No more camel crickets
Been using this for years around the out door perimeter and inside basement for camel crickets. It definitely works. People need to realize how it works- it works on the nervous system- it's not an instant thing, When the bugs or crickets walk on it, it gets on their legs. They groom themselves by licking their legs which has the chemical on them and that's how it's ingested. Give it a week- they need to walk thru and that is why it has to be sprayed on the perimeter. For people saying it's no good on spiders, daddy long legs aren't listed and they don't get affected the way the spiders listed do. Read the entire list- you'll see the big spiders that it works on. 'Daddy long legs are harmless, they catch little gnats and aren't interested in you and can't bite you, I'm glad this doesn't work on them- they're good to have around. Great value, does what it's supposed to. Once dried indoors - you're good to go. Spray on NON-POROUS SURFACES ONLY! Highly recommend!

Doesnt Work and Leaks Everywhere
Unfortunately the product arrived with what appears to be a defective trigger spray. When using and simply transporting, it leaks everywhere and gets on your hands and feet. With regards to performance of the liquid- I dont see much improvement. Overall I felt it was a wasteful purchase and poorly designed without safety features (like functional trigger) to ensure safe and even application.

Doesnt keep bugs away.
Definitely killed a spider when I sprayed it. But unfortunately did not keep them away. I sprayed it in every corner of my room and along the edges and I hear crickets now 😩 so definitely not a repellent. The smell isn’t heavy so that’s good when you wanna kill a bug.

We're sorry to read about your disappointment with Ortho Home Defense Max Indoor Insect Barrier and appreciate your feedback. It does take some time for the insecticide to affect the target insect. This does not have an ingredient that immediately immobilizes the insect upon contact. For harder-to-kill insects like cockroaches, it may take up to 6 days for them to die. If the barrier was removed (treated area scrubbed or mopped clean), you will need to reapply. You may need to reapply every 1-2 weeks until eggs/pupa have emerged and are in a "treatable" condition. We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply.

Ants still here
It gets two stars because it does kill on contact. But, it doesn't keep ants away. That was the reason for my purchase.

It does work to an extent
Does it kill bugs the second you spray them …yes. Does it create a barrier (like it’s advertised) to keep bugs away ….no.

Disappointing
The first iteration of this insect killer was amazing. This one is awful, disappointing and frankly frustrating if you actually need the spray to do its job. I’m so disappointed and I’ll certainly find a different bug barrier to use.

Lifesaver and doesn't stain
This has been my go-to bug spray since moving to a big city and dealing with more bugs in my apartments! I love this one because the scent is minimal, it works quickly (especially for getting the creepy crawlers on the ceiling!!), and maybe most importantly, does not stain any of the walls or surfaces I’ve sprayed it on!

Amazing!
I do not have a dislike. It’s fast working, doesn’t have a strong smell. It’s also long range so if you’re scared of bugs and insects like me, you can stand about 2 feet away and aim and it’ll still get the job done.

It Works; No More Bugs
I've only used this 'Ortho Home Defense MAX Indoor & Perimeter Insect Killer' once and it still worked the next day even after the solution dried up. I had an ant trail and a lot of flies in one of my rooms, so I sprayed this all over the ants and where the flies mainly stayed at. The next day, I saw a lot of flies drop dead mid-flying in the air. Also, there was no more ant trail. Yes, this works; and I highly recommend getting this product if you want to get rid of bugs and insects in your areas.

Its not MAX
Although the listing is for ortho home defense max, I received the regular home defense- you will be expecting a stronger product than what you get. Perhaps they are aware, perhaps they are not

My new holy grail product
I don’t write reviews often, but this product WORKS! I wish I found it sooner. Had some ants outside my front door that were finding their way into my kitchen, sprayed the outside and haven’t seen any more since. But I’ve also been seeing a lot of spiders around my place lately, so I sprayed a few of the spots where I see them frequently since I had spray leftover and in 2 days I’ve been finding a handful of dead spiders. Big ones. I’m ecstatic not to have them running around anymore! My previous apartment had a spider problem with black widows and other spiders coming inside and I tried everything, pest company came out and sprayed multiple times and nothing worked. I wish I would have found this months ago! It will be my go to from now on!
