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.

This product is effective in keeping spiders at bay. It hasn’t a scent and works well both indoors and outside. For outdoor use I use it around the outside border of the home as well as inside including window seals and along each exit and doorway entry and along corners of the ceiling and cracks. It’s also effective for other types of insects. It’s a good barrier and adds a layer of protection.

It seems that most of the negative reviews are from customers who do not understand what this product is or how it works. Let me be clear: THIS. IS. NOT. RAID! It's actually better! Raid is a chemical substance that is designed to sicken and kill insects almost instantly upon contact. Which is great if you happen to see the bugs and spray them before they scurry away. But what about the other creepy crawlies that might be lurking elsewhere in your home? Bugs, especially ants and roaches, rarely travel alone. So if you see one, chances are there are others that have yet to reveal themselves. And Raid will only get rid of the bugs that you happen to find and spray yourself. Ortho, on the other hand, isn't designed to kill the bugs immediately. Instead, it infects the bugs with a slow-acting poison that might take hours or even days to actually kill them. How is this a good thing? Because it gives the bugs plenty of time to return to the colony and infect the others with the toxin that clings to their bodies. In my opinion this product is better than Raid because it doesn't require you to find the bugs yourself. Just spray around the areas where you have seen the most bug activity (i.e. basements, bathrooms, kitchens, etc.) and voila! The bugs are doomed. Granted, it takes time and patience. Depending on the severity of your infestation, it might take weeks or even months for your home to become completely bug-free. However, you should probably take into consideration that even an overpriced exterminator can't rid you of your bug problem in one quick visit. Most exterminators make frequent visits to your home where they will charge you out the nose just to spray down your living quarters with an almost identical product. Call me crazy, but I'd rather cut out the middle man and save a few Benjamins by doing it myself instead of paying a stranger to come into a house every week to do it for me. I hope this review clarifies any confusion that someone might have and provide future buyers with a better understanding of what they're actually paying for. Update: Something I forgot to mention in my original post is the importance of keeping a clean and dry home. The poison works by attacking the bugs' immune system and making them fatally ill. And just like humans require food and lots of fluids to recover when we're sick, so do bugs. Keeping your home dry and clean as possible will allow the extermination process to work much more efficiently.

It’s not bad we’re supposed to keep them away for I think at least two months or something like that but they did not work all the way so take what you came from that

So far this bug spray has worked very well. It sprays in one fine line very neatly no aerosol effect. I would definitely buy this product again. I've used Bengal bug spray in the past and although it works exceptionally well it is also not great if you have children and animals. This has minimal smell and is easy to use.

I bought this to get rid of ants. My house had an ant infestation a few days ago. This insecticide is odorless, and the electric spray gun sprays liquid, not mist. While this spray gun is easier to use than an old manual spray gun, once you're done killing the insects, once you unplug the connecting hose, the electric gun stops working. This causes the pesticide to constantly leak out of the spray gun and the delivery hose. I don't know how toxic this insecticide is, but it's hard not to get caught in its liquid.
