What Customers Are Saying

Customers are sharply divided on this product. Many praise its lack of chemical odor and ease of use, with some reporting immediate results like dead insects and lasting effectiveness. However, nearly as many report severe sprayer wand failures—producing no spray, only noise, or leaking after one or two uses—leaving bottles unusable. Others note inconsistent insect-killing performance, seeing live pests days or weeks after repeated applications, or success against certain insects but complete failure against others. Overall, functional reliability issues overshadow the positive odor and usability benefits for most reviewers.

Nice

[This review was collected as part of a promotion.] I’m worried about using this with my cats and in my kitchen but I plan to test it out on some indoor ants soon. Definitely excited for the purchase and I’ve used this before so it will work well.

Safe for those with pets

[This review was collected as part of a promotion.] Our ant entrance tends to be concentrated to the back deck door as that is where the dog bowls are and it seems to attract them. A few sprays around the door and our ant problem is gone! And it’s safe to use which is a huge plus with multiple animals

Highly Effective Both Quickly and Longterm

[This review was collected as part of a promotion.] The Ortho Home Defense Max Indoor Insect Barrier spray was very easy to use, quick to dry and requiring no cleanup afterwards, and with no scent. Within 15 minutes of spraying along my windowsill, any bugs entering were already dying and in the following days/weeks, the appearance of bugs decreased almost 100%.

Best spray feature for a bug product I have used!

[This review was collected as part of a promotion.] This product was ridiculously easy to use! I love the spray feature! It works so perfectly and covers such a large area. Comes with a refill and minimal packaging. Used this around the perimeter of my home, particularly by the windows and back doors where we have an ants and have seen a huge exclamation the product has lasted and we have not had to respray for almost a month. Definitely recommend

Fast acting

[This review was collected as part of a promotion.] Home Defense from Ortho works hard and fast to keep insects from entering the home, the easy to use solution in a handy spray bottle that makes it mess free and very effective. The product doesn’t contain any harsh odors and is refillable.

Odd

[This review was collected as part of a promotion.] There are zero instructions on this which I found baffling and potentially dangerous. Yes i can just spray to my heart’s content but actually instructions on where to aim or how far away would make sense

Spray those insects away with an easy to spray bot

[This review was collected as part of a promotion.] Perfect east to spray insect barrier. With the warmer temps coming the bugs and insects are finding their way inside. This was perfect timing. I used the spray around windows and door frames. Easy to spray nozzle. Light and hardly a smell. Love that it comes with a refill bottle, so you can just use the top for the refill less waste and mess. The spray worked well and it didn’t leave any residue behind.

Great for ants

[This review was collected as part of a promotion.] We were having a serious ant problem so we used this. It was easy to spray and did not leave any stains on the deck or patio after it dried. I felt safe using it around the house. We noticed not long after we sprayed that we stopped having ants in the house so it was very effective. I would use this product again.

No messy residue

[This review was collected as part of a promotion.] Considering this is the time of year I spray my house, the Ortho Defense arrived at the perfect time. As I applied it throughout my home, I noticed very little fumes and the trigger spray applied evenly. To my surprise, the leftover residue was minimal, nor did it stain my baseboards/floors. So far, so good, I haven't seen one bug!!

Great bug spray

[This review was collected as part of a promotion.] This worked super well! It was a breeze to use from the nozzle and it had great spray coverage. I like how it’s not massive so it was easy to store and didn’t leak like most of these do. Also bonus that it didn’t have a gross chemical smell.

Works well!

[This review was collected as part of a promotion.] I sprayed the perimeter of my garage and I’ve found tons of dead spiders. This product works well for indoors. I also sprayed the perimeter of my porch outdoors. I saw a reduced amount of bugs. But may need something stronger for outdoor use.

Works well

[This review was collected as part of a promotion.] Ortho indoor insect barrier has been helping with the spiders and ants. It doesn’t have a strong smell and dries fairly quickly. It’s not a giant bottle so it’s easy to store.

Good product, bad smell

[This review was collected as part of a promotion.] I used this spray at the entrance of my doors, I like to keep them open in the spring. While it’s fairly good at keeping out bugs, the smell does put me off.

Convenient

[This review was collected as part of a promotion.] I really like the refill bottle that came with the Ortho insect barrier. It was convenient to use and I like the continuous sprayer. It had great coverage. I sprayed the baseboards of my indoor stairs as I often find ants there and after spraying I haven’t seen any! I’m excited to use in the future for spiders cuz I do not like those! lol

Bug be gone

[This review was collected as part of a promotion.] I have sprayed this product on all my doors and windows and instantly noticed the difference. As the weather warms up, the bugs in my neck of the woods swarm, but luckily it’s only outside now
