Review: Works great for palmetto bugs - When I moved in to a new rental house, I was thrilled! Until I met the palmetto bugs of south carolina. They're big, spooky, and were everywhere outside. I had to get rid of them. I had little sticky traps before and I was changing the traps every few days just from how many of these there were. I began spraying this on my screen porch and immediately sprayed one of the palmettos, and in 10 seconds it flopped on its back dead. So far so good. I started establishing a perimeter around my porch and then slowly expanding the perimeter as I moved outwards. After about 30 minutes of spraying I wasnt even close to being through the bottle but I was satisfied with my coverage. I let it dry for an hour and I was literally amazed. 4 dead palmettos already. And I wasnt terrified of going outside on the porch to just enjoy the outdoors in fear of a giant skittering creature. I then moved to the front door and began spraying there as well, putting down a good perimeter again. I noticed there were no more spiders after a day as well. I've only seen one palmetto since which I chased down with the spray and reinforced my perimeter again about a week after initial application. It most definitely works For me, its worked on stinkbugs, palmetto bugs, ants and spiders. I'm no amazing pest controller and I know there have been some holes in my perimeter but I've just sprayed a little more when I find somewhere I've missed and this stuff has been great! I do need to start in on the source of these palmettos which is the space under my porch (I suspect) and potentially the crawl space under the house which I have no access to. But I can get under the porch with a longer sprayer and I'm confident that by the end of spring, I'll be palmetto free!
Review: Amazing! Can't live without it! - We live next to water and we have a parking lot light attached to our home directly next to an upstairs window. Needless to say, we are engaged in a constant battle to keep insects and bugs out of our house and away from our doors and deck. This stuff works like a miracle! When we bought our house, the previous owner had left the place vacant for two years. There were generations of creepy crawlies that had infested the bushes and under the deck. It was impossible to go outside without getting covered in spiders. It took about a year, and I had to strategically apply this stuff around the house in areas where they'd remained deeply hidden, but it worked! We hardly see any bugs or spiders anymore. And we can actually use our deck now! Now, I treat the interior and exterior perimeter, the windows, door frames, and any potential entry points and hiding spots once a year around Fall. And I do just the perimeters again at the start of Spring. We live in a condo with neighbors on each side, and I can tell you the exteriors of our homes look very different! Ours isn't covered roof to foundation in spiderwebs, and we honestly get zero bugs indoors, not even in the basement.

## Questions & Answers

**Q: Does it kill bed bugs too?**
A: Steam cleaning kills bed bugs. This spray is good for preventing a reoccurring problem, after you kill the live ones and eggs with high-heat steam.

**Q: Is this safe round infanst and pets**
A: Just to be on the safe side, I would make sure pets and infants aren't in the treated area, when actually being treated.  However, I haven't seen any side effects in my dog.

**Q: What is the difference between ortho home defense indoor and perimeter2 and the ortho home defense max?**
A: I was about to write a review as I use both products, and saw this question and decided to give a valid answer as others may want to know.

They are basically the same product as mentioned, however they have different uses and different chemicals/amounts for that purpose. While ortho is good inside the home, MAX is better used outside the home (and inside) but in order to benefit from it you need to spray it on hard surface next to your house, tile, concrete doors, windows ect. That is why I am lining my home with 2-3 ft of crushed white rock or concrete because in order to be effective the surface needs to be 1) solid for the MAX to stick to and 2) smooth and at least 12IN for the spiders/pests to cross. But as I stated I use both Ortho inside and MAX around the outside and the MAX does provide 12 months of protection while the Ortho I believe is only 3 months.

**Q: Is this for inside of the home only, in other words is this for outside and inside and if only one do i need a different spray for the other?**
A: I use both inside and outside.  It is clear and does not stain or stink.  Inside I only do exterior doors and window sills although you can do baseboards as well. Hope that helps.

### ⭐⭐⭐⭐ Promising Start with Ortho Home Defense Insect Killer
*by K***E on August 20, 2023*

I recently purchased the Ortho Home Defense Insect Killer and have been using it for a short while. While it's still too early to make a definitive judgment, I'm already seeing promising results that warrant a positive review. The trigger sprayer that comes with the product is convenient and easy to use. It provides a consistent spray, ensuring even coverage across the surfaces I'm targeting. The non-staining and odor-free formula is a big plus, as I can apply it without worrying about leaving marks or unpleasant smells around my home. In terms of effectiveness, I've noticed a decrease in the insect activity around my home. While I can't say for certain that all the targeted pests are completely gone, the reduction in sightings of ants, cockroaches, and spiders is a positive sign. Fleas and ticks have also become less of an issue for my pets, which is a relief. The long-lasting control claim is something I'm looking forward to witnessing over time. If the product continues to deliver on this front, it will definitely solidify my positive impression. The 1-gallon size is generous and should last for a good amount of time, even with repeated applications. This makes the product a cost-effective solution for indoor and perimeter insect control. While it's too early to provide a final verdict, I'm optimistic about the Ortho Home Defense Insect Killer. If the positive trends I'm seeing continue, I'll certainly consider upgrading this review to a full 5 stars in the future.
