11 Best Flea Killers in 2021

Fleas are tiny wingless insects. They jump from place to place, and they are generally light brown or black. A flea’s life cycle has of four stages: egg, larva, pupa, and adult. The time for the maturity of fleas from egg to adulthood depends on climatic conditions. Fleas reach maturity between two and three weeks in temperatures between 80 and 900F and 70% humidity. In other weather conditions, it can take months for fleas to mature.

Fleas are parasites that suck the blood of a host. Hosts include humans and pets such as dogs and cats. Flea bites on animals can cause intense scratching, hair loss, and red and flaky skin. It can also cause tapeworm and anemia. Flea bites in humans can cause itchy skin and rashes.

Flea infestation occurs when fleas reproduce and multiply in the house. Pets can get fleas from the grass and bring them into the home. Fleas can also hide in carpets, furniture, blankets, beddings, or floor cracks.

There are different methods of eliminating fleas. Vacuuming, steam cleaning, and washing beddings with hot water can eliminate fleas. These methods require repetition or combination with other remedies to control fleas. Methods suitable for reducing fleas drastically include home remedies, chemical treatments, and professional flea control services.

Home remedies are cost-effective, and they use ingredients found at home. This method involves using salt, baking soda, dish soap, lemon spray, or flea repelling plants. Salt and baking soda are homemade flea powder for carpets, and they are also dehydrating agents. Sprinkle salt or baking soda on furniture, carpets, and flea-infested surfaces. Rub the salt or baking soda in with a hard brush and leave for a day or two for maximum effect. Vacuum afterwards and empty the contents in a sealed plastic bag. Dispose of the bag in an outside garbage can. Vacuum regularly for best results. Dish soap is also helpful in creating flea traps. Mix dish soap and warm water in a bowl and place the bowl in flea-infested rooms. The mixture traps fleas. It is best practice to do this at night because fleas are nocturnal insects.

Lemon spray can also eliminate fleas. Cut a lemon in thin slices into a pint of water and boil. Leave the solution overnight and pour in a spray bottle. Spray the solution on flea-infested areas. Allow the surfaces to become damp but do not soak. Flea repelling plants have compounds that fleas hate and will avoid. Plants that repel fleas include chrysanthemums, lavender, eucalyptus, cloves, etc.

Chemical treatment for fleas involves using pesticides in the form of sprays or powders to eliminate fleas. There are organic and insect growth regulator (IGR) treatments. Organic treatment includes diatomaceous earth, treatments with plant-based formulas, and permethrin. Permethrin is a natural compound that is present in the chrysanthemum flower; It eliminates adult fleas.

On the other hand, insect growth regulators have active compounds that kill fleas at all stages. Insect growth regulators have compounds like methoprene, hydroprene, or pyriproxyfen. These compounds inhibit the flea cycle, killing eggs, larva, and pupa. Active components in flea treatments can be toxic to pets, especially cats. It is best practice to air rooms after using chemical treatments before allowing pets or kids to re-enter.

Professional flea control services are the most expensive. This flea control method is effective because professionals know the exact treatments to use and the proper application method. However, individuals can carry out flea control in homes when they utilize the appropriate treatment and follow the application methods on the label.

The most effective application of flea treatments on carpets includes making space by removing all furniture. Afterwards, ensure that the carpet is entirely dry before vacuuming.
