Fleas, Ticks & Mites

  • Is NexGard and NexGard SPECTRA for Dogs effective when heavy flea infestations exist?

    Yes, NexGard and NexGard SPECTRA kill fleas rapidly before they lay eggs, thereby preventing further infestation of the environment. If a moderate to heavy environmental infestation exists, fleas can continue to emerge into the surroundings for weeks to months because of the continuing development of flea eggs, larvae and pupae already present at the time of treatment, a phenomenon known as 're-emergence'. It may therefore take more than one monthly treatment to achieve control of moderate to heavy flea infestations. In areas where fleas are common year-round, monthly treatment with NexGard or NexGard SPECTRA should continue throughout the year without interruption. To minimise the likelihood of flea re-infestation, it is important to treat all animals within a household with a registered flea control product.
