Doesnt Work For 12 Months
The sprayer works really well. It doesn’t leak or drip like some of the other brands we’ve used. However, the pesticide itself has not been sufficient. It does not work for 12 months after use. It barely keeps insects at bay for 2 months. Won’t buy again.

Thank you for your feedback about the Ortho HD Core Insect Killer2 RTU. We appreciate you taking the time to share your thoughts! This product is only labeled for the control of those insects listed on the label. It does take time for the insecticide to affect the target insect, as it does not have any 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. 12 month control applies to indoor control of ants, crickets, spiders (excluding black widow and brown recluse spiders), carpet beetles, earwigs, firebrats, moths, and silverfish. This control is achieved whent the product is applied to non-porous surfaces. It may be necessary to reapply the product every 1 to 2 weeks until eggs/pupa have emerged and are in a treatable condition. If there is anything we can do to help you have a great experience, please contact our Consumer Services team at 866-324-9192 for assistance. We're here to help make sure you love your lawn!

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.

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.

Effective
[This review was collected as part of a promotion.] Ortho Home Defense spray came in so handy when I recently had an ant infestation in my home. Ants were all over the table. We found the source and sprayed it. Have not seen an ant since.

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.

Performance

Makes a big difference!
[This review was collected as part of a promotion.] We usually get summer ants that find their way into the house. We sprayed this and it made a BIG difference. We haven’t seen a single one. It was effective and easy to use and simple packaging and instructions. I would recipe d this product if you have any sort of exterior/interior insect problem!

Ant killer
[This review was collected as part of a promotion.] We started having ants in our house. I sprayed the areas with the ants and boom they’re gone. I recommend this as a preventative and treatment for ants in your house.

Safe to “Bug Off”
[This review was collected as part of a promotion.] Living in Texas, it’s a must to have good Bug Protection, especially as temps get warmer. I love that this Ortho Perimeter & Indoor spray is clear, odorless & has this Invisa-Shield technology that’s safe for households with children & pets after the spray has quickly dried. It’s easy to apply with the attached Trigger sprayer that allows the liquid to come out precisely & with just the right amount of volume. I especially use it around doorways & under kitchen & bathroom sink areas. Best of all, this bug defense lasts up to 12 months & is powerful enough to kill even the toughest, home evading insects! It’s simple to use & the Ortho Brand is one that I trust.

Good not great
[This review was collected as part of a promotion.] After using the product for about a month I realized that it does work. Does it perform as stated, not really. There are no smells or lasting odors and I really like the trigger to get into tight spaces. I've tried it both inside and outside of my home, but I still notice some little critters. Overall, I'd rate this as an ok product.

This is my favorite indoor insect killer. Will be
[This review was collected as part of a promotion.] Packaging is great. The trigger sprayer is amazing. I used the whole bottle around my house and haven’t really seen any insects inside. There is no residue left behind. I have a toddler so she knows not to put her hands where I spray but if you do have a baby, I would make sure that they didn’t get into it. I’m hoping this will last the full 12 months that it says, but if not I will buy more of this brand. I think it works really well.
