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. 🐜👍🏾

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.

Effective and easy to use! A must buy for pest problems!
I don’t normally leave product reviews, but I felt compelled to for this home pest spray. I was genuinely surprised how easy to use and effective this sprayer was. My house was infested with black widows, spiders, and large cockroaches that would leave tons webs and eggs all over the property. After reading reviews, I decided to try this ortho spray. It was very easy to use and apply throughout the property. A few days later, I found tons of dead bugs near the areas where I had spray. Not only had it effectively killed these pests, it also effectively kept them away from my house. I haven’t noticed any new webs, insects, or eggs around the house. I highly recommend this to everyone. Way cheaper than pest services and works great for its purpose.

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.

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.

Works great
I sprayed this around the exterior of my house, including around windows. I was smashing multiple earwigs daily in my house before. I had even found three cockroaches inside within about a 2-week span. It seems to be a bad year for pests. But now I've only found one earwig inside and no cockroaches in the 5 weeks or so since spraying this. The wand is very handy and easy to use, and one of these containers was a good amount to thoroughly do the outside of my house. Way more affordable than hiring a pest service, effective, and easy!

This is the best product
This stuff is amazing. I moved to a wooded area where spiders and all kinds of insects would crawl into my place from my patio door. I saw reviews on it so I decided to try it. It’s been almost six months and I’m blown away with how well it works. I just sprayed it all around the inside of my patio door and around window areas. It kills all the creepy crawlers trying to sneak in. I haven’t seen a living spider inside my place and will see a few dead ones around the entrance but it works. I spray it periodically on the outside of my door just to add a little protection but with rain not sure if that makes a difference but I would give 10 stars if I could.

I love this stuff
It helps with ants . It kills them instantly. I never see it leak. It has 3 ways to turn it off. You turn it off where the wand connects. You can turn the wand to off and you can shut the trigger off. I sprayed the outside of my house with it. You don't smell it or see it after it dries. I think it is a great value and very effective at keeping ants away.

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…
