## Description

Insects invading your corner of the world? Whatever insect you're fighting, Black Flag® products are dedicated to providing the tools you need to regain control. With formulas that act fast and never back down, Black Flag insect controls have been arming homeowners in the battle against invading bugs for more years than any other brand. Black Flag extreme home insect control Concentrate makes 2 gallons of spray for use both indoors and outdoors to control listed insects on contact. Perfect for tank sprayers! Effective on 47 listed insect pests, including roaches, ants (including carpenter ants), spiders, centipedes, fleas, ticks, mosquitoes, flies, scorpions, moths, beetles and bed bugs. Kills German cockroaches for up to 9 months on non-porous surfaces. Perfect for use in kitchens, bathrooms, basements, attics and other household storage areas. Also works outdoors in areas where insects live and hide, including the perimeter of foundations, doors and windows, window screens and frames, and porches, patios, decks and garages. Apply around the perimeter of the home both indoors and outdoors. Spray around the foundation, doors, cracks, crevices, baseboards, around plumbing and other utility installations, exterior windows and all any other points where insects may enter. Use for spot treatment, holding 12 inches from the insect or surface to be sprayed. Spray until slightly moist but not to the point of runoff. Use as a refill for Black Flag extreme home insect control. Apply at the rate of one gallon of finished solution per 1,000 square feet as directed by label, following all precautions and directions.

Review: The Terminator! - 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.
Review: Works well but the spray stinks your skin really bad for 2 days if the wind blows your way - 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.
