## 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: My Go-To for Bug Battles - 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!
Review: Very Disappointed with this at first, then when I learned more was happy with it - 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.

### ⭐⭐⭐⭐ Good but slow
*by J***J on June 29, 2024*

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.
