During the day, fleas avoid the sun so they are most active at sunset and least active at sunrise. At dusk, the pests would lay more eggs, respire more, and move around in the yard more. Although the fleas are not completely inactive at any time of the day, they have increased activity at dusk and night.
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.
Fleas are also attracted to the warmth and carbon dioxide produced by their hosts, which can increase their activity at night. In general, fleas are most active at night and during the early morning hours, and this is often when pet parents notice flea bites.
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.
Flea bites do itch worse at night. This phenomenon is called nocturnal pruritus (nighttime itching). The cause is unknown, but may result from increased boredom, a rise in skin temperature, unconscious scratching, or circadian rhythms of cortisol levels.
Covering skin with long-sleeve clothing and pants will minimize exposure to bites. Flea bites often occur on the lower legs and feet, protect these areas with long socks and pants. Treat clothing and gear with products containing 0.5% permethrin.
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.
Fleas Prefer Areas That are Shady, Moist, and Humid
The truth is, most pets become infested with fleas when roaming outside. There is mixed information in terms of whether fleas live in the grass, but most researchers agree that fleas do prefer outdoor areas that are shady, moist, and humid.
Your Heat and Air Conditioning Betrays You
As long as a home is between 70 and 86 degrees (and pity the fuel bills for any homeowner who keeps the thermostat up that high), fleas will thrive.
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.
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.
Fleas are not attracted to some people, but other people are highly susceptible. Additionally, some people in flea-infested households may experience severe irritation from flea bites while others show no signs. Fleas bite people most often on the legs and ankles.
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.
Check shady, moist areas outside for fleas with the sock test. They tend to hang out in areas the sun doesn't shine, as well as under porches, shrubs, and around trees. Once you find out where the fleas are hiding, you can start to treat your house and your yard to rid yourself of the pests.
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.
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.
Use Certain Plants That Keep Fleas Away
You can do that by planting various plants that produce a natural scent that fleas are deterred by. This includes Chamomile, Citronella, Lavender, and Lemon.
Eucalyptus is so powerful that it can kill fleas and repel them, making it a worthy tool in your arsenal during every step of the process of treating a flea problem. For the most effective pest control, a eucalyptus spray can be used around frequent flea hotspots such as pet bedding and the corners of carpets.
According to extensive studies conducted at Ohio State University, vacuuming is indeed an effective way of getting rid of fleas! Through these studies, scientists discovered that vacuuming killed 96% of adult fleas from carpets and 100% of the flea pupae and larvae.
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.
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.
Only treating the fleas you see
Eggs hatch within 21 days and the larvae settle into fabrics like furniture and carpet. Here they will feast on dead skin cells and hair. Since 95% of the flea's life is spent outside the adult stage, flea infestations can take a long time to eradicate.
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.
