Choosing The Best Natural Flea Treatments and Repellents for Cats

What Ingredients Are in Natural Flea Treatments?

Many of the most popular and widely used flea treatments for cats on the market involve synthetic active ingredients.

The EPA (Environmental Protection Agency) and the US Food and Drug Administration regulate all flea treatments (if the product is oral).

However, the EPA has recently come under fire from non-profit watchdogs for “inefficient safety criteria” surrounding some approved chemicals.

While many cats tolerate these drugs well, there have been reports of cat toxicity from flea treatments. Mild cutaneous or gastrointestinal discomfort to serious poisoning are all possible reactions.

These adverse reactions are more likely in cats with compromised immune systems, such as the aged, developing, and sensitive cats. Doing your study on what’s in flea treatments should be a priority for you as a cat owner.

While synthetic solutions may work well for your cat and create no problems, seeking for more natural alternatives when dealing with fleas may be better for some cats’ health.

Given the stakes, finding a suitable solution might be intimidating, so keep reading to learn about some crucial factors to consider when selecting a natural flea treatment and repellent for your cat.

Ingredients that fight fleas naturally

  • Cinnamon is a natural pesticide that is effective against a wide range of insects, including fleas. Cinnamaldehyde, the primary component of cinnamon, has been experimentally demonstrated to be poisonous to insects yet non-toxic to mammals. Furthermore, cinnamyl acetate, the component responsible for cinnamon’s signature fragrance, is a powerful pesticide and insect repellent.
  • Clove is a known pesticide that gardeners frequently use to protect their crops from destructive insects. This component may be useful in flea treatments for cats, but it should be used with caution because large amounts can be poisonous. If used with a shampoo, ensure that they are fully washed. If used as a topical treatment, only apply to areas where they can’t reach to groom.
  • The EPA actively regulates the use of cedar oil as a pesticide and in flea treatments. It has been proven to be effective as well as safe. Many insects are repulsed by cedrol, which is found in cedar oil.
  • Cottonseed: Cottonseed has been used as an all-natural bug repellant for millennia. Cottonseed is not poisonous to insects, unlike some of the other natural substances. It suffocates little insects and their eggs instead, making it an excellent addition to cat flea treatments.
  • Diatomaceous Earth: Diatomaceous earth is another non-toxic organic insecticide. Diatomaceous earth wraps little insects and causes them to dry and desiccate by removing them of their natural oils, rather than killing them via toxicity.
  • Neem: Although neem oil is not a key active element in flea control, it can be beneficial in repelling them. The inclusion of neem oil in natural flea remedies for cats improves the skin by hydrating it and functioning as an anti-bacterial and anti-fungal for skin irritations or infections.
  • While yarrow does not directly kill fleas, it can be a useful addition to natural flea treatments for cats. Yarrow oil and powder contain anti-inflammatory characteristics that may help with any subsequent illnesses or discomfort caused by flea bites on your cat.
  • Boric acid is a pesticide with moderate toxicity, thus veterinarians advocate using it as part of an EPA-approved product rather than a homemade cure. This manner, you can be certain that the amounts of boric acid in your home are safe. Boric acid is harmful to insects, but because fleas only feed on your pets’ blood, it has no effect on them. Instead, boric acid dehydrates invertebrate exoskeletons, causing death.
  • Spinosad: When this chemical is listed on the back of cat flea products, it is typical for people to mistake it for an artificial ingredient. Despite its unnatural-sounding name, it is a natural substance. Spinosad is generated from bacteria that naturally exist in soil. It is a powerful pesticide that is used to kill and repel various insects, including fleas. Because spinosad is most effective when consumed by fleas, it is most commonly found in oral products.
  • Peppermint: Because the strong aroma of peppermint components is effective at deterring insects, this ingredient can be a useful supplement to many cat flea remedies. Because peppermint possesses anti-bacterial, anti-fungal, and antiviral qualities, it can help minimize the impact of secondary infections caused by flea bites and skin irritation.

How to Get Rid of Fleas in Your Home

Because synthetic items are highly efficient, they are popular and widely used.

While natural products can likely have comparable results, some products may be ineffectual if not accompanied by additional household acts.

Unfortunately, getting rid of fleas on your cat is only half the battle. While fleas require your pet’s blood to survive, they can dwell in your home for 2 days to 2 weeks.

Furthermore, the incubation period for flea eggs can last up to 14 days. With these factors in mind, your cat is likely to pick up more fleas weeks after a successful treatment.

In addition to treating your cat, you should place an unpleasant mat for fleas in your home. Here are our finest recommendations:

  • Vacuum on a daily basis – following a flea treatment, regular vacuuming of floors and furniture will pick up any stray fleas, larvae, and eggs.
  • Steam clean – high heat will kill fleas at any stage of development, so using steam as part of your cleaning routine can be beneficial!
  • Clean all bedding in the house (both human and cat!) at least once a week to eliminate any fleas that may be hiding. Tumble drying after cleaning can also be beneficial because the heat will kill any residual living bugs.
  • Use repellents – Using repellents around the house will make your home a place fleas don’t want to be. It will drive away existing fleas and prevent new fleas from entering.
