What are fleas?

Fleas are tiny wingless insects that feed on the blood of mammals and birds. The most common flea species that affect dogs and cats is the cat flea, Ctenocephalides felis. Fleas are external parasites, meaning they live on the outside of their host. They are typically 1-3 mm long and can jump long distances – up to 7 inches vertically and 13 inches horizontally. Fleas survive by feeding on blood – they don’t eat solid food. The flea life cycle has four stages – egg, larva, pupa and adult. Adult fleas mate and lay eggs on an animal host which fall off into the environment. Eggs hatch into larvae which feed on organic debris. Larvae pupate into cocoons and finally emerge as adults ready to find a host and feed.

Fleas can cause a number of problems. Their saliva contains proteins that can trigger severe itching and allergies in pets. Heavy infestations can cause anemia from blood loss. Fleas also transmit other parasites and diseases – in particular, the bacterium Bartonella henselae which causes Cat Scratch Fever in humans. Flea infestations in the home often lead to frustration and stress for pet parents having to deal with the effects on their animals and trying to eradicate the pests.

How do fleas spread between pets?

Fleas spread rapidly between pets through direct contact. When pets play, groom each other or snuggle up together, adult fleas can easily jump from one animal to another. Flea eggs fall off the pet’s coat during activities or sleep, allowing the eggs and larvae to accumulate in the home and environment. Puppies and kittens under 6 months old are very vulnerable as they have less developed immunity to fleas.

Indoor-only pets can pick up fleas from other pets during visits, like being boarded together or visiting the vet clinic. Outdoor pets are also exposed to wild animal fleas from sources like raccoons, opossums, foxes, and feral cats. The emergence of fleas is seasonal, with populations spiking during warm, humid weather in summer and fall.

How long can fleas live without a host?

Adult fleas can only survive for 1-2 weeks without a blood meal from a host. However they can live much longer in different life stages:

Flea eggs can survive for up to two weeks without hatching.
Larvae can survive inside cocoons as pupae for months – they’ve been known to overwinter in warm weather climates.
Adult fleas emerge when they detect the presence of a potential animal host through vibrations, carbon dioxide, heat and movement.

So while adult fleas die quickly unhosted, eggs and pupae can persist in the environment for long periods before developing into hungry new adults. This makes the flea life cycle very difficult to break and eradication challenging.

How do fleas get into homes?

Fleas enter homes in a few key ways:

On infested pets – adult fleas ride into the home and start the infestation.

From developing eggs and larvae – these can be carried inside on pet’s coat or feet and find ways to pupate in carpet, bedding etc.
Re-emerging adults – pupae already in the home surroundings detect host presence and become active.
Wild animal introductions – urban wildlife carry fleas inside.

Hitchhiking on human clothing and shoes – adult fleas grab onto people visiting other infested properties.

Once an infestation begins, flea eggs and larvae will rapidly accumulate in crevices, carpet, furniture and anywhere pets sleep or rest. The new adults hatch and start the cycle over again. Within 1-2 weeks, flea populations can explode leading to significant pest issues.

Where are fleas commonly found in the home?

Fleas thrive in areas where pets spend most of their time resting and sleeping. Key problem spots include:

Pet beds and bedding
Couches, chairs and human bedding – anywhere pets hang out
Carpets and rugs – flea eggs fall deep into fibers and accumulate

Cracks in hard floors
Under furniture cushions
Yards, patios and decks – anywhere pets or urban wildlife frequent

Vehicle interiors if pets ride along

Fleas prefer settled, undisturbed areas for larval development. Their small size enables them to fit into incredibly tight spaces away from regular cleaning. Once infested, these areas can sustain new generations of fleas over months or years.

How can you find fleas in the home?

Confirming the presence of fleas takes some detective work. The small size and quick movements make them hard to spot. Signs that fleas may be in a home include:

Itchy bites on pets – especially around the tail, groin, tummy and feet.
Allergy symptoms in pets like itching, scratching, licking, fur loss.
Flea dirt – tiny black specks of dried blood (flea feces).

Itchy bug bites on your ankles.
Constant reinfestation of pets no matter what treatments you’ve tried.

To check for fleas, run a fine-toothed comb through your pet’s fur over a white paper plate or sheet. The dark crawling insects or black specks of flea dirt will show up clearly against the white background. You can also check for larvae and pupae by vacuuming areas where pets hang out, then placing some of the debris in warm, humid water. Any larvae present will become active and float to the top within minutes. Confirming fleas are in the home is the first step towards treating the infestation.

How long does it take for fleas to infest a home?

A home can become infested with fleas within 2-3 weeks of pets or wildlife introducing them. Here is the typical timeline:

1-5 days – Adult fleas start laying 40-50 eggs per day on the host.
1-2 weeks – Eggs begin falling off into carpets, bedding etc. and hatching into larvae.

1-3 weeks – Larvae pupate into cocoons and emerge as adults looking for a host.
3 weeks – New generations of adult fleas feed and start laying more eggs, continuing the rapid cycle.

Within 21 days, just a few introduced fleas can multiply into a serious infestation generating hundreds to thousands of hungry new pests. The flea lifecycle allows populations to explode very quickly once established in a home.

How do I know if my home is infested with fleas?

Suspect a flea infestation if pets are constantly scratching, evidence of fleas or flea dirt is found on them, and bites appear on ankles. Definite signs include:

Seeing live adult fleas crawling through pet fur or bedding.
A large quantity of small black flea dirt specks in pet sleeping areas.

Pet hair loss and skin irritation, often around the tail, legs and abdomen.
Larvae swimming to the surface after combing pets over damp paper or flea combing rugs.
Getting bitten by fleas around the feet and ankles indicating rampant newly emerged adults.

You may need to closely inspect pets and their regular resting areas to spot the first signs of flea infestation. Seek immediate veterinary advice if pets have severe itching, skin irritation or anemia symptoms. Confirming and treating early is key to stopping population growth before the infestation escalates.

What diseases do fleas spread?

Fleas can transmit a range of viral, bacterial and protozoan diseases between infected pets and people:

Plague – Carried by rodent fleas, causes fever, chills, nausea in people.

Murine Typhus – Spread by rat fleas, fever, headache, rash.
Bartonellosis – Cat fleas spread Bartonella, causes fever, fatigue, swollen lymph nodes.
Mycoplasma haemofelis – Canine flea-borne bacteria induces anemia in dogs and cats.

Dipylidium caninum – Flea transmitted dog tapeworm can rarely infect humans.
Cat Scratch Fever – Bartonella henselae bacteria, swollen lymph nodes.

Fleas can pick up pathogens from wildlife reservoirs or infected pets and transmit them to others through their bites. Control fleas on pets and avoid exposure to flea-infested wildlife areas to lower infection risks. Promptly treat any sick pets or flea bite infections.

How to stop fleas from spreading to your home

Here are some key steps to prevent introducing and spreading a flea infestation in your home:

Treat all pets with vet-recommended flea control like oral/topical medications or flea collars.
Wash pet bedding regularly in hot soapy water to destroy flea life stages.

Vacuum thoroughly at least twice weekly – dispose vacuum bags outside immediately.
Bathe and groom pets regularly to reduce flea eggs and dirt accumulation.
Treat your home with insect growth regulators which prevent flea larvae maturing.

Use flea combs to monitor for and remove all life stages from pets.
Wash your clothes after contact with other infested animals or properties.
Keep pets out of wild or wooded areas which may harbor fleas.

Consistency and diligence are key – it only takes one pregnant flea to spawn a new infestation. Consult your veterinarian and pest control professional if you confirm fleas in your home.

How to get rid of fleas in the home

Eliminating a flea infestation requires attacking all life stages:

Treat all pets with an effective flea control product for at least 3 months.

Wash all pet bedding on the hottest setting then dry thoroughly.
Vacuum thoroughly focusing on cracks, crevices and pet areas.
Use a flea spray containing an insect growth regulator on floors, furniture and carpets.

Consider foggers or flea bombs for heavy infestations, especially if no pets are present.
Hire a professional exterminator to treat the property.
Maintain vigilance for at least one month to ensure fleas are gone.

Note – always read and follow flea product safety directions, especially if treating while pets are present. Consistency is vital to break the flea life cycle. It may take weeks to clear an established substantial infestation.

Natural ways to get rid of fleas

Some people prefer natural flea control options:

Diatomaceous earth – powder desiccates insects.

Salt – acts as a dehydrating abrasive against fleas.
White vinegar – helps repel and remove eggs from surfaces.
Lemon juice – citric acid kills adult fleas.

Herbal sprays – rosemary, peppermint, eucalyptus deter fleas.
Bathing pets – soaps with citrus oils help wash off fleas.
Flea combs – effective for removing all life stages from pets.

Test natural or homemade treatments on small areas first and supervise pets closely. Essential oils can be toxic to cats. Many natural remedies require repeated, thorough application to sustain flea control.

How do you keep fleas out of your home?

Preventing the introduction and spread of fleas is vital. Recommended tactics include:

Treat pets year-round with veterinarian-approved flea control like oral tablets or spot-ons.

Vacuum thoroughly and frequently – dispose of bags immediately after.
Wash all pet bedding and blankets weekly in hot, soapy water.
Bathe pets regularly, at least every 2-4 weeks during flea season.

Groom pets outdoors and check for any signs of fleas afterwards.
Limit access of pets to wooded, wild areas where wildlife may harbor fleas.
Inspect and treat pets promptly after contact with potentially infested animals.

Mow and clear vegetation around the home to reduce flea and wildlife habitats.

Consistency is key – be vigilant year round. It only takes one fertile flea to spawn a new infestation. Consult your veterinarian for advice on safe, effective flea prevention for your pets.

Conclusion

Fleas can rapidly infest homes and pets causing significant irritation and health risks. Stopping fleas from spreading requires diligence in treating pets, vigilantly monitoring for signs of infestation, and proactively sanitizing the home environment. Work closely with your veterinarian and pest control professional to implement effective flea prevention and control measures. Consistency is vital as the resilient flea life cycle allows populations to rebound quickly. With early intervention and sustained effort, you can get rid of fleas and keep them from returning to help pets and family live flea-free.
