Ortho Home Defense MAX Ant, Roach & Spider Aerosol Spray

I bought Ortho Home Defense Max to use inside my home, and I was impressed by how fast it works. From the first application, it started killing ants, roaches, spiders, and even fleas. The sprayer is easy to use, and the product dries quickly without leaving a strong smell. I noticed a huge difference right away—bugs stopped appearing, and the protective barrier lasts for days. It’s effective, convenient, and the 1-gallon size goes a long way. I 100% recommend it if you want to keep your home insect-free quickly and safely.

Ignore the skeptics—this stuff absolutely works. My wife and I recently moved to Vero Beach, Florida, where cockroaches (politely called “palmetto bugs” here) are just a part of everyday life. Coming from Ohio, we were not prepared. These things are huge, fast, and while technically harmless, they’re still shocking to see crawling around your home. At one point, we were seeing multiple cockroaches inside every single day, and we knew we had to act fast. That’s when we found Ortho Home Defense Max, and it changed everything. We sprayed it around cracked and vulnerable areas—under the fridge, behind the stove, near baseboards, and along door thresholds. Since then? We’ve seen barely any. Maybe one or two stragglers in total, and that’s in a house that previously felt like a roach runway. To test how fast it actually works, we found one cockroach outside, trapped it under a glass bowl, and sprayed some of the product underneath. Within an hour, it was dead—completely flipped over on its back. That proved to us this isn’t just a long-term prevention spray—it’s a legitimate killer that starts working fast. What’s even better is that this spray doesn’t just kill on contact. It continues working over time. Roaches that encounter it can carry it back to their hiding places, infecting others and breaking the cycle at the source. Here’s our recommendation: ✔️ Spray it around common entry points and hidden crevices ✔️ Stay on top of cleanliness (no cardboard on floors, no food crumbs left behind, trash secured) ✔️ Let Ortho Home Defense Max do the rest If you’re new to Florida—or any place where cockroaches are common—and you’re horrified to find them in your home, this is the first product you should buy. And even if you’ve lived with them for years and think there’s no solution, try this. You’ll be amazed. Five stars. Hands down. Worth every penny—and a little bit entertaining, too.

I had a kitchen ant problem for months until I used this product. I tried all the home remedies and then two different brands of ant traps. None worked. I was reluctant to use a chemical spray (though I am a chemist) because I have a cat, but the label promised that this was safe around pets when used as directed. Despite the "indoor" label, I used it both indoors and along the house foundation outdoors. It worked. The ants are gone (and still gone six months later) and the cat is doing fine. What more can I say.

I have a horrible bug phobia. I use this extensively inside my home. It does pretty well at preventing bugs from being seen in the areas that I have sprayed. Also less bugs come in the windows after I spray around the window frame. It doesn't seem to leave an oily residue or any scent. Its not a good spray to immediately kill a bug though, they take a while to die.

It functions as advertised, to my surprise, and is a much better, quicker, longer-lasting, and less visible solution than the trap-based pesticides we had used against ants before. In fact, the applied effect was almost instantaneous since we knew the general entry point for the ants. Warning: this was applied in an area where pets are not expected to frequent, so please review the details and exercise good judgment if you own pets.

Ortho Home Defense does help reduce bugs—but if you live in a townhouse where units share walls, it’s an uphill battle. I used this consistently in my small place—spraying baseboards, around the kitchen sink, and other problem areas—but the bugs kept coming back. Unfortunately, when your neighbors have them too, they just migrate from one unit to the next. You can’t control what’s going on behind their walls. The area around my kitchen sink is the worst. I spray there, but every time you run the water, you rinse the product away. So that area needs frequent reapplications. I went through a full gallon in just a month—and I’m still seeing ants and roaches pop up. To be fair, the townhouse is pretty old (50+ years), and I suspect the infestation runs deep inside the walls and plumbing. At that point, no over-the-counter spray is going to be a permanent fix. I'm actually planning to move soon, because I don’t think this place is salvageable. If you live in a newer or more tightly sealed unit, this product might work better. It’s definitely helpful for spot-treating baseboards and doorways, and I’ve seen some improvement with consistent use. I also tried a few home remedies—like vinegar (bugs avoid the smell) and a sugar + baking soda mix (which is supposed to kill them). Those helped temporarily, especially when I ran out of spray. Bottom line: Ortho Home Defense is okay for managing bugs, but don’t expect miracles in older, shared-wall housing. Be ready to reapply often and consider other solutions too. Sometimes, the only real fix is a change of address.

Fantastic product. Sprayed whole house and have not had to re spray. The roaches were awful & the crickets horrible. I trust this product.

It came broken, and leaked a LOT. Thankfully I was able to fix the sprayer, and use what was left. It worked very well, very easy to use, and has been working very effectively. Loved this product.

I can not find the words to describe my utter disappointment with this product. It promises to get rid of cockroaches after one treatment and her I am after multiple applications and absolutely no evidence of any effect! It really feels like a scam. I am frustrated and disappointed that Amazon allow such scams on their website. I certainly would recommend this product.

not as effective and despite the wrapping, thr liquid still poured on the packahing
