Extreme Home Insect Control Concentrate 16 Ounces | Kills 47+ Listed Insects On Contact Including Cockroaches, Ants, Houseflies and More, Use Indoors & Outdoors, Makes 2 Gallons

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!

It works immediately.

This mixed well into a sprayer. It works, but it sure is slow to send bugs to the afterlife.Had one large roach outside, and it took a few hours before I found the critter sunbathing on his back.Does not seem to smell when applied.

Save $$$ by DIY.Same ingredient as “professional” exterminators.

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. Kills annoying fleas fast

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.

Works great. Been using this for years
