Not working. First time i sprayed it around my room which is very small it killed small bugs but after week later i see millipede crawling around my room again. you may spray it every couple day so 12 months of effect is just a lie.
We do apologize that you did not get the expected performance from Ortho Home Defense MAX Insect Killer for Indoor and Perimeter. Once an area or insect has been sprayed, it will take some time for the insecticide to be effective as it will not immediately control the insect. For harder to kill insects, like cockroaches, it may take up to 6 days to be effective. We want you to be confident in our products, this is why we offer a product guarantee. If you are not satisfied and would like to further discuss this, please contact us at 888-270-3714.
We are sorry to hear of your experience with our product. 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. We do have a product guarantee.
