Review: It really works, seriously! - This actually works to eliminate fleas! I had tried everything prior to buying this product & nothing seemed to even put a dent in the sudden flea issue on my patio. These fleas were literally living in the cracks of the brick floor on my front porch. I don’t have an animal that would be the cause of this, so idk where this flea population suddenly came from. It was brutal, every time I was out on the porch, I was being bit on my feet & ankles. Fleas were jumping into my fuzzy slippers & I even brought 2 inside my house by accident. Over the course of a week, I tried covering the entirety of the porch with borax, which I did 2 days in a row. I then tried an essential oil based insecticide that claimed to kill fleas (it didn’t) which I used 2 days in a row. Then for the next 2 days, I covered every floor brick & the walls on the porch, with home defense. Which usually will easily kill every type of bug. All this to no avail, after 7 days & 6 separate treatments, I walked outside & had 4 fleas on my foot within a minute. So I researched & learned they can live & breed in the dirt or grime buildup between patio bricks. My porch is pretty regularly cleaned, so I didn’t think it was built up enough to foster flea eggs. Regardless, I spent 4 hrs blasting every speck of dirt out of in between the bricks, plus the walls were sprayed down. After it dried, I saturated the entire porch once again, but now with this flea & tick spray. It does have kind of a strong smell as you spray it, make sure to wear gloves & maybe a mask. The like tube between sprayer & bottle is like an inch long, so you have to carry the jug in one hand & spray with the other. Even trying to keep my distance, I must’ve breathed the overspray in my nose a bit, cause it really irritated my sinuses & caused a sneezing fit. The smell was present for a few hours after, but it wasn’t bad. After all that effort.. I was so happy, it actually worked! Between the intense cleaning & applying this spray, to every crack, every brick surface & the perimeter of the porch. I almost couldn’t even believe it. No more fleas in the last few days since using this product! I do anticipate spraying again though, probably within a week, just in case there’s any eggs still in the cracks. At the same time I ordered this spray, I also ordered these little traps that have a sticky glue sheet & a heat light above them to attract the fleas. I put those out at night, on the same day that I sprayed this, as those sticky sheets would show if there were still any living on the porch, even if not jumping on me. Luckily, I have not found any fleas in the sticky trap, just mosquitoes. Hooray for this spray! Don’t waste your time with any other products, just use this first! I wish I would’ve, it would have saved me from a dozen itchy flea bites on my ankles.
Review: Tried the Rest...this IS the BEST!!!☝ - EXCELLENT product!! We were quite SHOCKED when our "Indoor-ONLY" Kitty became infested w/ fleas! (😨YIKES!) We can only suspect that the fleas somehow entered our cozy, flea-FREE environment either by hitching a ride on the shoes/clothing of a recent visitor to our home who has pets, came in one of the many boxes or pkg deliveries we frequently receive, or one of our family members allowed a tag-along in, as they trekked thru our VERY "pet friendly" neighborhood. (That's just a 'Heads-Up' to anyone wanting to be vigilant.) At 1st we were in FULL denial when Jasmine (our kitty😻) 1st started "scratching" herself, thinking it must just be a mild case of dermatitis, or "something." Because after all, she NEVER leaves the house, so it CAN'T be fleas!! Oh, boy...how WRONG were we!!! (Consider that another 'Heads-Up!' I would suggest to just CHECK your fur baby at the VERY 1st sign of scratching/itching. DON'T make our mistake!!😰) I then noticed her scratching becoming incessant. Even to the point where she would wake from a deep sleep to SCRATCH! She even looked miserable. By the time I realized what it could possibly be, my POOR baby was infested w/ fleas!!😣 After FRANTICALLY scouring nearly EVERY website @ the internet & learning EVERYTHING there is to KNOW about FLEAS...I was ready for the "BATTLE!!!" (That's the term I hear/read ppl use all the time regarding their experience(s) with fleas. Because trust me...it IS just THAT: a full-blown "BATTLE!"😡 Lol) What I initially thought was harmless cat "dandruff" turned out to be flea EGGS! And my kitty had been shedding them everywhere in the house! (😨Yikes, again! Because I do mean EVERYWHERE!!) I headed to desertcart & LOADED my cart w/ EVERYthing & ANYthing that I thought I would need to fight this scourge of fleas! Flea & Tick: □ Shampoo, check; □ Tablets, check; □ Drops, check; □ Collar, check; □ New Vacuum Cleaner (You betcha, that's how determined I was to "WIN" this Battle! Lol) check; □ Wipes, check; □ Flea & Tick combs, check; and lastly the most important ingredient in the Recipe to kill those pesky PESTS... □ Spray!!! But, Holy Smokes...WHICH ONE?! Sooo many choices, sooo many price points!!😫 Where do I even begin?!😲 So I bought a WHOLE bunch of DIFFERENT ones: #1) Adam's: worked somewhat ok, but the smell & scent overwhelmed us, & our kitty HATED it! For the price, I thought, there could be better. #2) Hartz: GR8 price, worked relatively well. Good choice if you're needing to be extra price-conscious & need something that works. #3) Ortho (Aerosol): a bit pricey for such a small can, but does a GR8 job for hitting "hot spots" & dishing out an "instant kill!" Must use sparingly or, it'll all be gone B4 you know it! #4) Ortho (Liquid-Gal): Pretty decent job, no better or worse than the others. Didn't see any significant difference from others. #5) Black Flag Extreme Flea Killer (THIS Guy): I saved the BEST for last, because this puppy DOES the job BEST!! It incorporates the MUST-HAVE "IGR" component that helps win the "Battle" over those tiny monsters & their different "Life Stages," & you definitely NEED to catch them ALL in ALL of their various stages; adults, eggs, larvae, pupae, it has a clean scent that everyone in the house could live with, Jasmine didn't scamper off frantically at the 1st wiff of it (like she did w/ Adam's!) - in fact, she followed right behind me whilst I was spraying around the house, curious to see what I was doing - is priced quite fairly for its size (altho I noticed it went up a couple dollars from my 1st purchase to my 2nd; $11.XX to $13.XX - but that's ok👌 w/ me because it DOES WORK!👍, and it UNdoubtedly, absolutely knocked-DOWN the flea population in our humble abode, like nobody's business!!! The difference between all the other sprays & THIS guy was UNmistakable!! We noticed results almost immediately!! I can highly recommend THIS product WITHOUT ANY HESITATION!!! Needless to say...$200-$300 later I had EVERY hope that I could WIN this particular "Battle!" (Lol...I HATE losing @ ANYthing!) Knock on wood, we're about 99.9% there. (After nearly 3-4 mos of this Fight! And I'm tuckered out!😴+🤕) Yeah, I'm finding fleas...BUT, they're all DEAD fleas! (The BEST kind!😂) If you're also in the midst of a "Battle," or just beginning it, your approach has GOT to be MULTI-PRONGED!!! You CANNOT JUST give your fur baby a flea bath, or JUST put a few drops between their shoulder blades, or JUST buy them a flea collar & hope the problem goes away. (Because it WON'T!!) You MUST treat EVERYthing & EVERYwhere your 4-legged beloved one comes in contact with; Beds, Scratching Posts, Chew Toys, Favorite Blankey, etc., along w/ treating him/her. Then vacuum, Vacuum, VACUUM...like there's no tomorrow! Be VERY vigilant w/ baths, drops, buy a decent flea collar, spray liberally, etc. & watch for ANY possible ways fleas can infiltrate your home...And hopefully YOU, too, can WIN your BATTLE against those MUCH hated fleas & ticks!!! Good Luck!!! I hope my long-winded (sorry 'bout that! I had to "share" as much as I could to help YOU, the SAME way others helped ME!) dissertation proves to be of some small measure of help. Fleas & Ticks SUCK BIG TIME!!! WHO NEEDS 'EM?!!!😬 P.S. Just a ☡Cautionary Note - since I already did the Homework: Do NOT treat your pet w/ more than one treatment at a time!!! You do NOT want to overwhelm or shock their system & have them get sick. Please space your treatments, or consult your Vet for further advice. If you can't afford a Vet, check out the website: Flea Science. Terrific info & insight. (No...I'm NOT affiliated whatsoever. Just found it packed w/ exceptional knowledge.) P.P.S. If my Battle starts to falter & the remaining .01% needs to be conquered w/ something else, I've been advised that a WHOLE house "Fogging" might just do the trick! You may want to consider incorporating that in YOUR Battle. Good Luck, again! & Have a GR8 Day!!!😊

## Questions & Answers

**Q: Why is there a lot of "vine customer review of free product ?" they all have a 4 to 5 star review while the ones who really bought had 1star reviews.**
A: They get paid to give good reviews of products, thats why becky got so butthurt and figured calling you “chad” was enough of an insult for pointing out their lack of integrity because of their disingenuous gig job giving disingenuous reviews.

**Q: Can some one answer please?can i used this products with my cats and my dog in my house or have to take them to the other place?this is toxic for them**
A: I have both cats & dogs...just keep them off of the area until it's "completely dry"...then it's all good after that.

**Q: is it safe to spray on mattress?**
A: I've sprayed it on the sides of my mattress didn't have any problems with it.

**Q: How long does it take to kill a flea? I've trapped some live fleas in a plastic bag and sprayed them. That was 7 hours ago and they are still alive.**
A: I was a little disappointed in its killing power myself. As itself being a black flag product I thought it should do a better job.
