When Is One Flea A Problem?

Is One Flea A Problem

Let’s face it. Bug infestation always starts from one or a few bugs. 

These bugs enter homes, find their food sources, build their nests, and multiply. That’s the cycle that all bug infestation goes through.

At the early stage, it’s hard to spot an impending bug infestation, especially for tiny bugs like fleas, ants, and bed bugs.

Why?

They’re tiny and difficult to spot when their numbers are low.

You start to notice these bugs when their population in your home shoots up and when you start to get bites.

Unfortunately, that’s too late. 

But with fleas, things are a bit different. One flea can be a problem and can cause a bad flea infestation.

But it depends on where you saw the flea.

Below are the typical places where the sighting of a flea must ring your alarm bells and goad you to inspect your home and pets.

  1. Carpets and rugs
  2. Your bed
  3. Couch
  4. In your pet
  5. Hardwood floor 
  6. Furniture
  7. Pet’s bedding

So, another important question you might ask yourself is why one flea is a problem if you notice them in these places. 

How can one flea cause an infestation?

Let’s find it out.

How Can One Flea In Your Home Cause An Infestation?

Fleas are rarely solitary bugs. If there’s one flea in your home, then there are more. 

On top of that, if the one flea that you or your pet has brought inside the home is carrying eggs, then it’s only a matter of time that it’ll turn into an infestation. 

How?

Fleas multiply not as fast as other bugs do. But a single flea can be a cause of massive flea infestation in your home.

A single flea can lay 2000 eggs in her lifespan of 3 months. She’ll lay the eggs on your pet’s fur, in your beds, carpets, and other soft furnishings.

Fleas can also hide and lay eggs in the thin gaps and cracks on the furniture and hardwood floors.

The flea eggs hatch in one to ten days based on the humidity levels. The more humid your home is, the faster the eggs will hatch.

The larvae from the flea eggs will take two to three (and in certain cases, a month or more) to turn into adult fleas.

Before turning into an adult flea, the flea larvae build a cocoon to lock themselves. The cocoon is known as the pupae stage in the flea lifecycle. 

Adult fleas’ first job is to look for a host to get their blood meals. It’s critical for their survival, and fleas need it to mate.

After their first blood meal, fleas mate, and the female flea starts laying eggs within 24 to 48 hours of consuming the blood.

And the cycle continues.

So, what should you do if you see a flea in your home?

Let’s find it out.

Preventive Flea Control Methods On Finding One Flea In Your Home

It all depends on where you saw the flea. There are certain places where the sighting of a flea shouldn’t be a cause of concern.

You’ll find it out later in a minute. 

But before that, let’s assume that you found a flea on the places where it can be a problem, like beds, furniture, on your pet, etc.

In that case, here are the seven steps you need to follow –

Step#1 – Inspect Your Home To Find Out More Fleas

On finding a flea in your home, your first step is ascertaining if it’s an infestation. 

And you do it by checking in places and the nearby places for signs of fleas.

These signs can be –

  1. Adult fleas
  2. Flea feces
  3. Flea eggs
  4. Flea shells
  5. Flea nymphs

These signs won’t be there if there’s a solitary flea in your home. However, it always makes sense to look for them. 

Inspect soft furnishings like the bed mattress, couch, carpet, and pet bed for fleas and flea signs.

Then look for flea signs on the bed’s headboard too. Fleas will hide in the cracks and gaps on the headboard.

Don’t overlook your furniture and hardwood floor. Fleas latching onto pets will fall off their bodies and hide in the cracks in these places.

Step#2 – Inspect Your Dog To Check If There Are Any Fleas 

Unfortunately, your pets, especially dogs, bring fleas home. And one of the most common fleas in homes is dog fleas.

They get fleas by playing outdoors or from other pets or animals they encounter.

Check your dog’s fur for fleas. Fleas will hide deep in the fur near the skin. 

You must inspect your pet dog for fleas, especially when you’ve noticed your dog scratching often.

Use a flea comb on your pet to check thoroughly for the presence of any flea infestation. And bathe your pet with a flea shampoo.

If your dog or pet has fleas, you’ll find flea eggs, flea dirt (which are flea feces), and live fleas on your dog’s skin.

Fleas In Dog

In that case, take your dog to the veterinarian. 

Fleas are harmful to pets. They cause not only blood deficits in pets but also tapeworms.

So, do not skip this step. 

The flea treatment for your pet can be in the form of a flea collar, pills, and sprays.

If fleas have made your pet weak, then your pet might need dips too.

Your dog with a flea infection can transfer fleas to your bed too. 

Fleas and flea eggs will fall off your pet’s body and land on your bed, couch, carpet, and rug.

It’s only a matter of time before these flea eggs hatch and cause fleas in your home. 

Fleas in your bed will bite you for their blood meals in the absence of their host animal.

Step#3 – Do A Thorough Cleaning To Remove Possible Hiding Fleas

After following the first two steps, you must clean your home, especially your bed and other soft furnishings.

A vacuum cleaner is a default choice for many people. Some even recommend using flea traps.

But we highly recommend using a steam cleaner on soft furnishings and floor to remove any hiding fleas.

Steam cleaner produces heat to the level of 130F. Adult fleas can’t sustain this much heat.

And it also destroys the flea nymphs, flea eggs, and flea pupae. 

So, use the steam cleaner to clean your bed mattress, pillows, carpets, rugs, curtains, couch, pet bed, and other cushioned furniture.

Ensure that you clean the seams, folding, threading, and edges of the bed. These are the places where flea eggs stick and the flea nymphs hide. 

Also, wash the bed linen, pillow covers, and bedsheets in hot water. Hot water kills adult fleas and destroys the flea eggs.

Step#4 – Use Diatomaceous Earth On Hardwood Floor And Furniture To Remove Any Hidden Fleas

Many home products kill fleas. Diatomaceous earth is one of them. 

The fourth step is applicable if your pet is carrying fleas.

However, you can also do it by spotting a single flea on floor furnishings like carpet and rugs. 

It’ll ensure you’re not leaving anything to chance and taking steps to remove any fleas hiding in the hardwood floor and furniture.

Clean the carpet (or rug) with the help of a steam cleaner. 

(If your carpet is made of expensive fabric like leather, fur, or silk, it’ll be best to hand it over for a professional cleaning.)

Flip over the carpet and use the steam cleaner to clean the carpet’s undersides.

Ensure that you cover the edges of the carpet and rugs. The seams on the edges are where these tiny biting fleas hide.

Remove the carpet from the floor. And scatter diatomaceous earth on the hardwood floor, baseboards, and furniture.

Let the diatomaceous earth sit for a while on the floor for at least 30 minutes.

Diatomaceous earth contains diatoms which are fossils of planktons. They’re sharp.

These diatoms penetrate the bodies of the bugs and absorb the oily fats locked inside their bodies.

That causes the bugs’ exoskeletons to collapse. And the bugs die.

After 30 minutes, use a vacuum cleaner to clean the floor and furniture. It’ll remove any hiding fleas that must have died because of the diatomaceous earth.

After cleaning, dispose of the vacuum dust bag outside of the property.

Step#5 – Treat Your Yard For Fleas

You must keep your yard and garden trimmed and clean during the spring and summer.

These are the periods when fleas, ticks, and other tiny biting bugs that hide in grasses and shrubs waiting for a host are active.

Ensure that your grass lawn is perfectly manicured and there are no overgrown bushes and shrubs along your home’s perimeter.

Also, fleas thrive in humidity. And the damper your yard is, the better it is for fleas.

To control the dampness levels of your yard, don’t overwater your yard’s soil. And don’t let things, like old tires, containers, and pots, hold stagnant water.

Fix any leaking pipes in your yard causing the dampness to spike up. 

Remove organic debris like foliage and rotting wood pieces. These attract many bugs. 

And do not let waste pile up in your yard. So, ensure that you regularly dispose of waste from your yard’s trash bins.

You can also use flea sprays in your yard if the flea infestation in your home is heavy. 

Scattering insect growth regulators or IGRs in your yard is also great for controlling pests like fleas, ants, and termites. 

But you might need to do it if you don’t find more fleas in your home. 

When Is One Flea NOT A Problem?

Fleas come from the outdoors. They hide in the tall grasses, dense bushes, and shrubs growing in the damp areas.

Fleas wait in this dense vegetation for a host like your pet, any furry animal, and for rodents like mice, rats, and squirrels to latch onto.

Fleas can also latch onto your clothes if you walk through these places.

If you come back from outdoor activity and notice fleas or one flea latching onto your pants, socks, and luggage, then there’s no reason to panic. 

All you’ve to do is to use a flea spray on the flea. It’ll do the job.

But there’s a catch. 

You should and must always check your clothing and luggage for any bugs. It’s not only fleas that can latch onto these things but also bugs like ticks. 

The best approach is to use bug spray on your luggage before you take them inside. 

And putting the clothes straight into the washing machine and washing them with warm water.

Ensure you don’t keep your clothes on couches, beds, or dresser drawers.

That’ll cause the fleas and other bugs to hide in these places and multiply. 

It’s always best to put the clothes and other fabric in your washing machine and wash them with hot water.

Do You Need A Pest Controller If You Saw One Flea In Your Home?

You should hire a pest controller if you’ve found multiple fleas in your home after the inspection.

Multiple fleas in different areas of your home are an infestation. And most DIY ways to get rid of tiny biting bugs like fleas are not thorough. 

Conclusion

Is one flea a problem? Yes, it is. And that one flea can cause an infestation in your home.

It all depends on where you saw the flea. And if it’s inside your home, in specific areas, you must follow the steps to prevent flea infestation. 

Pets, especially dogs, can bring fleas home. And they can even transfer the fleas to your bed, which will lead to flea bites on your body.

So, look for fleas in your pet if you notice one or multiple fleas in your home.
