Anywhere between one and twelve days after being laid, these eggs hatch into tiny larvae. The larvae stay hidden in carpets, floor cracks, and furniture. Normally, flea larvae mature in one to two weeks, but hot and dry weather can slow that down to about six months.
These insidious hitchhikers can feed within minutes of finding a host and can breed within 24 hours, laying up to 50 eggs a day in your home and yard. So, yes, one flea can—and often does—become a problem.
The process can take anywhere from two to three weeks to several months, depending on the conditions. Adult cat and dog fleas can live up to one year in ideal situations, but only about one to two weeks if no host is present. Female fleas lay eggs while attached to the host.
They are opportunistic and just need to feed on the blood of mammals, so they can easily transfer from pets and animals to people. A group of fleas can also breed fast and just a couple of fleas brought into your home via dog or cat can quickly become an infestation on the animal and then transfer to humans.
You might be asking yourself will fleas eventually go away? While some could last 2 – 3 weeks, they could also live for up to 12 months on the host it finds, so it is unlikely they will go away on their own. Fleas can also reproduce very quickly by laying eggs in carpet, bedding, or garden prolonging the infestation.
Flea larvae can remain dormant in your home for months, so new fleas may continue to emerge — even after treatment. These fleas will quickly die after hatching if you've treated your home and kept up with regular flea preventive for your pet, but it can take a while for all the existing fleas to hatch and be killed.
If you see just a few fleas on your dog, you may be tempted to think it's not a big deal. Although the random flea might show up if you've just taken your pup for a walk, more than one or two could be a sign of a problem. As few as 20 fleas might mean your pet is infested, while the most could be between 200 to 300.
Flea infestations usually begin by bringing a single flea into your home. Fleas can come inside on pets or on you. Infestations do not happen overnight. Usually they begin quietly and 6-8 weeks pass before you may ever notice a flea.
Fleas can easily go unnoticed by any pet owner and often go undetected in the home for as long as 4 months. This occurs because fleas are very small, quick insects that lay microscopic eggs that can live in hibernation in your home for over year.
Getting rid of fleas is a difficult process due to the long lifecycle of a flea. Moderate to severe infestations will take months to control and require a four-step process for complete elimination: Sanitation. Thoroughly clean areas where fleas frequently breed.
The most common way for fleas to get inside your home is on your pet. Fleas live outside, often clustered together in the tall grass. They are attracted to the body heat, carbon dioxide, and vibrations that mammals emit as they move around.
Fleas are bad for your house and your health
Fleas also sometimes carry diseases such as flea-borne spotted fever, plague, typhus, and cat scratch fever. While this is more likely to become a problem if you do have pets, fleas in a house without pets can cause serious problems for your family.
Can fleas live in your bedding? Fleas can live in beds for about one to two weeks, and they like to burrow under sheets. Fleas need blood to survive, though, so they won't stay in one place for too long if there is no food source.
Fleas like hiding in crevices. Their populations are more numerous in places where they can feed (like pet bedding and living rooms) and reproduce undisturbed (like lower-traffic areas or in carpeting). They also inhabit upholstery, furniture, and other common household furnishings, especially where they can stay warm.
Most fleas have four life stages: egg, larva, pupa (in a cocoon), and adult.
For every six fleas seen, there are 300 adult fleas actually present. If animals are not present, fleas will opt to hop onto humans. They thrive best in indoor climates. The presence of adult fleas is just the tip of the iceberg.
While adult fleas all suck blood from a cat or dog or other mammal, their larvae live and feed on organic debris in the host animal's environment. Flea larvae are blind. If you happen to see one flea, there may be more than 100 offspring or adults looming nearby in furniture, corners, cracks, carpet or on your pet.
Random Red Bumps on Your Skin
You will notice clusters of red bumps on your feet, ankle, and legs. If that ever happens to you, you might have pests on your couch or bed. If you notice there's a lot of red bumps on your skin, the flea infestation is beyond your control.
When it has a host, an adult flea can live about 100 days. But how long can they live without a host? Those fleas typically live only one to two weeks.
Answer: You should not have to wash any clothes that were in the closets and drawers. More information on treating for fleas in the home.
