I have not written a review for this product and it works great. My first dealing with bed bugs were decades ago, when I realized that song, "don't let the bedbugs bite" Were actually true BED BUGS the demon of all bugs. When I first got them you had to tent your house because there was NO WAY to get rid of these little beast that only keep reproducing themselves and anyone that comes to a bedbug home will get them. Thousand of dollars. Speeding it up to today. Bed bugs said we're back! THIS PRODUCT WORKS BUT LISTEN UP. You have to spray every two weeks for a month to a month in a half. Because it doesn't kill eggs. So the first spray will kill that little beast that's sucking your blood when you sleep but not the eggs they left. So you spray wash bedding NO MORE BITES. And a couple weeks later that little bump appears on your legs and arms AHH it didn't work! Yes it did but you have to respray, kill the hatched eggs wash blankets again. Mark your calendar for the next spray. I've gotten all these bedbug sprays an costly too. But this works and what's amazing is the size. It actually gives you enough to repeat the spray. Hopefully the bug beast didn't travel to other parts of the house. If it did get a couple of these bottles. Spray the carpet. This works and better than the expensive little bottle for a 100. Thank you YAY Read more

Works good.

Amanda hallMarch 7, 2026✓ Verified purchase

Works good if used often and correctly. Spray once a week along with vacuuming daily and wasing bedding and pillows frequently. A mattress protector is a must as not designed for it for sleep areas. Used for cat fleas and ants Read more

Fleas, Fleas everywhere with lots of blood to drink

VampyraDecember 21, 2023✓ Verified purchase

I have several cats, and I didn't know we had fleas. My Shark vacuum broke, and while I waited for parts to come, my house became infested. My cats were acting crazy by sleeping in my top loader washer, shower, and kitchen table. It was so bad that fleas were crawling all over me and even got into my bed. I didn't know why I had an itchy rash on my legs and why my legs were starting to swell. I took a flea comb and ran it through one of my cats, and it had tons of fleas crawling on the comb. We had a major infestation. I was mortified! From what I've read, if you have a problem this bad, you will need an exterminator. That was not an option for me. I just couldn't afford that kind of expense. I had to find a way I could do something that wouldn't kill my cats. You will need a powerful vacuum before you start. Preferably something with a HEPA filter. You will need to vacuum "at least 3 times as long as you normally would" before you start, and move all your furniture. I sprayed it on my couch and under my couch cushions. The vibration of the vacuuming makes the larvae hatch, so be prepared. You may need to spray (at least the carpet) every 2 weeks with Ortho because they will keep hatching. I suggest getting 2 bottles of Ortho to start if your problem is this bad. I am already on my 4th bottle, but the fleas are almost gone. Vacuum the hard floors too. Vacuum as often as you have time for, and for longer than you normally would. Shake the bottle well before each time you spray. Ortho has a pleasant smell. When I would come home from work, I was shocked at how nice my house smelled. There was no nasty chemical smell to this stuff. After the first spray, things got way under control, and I wasn't loaded with bites anymore. I bought this and Tekko Pro IGR, which is an insect birth control with a cheap hand-pump garden sprayer. I made a gallon of Tekko Pro in the garden sprayer and locked up my cats. I vacuumed the whole house and scrubbed all the hard floors first with pine cleaner. Dump your vacuum outside and never leave dirt in your vacuum. As I cleaned sections of the house, I sprayed both the Tekko Pro and the Ortho on the whole carpet and hard floors. I took my foot and rubbed it into the carpet and made sure it was damp. I have several box fans and turbo fans, and I blew them on the floor to dry it. I have ceiling fans and I turned them on too. You want this stuff to dry. I even sprayed the sides of my mattress and box spring like you would for bed bugs. You can open or crack your windows open while it dries. I bought Nitenpyram powder and capsules (generic Capstar) and learned how much I should put in a capsule. That pill is given daily. I also bought Lufenuron capsules and powder, and learned how much should go in a #4 capsule for cats. I mark on the calendar when I give the Lufenuron because that one is given monthly. If you do these things, you will really get your problem under control. There is way less scratching and chewing going on with my cats. I keep combing them looking for fleas. It's rare that I even find one flea. The comb is not for removing fleas. It's for checking for fleas and flea dirt. You can NOT use a flea comb and think this will eliminate your problem. You'll be in a heap of trouble if you don't listen to me. I hope if you have fleas, you listen to what I've told you, and you can get your problem under control. Make sure you wet down your whole carpet and behind things like dressers and bookcases that you can't move. You can't miss any of the carpet or floors. In open spaces, rub it into the carpet with your shoe. Make sure it's dry before you let your cats back in. If you do it in sections, it will dry much faster. I even sprayed it on pet beds after vacuuming or washing them. Just make sure they are completely dry before you give them back. You can spray down pet bedding every 2 weeks. You can throw the pet beds in the dryer weekly for 30 minutes, too. That makes a big difference. I sprayed my house with the 1st wand with each new bottle. So if you buy more like I did, save them all in case one won't spray. If you have any left from the first bottle, add it to your new bottles. Don't waste anything. Read more
