Review: Exceeded my expectations! - I cannot say enough good about this product. I have had flea problems in the past and I know what a task it is and how to get rid of them. It is no easy chore. One of the most difficult parts, is finding a product that actually works. I know how to prep before spraying or fogging. It is essential that you vacuum and vacuum well and pull furniture out from walls before you bomb or use any type of flea product. So of course I did that. I truly had an infestation at this point in time. You couldn't be in the room for more than a minute and they were crawling all over your legs. It was awful at night during the day all the time it was just getting worse. It got out of control in less than a week. So I have ordered exterminators to come to the house in the past. And they have had to come back multiple times to get rid of the flea problem. It's just one of those issues that you know it's going to be a while to get rid of. At least in my experience. I did my research and I believe Precor Foggers are one of the best Foggers on the market. But there again you'll probably have to use the product after 2 weeks of using the product the first time. But I am not for sure on this as it is my first time that I have purchased procore Foggers. While waiting for the Foggers to get to the house with a 3-day delivery I became impatient and noticed that I could buy the product bed bug and flea control and have it delivered the same day. To boot it was only 20 bucks. What could I have to lose. At least I could spray the damn bed and carpet and maybe get one night of sleep without getting attacked by bed bugs. That was all that I expected out of this cheap product or so I thought. I truly cannot say enough good things about this product. As I said I am currently waiting for my father's to arrive which will be tomorrow. At this point I honestly don't even know if I need them. I can't even believe that I am saying that right now. I bought one gallon and I addressed two of the rooms that were most significant with the flea infestation. I vacuumed very well pulled everything out from the walls and began spraying. I am telling you that within 2 hours I did not feel a thing crawling or see anything jumping around. I do not even believe my own words right now. I have adequate adequately sprayed both rooms with one gallon and even had a chance to do the hallways in the house that I was walking to and from those rooms. Just to make certain. I cannot find one damn flea in this house. I am simply amazed and flabbergasted that this product has single-handedly combated my infestation of two rooms with only one gallon and even had left over to do area rugs in the hallways. There is not one bug living in this house. There is not one bug on my dog. There is not one bug in my bed. I slept like a baby last night without any interference for the first time in weeks. I was able to walk around my room this morning and not a single flea had jumped on me not one nor have I been able to find one anywhere in this house. I simply have to say this product is an absolute winner and a must buy. I have stubborn fleas I always do when I get an infestation it was due to negligence of my roommate who forgot to put flea spray on his cats for 2 months and brought fleas into the house and it quickly developed into an infestation Within those two months then it was attacking my dog who I give advantage to and never has fleas my dog began to get infested even while taking the advantage monthly application and I've had to give him two or three flea baths a week to keep up so when I tell you it was an infestation I do not make light of the situation. I have had them before in my life and know how difficult it is to get rid of. I I'm not sure if I will have to reapply in 2 weeks but at this point I couldn't be happier. I did buy another gallon just to make sure I have it on hand at all times for 20 bucks who would be stupid enough not to buy this A1 product. Don't waste your money with any other more expensive or powders or other products this was the easiest thing I've ever done in my life. It couldn't have been more effective and the price you can't beat do yourself a favor save yourself the headaches get the same day delivery like I did and put your troubles to rest you will not be disappointed this stuff is fantastic my hat's off to ortho for a fine product better than the exterminators I've had in the past by far I just don't understand how this product has surpassed all others that I've used in all other services that I've used hands down the best.
Review: Huge effect in less than 24 hours - Woke up a few days ago to about a dozen bed bugs in the bed and blanket - about 10 tiny ones and a few adults. This was after seeing only a few bugs occasionally for weeks on the wall and mattress and not thinking much of it because we keep our windows open at night and had never had bed bugs before. Fin. Couldn’t believe it. Immediately went to desertcart and bought this pump sprayer, spot spray, powder, traps, interceptor cups for the legs of the bed, talcum powder, a bed bug-proof mattress encasement, and smooth contractor plastic sheeting. Still waiting on most of the stuff but the spray alone did wonders - hit the bedrooms base boards, window sills, and under the frame with pump sprayer. Installed interceptor cups on bed legs with talcum powder in the gutter area. Laid down plastic sheeting over the frame, overhanging by about 4 inches on all sides (we don’t have a headboard) and dusted the underside of the overhung plastic with talcum powder. Finally put the Hospitology encasement over the mattress and put it back in the bed with no sheets so we could observe (it’s a white cover). Nuked the pillows, pillow cases, and blanket in the dryer on high heat for 60 minutes. Had insomnia all night worrying about the buggers. The next morning - ZERO bugs in the bed. Saw some on the wall but they looked decrepit. Saw some in the carpet right next to the bed that were dying. And had some in the interceptor cups. Gonna spray the whole apartment tomorrow and distribute the powder and traps also when they arrive. Update: took a 5-hour nap in the afternoon because we were exhausted from prepping and no sleep. Still no bugs and now we can’t even find any anywhere. So far, this spray is a solid 5 stars but I will most definitely update this if that changes

### ⭐⭐⭐⭐⭐ Thank you, Ortho
*by M***Y on December 28, 2025*

If you are vigilant, thorough, and determined, with patience and proper use this stuff will save your home and your sanity. Bed Bugs are no joke and this particular Ortho option will destroy them but it takes time. You have to be very careful and persistent. If you catch the invasion before it's too late, this will save you but it will take more than one treatment to vanquish the pests. The sprayer is easy to use and batteries are included. The price floats around $20 and I promise it is worth every penny. I still have PTSD from the bed bugs but this Ortho spray made it so I could reclaim my home, life, ability to sleep, etc. This is also incredibly effective at flea control. If I had known about that I would have been buying this years ago. I hope that I never need this for bed bugs again, but I will never forget it and will definitely keep it in mind for flea control. The fleas don't take over but they tend to show up over the summer and I only saw maybe 3 fleas this past summer when I had to spray this for bed bugs. I love you, Ortho, this stuff is the best.
