Dealing with fleas is the worst. One minute your pet is scratching, and the next thing you know, they’re everywhere—your couch, your carpet, your bed. If you’ve been looking for safe, non-toxic solutions, you might’ve come across hypochlorous acid (HOCl). But can it actually get rid of fleas? Let’s break it down.
Can Hypochlorous Acid Kill Fleas?
Technically, yes—but don’t count on it as your main flea killer. HOCl can take out some adult fleas on contact, but it won’t do much against flea eggs or larvae, which are the real problem. If you want to get rid of fleas for good, you need a treatment that tackles the entire life cycle.
What About Flea Eggs and Larvae?
Flea eggs and larvae are tough little things. Even if HOCl kills a few adult fleas, it won’t stop the new ones from hatching and taking over again. For serious flea control, you’re better off using proven flea treatments like Frontline® Plus, Advantage® II, or Capstar® Fast-Acting Oral Flea Treatment.
Where Hypochlorous Acid Can Help
While HOCl won’t be your magic flea eraser, it can still play a role in your flea-fighting game. Fleas leave behind bacteria, allergens, and gross debris, and HOCl is a great way to clean up those messes safely. Use it to disinfect pet bedding, carpets, and furniture after you’ve tackled the infestation with stronger flea treatments.
The Best Way to Get Rid of Fleas
If you really want to wipe out fleas, here’s your battle plan:
Treat your pets – Talk to your vet about the best flea prevention. Bravecto®, Seresto® Flea Collars, and NexGard® Chewables are solid options.
Vacuum like crazy – Fleas love to hide in carpets, furniture, and even cracks in the floor. Vacuum every day and toss the bag or clean the canister immediately.
Wash everything – Pet bedding, blankets, and even your own sheets—throw them in hot water and dry on high heat to kill fleas at every stage.
Use an insect growth regulator (IGR) – Products like Martin’s IGR or Precor 2000 Plus Spray stop flea eggs from developing into biting adults.
The Bottom Line
Hypochlorous acid is awesome for cleaning, but if you’re dealing with a flea infestation, you need a more direct attack. Use vet-approved flea treatments, clean relentlessly, and bring in an IGR to stop the cycle. Then, you can use HOCl to keep your home fresh and free of bacteria left behind by fleas.
