Easy to apply and already seeing fewer bugs
We bought this after moving into a rental that had way more spiders than we were comfortable with. The battery-powered wand made it really easy to apply around baseboards and entry points without making a mess. It dries quickly, and I appreciate that once it’s dry it’s okay to use around our toddler and dog as directed. It’s only been a short time, but we’ve already noticed fewer bugs inside. I’d definitely buy it again.

Must but
Great investment I bought this for my kitchen because roaches were an issue no matter how clean it was kept. And now if I see one it’s a miracle. I spray once a week or when I see even just one. It’s odorless and was surprised how fast it works. It continues to work after it dries a use it mostly in my door was inside and out kitchen and bathroom. They just drop dead after a few seconds. Definitely a must buy

Easy to use and effective
I have bought two of these. One for my own place and one for my parents place. There is plenty of solution so this will last a long time. I bought this originally because I had a flea infestation that all natural remedies had not taken care of and I wanted to make sure it wouldn't be toxic to my cat or anyone else. The wand makes it easy to spray and cover large swathes of area without your finger getting tired. Just be aware if you are spraying upwards to maybe wear eye protection and a mask so that you don't accidentally ingest or absorb any of it just in case. The bugs in my area are very stubborn so I did have to reapply after a month but after two applications, I didn't see any bugs until a year later. I am sure if I reapplied, it would have worked for another year. I definitely recommend as it seems to really have helped with the presence of bugs and once dried, I don't have to worry about the chemicals. I've lent it out to friends to use and it seems to work just as well or better for others. I highly recommend this with the wand since it makes application so much easier.

Contract Quaility with out the contact!
I’m really happy with Ortho Home Defense Insect Killer for Indoor use! 🏡✨ It’s a great alternative to paying for a professional service and getting locked into a contract. I love being able to handle it myself whenever I need to without the extra expense or commitment. It’s easy to use, helps protect my home from unwanted pests, and gives me peace of mind knowing I can take care of the problem on my own schedule. A great value for anyone who wants an effective solution without the hassle of a service contract. 🐜👍🏾

Finding a remedy to a disgusting problem
When I moved into my new place I found out that I had extra gifts spending the night evidently, critters called roaches. The stuff that the property uses clearly does nothing whatsoever. So now I'm on a quest to find the best thing that I can to get rid of these disgusting things. This spray doesn't kill on contact but it kills after they keep walking through where it's been spraying, if I'm understanding correctly. After week I took everything out after the initial spray and sprayed the area again, placing everything back in the cabinets after it had been washed wiped down etc. so far all I'm seeing is a few roaches with a few babies. Which I guess I'm going to have to take everything out again and respray everything down since it is better than when I first moved in the first night. So so far I am more pleased than when I first moved in and considering the dead bugs I'm finding when I go in after a week to vacuum and clean everything out, I am thinking that I'm going to be pretty happy with this. The sprayer that comes with it is convenient and makes it super easy without having to do contortions to reach the top of cabinets. It also doesn't seem to have any negative odor that I have found. So so far so good and I would recommend it.

Odorless, colorless. Works well.
Got this for daddy-long-leg spiders. Did a great job of quickly ridding them. And, other insects as it turns out. No odor, colorless, dries quick, and so far lasts quite a while. I use it indoor and outdoor. Satisfied with this product. Handy spray mechanism.

Effective
The product itself is good. Amazon, however, lacks finesse in packing it for shipment. It’s obviously a heavy item. And due to it rolling around freely in a cardboard shipping box, the spray wand got snapped during shipment to me

My Go-To for Keeping Roaches Out
Every year when the weather starts heating up outside, the roaches seem to try making their way into the house. I've been using Home Defense Insect Killer to spray the perimeter of our home, and it has become part of my regular routine. After spraying, we might see one or two dead roaches inside the house over the next few days, but after that, nothing. It does a great job creating a barrier and stopping them before they become a bigger problem. What I like most is how cost-effective it is. It's way cheaper than paying for regular pest control service, and I've had great results handling the problem myself. One bottle goes a long way and helps keep the bugs where they belong—outside. I've used this product multiple times over the years with consistent results. Highly recommended and definitely a 5-star product in my experience.

Expensive but good product
Have used this product before in the Caribbean. No roaches or the like for 5 years so I know it works. Pretty hefty price tag though for shipment to the UK when much lower price on the other side of the pond. But the heart wants what the heart wants…
