After how many days do fleas die after drops for cats? - in detail
The lifespan of fleas post-treatment with cat drops largely depends on several factors, including the specific product used, the infestation level, and environmental conditions. Typically, flea control products like Advantage II, Frontline Plus, or Revolution work by disrupting the flea's nervous system or preventing their eggs from hatching.
Immediately after application, many of these drops start killing adult fleas within a few hours to 12 hours. However, complete elimination may not occur instantly due to the presence of flea eggs and larvae in the environment. These stages are often more resilient and can take longer to eradicate.
For instance, Advantage II claims to kill 98-100% of adult fleas within 12 hours and continues to work for up to four weeks after a single application. Frontline Plus also kills fleas within 12 hours and provides continuous protection for four weeks. Revolution, on the other hand, starts killing fleas in about six hours and maintains its effectiveness for up to one month.
It's crucial to note that while these products are highly effective, they do not instantly eliminate all flea stages present in the environment. Eggs and larvae can hatch over several weeks, requiring multiple treatments and thorough environmental cleaning to completely eradicate the infestation.
In summary, after applying cat drops, adult fleas typically die within hours to a day, but complete eradication of all life stages may take up to four weeks or more, depending on the product used and the extent of the infestation. Regular treatments and diligent environmental cleaning are essential for comprehensive flea control.
