About Ortho

Who This Site Is For

There's a specific moment we're writing for: you flip on the kitchen light at night and see something scatter under the counter, or you notice a fire ant mound has appeared overnight near the mailbox. Ortho has spent decades building products for that exact moment. This site exists to help you figure out which one actually fits your situation, whether that's a single spray can for a pantry problem or bait stations meant to wipe out an entire colony over a week or two.

The Products

Ortho's lineup splits roughly into two philosophies: kill it now, or take out the colony behind it. Home Defense Max sprays and Ant Killer Powder fall into the first camp — fast contact kill, no fumes, no watering in, good for the ants and roaches you can actually see crossing a floor or countertop. The bait-based products, like the Indoor Ant Bait Stations and Orthene Ant Bait, play a longer game. Foraging ants carry bait back to the nest, and the whole colony, queen included, goes down within days rather than minutes. Outdoors, the Orthene Fire Ant Killer handles mounds directly, sprinkled on and left to work without mixing. Between these, the catalog covers ants, roaches, spiders, fleas, ticks, and fire ant mounds, indoors and out, for people who want either an immediate fix or a permanent one.

Our Approach

We read labels closely before we recommend anything. That means paying attention to which ant species a bait is actually effective against, how long a treatment is supposed to keep working, and whether a product needs to be watered in or reapplied. Ortho publishes specifics — 8 months of residual protection, 189 mounds per bottle, 24-hour colony kill — and we treat those numbers as the starting point for any comparison we write. No guessing, no filler language standing in for facts we don't have.

Why We Recommend Ortho

We keep coming back to Ortho because the product range actually matches how pest problems show up in real houses: sudden, specific, and rarely just one bug. If you're dealing with a trail of ants on the kitchen tile or a fire ant mound by the patio, browse our guides to find the Ortho product built for exactly that fight.
