How Long Do Adult Fleas Live

Let’s face it, there are many things in life that can be pretty creepy. Take fleas for example. It’s just unnatural for something that’s barely visible to bite you, and make your skin irritated. Insect bites are common, but insect saliva injected into your bloodstream as a result of a bite is even worse. With all these things said, we will try to answer the question How long do adult fleas live? You’re reading this article but don’t actually need to know how long adult fleas live, you already know that they live for approximately 2 to 4 months, you want to know what the best way is to get rid of them. There are many options available to rid your home of these tiny creatures but you’ll want to do a bit of research and find out which option will work best for your situation.

As pediatricians, we have often been asked about the life cycle of a flea, which has always seemed to us to be an odd question. After all, patients generally don’t have any interest in the adult life cycle of the flea; they are thinking about getting rid of their little pest, so that it cannot bite them and infect their children with whatever it is that fleas transmit to people (not Rickets or typhus anymore—those are passe).  We all know what fleas look like. They are small, pesky black insects with a little hump on their back that seems to make them jump higher than other jumping insects. Fleas may not seem to be dangerous, but they can be very damaging since they are vectors of many diseases that can cause illness in people and animals. Case in point, dog owners should be familiar with the fact that fleas can transmit tapeworms to their dogs.

Fleas are a parasite that feed on the blood of their host. A female flea may lay up to twenty eggs per day while they are attached to their host, which hatches in between 14-21 hours. The larvae then go through a larval stage, where they feed on dried blood and then fall off the host into the environment. Once the larvae have fallen off, they will pupate into an adult in 1-2 weeks. There are four stages of flea life cycle that are broken down into: egg, larval, pupal, and adult stages. It can take anywhere from 1 to 9 months for any one stage of this cycle to be completed. Pesky things, aren’t they? No matter how much we try and prevent them, there are always ways to get them into our homes. With pests, the situation is even more problematic — they can literally be feeding off of us while we’re locked up in our bedrooms! But before you begin panicking, I’m here to help. Before we can get to grips with flea life cycles and their bites, we need to understand the stages adult fleas live through and establish a species of flea.

How Long Do Adult Fleas Live

Adult fleas can live up to a year, but they don’t always. Adult fleas will die if they don’t find a host to feed on, which can happen when you treat your home and pets with flea medications. Adult fleas also tend to be more susceptible to cold weather than larval stages, so they may not survive the winter if they’re left outside in freezing temperatures.

Flea eggs are laid by adult female fleas and hatch into larvae after about two days. Larvae feed on organic matter in your pet’s fur and take about three weeks to mature into pupae. The pupae then hatch into more adult fleas that will start reproducing themselves again! Fleas are the bane of anyone’s existence. They are tiny, they move quickly, and they can be incredibly difficult to get rid of. But what most people don’t know is that adult fleas only live for about two months at the most.

Fleas generally live for about two months—and even less if you have been treating your home’s environment with a flea-killing product like Frontline Plus or Advantage. This means that if you start treating your home and your pet for fleas a couple weeks before summer starts, when the weather warms up and those pesky little insects get active again, you will be able to enjoy nearly three months of peace from those tiny bloodsuckers!

When you have a flea problem, you want to know how long it’s going to take for your home to be free from these pesky, biting creatures.

The answer depends on the type of flea you’re dealing with. The life cycle of a flea can take anywhere from two weeks up to a year or more, depending on conditions in your home and outside.

When it comes to adult fleas, they can live as long as ten months without feeding on blood. That’s right—they can survive without eating for a full year!

So how long do adult fleas live? As long as it takes for their food source to become available again. Adult fleas can live for up to 2 months, but once they start feeding, that time span is reduced to just a few days.

A flea’s lifespan depends on a number of factors, including the environment it lives in, how well its host takes care of itself, and whether or not it has any natural enemies. The type of environment also affects how long a flea can live—for instance, if the weather is too cold or too dry, fleas may die off before reaching adulthood.

Fleas are also sensitive to light and heat, so if you keep them in an area with little light or no air conditioning they will likely die off sooner than if they were kept in a darker area such as under furniture or behind drapes where there’s less light exposure.
