaven down there and I had hoped to make an exercise space in the basement. Every window space and ceiling joist was filled with spiders. I masked up and sprayed 1.5 of these cans around all the windows, inside and out, ceiling joists and nooks and crannies. I waited two weeks and then vacuumed up the webs. It's been two months and no spiders have returned. I had tried a different brand before purchasing the Black Flag and didn't have good results. So far I'm completely happy with the Black Flag solution.

Bought this to kill spiders inside & outside the home because we have so many. Since I started spraying this around the areas where they're most likely to crawl into i haven't seen many as we normally would! Love this stuff & I plan to buy more of it!

- 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

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.

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.

My girlfriend gets crazy with this stuff. Too many black widows' spiders love to hide in the BBQs and outdoor furniture. This stuff keeps them at bay. I let her have at with the spray. Really works well.

I bought two cans to take care of a spider outbreak around the roof of our home. Use them both last night, and yes, they definitely killed the spiders, but though the can says it kills up to 5', my experience with both cans was that it was very "misty" and the spray pattern was far wider than you would expect for on-contact spraying, thus I felt a lot was wasted and the two cans were quickly empty.
