2020’s 8 Best Flea Sprays for Dogs

Best Flea Sprays for Dogs

When my friend’s dog got fleas recently, it broke my heart.

He’s a laid-back and quiet dog, but the constant itching made him pace and whine.

She hadn’t experienced having a dog with fleas before, even though he was a few years old. 

My friend wanted to give him some immediate relief, so we began to research. Besides the traditional flea pill, what were her dog’s options?

She couldn’t afford to take him to the vet and didn’t trust a collar to take care of the fleas very quickly. 

Turns out, tons of people use flea sprays for treatment and preventative flea care.

Check out everything I’ve learned and which flea sprays may be the best option for your dog.

How Do Flea Sprays Work?

All flea sprays have one main active ingredient that affects fleas the most.

Typically, this ingredient is a neurotoxin that first disrupts the flea’s nervous system[5], which is what ultimately kills them. 

The main ingredient may also be the part of the formula that attaches to eggs and larvae to prevent development.

How to Use Flea Sprays

It’s always a smart idea to read the instructions on a flea spray bottle before using it.

Some may require you to spray outdoor surfaces from a certain distance away to prevent inhalation.

Other sprays might need to be sprayed onto your hands and rubbed onto your pet, or be given time to dry before you use the furniture.

Since there are so many ways to use flea sprays, operate each bottle according to its specific instructions.

What to Look for in a Flea Spray

What you want to look for in a flea spray will be different depending on your circumstance.

What to look for flea spray works on dogs pets carpet furniture upholstery bedding thread fabric

Fleas love to hide in your dog’s bedding so you may need a product that can work on fiber, not just fur

Consider the following to help narrow down what to look for:

  • Will you spray indoors, outdoors, or directly on your dog?
  • Will you spray around kids, puppies, or cats?
  • Do you prefer all-natural ingredients?
  • Does your dog need tick protection as well?
  • Will you be spraying carpets or upholstery?

Once you know how you want to use the spray, you’ll know what to look for.


My friend ended up buying a flea spray that helped her dog and worked on all the surfaces of her apartment.

Her place was flea-free in just an hour after spraying, so sprays are definitely worth trying out if you haven’t used one before. 

Think about what you want most out of the flea spray to narrow down your options and you’ll find the right one for your dog and your home.


What Kills Fleas Better: Sprays or Dawn Dish Soap?

Dawn dish soap does kill fleas, but it’s a powerful soap formula that’s meant to strip dishes of grease and oil.

It will dry out your dog’s coat and may cause skin irritation, which is why it’s recommended for dog owners to only use pet products, like flea sprays, on their dog.

How Long Does it Take for Flea Sprays to Work?

Flea sprays start working as soon as you use them, but most need to be sprayed twice to completely take care of fleas.

The first spray treatment kills the majority of the fleas and the second round will kill and fleas, eggs, and larvae it missed the first time.

How Often Do I Need to Spray for Fleas?

After a flea infestation, you should do a minimum of two applications on your home’s carpets and upholstery to kill anything left inside.

You should also treat your yard and check the bottle you use to find out how long the spray will last for and when you should spray your home again.

Can Fleas Live in Bedding?

Fleas want to live on or close to the host dog.

They won’t stick around in bedding unless your dog is on your bed all the time.

A quick wash of bedding and sheets will take care of the fleas if you’re concerned that they’re living in your bed.

How Long Can Fleas Live in Your House?

When fleas have a host, they can live two to three months in a house.

If they’re stranded in your home without access to an un-sprayed dog, they can lie dormant for up to 155 days[6]
