Black FlagExtreme Home Insect Control Concentrate, 16 Ounce, for Indoor and Outdoor Use, Makes 2 Gallons

Great stuff! I use it to keep spiders off my boat and outdoor kitchen. Twice a year and you’ll never see one.

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.

Good value for the money.

I purchased this because we have had an ongoing flea issue for months now... and I have been going crazy trying to get the right thing to help. I've tried quite a lot of different products for in home treatment and if any of that helped, it never actually got rid of the fleas. Now FINALLY, I got this and it works!!! Impressively, might I add. I only mixed a small bottle size and there's plenty more product left but I treated our apartment in the places appropriate and instantly i notice the difference! I have not been bitten by even one flea since treating the home with this insecticide!! It's a fantastic prijĵ/ce! Great value! You get A LOT with a concentrate like this, I'm absolutely beyond thankful for this product !!!

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 have a serious ant problem during the summer months. I have tried other brands that just don't work. This poison works amazing. It keeps killing and killing day after day. It kills ants, roaches, and many other insects. I am HIGHLY impressed. I make my 1-gallon mix by following the directions on the bottle, but I add about one extra ounce of poison.

I stopped the pest control company because I was seeing large desert cockroaches outside of my home. I used this item and it did the trick. I was finding manu of the roaches dead on driveway and close to the front porch. Worked so good I will be purchasing again.

Sprayed this as directed around the outside of my house, and nothing happened. I even had some ants on the porch that i wanted to kill before they reached my humming bird feeder and sprayed it on the directly, and it did not kill them, even though it says "Kills on contact" on the front label. Completely worthless it seems. Do NOT buy.
