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

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.

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 used this..make almost a Gallon with Half the bottle..and they fall right on their back when I spray them directly...they don;t really run away like they do with the foggers Foggers are useless-they know it;s poison and they just run off to another room. Never set a fogger off in just one room. As for this,.. I will keep using it and see if they start to diminish in population. Don;t fill the gallon jug you might be using with as muchwater as it says to use. Fill it with about 3/4 of gallon. You want it as strong as possible when spraying.I bought a power sprayer wand..now I feel like The Orkin Man.

Does a great job eliminating spiders on outside house.

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.

Works great.

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 mixed according to the package directions and I may have well have been spraying water. I sprayed directly on spiders only to watch them happily go about their business 3 hours later. I captured some cockroaches in a container and dropped in a paper towel soaked with this product to absolutely no effect on the cockroaches. I bought this product because I can use it in a pump sprayer, I can't tolerate the fumes from spray cans. I hope this saves someone else the time and money.
