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

Had an issue with spiders getting inside the house. This spray kills spiders pretty instantly. Would recommend.

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 😳

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.

This stuff does kill spiders. Black Widows, which are notoriously tough, struggle and fight for a minute or two - but eventually they die. My only problem with this product is that the stream is extremely aggressive. It comes out hard, tightly streamed, and in mass volume. For comparison, Hot Shot brand spider killer is the exact same active ingredients, and you get about 25% less volume with the Hot Shot, for about 25% less money. But the 11 oz. Hot Shot actually covers a lot more area, because it comes out in more of a fog, less of a stream.If you are gunning at a speeding spider or scorpion, then maybe you need the intense stream of the Black Flag. But, if you are treating an area, then I think the Hot Shot is the better option. Again, both products are the exact same active ingredients. If you like to mix up insect killers to prevent species resistance, know that the Terra brand uses different ingredients.I took off one star, because you really can't treat large areas cost effectively with a stream this aggressive. And for my needs, the Hot Shot "fog" is satisfactory for spot killing. If you are just picking off speedy pests on the spot, then this might be your best option. If you are primarily area treating or spot killing bugs of the non-speedy variety, then go with the Hot Shot or Terra.I can't offer any perspective on the effectiveness against scorpions,....only spiders.

This product really workswell and have only found online to purchase.

good product

My garage has an infestation of spiders. This spray helped alot. Thank you for it.

Will kill spiders but not instant most of the time. Leaves a greasy film behind.
