Unsure how I feel…
[This review was collected as part of a promotion.] Unsure how really feel about this product. We have an ant issue inside so I sprayed the area we thought they were coming from but they didn’t seem to die off…the spray nozzle is great. Coverage is great. But still using it to test out on other insects.

Good bye pesky bugs!
[This review was collected as part of a promotion.] I was very impressed with this product. I have not had any ants yet this year, so I am hoping this was my solution! There was no strong odor and the spray is easy to use. It dries quickly and my dogs didn’t seem to care I sprayed it.

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

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.
