Ortho Home Defense Insect Killer has been an absolute game-changer for maintaining a pest-free home. As someone who has tried numerous insect control products over the years, I can confidently say that this is the most effective and convenient solution I've ever used. The combination of powerful pest control and user-friendly application makes it stand head and shoulders above competing products on the market. The Comfort Wand application system is brilliantly designed and makes treating your home remarkably easy and efficient. The wand extends your reach and provides excellent control over where the product goes, allowing precise application along baseboards, in corners, around windows and doors, and in other areas where insects typically enter or travel. The battery-powered spray mechanism creates a consistent, even application without any pumping or manual effort. This means I can treat my entire home's perimeter and problem areas without fatigue or inconsistent coverage, which is a huge improvement over traditional pump sprayers. The effectiveness of this product against a wide variety of common household pests is truly impressive. I've used it successfully to control ants, roaches, spiders, centipedes, and other crawling insects that occasionally try to invade my home. The results are both immediate and long-lasting. Within hours of application, I notice a dramatic reduction in pest activity, and the protection continues for months. The product creates an invisible barrier that insects cannot cross without being affected, providing ongoing protection that prevents infestations before they can establish themselves. One of the features I appreciate most is the indoor and perimeter dual-use formula. I can use the same product both inside my home and around the exterior foundation, doors, and windows. This versatility eliminates the need to purchase and manage multiple products for different applications. The indoor formula is designed to be used safely in living spaces when applied according to directions, and it dries quickly without leaving visible residue or strong odors. This makes it ideal for treating areas where family and pets spend time. The coverage provided by the large bottle is exceptional. The gallon size treats a substantial area, making it economical for whole-home protection and perimeter treatment. I typically treat my entire home's interior baseboards and exterior foundation with one bottle, with enough left over for spot treatments as needed throughout the season. This excellent coverage means fewer trips to the store and better value compared to smaller containers or more expensive professional treatments. Application is straightforward and requires minimal preparation.

This is a solid product. This is not designed for infestations or ant hills. It is a product designed to prevent entry of insects into your residence and eliminate individual insects that have entered. While this may help the odd case of colonized insects, it really is made for those solo runners that snuck in when you weren't looking. If you have an infestation or a mess, your insects are doing more than entering your house, they are living in it. Perhaps if it was sprayed around the house like the floors were being watering your floors it would work on infestations...but, PLEASE DON'T DO THAT, it wasn't designed for that use nor was that dosage tested for human/animal exposure. Consider calling an exterminator for infestations (100s+, colonies, groups of insects, etc.). And as for ant hills, either remove them, or buy poison for ant mounds. Are there ant hills in your home? That seems like a different problem. After you've taken care of cleaning things up, then protect your residence from the entry of new insects. You'll see this product is WONDERFUL FOR THE JOB. I've used it for years, one home in a very wooded, shaded area, one home in the south. Works like a charm...spraying as others have mentioned...seasonally. This product works by leaving a residue, so if what you spray it on (baseboard, perimeter of home covered in leaves in the fall, edge of home outside, etc.) is cleaned, blown away, excessively rained on...some or all of that residue will be removed...particularly overtime. Be aware of your specific situation and adjust your application frequency accordingly. IF YOU CREATE A BARRIER, THEY WILL NOT ENTER. (Read the label for all the insects covered...it's extensive.) 1. Clean up your outside and inside space a little of non-permanent items, pulling things from the perimeter (toys, anything that shouldn't be on the floor or ground basically). Eliminate debris and items in which insects hide, make webs, etc. 2. Spray the OUTSIDE perimeter and along the border of every door and window. 3. Spray the INSIDE perimeter, along the base boards, of your whole house (closets, pantries, bathrooms included). Then spray a barrier between rooms (around the door frame). Lastly, I understand the frustration that might occur if your wand or applicator never came. Exchange it with Amazon, try a spray bottle, etc. I've been using this with pets. Label says that IT MUST DRY BEFORE IT IS OK WITH PETS. Please remove them from the area while you apply. If you have a pet roach or tarantula I don't know what to tell you. All the best, and good luck with your application.

Seemed to work. Been in a new house, and earlier this summer, we were getting a cock roach encounter almost nightly all of a sudden. Our cats are very good at detecting, finding, and playing with them, otherwise I don't even know if we'd of known. I put this stuff around the house outside, I did the inside of my garage, both around the walls and the garage door, and also in the gaps between the concrete rectangles. Got those same gaps down my driveway leading to the garage as well. Still had a few encounters initially, but they slowed down, and basically stopped. Might get 1 every 3 to 4 weeks now. I started finding bodies in the garage every now and then, and that stopped too. This stuff doesn't kill these insects instantly, it seems to hurt them over time. Ones you find, will be slower, sometimes basically dying. I did not spray inside, aside from the garage. I was going to spray inside, if we didn't see results, but it seemed to have worked. Either the spray worked and has done wonders, or the pests may have been a time of year thing, or related to construction in the area, I'm not sure. But as far as I can tell, this stuff worked for us. As for the amounts, I have a 1 story, 1950 square foot house, and I was able to do the entire house perimeter, the inside garage , the driveway, and I was left with what feels like half, or just under half left.

TLDR; It works if you make an actual barrier and employ common sense. Also give it 2 weeks to see actual results. Any bugs trapped inside your barrier will have to be dealt with by some other products be it bait or whatever for your situation. But this stuff prevents future entry from taking place. Read the full review below for extra comments on how to get it for a best case. Thanks for your time. **Full Review** First of all I just want to apologize to Ortho for my poor review originally. I hadn't given it enough time to prove it was worthy of becoming a subscription product. I ordered this back on June 17, 2019 for general bug barrier needs. earwigs, thousand leggers otherwise known as centipedes, spiders, more spiders, even more spiders, the odd roach, the various species of ants, crickets, slugs, the amount of slugs we get is astounding.. and did i say spiders?? Upon first application, it appeared the bugs didnt like the stuff, but it didnt seem to do much other than startle them. But I applied as directed and as I thought fit. (make a barrier like a rectangle around door frames and a line at the foundation and on the brick) Well I also sprayed some around where the spiders like to gather. This is the area I began noticing a massive reduction in over 2 weeks after the spray application. If you have CCTV cameras that continually need clearing because the spiders made webs in/on the lenses or in front of because of IR lights. THIS STUFF WORKS LIKE MAGIC FOR THAT!! You wont need to reapply for probably 3-6 months depending on if the cam gets rained on/super sunlight etc. You have to remember, This is not a "contact killer". This is purposely formulated as a "BUG BARRIER" which basically means it is a forcefield for your home if you use it properly. This means if you have leaves and messes all around your house as a perfect breeding ground for various bugs and a way to bypass the barrier, You are going to have to clean that up to have a chance at keeping bugs out. If you're lazy like me. Just move the stuff off your house. Give it a good foot of space between the bushes, and messes, and leaves. Put the wand on the wide spray mode and go around your whole house spraying a perimeter (thick one) on the base of the bricks and concrete floor or dirt. Just dont use it around any plants which have edible fruits.... or veg. Spray rectangular barriers around the doorways. Be careful not to drip it on you. Wear a mask. Wear gloves. Wear a long sleeve shirt. Do what you can to avoid contact. The product leaves behind a residue that the bugs straight up avoid. Think of it as an invisible chalk line. When it rains if theres a spot in the open it will be washed away sooner than the spots that have no rain contact. That's just nature. You WILL have to reapply as necessary every 2 to 3 months in those spots. Maybe more often. Maybe less often. You have to make that determination on your own. Overall I wish the stuff was more potent for the already existing bugs. If it could kill them quick, as well as create a barrier for future generations of insects. That'd be perfect. But for the job it was designed for. It does a 4 star job. **Original Review** Sprayer is just about the ONLY good thing about this product. I sprayed around the garage door as a test right on multiple species of spiders and other insects, they walked like nothing was wrong. seemed to not want to cross the line i drew on the brick of the foundation but then within 24 hours i checked again and bugs were crossing like it was a highway. I even did a thick line at the bottom of the doorway and just.. doesn't work. Save your money and go elsewhere.

I love this stuff!! I've been using it for years now. I live in the desert and every summer I battle the ants, the roaches, and just all bugs in general. Its like battle of the bugs up here and this is my defense. It really works. And they've got great customer service too. One time one of the wands arrived broken and they sent me another, Easy Peasy. I do have a small child and a small dog In the house as well, so I just keep them away from it while it drys as directed per instructions and I have not had any problems. Im a repeat customer for this product. No joke. I recommend this for ants, roaches, flys, or any other bug problem that I can think of. Try it out. U won't regret it and your welcome.

So I used this like last week to get rid of spiders by my window. They keep setting up shop there. I went back today and sprayed again, expecting them to be back. Because that’s the usual for when I spray some repellents. After it dries, their webs are back up. But it wasn’t even one spider there. And it was some big ones before(california big. Not Australia). So I didn’t fully spray. Just one area but I quickly realized no spiders so I stopped. So this is a short term review. I’m going to set a reminder in my phone to check it in 3 months. I know it is advertised to last longer. But I want to check it at 3 month intervals, to see if it’s still working. Of course if it rains, the experiment is over lol. So I’ll come back in 3 months for an update. Mid Edit: As of 09/10/23, there’s still no spiders. And there are no huge spiders around where I live. Like a tarantula, wolf, or huntsman. Not that I’ve seen at least. This is a spider repellent review. Not a flamethrower review lol. And it rained from the hurricane/tropical storm that passed recently. I guess it didn’t hit the area directly or it wasn’t enough to wash it away. So that’s good it lasted this long. I’ll come back near the end of October for one final update. But I’m already sold with it lasting over a month. 10/23/23 Final update. Still no spiders outside my window. So it works for at least 3 months, which is good for me. One thing, don’t spray it in high bug areas like outside trash cans. I sprayed my outside trash cans because I don’t like touching spider webs when taking out the trash. Next time I’ll just spray the handles or something. Because there were so many more flies in and around the trash after there were no spiders left around there to catch them. So just be mindful of that. AND, it didn’t repel the flies. So it worked for spiders, not for the house flies. Edit: 05/05/2024 I had no intentions of doing another edit. But I was so impressed I had to. I went out to spray my window again just now. And there were no spiders or other insects where I sprayed. No spider webs or anything. After rains, winds, time, and it’s living up to the claims so far of being long lasting defense. I just thought that was cool. This is the last update though. Because I sprayed it again even though it wasn’t needed. I was trying to see if a spider would come running out from where I couldn’t see it or something. lol nothing ran out. I wish it worked better for flies. But this is a must to keep handy if you deal with a lot of spiders. Oh. Side note. It hasn’t messed up my paint either. But this is a case by case basis. Do a spot check on your intended surface to test it first, if concerned. Ok. That’s all. Thank you for reading. Have a good day edit: June 1, 2024. I sprayed in the doorway because spiders kept going there. They would come every couple of weeks. I sprayed and within 2 days I saw 3 spiders right where I sprayed. Didn't phase them at all. The daddy long leg ones. Not sure why it works so well for the outside spiders and not for the long legs. But hey. If I had to choose which spiders I wanted to stay away, it's definitely the ones outside. still disappointed though.

We enjoy a summer rental and ants seem to be a reoccurring problem each year but after two treatments, I haven’t seen a living ant in two weeks. The lesson is, continue to treat every week for two weeks then monthly and your problems are solved. Battery operated sprayer is a real plus with a directional nozzle. Highly recommended Update 7/20 As I was preparing for this week’s treatment, the sprayer stopped working and after some troubleshooting there was still no suction with plenty of battery power. I write to ortho and here’s their response; Be sure that the end of the hose is firmly attached to the cap. Push on it until a distinct “click” is heard. The “click” indicates that the hose is attached correctly. * If have a spout on the container cap that flips up, make sure it is fully flipped up so it is straight up and down and not at an angle. * If have a knob on the cap, make sure it is turned to the "ON" position. When fully in the "ON" position, you should feel the knob click into place and the arrow on the knob will point to the middle of "ON". * Make sure that the wand is open and locked into position. * Check that the nozzle at the end of the wand is turned to an open position. There are either 2 or 3 open positions and 1 or 2 off positions (depending on wand version). * There is a lock on the trigger. Make sure that the trigger lock is not in the locked position. * Occasionally, some crystallization can clog the sprayer. After disconnecting the red plug from the cap soak the spray tip/nozzle in warm soapy water. This may dislodge any crystallized matter. The sprayer tip can be readily pulled off and snapped back on after cleaning * If this is the first time you have used the wand, be sure that the plastic protection strip has been removed from the battery compartment. The batteries will not engage until the plastic strip has been removed. * Batteries have a shelf life that will last through approximately two 1.33 bottles. It is possible that the batteries need to be replaced. The unit holds either 3 or 4 Double-A (AA) batteries (depends on the wand version). Replace the old batteries with fresh ones to see if that fixes the spraying issue. * If the sprayer motor is running and all of the above troubleshooting has been completed, the sprayer may need to be re-primed. To re-prime, place the container above the wand (either holding it above or setting it on something) and spray for 30 seconds in an area where the product can safely be dispensed. All Good advice but none of that helped with my issue. I write to Amazon and they immediately offer a no fuss replacement. This is why I love Amazon- Excellent customer service and they will continue to have my business.

To be honest, I have used this for over six months now and I still see small and large roaches around my apartment. So it's not really getting rid of the root of the issue, however, it seems that whenever I spray, they go away for a few days, sometimes weeks, and then I start seeing a bunch of dead ones appear. Hard to tell how effective this really is bc i'm not a bug guy, but it's done a decent job for the price. Maybe it's placebo. No smell and dries up quick.
