Ratings & Reviews for BLACK FLAG EXTREME Home Insect Control 16 -fl oz Concentrate Insect killer

Doesn’t work

This really didn’t work. In fact, I think the ants laughed. It seemed to have brought more ants.

Keeps roaches at bay

I have used this product now for 5 years. I spray the outside foundation all around the house, the garage door, and the front door entrance. I can say I've never had a roach in my house all this time. As a bonus, Ive saved hundred of dollars on commercial pest control services.

Does not work

This product did not work sprayed it everywhere around the house did not kill a single roach even when sprayed directly on the roach. 10/10 would not recommend

Great!!!

Ive had lady bugs get into my home during the cooler months here in Tennessee, so last week I decided to go ahead and apply this product. I checked my crawl space, and the outside of my house, seen a lot of the lady bugs on the ground that were dead. I will be using this product from here on out before winter sets in.

Great on bugs...scorpions, too

I used this Black Flag bug killer, mainly to get rid of the scorpions but, of course it worked great on other crawlers also. I used it outside and I will continue using it.

Spiders

I hate spiders and this took care of them. Will continue to spray as needed.

won't kill roaches

had roaches invade my home when a friend brought a crock pot in with roaches in it (no longer a friend) and they scattered when the crock pot was lifted. I have tried several insecticides, and seen the concentrate at Lowes. Bought it and mixed it 2x the required amount. Caught a roach under a glass and sprayed the roach directly enough to cover the surface and glass. It says kills on contact, not true. Four hours later the roach was still alive. I had to squash it. Who can I trust to kill ...

I had high hopes for this product based on reviews. After multiple applications to the foundation of my home, I still see lots of ants. See photo.

Does not kill fleas

I purchased one ready-mixed and one dilutable (16 oz) bottle very recently for killing particularly fleas inside my house. I practically soaked the floors (tile and laminate flloring) with it. It does not work at all. I will request for a refund. I see one other person had the same experience with me. I have ordered something else as it does not helped me. So, don't waste your money and contaminate your house if you are using it for fleas. I can not say the effectiveness of the product for other...

Love it

This is the best store brand pesticide. We’ve literally tried everything. And the stuff works like a dream

Hands Down The Best

I’ve been using Black Flag for several years now and would give it 10 stars if I could. With the high cost of a monthly exterminator bill I decided several years ago to try the do it yourself option. I first went with the top selling brand but it was just so-so. The next stuff was even worse. Next my eyes caught the bright yellow Black Flag container. It worked great from day one! I spray my window frames, foundation vents and any other openings once every 2 weeks and have fewer bugs than I did ...

Seems to be working after spraying last night. My only issue is the outer packaging says nothing about fleas. Once you open and unfold the back flap, it lists them clear as day. Took me longer to assure I had the right product than it did to spray.
