Fleas 101: Where They Live, How To Get Rid Of Them and More

No one wants to deal with fleas, and it’s understandable. Fleas are a nuisance-type insect that find hosts to feed off of, causing irritation and itchiness from their bites and possibly spreading diseases like flea-borne typhus, plague, or cat scratch disease.

Beyond the fact that they’re a disgusting insect, how much do we really know about fleas? Where do fleas come from? What do fleas do to humans, dogs, cats, and other hosts? Can they live without a host and, if so, how long can a flea live without a host?

We wanted to provide a guide that tells you everything to know about fleas, where they live, how to get rid of them, and more!

Where do fleas live?

Geographically, fleas live just about anywhere in the United States. Fleas particularly enjoy hot, humid climates; so states like Florida, Alabama, or Louisiana will experience more fleas than some other places. Pest control experts located in high temperature regions will have to be aware that fleas live outside, and they prefer moist, shady, cool places like shrubs, bushes, leaves, and trees. In areas with cool, dry climates, such as Montana or Colorado, people will not see as many fleas.

Do fleas live in grass?

When treating a client’s property for fleas, it is important to know where these insects choose to hangout. Fleas do not fare well when they’re subjected to direct sunlight. For this reason, fleas choose to hide in lower areas of grass that are close to the soil. With that being said, a well-manicured lawn is a less likely spot to find fleas.

In taller grass, however, it’s possible that they might hang out in the darkness between grass blades. This is even more possible if the tall grass is beneath the shade of a large tree or another obstruction to sunlight. All in all, fleas prefer areas that are shady and moist. When treating a client’s property, be sure to target additional shaded areas where other animals may hide, such as underneath decks or porches, dog houses, crawl spaces, wood piles, etc.

How do fleas get inside?

While it is important to understand where fleas may be located outside, clients are more likely to be disturbed by fleas inside of their home. The real question is: how do fleas find their way indoors if clients are ensuring their homes are hermetically sealed? 

It is common knowledge that fleas are likely to make it inside the home via a host of some sort. Essentially, it’s unlikely they’ll crawl indoors by their own means, and instead prefer hitching a ride on a host like your client’s pets. Fleas are attracted to the carbon dioxide and body heat that most mammals release. While humans emit carbon dioxide and body heat, fleas prefer animals like dogs and cats because of their warm and fluffy fur.

How do fleas get on dogs?

If a client’s dog is in close proximity to fleas, they may become a target for these tiny insects. Fleas have the ability to jump onto dogs to start feasting on their blood, causing Fido to scratch frantically to cope with the intense itchy feeling that comes from their bites.

After being carried into the home via your client’s pet, they will find ways to nest into their furniture, and floor cracks until they leap again onto another host, whether that’s the client, their dog, or any other human or animal entering or leaving the building (including you and your employees). 

As a pest control expert, it is important to treat the inside and outside of your client’s home to effectively eliminate fleas. While you and your employees are most likely not pet experts, it is important to urge clients to ensure their pets are also getting the flea treatment they need to prevent spreading. This way, the client can better ensure the eradication of fleas even after your part of the job is done. 

Where do fleas come from if no pets?

It stands to reason, then, that you will never need to manage a flea infestation for a client if they don’t have a dog or outdoor cat. By the numbers, you’re probably right; it’s significantly less likely that fleas will find their way inside if there are no animals present.

However, it is still possible. Fleas can make their way onto other animals inhabiting the property such as:

  • Racoons 
  • Rats
  • Mice
  • Rabbits
  • Skunks

If any of these creatures are surrounding the client’s property, or even hiding out somewhere in the structure of the home or office (unbeknownst to the client), they can still spread fleas and create a problem inside the home.

How do you get rid of fleas?

So now you know everything you need to know about fleas, but you may still be pondering the best (and most effective) method to get rid of them.

If your company is in the pest control business and wants to ensure a flea-free environment for all clients struggling with an infestation, you need more than just an understanding of fleas.

You need solutions.

Luckily, Bask offers one of the best solutions out there in the form of the Mistmaster®, a revolutionary 3-in-1 compact misting system. The Mistmaster is a single solution that has the ability to replace the standard, malfunctioning equipment that your pest control company is used to operating. Plus, it doesn’t have any of the inherent problems associated with the standard pump sprayers and backpack sprayers that your company may currently be using!

 The Mistmaster, paired with the Bask recommended Zoecon Essentria IC3 Concentrate Insecticide treatment, can be applied to eliminate fleas using any of the three misting functions: 

  • Mist Bower
  • Misting Wand 
  • Misting Station operated by remote control

Whatever option works best for your operation, the Mistmaster will work!

Indoor treatment

As a licensed commercial pest control applicator, you will need to determine which pesticides are safe for indoor use to eliminate fleas. All you need is a great indoor-approved pesticide and your Bask Mistmaster and you’re good to go! Luckily, the Bask recommended Zoecon Essentria IC3 Concentrate Insecticide is safe to use indoors when treating a client’s property for fleas. 

The Mistmaster itself is safe to use inside because it is a battery powered machine that releases no gas emissions. The Mistmaster applies a uniform mist across all surfaces and in all areas. Its constant high pressure ensures no single area is oversaturated, but everything sprayed is evenly coated with treatment to disrupt the fleas life cycle and stop them dead. If you’re looking for a more precise solution, the Bask Misting Wand can be used to target small, hard-to-reach cracks and crevices around the client’s home. 

Outdoor treatment

Treating the outside of the home or office is almost equally as important, as the fleas have to come from somewhere!

The Bask Mistmaster makes it very easy to spray the grounds using the mist blower function, which is ideal for portable, widespread treatment of large areas. You also have the capability to create a permanent misting station grid for your client with our Mistmaster Overhead Kit and Ground Risers that will automatically apply pesticides via a click of a button on our long range remote control.

Not only can your pest control business utilize the Mistmaster as a piece of equipment to treat customers’ homes and properties, but your business can also install these misting systems into clients homes to create an additional form of income. 

Incorporating installation as an offering for your pest control business can create the following opportunities: 

  • Renting out the unit to clients/seasonal clients
  • Installing the misting stations and selling unit to client
  • Charging clients for refill of treatment solution in their installed unit
  • Developing a monthly service plan for clients using an installed unit

Overall, the Mistmaster is an extremely efficient solution for all of your pest control business needs. One piece of equipment creates a diverse offering for your business and will ensure the fleas invading your clients property are eliminated.


Aside from eliminating fleas with insecticide, it is important to keep the property sanitized to prevent fleas from reappearing. Luckily, you can also use sanitization treatments in the Mistmaster. Adding sanitization treatments to your offerings will create an additional stream of income for your pest control business. 

Simply flush the tank of the Mistmaster with water and load with the Bask recommended Husky 892 Concentrate Disinfectant to make sure the premises is clean, disinfected, and thoroughly sanitized. Keeping a clean environment helps discourage fleas from forming a haven later on.
