Getting rid of fleas is a difficult process due to the long lifecycle of a flea. Moderate to severe
Flea eggs fall off their hosts, leading them to get stuck in carpets, in cracks and crevices, in pet beds and under furniture. This is why repeated vacuuming and cleaning your floors is necessary when getting rid of fleas in your home — especially in areas where your dog hangs out a lot.
What to do for heavy flea infestations. For heavy flea infestations, it's best to destroy and discard all pet bedding. For mild or light infestations, washing the bedding thoroughly in hot, soapy water is necessary for killing fleas and destroying their eggs and larvae.
Step 3: Disinfect the house
In most cases, it takes three to four months to completely get rid of a flea infestation since it takes fleas this long to go through their life stages, according to the American Kennel Club.
If you want ways to kill fleas naturally, salt and baking soda can dehydrate the fleas' bodies, killing them within a day or two. The bugs are also sensitive to high heat and soap, making steam cleaners, hot water and detergent, and hot cycles in the laundry extremely effective at killing 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.
Fleas have a complex life cycle. At some stages of their life cycle they are resistant to insecticides and other flea control products. In order to get rid of fleas in all stages of the life cycle, two or more follow-up treatments within 5-10 days after the first application are needed.
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 your dog is constantly being reinfested with fleas after treatment, it is most likely there is an environmental infestation in or around your house. The adult fleas we see on pets represent only 5% of the total population. The other 95% are immature stages in the environment.
It's not uncommon for a flea problem to seem worse before it gets better, and this could be related to numbers of new adults hatching out. So, if you're still seeing adult fleas, or you're being bitten, don't panic!
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.
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.
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.
For months, unseen young stages will continue to mature and emerge as adults. If a new female fleas finds an untreated animal, she'll take a blood meal, mate, and lay eggs within 1-2 days. Each female produces around 25 eggs a day. Thus, re-infestation can occur quickly.
Fleas can live on hardwood floors. They develop in cracks and crevices, which create a suitable micro-habitat for larvae. Tile floors are a poor habitat. Linoleum is even worse for supporting fleas, due to the lack of cracks.
They can also plague you, your spouse, and your kids with itchy bites, or make you sick. The most common disease fleas spread to humans is Murine typhus, which comes with symptoms such as rash, body aches, fever, loss of appetite, chills, couching, stomach pain, nausea, and vomiting.
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.
The flea life cycle, from egg to to adult, completes in 17 to 26 days in homes. However, after treatment, people will often continue seeing fleas for around 8 weeks. This is because after pupating, cocooned adults can stay quiescent (dormant-like) for up to 5 months while they wait to detect a host (heat and pressure).
It can take up to 3 months to break a total flea life cycle by using monthly flea treatments. For indoor flea control, vacuuming all floors, carpets, baseboards, pet bedding and furniture will help remove adult fleas and eggs.
Firstly, don't panic. Yes it's horrible that you've found fleas, but rest assured, most pet owners have had to deal with a flea problem at some point! Fleas are tiny, smaller than a pin head, but can jump up to a metre, and are so fast, you often don't see them even when they are in your house or on your pet.
Most successful flea treatment programs require at least 2-3 treatments at 14-day intervals using both an insecticide for the adult fleas and an Insect Growth Regulator (IGR) to prevent immature stages of fleas from developing into breeding adults.
