Buena calidad
The best thing about Ortho Home Defense is its convenience. The electric sprayer works wonderfully and saves you the effort of using manual sprayers. It leaves no odor or stains, and it truly delivers on its promise: it keeps ants and spiders out of your house for months. Highly recommended for preventative home maintenance.

Works Fast and Keeps Spiders Away
This spider spray works exactly as advertised. I’ve noticed a big decrease in spiders around the house since using it. It sprays easily and covers corners and hard-to-reach areas without leaving a mess. I also appreciate that it dries quickly and doesn’t leave a strong chemical smell lingering. It gives me peace of mind knowing my home is safer for kids and pets (after following the instructions). Effective, easy to use, and worth having on hand if you want to keep spiders out of your home.

Goodbye spiders! A true perimeter lifesaver
If you're like me, dealing with those seasonal pest invasions is the worst part of home ownership. My specific nightmare is a never-ending battle with spiders around the foundation and those little rolly pollies (pill bugs) trying to march into the garage. After years of trying different solutions, I finally found a winner with Ortho Home Defense Insect Killer. I mainly used this product to establish a barrier outside my house, and the results were almost immediate. Seriously, within a day or two, the creepy crawlies around the door frames and patio areas were gone. I haven't seen an unwelcome spider web near the entries in weeks! The fact that it provides up to 12 months of protection indoors against ants, roaches, and spiders gives me great peace of mind, even though I've focused on the exterior. The best part, hands down, is the Comfort Wand. No more tired hands from constantly pumping a spray bottle! This wand delivers a continuous, steady stream, making it super easy to walk the entire perimeter of my foundation and get into all those little cracks and crevices where pests love to hide. It made applying the treatment feel like a quick chore rather than a major headache. It’s easy to use, highly effective against the common outdoor invaders I struggle with, and keeps my home feeling mostly pest-free. Highly recommend this for anyone needing a reliable pest barrier! Overall, here are some pros and cons you might find helpful... PROS: Instant Results: Noticeable drop in pest activity (especially spiders and rolly pollies) within 1-2 days. Comfort Wand: The battery-powered wand makes application effortless and quick for large areas. Long-Lasting Barrier: Offers up to 12 months of protection indoors, reducing the need for frequent re-application. Great Coverage: The size is perfect for treating a full home perimeter, decks, and common indoor problem areas. CONS: Odor: Like most sprays, it has a noticeable odor during application. Waiting Time: You have to wait for the spray to completely dry before letting pets or children back into the treated area. Surfaces: Treatment might not last as long on raw concrete or wood.

World War Bug
I have never heard of pantry moths but I am so glad I had this when I discovered them. The way I rained this down in my pantry and had a full scale battle. Anyways I won and this took care of the problem. I’m summary, this is very effective, the spray function was amazing, it killed the bugs too. 10/10

Must have pest control
My friend suggested this brand, so wanted to try it and I’m really satisfied. Initially got this delivered with a broken handle but Amazon sent a replacement within a day. Thanks Amazon for that! Also, this product’s design is so convenient to use as it comes with an electric sprayer and included battery, so it’s ready to use. The nozzle has 2 adjustable levels for the spray quantity. Tried it in my garage and porch, I can see the effectiveness and results the next day itself as the bugs are dead. They’ve included the list of bugs it can kill in the attached booklet and that’s a lot! They’ve mentioned that it’s safe to use indoor as well, there’s no bad odor, stickiness or messy marks left behind. And the quantity that Amazon seller provides is good enough to cover the entire house and value for money. They’ve declared that it’s effective for a year and I hope it protects the same way. Overall it’s a must to have pest control product for the house.

Works Well, Doesn't Smell
I spray this around the perimeter of the house and around the windows and doors outside and some inside. It has been effective for the ants. They were coming in through the tops of windows and doors. I don't notice a smell and it seems to be clear. I also spray around the planters outside because that is where the ants were living. This defense lasts about a year. I have not seen an ant inside the house since. I also spray around the shed. If you see ants, you should follow their path to see where they are coming from. And also keep food in airtight containers.

Decent Insect Killer, but Hit or Miss Performance
I’d call this insecticide average overall. It definitely has its strengths, but also a few frustrating downsides. On the plus side, it’s effective at killing ants, roaches, and spiders, and I like that it’s odorless. I used it around the kitchen baseboards and outside near my patio door, and it knocked out a small trail of ants almost immediately. I also sprayed a few corners in the basement where I’ve seen spiders, and it seemed to keep them away for a while. The ease of use is great, just spray and go and I appreciate that it’s cheaper than hiring a pest control service. The quality feels solid, and when it works, it really works. Some customers mentioned it lasts up to a year, but in my case, I’d say the effect wore off after about two to three months. So, the longevity isn’t quite what’s advertised, at least not for me. My biggest gripe is with the sprayer itself. The nozzle on my bottle stopped working properly after a few uses. Sometimes it wouldn’t spray at all, or it came out in uneven bursts, which made it annoying to apply evenly. I had to transfer the liquid into another spray bottle just to finish using it.

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…
