What Customers Are Saying

Customers overwhelmingly report serious defects with the sprayer mechanism, which frequently fails after just one or two uses—stopping entirely, leaking upright, or making noise without dispensing. Many own multiple full containers rendered unusable due to faulty sprayers. Beyond mechanical failure, reviewers express deep frustration that the product fails to control pest populations, with roaches, ants, fleas, and silverfish returning within days or weeks despite reapplication. The 365-day protection claim is widely mocked as barely lasting hours. A small number report temporary success with specific pests, but these isolated positives are vastly outweighed by complaints about unreliability and ineffectiveness.

Easy to use effective bug spray

[This review was collected as part of a promotion.] It does seem to work well with easy maintenance. Safe for my family in my house. The container is not large but goes a long ways. I did not notice any residual.

Works good

[This review was collected as part of a promotion.] Plastic spray bottle. I like that it has a continuous spray pump. It seems to be working. It's definitely keeping the pest out of my house. Even keeping those crazy stink bugs out.

No fumes, smell or harm to surfaces in our home

[This review was collected as part of a promotion.] Spring is full of insects coming back into our home, I'm happy have gotten this and tried it out on not only the ants, but the spiders and mini ants we always have. Spraying it with no chemical smell was nice! I didn't have any reactions to fumes or smells, it wasn't greasy or heavy either. Ortho Home DefenseMaax Indoor Insect Barrier and refill killed the ants and spiders on contact! Rural areas are known for a varied amount of insects so watc...

Ladybugs GONE

[This review was collected as part of a promotion.] I’ve struggled with LOTS of ladybugs in my house, especially close to my bay window. I started using Ortho Indoor Insect barrier and it has significantly reduced (or even eliminated) the lady bugs! The product is very easy to use, a very soft mist. There is no odor, and I feel good that is safe to use in areas where my cats and children play. I couldn’t recommend this product more, and it will forever be a staple in my house!

Insects Be Gone!

[This review was collected as part of a promotion.] Love how easy and user friendly this indoor and outdoor and when the container is empty I have the refill bottle. I sprayed it at my sliding door as well as by my window where we have ants and other critters that can come in. Living right by the creek and woods and living by an even bigger woods in my backyard we get bugs easily and they are a problem especially in the winter and early spring. I found that since spraying this product there has ...

Keeping bugs out

[This review was collected as part of a promotion.] This product is something I think we will definitely continue to use! As we are coming into spring we start noticing a few more bugs lurking and it’s already noticeable how there isn’t so many. Great option. Like the spray feature to make it a little easier to use. Instructions are clear and to the point. I don’t care for the scent but it’s not over powering

Easy home protection

[This review was collected as part of a promotion.] We were looking for protection against insects in our home now that Summer is coming. Ortho is a great brand that had worked in the past. Easy to use to keep our house bug free. Thanks!

Its sprays house down!

[This review was collected as part of a promotion.] This Home Defense Max Indoor Barrier with refill by Ortho is safe for indoor use. Features include 360° spray, no staining nor fumes. It lasts for a full year, so the barrier keeps preventing and killing pests. It has a special formula to dry quickly. The active ingredient is biofenthrin which is low in toxicity. It interferes with the nervous system of insects. Once the solution dries, it should not be harmful to pets aside from anything aquat...

No smell!!

[This review was collected as part of a promotion.] This truly was scent free! I was nervous to use in home with a kid, but it smells like nothing, even when originally sprayed. We get ants in spring and I’ve already seen a decrease in ants but time will tell if it eliminates them completely! The spray was super easy to use and it didn’t leave any residue on the floor when sprayed.

Keep this on hand this summer

[This review was collected as part of a promotion.] So spring is here and of course, bugs are wanting to come inside of the house. I like to spray around the vents and around the baseboards so that I can get the best coverage and the best performance out of it. I want to make sure that we are not experiencing creepy crawlers . I love that. It came with an extra spray bottle when the first one runs out.

Great sprayer and keeps the bugs out

[This review was collected as part of a promotion.] The Ortho Home Defense Max Indoor Insect Barrier works great. I love the easy to use sprayer. It dispenses the product well and I’m not constantly squeezing the trigger. I have sprayed it along the base boards to keep bugs out. There’s no lingering odors so it’s great to use indoors.

Great value duo

[This review was collected as part of a promotion.] I used the indoor insect spray today in corners of my kitchen as a defense for those pesky little ants and insects now that the weather is getting warmer. I have yet to see how well it works, but I’m excited. There is a strong odor but that’s expected with these sprays. But it was easy to use overall. I just be careful if you have kids or pets when using this product.

Jug leak

Results seen within hours! Excellent!!

Would Recommend

Purchased for our basement floor level apartment. We had an influx of earwigs after a large storm. I have never been so impressed by a pest control product in my entire life! After hooking up the convenient and straightforward to assemble sprayer wand, I was able to reach behind our kitchen appliances with ease. You can clearly see and hear when the product is coming out of the wand, and it dries within minutes! Our pets were unaffected, and there was no noticeable odor or fumes of any kind. Le...

Faulty Sprayer

Would Recommend

I have been a consistent consumer of Ortho Home Defense MAX for 20 years, however, the most recent 1 gallon container had a faulty sprayer which after trying everything doesn't spray unless holding the container on its side practically almost upside down which resulted in excess poison everywhere with majority of the liquid being leaked from container. I wasn't able to make a one pass barrier along my homes interior.

Don’t Buy

This product is a joke. It must be sugar water. I have to spray so much that the insect dies due to drowning. A can of starch is more helpful.

I am disappointed. Bought this to help with my silverfish problem. My husband sprayed this and the next day already saw two of them crawling even when we literally just steam and clean the floor.
