Are Fleas Resistant to Frontline Plus?

Are Fleas Resistant to Frontline Plus?

Frontline Plus has been around for over 10 years now. In that time it has performed admirably as one of a unique generation of flea control products that were powerful safer and more effective than their previous counterparts. However, some people are finding that Frontline doesn't quite seem to pack the same punch as it once aged to, leading some to maintain that fleas are becoming resistant to the drug.

In light of this, Merial (who accomplish Frontline) have been investigating reports of persistent flea infestations in Australia since 2005. If you have been using Frontline plus for three consecutive months without any other insecticides, then you may be eligible for investigation.

Despite all of these rumours of fleas becoming resistant to Frontline, Merial reports a high level of success in treated patients, with 92% of pets being cured of their infestation within a three month period. Given how difficult some flea problems can be to handle, this is a beautiful impressive statistic.

Even more engrossing is that these results are almost identical to the results first published from a Frontline top status spy in 1997, which showed 77% cured in 1 month, and 99% cured in 5 months.

This data may not be entirely suitable, because not everyone with a flea infestation bothers to find an investigation - often they will unprejudiced change products. So I can't rule out the possibility that there are dinky populations of resistant fleas out there.

If there were resistant fleas, you would reflect that there would be a noticeable decrease in the percentage of flea infestations resolved, but they remain quite high. This is why I detached recommend Frontline Plus for my patients - the numbers don't lie. Frontline Plus is unbiased as efficient now as it has ever been.
