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.
These fleas are most active at dawn and dusk, but they can bite at any time of day. Sand fleas can pierce the skin with their sharp mouthparts and then suck the blood out of their victim. It is common for them to bite people multiple times in a row, causing significant irritation.
Fleas may also nest in carpets, rugs, pet beds, or upholstered furniture where they can stay warm. Fleas and bedbugs are considered nocturnal creatures, which means they are mainly active at night. However, they can bite you at any time of the day or night. Fleas are most active at dusk and least active at sunrise.
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.
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.
Without a host like a cat or a dog, fleas can live anywhere between a few days and two weeks, but they can lay eggs that make the infestation last longer.
Flea Eggs Hiding in Carpet
To check for eggs, put on gloves and run your fingers through the carpet. Eggs tend to very small and white. Because they are so small, you may need a magnifying glass. Finding eggs throughout your house means you have a fairly serious flea infestation.
A 2017 study published by the Journal of Arthropod-Borne Diseases found that thyme and myrtle essential oils can repel fleas effectively. Cedarwood oil can also repel fleas from fabric, people, and pets, according to Healthline.
The light attracts the fleas, causing them to jump and land in the water. Adult fleas are positively phototactic, meaning they're attracted to sources of light. Adding a few drops of dish soap to the water reduces the surface tension. As a result, the fleas sink and drown.
Flea season starts in May and runs all the way into the winter when temperatures begins to drop below freezing. The worst time of the year is during late summer to late fall, from September through November.
Heat does kill fleas. They'll die in temperatures above 95°F (35°C).
In other words, different skin reactions, as well as the levels of gases, differs between humans depending on their genes. For example, some people may produce more carbon dioxide than others from their skin reactions, which is a common attractant to various blood-sucking insects and pests, such as fleas.
Flea bites may appear in a straight line or a cluster of many bites. Flea bites most commonly occur on your legs, especially your feet, calves and ankles. Flea bites rarely appear above your knee, unless you spend a lot of time sitting or lying down.

First up on our list of natural scents that will leave fleas running for the hills we have cedarwood. Cedarwood or atlas cedarwood are incredibly effective at both repelling and killing fleas. By using a diluted form of cedar essential oil, you can revel in the knowledge that the fleas will soon be very, very dead.
Fleas have a strong sense of smell, which they use to find accessible food sources. You can take advantage of this trait by using scents they dislike, such as cedarwood, mint, vinegar, clove oil, citrus, DEET, lemongrass oil, and rosemary oil.
Flea dirt looks very similar to coffee grounds. A quick test to see if you have flea dirt, is to place it in water. If it turns red, flea dirt is present, and this area should be treated. Also be sure to check any upholstered furniture and places where pets tend to rest and groom for live fleas or flea dirt.
They may come through with an old piece of furniture or clothing and skin of a person who already has been infested. Fleas typically don't use humans in particular as hosts, but they may travel through us. But fleas don't necessarily need hosts to enter our homes.
Pro tip: You can check for fleas around these areas by performing the white sock test. Put on some white socks and shuffle around the house. The heat and vibrations from your shuffling will stimulate the fleas and they will jump on you.
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.
Washing clothing and fabrics might not be a 100% cure for a flea infestation, but as long as you wash absolutely everything, it will take a sizable chunk out of the population.
