Undisturbed and without a blood meal, a flea can live more than 100 days. On average, they live two to three months. Female fleas cannot lay eggs until after their first blood meal and begin to lay eggs within 36-48 hours after that meal.
Fleas lay eggs at night, so it's common to find their tiny, white eggs in bedding. As these eggs hatch, the worm-like larvae will emerge and hide in their bed too.
Circadian Rhythm of Fleas
Cat fleas don't sleep, but they do have circadian rhythms of activity and rest. They're more active at night than in the daytime. Consequently, flea traps are most effective at night.
Adult fleas will not emerge from the cocoon until there is a clear presence of a host, such as movement or body heat, which will signal that there is a blood meal readily available. Adult females begin to feed from a host within a few hours of emerging from the cocoon and soon after will mate and begin laying eggs.
Fleas are most active around sunset, and least active at sunrise. At dusk, there's an increase in movement, egg production, and respiration. Fleas are never completely inactive. They produce eggs and feces through all hours of the day.
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.
At What Temperature and How Quickly Do Fleas Die? Adult fleas die at temperatures colder than 46.4°F (8°C) and hotter than 95°F (35°C). Immature fleas, which refers to both flea eggs and larvae, are slightly more susceptible to the cold, dying at temperatures below 55.4°F (13°C).
Mopping and steam cleaning can help to kill flea eggs, and washing linens, bedding, and pet beds in the washing machine on the hot cycle is also advisable. If possible, declutter your home so it's easier to clean and there are fewer places for flea eggs to hide.
Look Over Carpeting
Capreting, area rugs and throw rugs are common places for fleas to lay eggs, so run your hands over these spaces carefully, looking in between the fibers for eggs. Again, unless you have dark carpeting, they can be tough to spot, so look thoroughly with the aid of a magnifying glass.
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.
They are oval in shape and of a whitish colour. Under a microscope, one can see that flea eggs look like rice grains. Over time, their appearance may change, in terms of colour. From shiny and almost translucent they can become bright and solid white.
Flea season can last anywhere from 6-9 months to all year round in some states. Fleas love warm temperatures, so your season can start early in spring and last until September, October, or November.
Fleas in the house are typically found in sleeping areas such as bedding, carpet, and mattresses. Fleas on humans are often found in areas that are closer to the ground, as fleas tend to grab onto clothing while a person is outside.
Wildlife like skunks, squirrels, raccoons or opossums, can leave behind adult fleas or flea eggs when they spend time around the house, in the attic or your crawl space. Mice and rats can transport fleas into your home.
Not really, once again, adult fleas need to have food to survive. And your clothing isn't going to provide that for them. In addition to carpeted areas, fleas can be present in areas like pet beds, sofas, or other linens that your pet could have come into contact with.
Flea Dirt
Small red-brown or black specks on your pet or around your home may be a sign of fleas. While it could be typical dirt or dust, it's important to inspect. Flea dirt is flea feces. It often has a reddish hue due to the digested blood.
If you move into a new house or flat you can inherit a flea problem (fleas in the pupae stage can remain dormant for up to 9 months and hatch when you walk into an empty property)
Citronella, eucalyptus, peppermint, tea tree, and rosemary will all naturally repel fleas. If your dog doesn't mind a spray bottle, dilute a few drops of your chosen essential oil into a 300ml-400ml of water and spray directly onto your dog's coat.
Thoroughly clean areas where fleas frequently breed. This includes washing bedding, rugs, and pet bedding, and thoroughly vacuuming and sweeping floors and carpeted areas and along the edges of walls.
Using a DIY flea spray of apple cider vinegar on a rug or dog bed will not kill fleas of any life stage. That's because the acid in vinegar is not strong enough to penetrate the shell of flea eggs or larvae.
Fleas are so light weight that they can bounce right off the surface of the water because the surface tension of the water prevents them from breaking through. Adding the dish soap reduces the surface tension so the fleas slip through and drown.
Fortunately, washing your clothes, bedding, rugs and other textiles is an effective way to kill fleas in any of the four life stages, thanks to the chemicals in the detergent along with the heat and turbulence encountered during washing and drying.
Summer is one of the most active times for fleas and ticks, with some of the worst season being fall, in September, October, and November. Research has shown that the number of fleas on cats and dogs is 70% in the fall when compared to the spring season.
