Black Flag Extreme Home Insect Control Concentrate 16 Ounces

I bought this bug poison, mixed 2 ounces into a 32 oz sprayer, and sprayed it around home corners where spider webs form & around entry areas into home. As soon as I sprayed into spider webs, the spiders panic and flee the area as soon as possible but die seconds later. My home is bug free thanks to this product. Even after poison dries on surfaces it leaves a fill that still kills insects if the walk on it. Even ants are absent now at my house by spraying a barrier around house. Great product and affordable.

It works well indoors but for outdoors, it doesn't seem to work on concrete driveway. I'm trying to get rid of flea problems, it works spraying indoors and got rid of most of the bugs. Watch out when you stray it, if it gets on your skin accidentally by wind, it stinks your skin terribly for 2 days. You can't get rid of the spray by rinsing it or irrigating it with water or soap. It drives you nuts not being able to sleep because of the stink and itchiness. Hydrocortisone or anti-itch cream won't stop the stinking. It should have a warning to wear gloves and protective gear when using it. But the infestation is from the outside when I got out of my car in the driveway, the fleas instantly popped on my legs within one second. So I spray the outside yard around my house and the driveway. But the fleas kept popping on my legs after multiple spraying. Maybe it only works on dirt and plants but not concrete. Or the concrete needs to be soaked with the spray (which I have not tried yet), I don't know if it needs to be that drastic to get rid of the fleas on the driveway. I also use organic DE (diatomaceous earth) which usually worked in the past but for some reason, it doesn't work this season.

It works effectively; just make sure to wear a mask and sturdy gloves before mixing and applying it. Let's all finally get rid of these water bugs—good luck!

saw carpenter ants where a tree went down in the storm. i used this to reduce the possibility of infestation elsewhere.

I live in farm country and get inundated with Asian Lady beetles trying to get inside my house every fall. This product only sorta worked. Some dead the next day but many not. I mixed half bottle with one gallon and then the other half with 3/4 gallon. Sprayed ouside home multiple times. No improvement in effectiveness with increased strength. Will not purchase again.

I had originally given this only one start, since I could see a few dead bugs, but there were a lot more that were not at all affected. Then I realized you need to make more than one application, and apply it "EVERYWHERE!" When using it in just the corners etc., the bugs just move to somewhere that it has not been applied. I've had success in the past with the roach paste, where the application lasted a year or longer, but this time it did little, and I have more than just roaches, there are also ants and others in the mix. When this stuff is applied repeatedly and not just in the nooks and crannies, it works quite well. If you spray it on the counter tops, even walls etc. last thing at night, and apply it for several days in a row, it's surprising the difference that is seen. It's obvious to me now that more than one application is needed, and they will have to be done at least every few months or so, whenever the bugs start to come back, because they most assuredly will. The idea that you can just use it once and be done with them is totally ludicrous. It takes at least a few days of applications, which will need to be done again in a few months, if not a few weeks.

Living in an area where bugs are a constant battle, I needed something reliable for both inside and outside the house. This Black Flag Extreme Home Insect Control Concentrate has become my absolute go-to! The 16-ounce bottle makes a generous 2 gallons, which is fantastic value. I've used it around my foundation, on patio areas, and even for those rogue ants that try to sneak inside. It's incredibly effective – I noticed a significant drop in insect activity within a day or two of application. It tackles everything from ants and spiders to roaches and other general pests. It's easy to mix and apply with a sprayer, and the dual indoor/outdoor use is super convenient. While it's powerful, I appreciate that it's a concentrate, so I can mix what I need. If you're looking for a strong, effective, and versatile insect control solution for your home, this Black Flag concentrate is a must-have. It really helps keep the creepy crawlies at bay!
