Keeping pests out of your home is important — but so is protecting your furry friends. One of the most commonly asked questions among pet parents is:
“Is Ortho Home Defense safe for pets like dogs, cats, or other animals?”
In this comprehensive guide, we’ll explore the safety of Ortho Home Defense, how to use it responsibly around pets, and what alternatives you might consider if you’re concerned.
What Is Ortho Home Defense?
Ortho Home Defense is a popular insecticide spray used to eliminate and prevent pests such as:
-
Ants
-
Roaches
-
Spiders
-
Centipedes
It’s formulated for both indoor and perimeter use, making it a go-to solution for homeowners dealing with persistent bugs.
Is Ortho Home Defense Safe for Pets?
Yes — but only when used correctly.
Ortho Home Defense is generally considered safe for pets like dogs and cats once it has dried completely. The active ingredients — such as bifenthrin and zeta-cypermethrin — can be toxic if pets are exposed to them while still wet.
Key Rule: Do not allow pets into treated areas until the product is fully dry.
How to Use Ortho Home Defense Safely Around Pets
To keep your pets safe, follow these best practices:
1. Remove Pets Before Spraying
-
Move your dogs, cats, birds, and small mammals out of the room.
-
Cover aquariums and turn off air pumps to avoid chemical exposure.
2. Follow the Label Instructions
-
Only apply the product to areas recommended by Ortho.
-
Avoid spraying pet bedding, toys, food bowls, or sleeping areas.
3. Allow Full Drying Time
-
Typically takes 2–4 hours to dry depending on ventilation and surface type.
-
Ensure the area is well-ventilated to speed up drying.
4. Clean Up Any Excess
-
If you accidentally over-spray, wipe it away with a damp cloth and dispose of it safely.
What If My Pet Walks on It Before It Dries?
If your pet comes into contact with wet Ortho spray:
-
Wipe their paws or fur immediately with a damp cloth.

Watch for symptoms like:
-
Excessive drooling

Vomiting

Skin irritation

-
Contact your vet immediately if you notice any unusual behavior.
