About this product

Ortho Outdoor Insect Killer Concentrate is meant for mixing into a tank sprayer and applying wherever ants, spiders, fleas, or ticks are causing trouble. Once it's down, it sets up a barrier around the house that keeps working for months, not just days. It's rated for use on roses, vegetable gardens, and lawns, so one container handles a lot of ground.
