Fleas are blood-sucking insects with flat bodies and long claws. They have special adaptations that allow them to get between the hair shafts of their host. In addition, fleas have spines on their legs, back, and mouth to help them move through the host’s hair.
Fleas can be very painful to humans. They can cause pain in the chest, abdomen, and muscles. They can also cause pimples and discolored blisters on the skin. Fleas can also transmit disease. Their bites can irritate the skin and itch for weeks.
Although flea bites are rarely dangerous, they can be painful and irritable, and if left untreated, can result in severe illness. The best way to prevent a flea infestation is to monitor your pets and keep the house clean. It will save you a lot of money and time in the long run.
Fleas are usually attracted to animals like cats and dogs, but they can also be spread from pet to human. Fleas can easily infest a home within a month. Moreover, they can also be transported to humans by wild animals like skunks.
A flea’s life cycle is determined by external conditions, such as temperature and relative humidity. The optimal environment for flea growth is 85% relative humidity and 85 degrees Fahrenheit. During the first stages, flea larvae do not immediately feed on blood, but instead feed on organic debris. As they grow, they start to feed on blood.
