Immediate effect.
I live in a hot area and it is common to see bugs sneaking in when it gets hot. I sprayed this in my doorway and immediately started to find dead roaches and spiders not even a foot away from the area they usually come in at. It was gross and I’m so thankful I tried this.

Broken box and damaged items
Do not purchase items for a student from Target as Target will not replace the item of refund you for the item when it arrives completely smashed and broken due to their poor pacaking. (All items thrown loose into a 3 foot x 4 foot box) . Students away at college have no transportation, which is the reason for ordering household items online. Use another vendor or local store.

This stuff is great for when you suddenly have a million flies in the house. I spray it on the windows where they congregate and then I go around for the next couple days sweeping up dead flies off the sills.

Very effective and reasonably priced. Target sells this product for less than anyone else. Sprayer is sturdy and works every time. Good product and dispensing mechanism.

Kills all the bugs!
I use this both inside and outside my home, especially in the garage and it kills all the crazy Arizona bugs dead! Has a slight odor when wet then disappears when dry. Some bottles smell stronger than others. Seems to be effective for many months. I concentrate the majority of my spraying at my door thresholds so anything that tries to sneak in ends up dead. Make sure you don’t get it on your skin, it will definitely tingle and have a burning sensation. I wear gloves when I spray in case the nozzle leaks a little.

It works!
I sprayed this around the outside perimeter of my house and the next day, I found at least 7 spiders that had dropped dead. Over the next few days, more dead spiders kept showing up. It’s so good that I just bought another bottle.

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.

Not So Great
Did not work that great for me. It only works when you spary it directly on the bug.

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!
