As few as 20 fleas might mean your pet is infested, while the most could be between 200 to 300. Ignoring a few fleas can quickly lead to an
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.
But are they really a problem? Most of the time, fleas are merely an irritant – their bites cause itching, but no more. However, the immune systems of many dogs and cats (as many as 40% according to some studies) see flea saliva as a dangerous foreign invader, and mount some degree of response to it.
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.
It can take up to 3 months to fully resolve a flea infestation (or even longer in some cases) - see “What is the best way to resolve a home infestation?” for advice on eradicating a flea problem as quickly as possible.
Put on knee-high (or at least calf-high) white socks and walk around your home for an afternoon, keeping close to carpeting and putting your feet up on furniture. Then, check the socks for fleas. If they've taken up residence in your home, odds are that a few will be visible on your socks.
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.
I've Got Fleas – Won't They Just Go Away? Unfortunately, no, they won't. Most fleas can live for between two and three weeks on a host organism, but some flea eggs can survive unhatched for up to an entire year. So even if the fleas you have are dying off, there will be plenty of eggs left to replace them.
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.
As few as 20 fleas might mean your pet is infested, while the most could be between 200 to 300. Ignoring a few fleas can quickly lead to an infestation on your dog and in your home,2 because two adult fleas could lead to hundreds of eggs and pupae. Fleas start feeding on blood within minutes of landing on your pet.
Their bodies can handle a lot of pressure to help them stay alive against mashing, scratching, or squeezing them in your fingers. Squeezing them in your fingers is nearly impossible. Even though it may seem impossible to kill them with your fingers, there is one way to kill them.
In just 30 days, 10 female fleas can multiply to over a quarter million new fleas in different life stages. Female fleas start producing eggs within 24 to 48 hours after taking their first blood meal and can lay up to 50 eggs per day. Optimum conditions for flea larvae are 65-80 ºF with shaded areas and high humidity.
In a word, yes. Fleas are tiny insects, so if your pet is carrying a single flea, it's highly improbable that you will happen to spot it – which means if you see one, it's extremely likely that there are more with it.
So, yes, one flea can—and often does—become a problem. Flea eggs usually fall off your pet and land anywhere your pet spends time: carpets, furniture and in bedding. If your pet sleeps with you, fleas could end up on your bed as well. In only a few days, these eggs hatch.
Depending on the level of infestation, it can take anywhere from a few hours to an entire day to clean your home. And you'll need to keep up this routine for at least two weeks or up to a month—and possibly keep using insecticides for a year to prevent fleas' return.
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. The entire lifespan of a flea, from egg to adulthood, can last a few weeks or even a few months.
Though they often burrow under comforters and sheets, fleas don't typically dwell in beds long term because they can only live without blood for about one or two weeks. Still, you'll want to look out for the signs so you can eliminate them as quickly as possible.
Vacuuming does work, at least in terms of reducing the severity of the infestation. But fleas breed quickly, and in the case of severe flea infestations it's unlikely you'll be able to remove all of the fleas from the carpet. In addition, flea eggs are sticky and attach themselves to carpet fibers.
Fleas go through a life cycle of egg, larvae, pupae and adult. Most flea treatments just kill adult fleas, but fleas can continue to emerge for months after you think an infestation has ended. When a newly emerged female flea finds a host, she can lay eggs within one day.
These pests are very hard to get rid of. Fleas have flattened bodies so they can move through the fur of their hosts easily. They also have very strong exoskeletons, making them very hard to crush. They also leap out of danger quickly and are very small, so if they do get away they are hard to find again.
Get Steamy. Once you have vacuumed your floors and upholstery, consider using a steamer or washing coverings in hot water. The heat will kill any additional fleas that may have been left behind. Other surfaces such as countertops and tables can also be cleaned with hot water.
A recommended chemical product to control fleas on pets would be Petcor and Martin's Prefurred. Petcor 2 Flea and Tick Spray is a pyrethroid-based chemical product that has an IGR (Insect Growth Regulator) that will kill the undeveloped stages of fleas (eggs, larval, and pupal) for a month on cats or dogs.
