Easily shots 3 feet or more **Q: Is this a dry spray. Does it leave residue?** A: It isn't a dry spray. It sprays wet and does cover a good area. When it dries, you aren't able to see it. It does dry fairly quickly! **Q: Can you spray this around doors so insects won't come inside? And does it really kill scorpions?** A: This is the only thing I have found that kills scorpions on contact. But you cant use it as a barrier to stop them. You have to spray it directly on the scorpion. The only thing that works as a barrier to kill scorpions is diatomaceous earth. **Q: How does it work on egg sacs?** A: I’ve sprayed and waited. Then whipped away egg sacs to dispose of. Works great. Sprays out far and fast. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Black flag works, it's as simple as that. *by T***L on 6 June 2026* There are several spider seasons of the year when they invade our homes looking for safe places to hide from rain or heat.

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. ## Frequently Bought Together - Black Flag Spider and Scorpion Killer, Aerosol, 16-oz - Hot Shot Ant, Roach & Spider Killer, Kills Insects Indoors and Outdoors, Kills Roaches and Listed Ants on Contact, Insecticide Spray, 17.5 Ounce (Crisp Linen) - Ortho Home Defense Max Indoor Insect Barrier with Extended Reach Comfort Wand, Kills Ants, Roaches, Spiders, Fleas and Ticks, 1 gal. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/733006831-black-flag-spider-and-scorpion-killer-aerosol-16-oz](https://www.desertcart.co.za/products/733006831-black-flag-spider-and-scorpion-killer-aerosol-16-oz) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-05*
