Advantages
More than 130 types of bugs die on contact. The barrier stays active for up to 12 months and leaves no stains or smell behind. The only thing that changes at home is the bug count.
Works on Contact
A bug walks across the treated line and that’s the end of it. You don’t have to wait around and wonder if the spray worked. This insect barrier goes to work fast, taking out insects as soon as they touch the treated surface. Ants coming through a crack in the wall, roaches slipping under the door: neither gets a second try.
Year-Long Protection
Apply Ortho Home Defense Max once and the barrier keeps working for up to a full year. Forget respraying every few weeks or guessing whether it has worn off. The formula bonds to the surface and stays active through foot traffic, cleaning, and a change of seasons, so there’s very little upkeep on your side.
Indoors and Out
Plenty of bug sprays kill well but smell harsh enough that you don’t want them near your family. Ortho Home Defense Max avoids that trade-off. It dries clear, leaves no lingering smell, and doesn’t stain floors, baseboards, or walls. Use it indoors along baseboards and around windows and doors, or outdoors along the exterior perimeter of the house. Spray wherever bugs look for a way in.
Choose Your Home Defense
Some homes need an indoor barrier, others need coverage outside, and plenty need both. Choose the product that matches where the bugs are getting in.
BugClear: Outdoor Insect Killer Spray
This concentrated outdoor formula works down into the lawn and landscaping and kills mosquitoes, ants, spiders, fleas, ticks, and more than 100 other insects. The yard goes back to the people who actually use it.
Fire Ant Killer: Broadcast Granules for the Yard
Scatter the granules over the lawn and the fire ant mounds are gone in 15 minutes. A protective barrier stays behind and keeps the ants from returning for up to 6 months, across your entire yard.
Home Defense Insect Killer: Indoor and Perimeter Spray
Ready to use right out of the bottle, this spray lays down a continuous bug-killing barrier along the perimeter of the house and inside it. It goes after ants, cockroaches, spiders, and more, and the comfort wand keeps application quick and easy on the hands.
Home Defense MAX: Battery-Powered Indoor Insect Barrier
This battery-powered sprayer does the pumping for you. It comes ready to use straight out of the box, kills ants, roaches, spiders, fleas, and ticks, and puts down an even, consistent layer in every corner of the house.
Kitchen Insect Killer: Home Defense MAX Aerosol
An aerosol made for the spots where food gets prepared. It kills ants, roaches, and spiders on contact and sanitizes the surface in the same pass, so one treatment leaves the kitchen clean and free of bugs.
Cracks & Crevices Foam: Home Defense Insect Killer
The foam expands as it goes, pushing deep into cracks, crevices, and other hiding spots a regular spray can’t reach. It kills ants, cockroaches, fleas, centipedes, crickets, and more right where they nest, and the protection lasts long enough to close the problem off at the source.
GroundClear: Weed and Grass Killer With Comfort Wand
This weed and grass killer works down to the root and clears out dandelions, chickweed, crabgrass, moss, and more. The comfort wand makes patios, walkways, and landscaped beds quick to treat, and the formula is OMRI-listed, which matters if that’s something you look for.
GroundClear Year Long: Vegetation Killer Concentrate
One application clears the weeds and grass that are already there and stops new growth for up to a full year. It’s the pick for driveways, gravel paths, and any strip of ground where you don’t want anything growing.
GroundClear Super Concentrate: Weed and Grass Killer
This super-concentrated formula gets at the root of tough weeds like crabgrass, dandelion, and clover. A single bottle stretches a long way, so it’s a budget-friendly option when you have a large area to cover.
Features
A quick rundown of how the formula behaves: how fast it works, how long it holds, and where it’s safe to use.
Works Fast
Bugs start dying as soon as they touch the treated surface. No delay, and no waiting around for results.
No Stains, No Smell
It dries completely clear and leaves no smell behind, so you can spray along baseboards, window frames, and other indoor surfaces without mess or residue.
Interior and Exterior
Formulated to work on both sides of the house. Outdoors, spray a band along the foundation and around doors and windows to stop bugs before they get in. Indoors, treat entry points, baseboards, and corners where insects like to hide.
Review
Real homeowners, real houses. Here’s what they reported after using Ortho Home Defense Max at home.
About brand
Ortho has been around since 1907, and since 1999 it has belonged to Scotts Miracle-Gro, the company behind a long list of lawn and garden brands. Home Defense MAX takes on a very ordinary problem: bugs in the house that should have stayed outside. The line runs from indoor barriers to outdoor perimeter sprays, so you can build a full system around your home instead of relying on a single can. Whether you’re dealing with an active infestation or want to stay ahead of one, there’s a product in the range for that situation.
What separates it from an ordinary bug spray is how long it keeps working. Most sprays fade in a few weeks, and you end up going around the house again and again. Ortho Home Defense Max bonds to the surface and stays active for up to 12 months, so one careful application covers the whole season without guesswork.
The formula works on more than 130 types of insects, including ants, roaches, spiders, fleas, and ticks. It starts working on contact and keeps working after the spray dries, so bugs that cross the treated line don’t get far. Since it dries without odor or stains, kitchens, baseboards, and window frames are all fair game.
The idea behind the whole range is simple: keep bugs out of the house without complicated routines or a pest control appointment. Spraying takes a few minutes, and the barrier works around the clock after that.

Over the years I’ve gone through maybe five different bug sprays, and none of them lasted long enough to matter. I sprayed Ortho Home Defense MAX along the baseboards and around the doors in March. It’s August now and I still haven’t seen one ant in the house. That has never happened before.

In Texas you just live with bugs, or at least that’s what I thought. A neighbor told me about this spray, so I tried it. The roaches were gone in two days. I did the perimeter outside and haven’t had to go back to it. I wish I’d found it ten years ago.

With two kids and two dogs at home, I’m picky about what comes through the door. Ortho Home Defense MAX dries completely, with no smell and no residue, so I didn’t worry about using it around the house. And it works, which is what I cared about most. The bugs are gone.
FAQ
Home Defense MAX is a ready-to-use insect barrier. You spray it on the surfaces where bugs travel and it kills them on contact. It then bonds to the surface and stays active after it dries, so insects that cross the treated line later are killed too. It works on more than 130 types of insects, including ants, cockroaches, spiders, fleas, ticks, and centipedes. The label list also covers outdoor pests such as leaf footed bugs, stink bugs, and boxelder bugs, so check the label on your bottle for the full list.
It’s made for homeowners who want to stop ants, roaches, spiders, and similar pests, whether that means clearing out an active problem or building a barrier ahead of time. It works best on non-porous surfaces such as baseboards, tile, and concrete. Before you spray, read the label for the approved areas and the complete list of covered insects. Keep children and pets out of the room during application.
Hold the sprayer about 12 inches from the surface and apply a band about 4 inches wide indoors, or about 12 inches wide for an outdoor perimeter. Spray until the surface is slightly wet, not soaking. Work along baseboards, under sinks, around doors and windows, and along the foundation outside. You don’t have to leave the house. Just keep the area clear while you spray and give it time to dry, which usually takes about 30 minutes depending on ventilation. Bugs that touch the treated surface are killed on contact. With a full infestation, most homeowners notice a big drop in activity within a few days. Outdoors, plan to repeat the application about every 3 months for best results.
Once the spray dries completely, children and pets can be in the treated area again. While you’re spraying, keep them out of the room and let it air out before they come back. The formula dries clear, leaves no visible residue on baseboards, hardwood floors, tile, or painted walls, and has no lingering odor. The active ingredient is bifenthrin. The full ingredient list and safety data are on the product label and in the manufacturer’s safety data sheet.
Up to 12 months on non-porous surfaces like baseboards, tile, and concrete. The formula stays active through foot traffic, cleaning, and changing seasons. On porous surfaces or in busy areas results may vary, but most homeowners say they go several months at minimum without reapplying.
A regular bug spray kills what it hits and then breaks down, so you end up buying it and respraying again and again. Home Defense MAX keeps working long after it dries, for months and up to 12 months on non-porous surfaces, so the cost is spread over the whole year. It also replaces a lot of what people pay a pest control company for. For most common household bug problems you don’t need an exterminator. The formula is designed to deliver results comparable to professional treatments, and you apply it yourself in minutes, with no appointments and no service fees.
Both are ready-to-use Ortho sprays that kill bugs on contact and leave a barrier behind. Here is how Ortho Home Defense vs Max breaks down. The MAX version is labeled for 365 days of protection against ants, roaches, and spiders on non-porous surfaces indoors. It dries up to 30% faster than other Ortho formulas and leaves no stains or fumes. Its label also lists a wide range of insects, including fleas, ticks, scorpions, silverfish, and centipedes. If the standard formula already handles your bugs, there’s no rush to switch. If you want faster drying and the longer protection window, MAX is the one to pick. Ingredients and directions differ from bottle to bottle, so read the label on the one you’re buying.
