We're sorry to read about your disappointment with Ortho Home Defense Insect Killer for Indoor & Perimeter2 Ready-to-Use and appreciate your feedback.Timing is an important factor in insect control. Most insects cannot be controlled in the egg stage, so insecticides are targeted to control insects in the larval or adult stages. Also, more mature or larger insects will take longer to control than younger or smaller insects. You may not see the insects die immediately, but you should see a reduction in the pests or their damage within a few days. Treating both the outside entry points and the inside at the same time will also help.We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers.
