Effective at keeping sugar ants away!
[This review was collected as part of a promotion.] Ortho Home Defense Insect Killer is one of my go-to products every spring when the sugar ants start coming inside looking for water and sweets. I sprayed the perimeter of my home along with common entry points and moisture areas like under sinks, around pipes, toilets, tubs, and windows. I noticed a significant reduction in ants coming inside, and the ones that were getting in did not stick around long. What I really appreciate is how effective and long-lasting it is. One application seems to continue working for weeks. I also have 3 dogs, 2 cats, and a child who is sensitive to products, so safety is important to me. I simply allow the treated areas to fully dry before letting everyone back into the spaces, and it has always been a no-brainer product for our household. If you are dealing with seasonal ants or other crawling bugs, this product absolutely gets the job done.

Easy to use
[This review was collected as part of a promotion.] This is such an easy product to use. No overwhelming odor or noticeable residue. The trigger sprayer makes it easy to pin point the exact areas you need and takes the pressure off your wrists and shoulders. It's helped eliminate our most common pest, ants.

Not that good
[This review was collected as part of a promotion.] It didn't really control bugs. I still have some ants . It only last a few hours . Disposal was ok. I feel that the formula could be better . Could be stronger

We're sorry to hear about your disappointment with Ortho Home Defense Insect Killer for Indoor & Perimeter and appreciate you taking the time to share your feedback. We want to make sure you get the best results, so here's a tip: This product does take some time to affect the target insect as it does not have an ingredient that immediately immobilizes the insect upon contact. For harder to kill insects like cockroaches, you will need to wait up to 6 days for them to die. This product may be applied every 1-2 weeks until all eggs/pupa have emerged and are in "treatable" condition. We want you to feel confident in our products. That's why we offer a product guarantee. If, for any reason, you're not satisfied with the results after using this product, you're entitled to get your money back. (Limitations apply). If you'd like to learn more, you can visit our Help Center at https://scottsmiraclegro.com/en-us/support/help-center/helpcenter and chat with us for additional assistance. We're here to help!

Thoughtfully designed and gets the job done
[This review was collected as part of a promotion.] I’ve been very happy with the Ortho Home defense insect kit for indoor and outdoor perimeter use this season. The bottle size is generous without being bulky and it stores easily when not in use. One of the standout features is the spray design itself. The grip fits comfortably in the hand and feels natural to use, which makes treating larger areas much easier. The spray function also works extremely well with impressive range and two useful settings. The mist option is great for covering broader outdoor areas like mulch beds while the targeted stream works perfectly for cracks in cement and tighter spaces around the home. The application feels controlled and efficient rather than messy or awkward. Most importantly, the product does exactly what it promises. It has kept both the inside and outside of my home insect free throughout this season, reliable easy to use and thoughtfully designed overall.

Easy to use
[This review was collected as part of a promotion.] We bought this product times before, without realizing that we did. I am not comfortable using it indoor so we kept it for outdoor only , since i don't want to get much chemicals inside. We don't have a lots of bugs inside after doing the spray 3 times a year so I guess it is really working very easy to use and following the instructions.

Works great! Lasts all year!
[This review was collected as part of a promotion.] This is a big gallon with an easy handle, easy instructions to set up hose and operate and control the amounts you spray. My mothers uses this at her house and so it was an easy yes trial for it. It dries fast, minimal smell and it goes a long way around house!

Great product!
[This review was collected as part of a promotion.] Love the packaging and the ease of use for this product. We are fighting sugar ants and it killed them immediately with no residue. It did not stop further intrusion though so multiple sprays are needed.

Easy to use
[This review was collected as part of a promotion.] Easy to use. Quick drying. Sprayed the perimeter of the house before spring to protect against ants coming in before the exterminator comes. Advertised as non toxic to kids and pets once dried.

[This review was collected as part of a promotion.] Coverage is amazing. Instructions are easy to read and understand. The results are out of this world. And the daily maintenance for my house is once a month I’ll do the perimeter of the outside of the house.

Great o Kill Bugs!
[This review was collected as part of a promotion.] Great packaging came fully wrapped I was concerned about the possibility of spilling but it was wrapped in plastic. I was so excited that this covered all of my 3,000 sq foot home inside and outside and I have plenty left over. I live in Texas so bugs are king here but I haven't seen any since spraying and it's getting warm out now. Excellent Product.

Bug killer ineffective
[This review was collected as part of a promotion.] This product was not that great. We live in the woods and wolf spiders and ants are all around. I did the directions as it said and it didn't seem to make a difference.

Kept the bugs away — get a new spray!
[This review was collected as part of a promotion.] No after smell, sprayed in corners around the garage which is where most bigs seem to come in from. The attached spray does not work, it leaks and doesn’t spray well, so I recommend putting it in a different spray bottle.

Not bad, not pet safe
[This review was collected as part of a promotion.] Not a bad product by any means but it’s not exactly people or animal safe! The recommendation is to clear the house or sprayed areas and then allow those areas to dry! Consider taking the family out for a trip to the park or something. I’m not mad at the packaging.
