Black Flag Extreme Home Insect Control Concentrate, 16 Ounce, for Indoor and Outdoor Use, 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 is perfect and it's right on time just what I ordered and needed in great condition

Good value for the money.

This solution kills just about every bug you can think of. Mixing it up in a spray bottle with water, according to spec ratio, makes a lot of solution that last a while! Doesn’t take much and works very well. However, Does not work on ants. Just spray outside the perimeter of your house and it takes care of insect issues for months on end.

This concentrate (must be diluted) is one of the newer, greener pyrethroid insecticides, deltamethrin, that's trying to replace organophosphate and neonicotinoid insecticides. It's a low potency, no odor insecticide designed primarily for _indoor_ use. You should NOT use it on eatables because it has a 12-month lifetime. There are better insecticides for outdoor use.For vegetables, I use Bug-be-Gone, which contains neonicotinoids. Avoid spraying flowers, which would hurt bees.

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.

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

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.
