What happens to fleas after drops for dogs? - briefly
When flea control drops are applied to dogs, they typically contain active ingredients such as fipronil or imidacloprid, which disrupt the flea's nervous system, leading to their death. This process usually occurs within a few hours of the drop being administered, effectively eliminating the fleas from the dog's coat and environment.
What happens to fleas after drops for dogs? - in detail
Flea treatment for dogs typically involves the use of topical drops, such as fipronil or imidacloprid, which are applied directly to the skin. These products are designed to kill fleas efficiently and prevent future infestations. Here's what happens after applying these drops:
-
Immediate Effect: Once the drops are administered, they begin to work almost instantly. The active ingredients in the drops start to spread across the dog's skin and coat, providing a protective barrier against fleas.
-
Flea Exposure: When a flea comes into contact with the treated area, it absorbs the active ingredient through its body. This process is known as transdermal absorption.
-
Neurotoxicity: The active ingredients in these drops target the fleas' nervous system. They interfere with the transmission of nerve impulses, leading to paralysis and eventual death of the flea. This neurotoxic effect is usually rapid, causing the flea to die within minutes to hours after contact.
-
Preventative Action: In addition to killing adult fleas, many of these drops also contain ingredients that prevent flea eggs and larvae from developing into adults. This dual action helps to break the flea life cycle and prevents new infestations.
-
Long-lasting Protection: The effectiveness of these drops can last for several weeks, depending on the specific product used. During this period, any fleas that come into contact with the treated dog will be killed, providing continuous protection against flea infestations.
-
Bathing and Swimming: It's important to note that while these drops are water-resistant, excessive bathing or swimming can reduce their effectiveness. To maintain optimal protection, it is recommended to avoid frequent baths or to consult your veterinarian for advice on how often to reapply the product after bathing.
In summary, flea drops for dogs provide a swift and effective means of eliminating existing fleas and preventing new infestations by targeting both adult fleas and their offspring. Proper application and adherence to the recommended treatment schedule are essential for maintaining the health and comfort of your pet.
